...so whats the difference between premium and regular gas?

everyone ive talked to says that its just bs and theres no performance gain



what are your opinions?

so many mixed opinions. the benifit of premium has already been expressed here, the major advantage of it is that it is a cleaner fuel. the regular fuel when put into an engine with a high compresion ratio or a boosted cylinder, will be more likely to detonate. the premium seems to be able to handle the compresion phase of the piston stroke a lot better without detonation. but that doesnt mean it wont happen. if you are running the wrong compresion ratio with to much boost it will still suffer detonation.
