I got a full tank because it was cheap (3.36) and now my car is running like shit . Stay away from the big racetrack on Pleasant hill =/
unless it's actually from a track that people buy it from, it usually sits in the tank for a LONG TIME. also you won't really see any benefits from it unless you are setup to run it (more boost, timing, etc)
haha, yeah im talking about racetrac ie. the gas station company. FTL. I floored it today and my car was like get the fuck off the gas.
Throw some toluene in your tank. I threw 2 gals in with 14 gals of my normal Citgo premium and got 5mpg better fuel economy than the last tank of straight premium. I'm baffled, the car loved the added octane, made more power, and got better fuel economy at the same time. jk, this worked for me but is no way economically viable or even statistically sound, just a fluke occurrence.
