Hey guys,

I can get 94 with Zero Ethanol across my entire province. I can also buy E85 in barrels for my garage. I'm in the process of tuning and pulleying my Hellcat (for pump) and don't want to do an E85 build as its rather inconvienent in Canada.

What would the benefits/risks and results be from mixing E0 94 Chevron w/ E85. I was thinking of doing 9 Gallons 94 and 1 Gallon E85 for a mix of around E08 . Local guys are doing this on their tuned Audis but I wasn't sure how our platform would react to it?

Would it be better/less risky than just running straight 94? Or is it more risky as it will lean the car out?

All opinions welcome.

There are times when the motor may knock on 91 even though it is tuned from the factory to run on it.

Heat soak+ high temperatures could cause preignition. Running more than 91 means less chance of the car pulling timing under those circumstances.
