Best unleaded from the approved fuel list for turbo Stocker?

Considering a 2015 Ecoboost Mustang for I/J/K Auto.

I see Sunoco 260GTX and VP C10 on the list. Anything else I should be considering?

Neither are probably worth the effort/price to find consistently for any performance gains you think you might see.. We tried them both with no noticeable difference over just running the easy to find and "cheaper" Sunoco 110 purple. If you're looking to squeeze every last HP out of it, this might be worth the effort, but based on your other post it seems like this car isn't going to be a record holder or anything like that.

I'm sure others will have another opinion as fuel is something that many people differ on, but this is just with my experience for what it's worth.

But this car has an O2 sensor or two, that will be used by the stock engine computer for closed-loop operation, and I don't want to be fouling them and replacing them...

If you can by higher quality ones that still interact correctly with the OEM computer that wont be as big an issue as you think it is. We're running and late 80's 302 EFI car and have had zero issues with both the OEM computer system and the new Holley system we put on with running leaded fuel and killing O2 sensors.

Maybe we've just been lucky.. I'll have to look into the O2's we ran with the stock system, but we are running the NTK O2's with the Holley.

My question was kind of turbo-specific, but thanks for the input, Brad.

Frankly, it should be able to run under on pump 93, with or without a little octane booster for insurance, but pump 93 isn't on the approved list.

Does NHRA conduct fuel checks only at national events, divisionals, or what?

They check fuel at divisional, national and national open events in stock and super stock so you will have to run an approved fuel. Pump gas is not legal to run in NHRA competition.
With the new regime taking over in January leaded fuel will be going away soon so hopefully the fuel suppliers are working on unleaded fuel for our type of engines.
