Race Gas

370zFORme!!

So I went to newport beach to buy race gas today. That's right 100 octane!!

Well $108 later the pump automatically stops, so I top it off just to be sure.
Get in my car, drive away and my gas measurement didn't go all the way up. The last light didn't light up. Weird, but anyway I gotta say, I can really tell the difference in Race Gas. Not like a performance boost, but just snappier and the throttle seemed a lot more responsive. Love it! Between the $100 oil changes and the $100 gas fill-ups, I'm gonna have to get a second job

Last time I bought race gas, I paid about $2 a gallon. Yeah, it was a looooong time ago.

Well the ECU does adjust certain things based on the quality of the gas so I suppose it is possible to see certain subtle difference when race gas is put in. Seems like a waste of money to me, but hey--why not!

lol, daily driving with race gas, hey if I could afford it I'd do it.

Ya I just wanted to try it out once, but now that I feel the difference, I might never go back to 91

ewww 91, we don't use that sh!t on the east coast

I know but that's all we can get here in CA, besides the occasional station that carries 100.

100 octane race gas is oxygenated, so yes it should perform better but octane proper only plays a small role.

I did the 100 oct once or twice in my bike but that only took $25 too fill up at the time. I didn't really notice a difference other than my exhaust smell had a sweeter scent to it.

You have to re-tune the A/F ratio to get the best performance, so you need an ECU that will do this automatically. If your bike had a manual tune you could have adjusted that.

Togo

I have a PCIII installed with a custom tune on my current setup but for pump gas (93) so yeah, I didn't really expect much of a difference when I did it.

unless you have a custom tune for the race gas, you are just wasting your money...

I'm not fighting the fact that it's a bit expensive, I would just rather put a mix of 100 and 91 to blend to like maybe 94 or 95 so that it's a little easier on my engine, rather than running on 91 all the time. I know our cars can run on 91, I just would like to give my engine a little bit more to chew on ya know?

Agreed...also, I would say a SC or Turbo kit running higher boost would see the benefits of race gas. Putting it an stock engine is a waste of money. In addition, you'll end up fouling out your O2 sensors faster.

The 91 is fine, the car will adjust timing if need be. Running race gas isn't getting you much if any power at all.
