just get the knn intake for the gas saving so that you can put the 93 in it, youll get around 3mpg better in city so it will make up for the extra cost easy.
The whole intake..... It's about $300 but the gas savings more than make up for it in a short period of time. May take around a month or so for it to take affect, seems like your car has to reset the mixture of air and stuff when you put it on and undo battery.
my gxp loves 93 octane and it gave me the most power for the money.
Absolutely. Ethanol contains 76,100 BTU/gal where gasoline contains 114,000 BTU/gal. 10% Ethanol results in close to 111836 BTU/ga. The difference is not huge but it is there.
You will read about people making lots of power from E85 in a forced induction engine. That fuel while it has much less BTU's a gallon has a higher octane rating. You can simply burn a lot more of it to make up the difference. This allows for running more timing on more boost without knock retard.
i dont put anything but premium in any of my vehicles, even my n/a subaru that could probably take 70 octane. hell, i would put premium in my lawn mower if i cared about it.
Too funny. I put premium in my lawn mower and snowblower because I just fill up the gas cans when I need gas in the GXP.
I drive a lot of hills and when I don't use premium I get some crappy mpgs and it will flat out refuse to move anywhere near as fast as when I run premium.
i have always run 93 in my car. i dont think a little higher octane will hurt i run 93 and some really good octane booster in my GTP and it run perfect only did it like 2-3 times tho
I know this is GXP but my GT gets around 21 with 93 and a heavy foot
