It sure does not! Im pretty sure its okay for 87 on 04 plus even if its a gtp. My gas door says unleaded okay i believe. Im out of town and don't have it with me but i wouldn't run 87 if te sticker says premium only. I might be wrong tho but im almost sure it doesn't say premium only

That pretty much sums up that premium fuel is required for all supercharged vehicles.

I would buy a fixer upper. but i wouldn't know how to fix her

My 2000 doe's,

Also, running 87 in the L32 is going to chip pistons in the long term if you run the car hard.

Running 87 can hurt your car badly

Keep running 87 and do a few WOT pulls. Knock knock... Who's there?

Mr. Piston

The price difference between 87 and 91+ is what a few bucks extra at most if your filling the tank all the way. Sure cut corners.. To save $3-5 then b*tch about chipping a piston and then having to find another motor.. Sounds legit.

And why is that they made the series 3 different to be able to take 87. If it was bad for the engine it wouldn't be in the owners manual. It wont hurt the engine just my opinion. I think GM knows better.

Same can be said for tranny flushes... GM recommends it what every 60k IIRC... But everyone knows that a flush is a bad idea.. And that a pan drop, filter change is better.. So answer that question. Ask Mr Dan what happened to his transmission shortly after this "flush". But I guess your gullible enough to believe everything in the manual.. I bet when something breaks on you GM isn't going to tell you it's on the house at no charge.

We aren't trying to knock you. We just are trying to enlighten you before you **** something up

I know its good to know this information. And yes from now on 87 will be last resort! I understand because my car runs a lot better with 91! But yes definitely don't want to damage anything

Well just burn 87, drive like a grandpa and listen to the gentle clunky sound from the engine at every stop in traffic.
