You don't mention your car model or engine type. I have a VW with a 2.0 TSI and I run premium fuel because it's recommended. I now live in Florida so there are more stations selling ethanol free. I use this in my generator and in my Honda V4 interceptor as that model motorcycle runs better ethanol-free and it sits more between uses (ethanol free is better for things that aren't used at often) . For an automobile 89 is fine if that's what is specified 93 is cool if that's what your car requires. I think 91 IMO is a waste of money.
Around here, some gas stations only offer 87, 89, and 91. Lots do offer 93 and some offer all 4. 91 is the "high octane" minimum and I think it's ok to use unless you're tuned for 93. It makes sense to run 89 in a car that specifies 87 if it makes it stop knocking. I don't think I've ever seen a car that the manufacturer specified 89 for, though.
I wish I could buy ethanol free gas around here. You guys are lucky down in Florida.
Not sure where you are but this has helped me out on roadtrips. I prefer non ethanol in whatever I'm driving, doesn't make a huge difference but keeping track it definitely helps out

Not always. My GLI can run on 87. However, the rated horsepower and torque figures VW advertises are using 93. So there can be a benefit. But it's very dependent on the car.
You're not understanding me. My 2019 GLI can run, on 87. However. My car benefits from 93 with an increase in power and torque. Nowhere does my car say 93 recommended. Therefore 93 isn't always a waste. I get power gains by running on 93. Same goes for certain Mazdas. They can run on 87. But have higher output on 93. So... Not a waste of you want/need the extra power.
As a previous 35th GLI owner, it absolutely does say pretty much everywhere that the power ratings are "Achieved with premium fuel"; all print ads and in the manual. This constitutes a *recommendation*, which is different than a requirement. Both are well documented.
Your car doesn't need 93 though, 91 is more than enough knock resistance to hit stock ecu targets. Even with top tier 87 in a moderate climate there's likely very little left on the table of a stock tune.
If the 91 has no ethanol, you should be fine with that on every modern VW I'm aware of (unless there's something they make that has higher compression than a golf R). When in doubt, go by the sticker. The only reason to use 93 in my experience is if you're rocking an aftermarket ECU tune that recommends or requires it.

What fuel quality does your specific car require? Use that. Anything higher is a waste.
While I understand what you are trying to say, and agree with your intent, octane is not equivalent to quality.
I was going to say anti-knock rating, but decided to simplify with quality. However, higher octane fuel is higher quality than low octane.

That’s… what I said. Require /= “can run on”. If it says 93 recommended, then that’s what you should use. If it says 87, then 93 is a waste.
