One more thing... does the */C require premium, or just recommend it (Series I or II), just curious, no I'm not going to go out and buy a */C Bonnie.

Car says use Premium Only. But regular with a bottle of octane boost should surfice

My Yamaha Raptor 660R says Only Premium OR better, but ive ran regular a few times with no ill effects

But I'm sure your MPGs and your vroom vroom (performance) will suffer if you use regular. What is octane boost?

U can get little bottle of stuff called octane boost. it raises the octane level of ur fuel. And u can get Cetane Boost for Diesels.

Huh, interesting. I am reading reviews 'bout the '95 (I don't know why, I guess I have nothing better to do) and they say that the naturally aspirated has 205 hp, and the Supercharged has 230, which I know only the Series II has those numbers. Is the Series I or II in the '95?

The supercharged 95 has the Series I @ 225 HP.

Oh, but naturally aspirated has that Series II, I wonder why they would do that, I guess just didn't perfect the supercharger on the Series II?

The Series I and Series II both came supercharged as well as naturally aspirated. It sounds like your source may be incorrect or confusing. Try this link. http://en.wikipedia.org/wiki/Pontiac_Bonneville

Yeah, that'* what I meant. The '95 Bonneville naturally aspirated had the Series II, while the Supercharged versions had the Series I.
