I am looking for input on fuel.

I have always used Shell 91 in my car. Do we have access to e85 anywhere in the GTA?

Are any of the 93 or 94 octane fuels available any better in practical terms?

Thanks,

Shell 91 is the best as it has no ethanol content. If you're boosted and running more timing then it's Petro 94.

Ken at Wedge Performance is recommending I go with 94 Octane with 10% ethanol as that would give better performance than Shell 91. I am gonna switch to Petro 94 and see how we do.

Our fuel quality sucks so if you are running a tune I would suggest taking some logs when cruising on the highway to see if you have timing drops and not just under WOT as most people do. I had a lot of timing drops while cruising on the MHD 93 tune when running Petro 94 (with new plugs, coils, injectors, walnut blast etc.). Logs look much cleaner on the 91 tune.

I only ever use Petro 94...even when mixing with e85
