Do you guys buy the octane with the lowest, medium or highest level?

Does high octane gas gives you a better performance? Heard that it helps during winter.

I just get the lowest one because im cheap

 

all you need is 87 unless your running an f/i applied tC.

 

its not because your cheap, it says on the manual of your car to use 87.

 

There have been many threads on this subject----here is one: https://www.scionlife.com/forums/vie...ght=gas+octane

 

i think i wrote my answer in a few hundred places around the internet... along with quite a few posts here..

perhaps searching the word "octane" and browsing through some of the results.. you'll get an idea what you should use.
