Generallyabove 5K feet you can run 2 points lower, less dense air is the key. If I were still living in CO I would run 85 in a stock car.

I ran 85 in my 2004 Buick from the get go. It ran fine, no pinging. 2 weeks after I traded it in on the GT, the salesman called all pissed off saying it blew up. It was a fine car with 40K on it when I traded it. I don't know whether to believe him or not. I will always wonder if the 85 did something to the valves.

The salesman actually called you? I would have asked him if he bought the extended warranty when he took it as a trade-in... Same thing he would be asking you if it was reversed....

I would have laughed and told him you sat it at redline the whole way to the dealer. TFB all sales are final muhahaha[sm=laughat.gif]

Yea, he went on to say that they should have test driven it. I told him that they did because it was moved when we got back from the GT test drive. They held the Buick's payoff as hostage for 30 days until I called em and told them that I would get my cousin the Attorney General involved. Payed off in 3 days after that.
