I wonder if these folks are buying higher octane gas than their car needs when gas is cheap, or buying lower octane gas than their car needs when gas is pricey.

- eitally 11y agoI drive a car that only requires 87. When gas got down to $2.00/gal, I tried 93 for a couple tanks in a row, just to see what it did for mileage/power. The result: a 4Runner is a big, brick-shaped SUV and will drive like a big, brick-shaped SUV no matter what gas is in it. I switched back to 87.
- modoc 11y agoLower octane fuel actually has more energy per volume, so if your car's compression is low enough for 87, using 93 just gives you less power and worse efficiency.

- Retric 11y agoMany cars are designed to take more than one grade of gas, generally with some acceleration trade-offs. Another consideration is you can significantly impact mileage based on driving habits and expensive gas is a reminder not to be overly wasteful.
