or if the club, track, or series simply does not tech fuel, or if the test is a lead test, or if the rules are written to allow oxygenated fuel - which is what this engine was designed for and the cheapest fuel you can buy.
CKNA speicified which station you could take fuel from and calibrated their meter against it. It was E10.
Use 93 octane. I do, it works pretty well.
If you want to play it safe, just buy the fuel they sell there at your local track.
Personally I don’t, I use non-ethanol 89, but they don’t tech fuel at my local. If they did, I’d just buy my fuel at the track.
I would be very interested in knowing why you chose that fuel. What kind of racing do you do? I’m not trying to be a smart ass, but do you know what the term octane refers to? Please don’t take offense, there is none intended.
You’re always going to get the most performance from the lowest octane rating you can run w/out incurring detonation and/or pre-ignition.
