I'll tell you place you can get really good gas...
That Mexican resturaunt behind the BP on 116th. Practically blew my coworkers out of my office, today!
Seriously though, I've heard that putting too high of an octane in the car is quite bad for it. I use premium in both my bikes and my NSX. But, I've heard most of the Japanese built cars that are brought to USA are built to run on 91 octane. Anyone know anything about this?
