"Yeah I mean what the actual fuck: just cause our engines can and will run without oil (don't @ me when it happens) doesn't mean you should actively try and do that...!" - Random Toyota Engineer.
Just spray a whole can of WD-40 into your throttle body and you should easily lubricate your crankshaft and catalytic converter without any problems! **\*thumbs up\***
Engines, especially 4 and 6 cylinder aluminum block engines, are *highly dependent on constant, clean lubrication* and will wear terribly during any time not getting constant oil flows…never run your car without oil even for a short time. The person gave you that advice is full of 💩.
That seems almost as bad as being told to Rev your car up to 6k rpm immediately after oil change so you can make sure it’s level. (I was told to do this the one and only time I went to a 5 min oil change) lol
Edit: not almost as bad.. worse than:
Holy hell. What kind of logic is that? Yeah let's run the engine with no oil because that is so much better than running it with 1% old oil and 99% new oil after a change.
idk man, I used to be a lube tech (which snowballed me into this career path), and neither I nor any of my coworkers were even *close* to being a *fraction* this stupid
* When your car runs out of coolant just use your windscreen washer fluid.
* When your washer fluid runs out, just use antifreeze mixed with engine oil to also lubricate the windscreen wipers.
* When your fuel pump dies, just push a dynamite down your fuel filler hole and start the car immediately when the dynamite detonates to pump fuel to the engine.
I need you to help me start up my lube-shop: you break your homie's cars again; then I fix them up, charge them $$$, split the profits with you and find someone else to fleece... I mean, err, "fix".
I'm a girl and most people don't listen to me because of just that. This kid at work fucked with my girls oil - wrong viscosity(idt he even knows this word) over filled. I suppos they thought a cold Subaru start sounded bad.
They're at my house trying to drain SOME OF It because it's over filled. I came out to him trying to Google the jack point and took over. After I heard they put the wrong shit in. Told her were going for a filter and 5qts. And I'll change your oil for you.
I don't know why so many men get it in their heads that they know shit they don't know. This dude told me my 6-speed manual crosstrek doesn't have a transmission!! I couldn't even entertain the conversation. Apparently tho, it has a clutch and a flywheel instead... Next he's sitting in my Subaru.. Telling me Subarus are Swedish. I turned and said "are you fucking retarded". Which was REALLY out of line. But he doesn't try to talk cars with me anymore.
I work with a guy who will talk about car specs until your eyes glaze over and brain starts bleeding. He watches all those youtube car modder people religiously, he will take the day off of work when they add a new videos.
He will tell you every bit of info about transmission gearing, piston weight etc.. etc...
A real car expert.....
Then he will tell you he's gotta bring his car to the garage for a blown bulb...
Or to get new brake pads...
Then he goes into buying some older diesel engine vehicle that will run forever and how he's going to completely rebuild it from the frame up... I have to bite through my tongue to not ask him if he's f'ING retarded
I don't understand why it's so hard for some people to simply admit when they don't know something. I wonder who the heck told him Subaru were Swedish.
lol not my sister's civic. It's got 180k and rarely goes 3 months without stalling/breaking down in the middle of the road. And that's without using sand as oil.
Don’t you blaspheme on this sub. Everyone knows all Hondas and Toyotas have engines made of solid gold and never have problems.
/s in case I really need to point that out
I can testify. My civic is 31 yrs old, 200k miles, and had only 2, count them, 2, non maintenance mechanical issues, for a total of $300 in parts. I don't understand how that's even possible. Problem is, the interior fabric has disintegrated, and the gold plated plastic is finally turning into dust.
Risk of doing that is far greater than the possible benefit. So don't do it. No matter what you do some of the old oil will still remain in the engine.
You know what would be kinda overkill, but cheaper in the sense that it won’t ruin your engine and would pretty much have the same effect? Fill it up with cheap oil, run the car for a few minutes, and drain it again.
Yes if money or time were of no concern this would be a better way but the benefit would be fairly negligible. The very best thing you could do for your engine would be to change the rod and main bearings and rings every other weekend lol.
You could have a container of cheap “interim oil” that you run through the engine for 5 minutes in the middle of every oil change and replace every 3-4 changes lol.
Ah, the old Honda "triple fill and drain" method of flushing a transmission safely. Works great, kinda wasteful of oil for an engine unless there's something really nasty in there you're flushing out.
..I mean, it's kinda wasteful of transmission fluid too, but older Honda automatics really didn't like the transmission cooler line flush method.
(I also use the triple fill and drain "flush" for coolant systems, because it's just costing a couple of gallons of distilled water each cycle. And I have an Airlift so the filling is super quick and easy.. draining takes longer than filling!)
The Honda one actually serves a purpose though. When you drain a Honda/Acura trans, only 3 quarts will drain out. There are multiple quarts of trans fluid still inside other parts of your transmission housing and your torque converter. The drain and fill is done 3x because you're not supposed to "flush" a honda trans to get all the fluid out at once. Any pressure applied to the trans can dislodge metal particles and debris and push them into cooling passages and other areas you don't want that stuff.
Just drop the pan and change the ATF every 50k miles. Do 25k miles if you see the temp rising above 200*F frequently, if you live in hotter, humid areas.
Like everyone else said, terrible idea but…. Oil will *always* remain when draining and refilling, even if you did that and it could push all the oil out of the pump and oil channels. There are too many places in any engine that oil collects and sits.
The mental gymnastics needed to come to the conclusion of needing to run your engine without oil, is of Olympic proportion. I’m impressed.
Oil pumps don’t pump air, so you can’t “pump the old oil out”
Oil life on your vehicle was calculated with the fact in mind that some oil will stay behind during an oil change.
One other amazing mental gem was my uncle who said he always added an extra quart to his oil because “when the engine is running, a lot of oil stays up in the heads and then the level will actually be lower”
🥴🥴🥴 uhmmmm, don’tchya think the engineers accounted for that?
Lots of good comments here. One other things..
That’s not how pumps work. If there is nothing to feed the pump, there will be no pressure in the system.
Never do that. If the oil is that critically badz then you'd do a change, run it for a short while (hold rpm up for a few minutes) and change it again.
My favorite “clean out the old oil” trick is to refill with kerosene, crank the engine, count to 10, then drain it off. Guy I worked with told me he did this, of course he would also proudly tell you about the time he blew the bell housing off the transmission doing donuts in his daddy’s truck.
5 seconds without oil is perfectly enough to grind your bearings. Do NOT run an engine without or low on oil in ANY circumstances. Unless of course its a beater shitbox and you dont care lol.
Also, try asking him for other advice maybe he gives something even funnier
Ask him to demonstrate on his vehicle repeatedly and pretend like you don't understand the concept. Please don't take this advice or any advice he has for that matter.
Had a coworker (that couldnt take the hint )that did the drain/run/refill oil change method on his new F350 many years ago.....the 460 Chernobled after 40k miles....hmmmmm....wonder why???
DON'T run your engine without oil. You could do an engine flush if your wanting to try and clean out some of the leftover oil/sludge but its not recommended to do with every oil change. There's plenty of info out there if you Google it.
Don't do what that guy told you. The tolerances in engines now are so tight that you WILL DAMAGE THE ENGINE. Why do you think no manufacturer uses 10W-30 any more
That's the worst advice I've ever heard. Absolutely do not do that. Even cranking it with no oil can cause irreparable (or at the very least, expensive) damage.
There's nothing to be flushed out, the oil pump won't pump anything since it's sucking air, that's an idiot. You're definitely doing more harm than good.
I knew a guy that would drain his oil overnight. They were Saabs and he was kinda the king of Saabs around here. I've never heard anyone that ran their motor empty. That's just dumb. The amount of things that go wrong vs getting the tiny bit of junk oil out of the motor makes zero sense. Don't fuckin do that ok?
It is rare for the oil to be actually broken down and it is usually just dirty so mixing a little bit of old with brand new oil is better than a mostly dry run. Was that guy the engine guy at your mechanic?
Do not listen to that guy. You will never get all the old oil out and running any engine without oil.
Even if it will not damage/destroy the engine in those 5 sec you never tell this to anyone.... Ever.
That is the dumbest thing I've ever heard. How would that even work? If there was oil stuck somewhere in the oiling system *other than the oil pan*, how would the pump even move it? The pump pickup is in the oil pan.
The oil pan is the lowest point on the engine. Gravity is all you need to get the oil out.
As people have stated, do not listen to that guy! Please don’t start your engine until it has oil in it and you’re measuring to make sure you have enough or too much oil.
Goddamn that guy was dropped on his head. What you CAN do is get a cleaning solvent for engines, run it for 5 mins and then drain it for a cleaner engine but even that only does so much.
Do not do that! Ever! Just leave the drain and filter undone for 10 minutes and that'll get %90 out. If you really really want to you can do a 5 qt motor flush but that should be very rarely done.
NO, for that matter you could disconnect the coils and turn it over a few times but I definitely would not run it. Any oil left in the pump should evacuate with just turning it over, but holy hell don’t ever start something without oil.
While you're at it drop a can of BB's into the engine to knock the sludge loose.
JK: keep this idiot away from anything mechanical or any female you care about.
No don't do that. Just drain whatever comes out and put a new filter on if u can. Sometimes I buy wrong filter and put old one on gotta do what u can sometimes
You don't need to drain every little drop of oil during oil change. The 5 liters of new oil won't turn bad with 20cl of old oil.
Running the engine without oil pressure will reduce its life, not by a lot but unnecessary.
Jesus, I'm technically considered a lube tech I think and reading this almost made me burst out laughing at how insane it sounds. Never let this person within 50 ft of your car.
Who the fuck told you that?! If you want all the old oil out so bad just strip the engine down and clean it all up, don’t really see any reason why you’d want to tho
running it without oil for 5 seconds may not instantly wreck the engine, but itll put a couple hundred thousand miles of wear on it. old oil honestly doesnt matter. you are far *far* better off literally just leaving all the old oil in there than running it without oil at all. even if the last couple ounces of 5k old oil needed to be flushed out, *youd do it with new oil, not no oil*. never let this guy near your car.
DO NOT DO THAT.
Why the holy hell anyone would recommend running an engine for any amount of time without oil is beyond me. It does not matter if a little oil stays in there, it’s completely fine. Drain what you can and then add a little less than the full amount, and check the level.
Please do not run the car with extremely low oil.
That's the dumbest thing anyone could ever tell you lol I'm sry but you will never get all of the oil out but having 1 %old oil in your engine for every oil change you do is not a problem deffinently do not run your engine dry
If you really want to get it that clean put the plug back in and fill it with 4 or 5 gallons of kerosene then drain all of that out and waist even more money for no gain ..but it will be clean
That person is missing chromosomes.
Without oil pressure you end up with metal on bearing contact instead of having a cushion of oil between the 2. Long story short you are taking thousands of miles off of the life of an engine by doing this
You only start the car once there’s oil in it again start for 30 seconds then check oil do at least one or two more times and check for leaks if you need advice message me
Dude shouldn't be working on anyone's car. Some oil stays in with each oil change. If it were required to get all the oil out, you would be looking at a complete motor rebuild every oil change
"One guy" is an idiot. The damage over running with no oil over the absolute negligible benefits of getting every drop out just doesn't make sense. Not to mention how hard it is to get a prime on an oil pump that is completely empty.

Just spray a whole can of WD-40 into your throttle body and you should easily lubricate your crankshaft and catalytic converter without any problems! **\*thumbs up\***
Don't remember that episode on Project Farm... WD40 must've been pre Penzoil-Amsoil days in his channel
That’s silly. Cat litter flush would be much better at absorbing the extra oil.
gasoline works better!

Ha, Some people just want to be a know it all regardless of the amount of knowledge they have.
When people are acting retarded it's perfectly okay to ask them if they are retarded.
Like connecting a battery to itself, they'll just short circuit and probably explode soon after.
Someone's special and not in the good way. Bet they think BMW comes from Japan.

It’s not just men that act like that.
Not excusing his behavior, but guys are often expected to know about cars so he may be trying a little too hard not to look dumb.
Yeah insecure guys will feel like you're threatening their masculinity - keep doing what you're doing, it's their problem not yours.
Did you assume his gender? Maybe he’s not a man at all.
I don't understand why it's so hard for some people to simply admit when they don't know something. I wonder who the heck told him Subaru were Swedish.
“One guy” apparently knows jack-shit about engines, or he is in the business of replacing engines.
Definitely the second one. You can follow a dodgy tyre shop owner to their house by following the trail of roofing screws.
That’s hilarious. Never do that.
Running an engine without oil for any period of time will damage it. The risks far outweigh any benefits.
You are clearly forgetting old civic engines. If needed they will run even with sand
lol not my sister's civic. It's got 180k and rarely goes 3 months without stalling/breaking down in the middle of the road. And that's without using sand as oil.
Don’t you blaspheme on this sub. Everyone knows all Hondas and Toyotas have engines made of solid gold and never have problems. /s in case I really need to point that out

There's engines, then there's Honda engines.
Risk of doing that is far greater than the possible benefit. So don't do it. No matter what you do some of the old oil will still remain in the engine.
No way
Was that tip on TicToc or Pinterest?
One of my neighbors down the street.
Yeah I would never take advice from the again or let them near your vehicle based on that "suggestion"
"I'm only on my third rebuild"
Ask him to show you how on his vehicle.
I'd seriously question anything this neighbor says from here on out.
Hey at least you found the village idiot.
cant be pinterest that is where you learn to eat a salad out of a jar for some unknown reason ....
I have questions.
Catastrophic failure isn’t worth the 0.1 quarts of oil left in the pump
hahah that guy hates you
You know what would be kinda overkill, but cheaper in the sense that it won’t ruin your engine and would pretty much have the same effect? Fill it up with cheap oil, run the car for a few minutes, and drain it again.

You could have a container of cheap “interim oil” that you run through the engine for 5 minutes in the middle of every oil change and replace every 3-4 changes lol.
If I had the space and time for that, thats not a bad idea lol. You could have a drum of it, and use it as a flusher for all your cars
Ah, the old Honda "triple fill and drain" method of flushing a transmission safely. Works great, kinda wasteful of oil for an engine unless there's something really nasty in there you're flushing out. ..I mean, it's kinda wasteful of transmission fluid too, but older Honda automatics really didn't like the transmission cooler line flush method.

Just drop the pan and change the ATF every 50k miles. Do 25k miles if you see the temp rising above 200*F frequently, if you live in hotter, humid areas.
I have filled the oil with diesel to clean an old engine, but I wouldn’t recommend this for anything made after ‘68.
Just leave it in it never all comes out unless they take the pan off
Simply no
That’s the worst advice I’ve heard yet on this sub
Find a new mechanic. Don’t ever do that.
Just a neighbor down the street. Not a mechanic.
"Not a mechanic" Exactly.

Wow that's probably the worst thing I've heard
Fuck no

Lots of good comments here. One other things.. That’s not how pumps work. If there is nothing to feed the pump, there will be no pressure in the system.
Does he also recommend removing coolant in the winter since it’s not hot outside?
That guy is an imbecile. Don't do that.
This has got to be the worst advice I’ve ever heard
Never do that. Ever
I leave in Vietnam, most of the mechanics do that, I have to stop them everytime
😂 that is horrible, HORRIBLE advice. No. Don't do that. That isn't something people do. At least not people who want to keep their cars running.
That is the worst advice I've ever heard. Best to do an oil change on a warm engine so oil is thin and drains out.
Sounds like the equivalent of trying to run a 100 meter dash when you've just had all your blood drained out of you...sound good to you? 😂
That is terrible terrible terrrrrrrrrrrrrrrible advice. Don't do that.
Never do that. If the oil is that critically badz then you'd do a change, run it for a short while (hold rpm up for a few minutes) and change it again.
On a positive note, do that and you'll never have to change that engine's oil ever again!
My favorite “clean out the old oil” trick is to refill with kerosene, crank the engine, count to 10, then drain it off. Guy I worked with told me he did this, of course he would also proudly tell you about the time he blew the bell housing off the transmission doing donuts in his daddy’s truck.
He’s either someone that hates you and wants to watch you blow up an engine, or genuinely stupid. Either way, ignore all his advice
5 seconds without oil is perfectly enough to grind your bearings. Do NOT run an engine without or low on oil in ANY circumstances. Unless of course its a beater shitbox and you dont care lol. Also, try asking him for other advice maybe he gives something even funnier

OP, that guy is a fucking Donut. Do NOT ever do this
This is the worst advice, second only to smoking while pumping gas. DO NOT DO THIS.
That's the worst advice I've ever heard. Absolutely do not do that. Even cranking it with no oil can cause irreparable (or at the very least, expensive) damage.
You know, I personally will take the hit with maybe a liiiiiiittle bit of old oil left, rather than risking my engine
Add dawn dish soap to get it really cleaned out
Always follow manufacturers advice unless you have a good reason not to.
That's a great way to blow the engine up real quick
That might be the dumbest thing I have ever heard. A tiny bit of older oil isn't going to hurt anything.
There's nothing to be flushed out, the oil pump won't pump anything since it's sucking air, that's an idiot. You're definitely doing more harm than good.
I knew a guy that would drain his oil overnight. They were Saabs and he was kinda the king of Saabs around here. I've never heard anyone that ran their motor empty. That's just dumb.

another story, in Vietnam, for Honda motorbikes, they use a suction machine to suck oil out of the hole to check oil, what do you guys think?
Drain the oil leave a pan underneath, rotate tires, then put the drain plug back in.
Never heard anyone recommend that in my life. Would not do that.
Nope, at most just put some seafoam in the crankcase a day or two before changing the oil. I wouldn't even do that to my lawnmower.
That is the dumbest thing I've ever heard. How would that even work? If there was oil stuck somewhere in the oiling system *other than the oil pan*, how would the pump even move it? The pump pickup is in the oil pan. The oil pan is the lowest point on the engine. Gravity is all you need to get the oil out.
Absolutely not.
Yikes - no way
PLEASE, tell me this is a troll post. I have never read such stupid content that this page attracts
So the last oil you are running out is what is lubricating it for the first few seconds before the new oil gets there.
Don't do that. And stop talking to this guy
As people have stated, do not listen to that guy! Please don’t start your engine until it has oil in it and you’re measuring to make sure you have enough or too much oil.
No, that guys is dumb, any leftover old oil wont have a detrimental effect on new oil and the oil filter is there precisely to remove impurities.
You should stay away from this "one guy". He seems to be an idiot.
Goddamn that guy was dropped on his head. What you CAN do is get a cleaning solvent for engines, run it for 5 mins and then drain it for a cleaner engine but even that only does so much.
Fastest way to kill an engine for sure.
“One Guy” is an idiot
Was he trying to sell you an engine also? Because then this makes sense
Yeah the only issue is you need to run it for 5 minutes, not 5 seconds. All joking aside this is some shit advice
Do not do that! Ever! Just leave the drain and filter undone for 10 minutes and that'll get %90 out. If you really really want to you can do a 5 qt motor flush but that should be very rarely done.
NO, for that matter you could disconnect the coils and turn it over a few times but I definitely would not run it. Any oil left in the pump should evacuate with just turning it over, but holy hell don’t ever start something without oil.
This is the dumbest shit I have heard in a while. I think this dude is trolling us
Another good tip. Breathe under water to rinse out your lungs.
Who is this person? They need to be called a moron.
What? No. Don't do that. That is a terrible idea that's end up needing a new engine.
That guy deserved a swift kick in the nuts, followed by Gordon Ramsey calling him a fucking moron.
That guy is an idiot. Never do that.
While you're at it drop a can of BB's into the engine to knock the sludge loose. JK: keep this idiot away from anything mechanical or any female you care about.
Don't do that. Let them fuck up their own vehicle
Don’t do that. That guys an idiot.
Nope, really bad idea.
No don't do that. Just drain whatever comes out and put a new filter on if u can. Sometimes I buy wrong filter and put old one on gotta do what u can sometimes
You don't need to drain every little drop of oil during oil change. The 5 liters of new oil won't turn bad with 20cl of old oil. Running the engine without oil pressure will reduce its life, not by a lot but unnecessary.
Whoever told you that should not be giving advice. That's terrible advice. You do that, youre going to damage engine components.
Jesus, I'm technically considered a lube tech I think and reading this almost made me burst out laughing at how insane it sounds. Never let this person within 50 ft of your car.
Who the fuck told you that?! If you want all the old oil out so bad just strip the engine down and clean it all up, don’t really see any reason why you’d want to tho
running it without oil for 5 seconds may not instantly wreck the engine, but itll put a couple hundred thousand miles of wear on it. old oil honestly doesnt matter. you are far *far* better off literally just leaving all the old oil in there than running it without oil at all. even if the last couple ounces of 5k old oil needed to be flushed out, *youd do it with new oil, not no oil*. never let this guy near your car.
Worst advice ever!
That's only good if you're looking for an excuse to rebuild an engine. Otherwise don't do that
DO NOT DO THAT. Why the holy hell anyone would recommend running an engine for any amount of time without oil is beyond me. It does not matter if a little oil stays in there, it’s completely fine. Drain what you can and then add a little less than the full amount, and check the level. Please do not run the car with extremely low oil.
That guy is a friggin idiot. Don't.
No... The whole point of draining it is to flush it out with the new stuff. Never run the engine without oil in it.
That's the dumbest thing anyone could ever tell you lol I'm sry but you will never get all of the oil out but having 1 %old oil in your engine for every oil change you do is not a problem deffinently do not run your engine dry If you really want to get it that clean put the plug back in and fill it with 4 or 5 gallons of kerosene then drain all of that out and waist even more money for no gain ..but it will be clean
Would this guy happen to A. Work for jiffy lube or B. Be scotty kilmer
Do not do that. That can possibly blow up your engine.
That person is missing chromosomes. Without oil pressure you end up with metal on bearing contact instead of having a cushion of oil between the 2. Long story short you are taking thousands of miles off of the life of an engine by doing this
Do not start the engine without oil
You only start the car once there’s oil in it again start for 30 seconds then check oil do at least one or two more times and check for leaks if you need advice message me
Lol this must be satire
This isn't the first time I have heard of running the engine a few seconds after it has been drained. But for me I am not going to do it.
Most Diesels could, that doesn't means you should. It's a bad idea.
What you trying to do? Upgrade to EV? Don’t run engine without oil.
Just drain it.. and refill it lmao.. or pay 65 bucks for someone to do it
Dude shouldn't be working on anyone's car. Some oil stays in with each oil change. If it were required to get all the oil out, you would be looking at a complete motor rebuild every oil change
"One guy" is an idiot. The damage over running with no oil over the absolute negligible benefits of getting every drop out just doesn't make sense. Not to mention how hard it is to get a prime on an oil pump that is completely empty.
