But Diesel is almost the same price, and in some cases cheaper? than premium gas. Plus in the summer I drive about 60 miles a day plus more on weekends.
if that's the case, it's probably worth it. around here, last i checked, diesel was more than premium. keep in mind you don't need to run premium in many gas cars.
I looked at it...I did not like it. The interior wears in the funniest of ways.
I understand, but the GTI I am sure would need premium. Right?

Shouldn't need premium so much as recommend premium for best performance. If you are not driving with all of the power the engine makes then there will be no difference to you. ("Need" would apply to older cars though.)

But you don't want to take a chance especially with a turbo engine.

That's not how it is. The only difference between an engine recommending high octane and one not asking for high octane is that that engine has the capability of advancing its timing enough to take advantage of the higher octane. Of course if you're buying the car for its power then you won't get all of it when using lower octane, but if you're buying it for other reasons then it won't matter to you...and we're not talking about a lot of difference anyway. Either way the computer advances the timing until it detects a slight amount of knock and backs off slightly.

Really? So you won't damage it? What about a high compression engine like the SVT, Civic SI, and the prelude.
