Octane??

[GordoJay]

Only have 91 here

Yup. Because NA engines do just as well on 91 at altitude as they do on 93 at sea level. It's too bad, because with the turbos, we could enjoy a little better performance if we could buy 93.

On any turbo motor, run the highest octane available at the pump. Will advance timing and produce noticeably more power

 

[BambiKiller]

Can you add octane booster to 91 IDK ??

Yes. I like boostane personally. I think a bottle in a 35gal tank of 91 would get you to 95-97oct but don’t have the bottle in front of me

What are you guys running in your new raptor? 93 or 87

Always 93

 

[Justtoph]

Use Costco exclusively in all my vehicles. Supposedly top tier gas for quite a while now. (Won't pay a dollar more a gallon everywhere else.) Anybody had any issues that can definitely be pinned on Costco gas?

Never had a problem

I run 92 here in Oregon. Throw in a splash of boostane for a couple of couple more points. Stock tune, but my octane adjust ratio is maxed at -1.

forgive my ignorance but what’s better for your engine, 93 octane w/ 10% ethanol or 91 octane with no ethanol?

I go premium, usually 92 octane...I did notice that if I run 87 regulary mileage dumps like 3-4 mpg, so it is actually cheaper to fill premi6

No thanks love the mountains of Colorado

I am with you, I'll take 91 and mountains and snow over desert, especially after spending the last 2 years in the desert

Anything without ethanol is an improvement over 10% ethanol. It’s a $hitty fuel in our market
