Which Grade Fuel Does Your Ford V-10 Like?

[RetiredLEO]

What grade gas does your Class C with a Ford V-10 like the most? Better mileage? What brand preference if any?

We're lucky here in West Central Illinois (not Chicago Thank Heaven) A lot of stations sell a true old fashion gas without ethanol. Usually about 12 cents a gallon more but I'll pay that. It does give better MPG.
Missouri all gas has ethanol no matter what grade you buy per State Law. They don't even have to post it on the pump it has ethanol.
Regional Grocery Store Hy-Vee has gas stations next to their stores. Not stated but I believe it's unbranded Shell gas.

Mid-grade ethanol blend here in Colorado. I use mid-grade. I know that my pickup gets much better mileage when running on the unblended stuff but I have never tested our motorhome. Next trip I'll try it.

I have the V10 in a F350 and use the cheapest available, runs great, no reason to waste money on anything else.

Mid grade for me. Non ethanol if I can get it.

Regular as that's what the Ford manual calls for. No reason to waste the dough unnecessarily.

Brand makes no difference. Whatever is cheapest.
