What gas are you using?

[Azholley]

I have been using 91 octane from Costco. Didn't notice a difference from 87 personally.

On a side note, not to hijack but some say Costco gas quality is poor... is this true? I sure save A LOT of money filling my massive tank up there.

Costco is a top tier gas buddy! You're good [emoji1303][emoji1303]

I have used 87, 89, 91, and 93 in my raptor and honestly can't tell a difference. I drive it like I stole it (avg mpg stays around 12-15 no matter which fuel I use) so it's not like I stay away from the powerband. I haven't tried towing with it, or driving in hot ambient temps yet, though. So those could be affected by the lower octane fuels.

You'll notice the difference in the long run. Especially with direct injection vehicles.

I think I'm going to put 91 and call it a day

Looks like I'll be filling up at Costco or QT

Same here...zero difference in fuel mileage thats for sure. I have only towed with 91 or higher in it.

How does DI impact vs port fuel ? Given this has both.
