What is everybody using for race gas? What us better l, oxygenated or non oxygenated? I've been reading on the unleaded race gases just there are after to choose from!

 

I doubt you'd ever notice a huge difference between oxygenated and non oxygenated fuels, maybe if you were doing fuel economy runs.

But run whatever you can get or find if you want to run race gas. Be it 100 octane, C16 etc etc.

 

I currently run Sunoco 108 but will be going with C14 right away

 

Leaded fuels kill your sensors from what I've read- we have 110 oct up here in michigan but it's leaded. I personally have not used it. Tempting but what are the gains really ?

 

Unless you tune for it specifically, I doubt the gains will be worth the high *** prices of race fuel now.

We've run MR12 in our race bikes on stock fuel map and lost a **** ton of power. Once the map is rebuilt though it's about a 9-12 rwhp gain.

 

That's what I thought -

 

I throw 5 gallons of C16 in the tank these days when I go to the track...at $13 a gallon that kind of sucks, but its good insurance. A lot harder to detonate and break **** with race gas in the tank.

 

i mix 93 unleaded and e85 in my 2012. i throw in some 100 unleaded at the track for good measure.

 

Aren't you diluting the E85 when you do that?

 

or maybe im diluting the 93? seems to like a 12.0 afr at the track.
