Anyone compare mpg using higher octane fuel? I'm guessing this non turbo motor will not benefit unless you are in very hot climates.

I think its been shown many times that its not worth going for a higher octane than your engine requires. There's just nothing gained from it on a stock setup.


However, I've been driving a couple turbo cars for 10 years now. Anything less than premium octane doesn't even register in my mind anymore.

I have a kia non turbo that gets better MPG using mid grade. 2-3 MPG
