I actually have a question. During the summer my friends and I go to a drag strip in Rochester, My question is this there's a Sunoco station in Weedsport that has 100 octane race fuel but my friend suggested 110 unleaded from our local airstrip. Can our cars run 110 unleaded or is it too high of an octane?
Honestly you shouldnt have to worry. Higher octane fuel doesnt increase the compression ratio, it just burns hotter faster. The quicker a flame can get to the piston, the quicker the combustion is = better power, less unburned fuel. If it says in my Stage 2 manual that premium fuel is recommended, then I'm going with the higher octane rating. The only problem that arises with me is: Will it make the engine run too hot? <- it shouldnt though... I'd run the 100 and see what you have. I ran 118 in my camaro with the stockv6 (3.1) 1992 model, and it made it smell like a racecar. lol
out of Chevron, Esso, Petro-Canada, and Shell, who has the best gas for 91 octane and higher. (weigh pros/cons).
mobil has the best gas, but it depends on how busy the gas station is (this goes for any gas)... you don't want to buy gas form a station that is rarely busy because it sits in their underground tanks for a long time. one other thing you have to watch out for that alot of people don't realize....
those gas pumps with only one hose... when you go and fill up at those stations, you are getting up to 2 gallons of whatever gas was left in the hose from the previous buyer. i never use these gas stations unless i'm in an area i don't know.
the octane levels with 1 gallon of 87 and 10 of 93 would be almost identical as 11 gallons of 93, but you get the cheap gas itself in there.
