E85 or not?
I stand corrected on the concentration of ethanol and gas mixing, got confused because I run E85 exclusively. (Read right over the mix part when reading my manual) lol. My truck and I love it, smoother idle and noticeably increased performance.

Heres some education for you before you go spreading false information. E85 can contain up to 30% REGULAR UNLEADED, effectively making it E70. Flex fuel vehicles are designed to run on any concentration of ethanol from e10 to e85. When they make ethanol it is distilled to 95-99% pure alcohol which is 100% soluble into regular unleaded. There is abdolutely no harm in mixing fuel, thats how the vehicle is designed. Anything else is just opinion. I would agree that you shouldnt alrernate tanks, but if i go 2 tanks of e85 and then 2 tanks of regular that makes it ok as per the Ford manual? Use your brain.. Cheers!

- It is best not to alternate repeatedly between gasoline and E85. If you do switch fuels, it is recommended that you add as much fuel as possible—at least half a tank. Do not add less than five gallons
(18.9 liters) when refueling. You should drive the vehicle immediately after refueling for at least 5 miles (8 kilometers) to allow the vehicle to adapt to the change in ethanol concentration. If you exclusively use
E85 fuel, it is recommended to fill the fuel tank with regular unleaded gasoline at each scheduled oil change.
So referring people to the manual to read for themselves is best, because "mix them any way you want" is not correct per Ford.
In the 5.0 f150 I was told you can mix them any way you want. It makes sense to me because regular gas is e15 to begin with so if you add more ethanol to it, in any concentration up to 85% then it is safe to use. I just ran my truck 1500 miles mixing and matching fuels across America depending on price. Thing ran like a top. Anyone have other info that could be helpful?

The official required ratios of fuel advertised as E85 is 51-83% ethanol. Stations may sell anything in that range.
And if you alternate 2 tanks on off like that you will most likely be disappointed in your cost/performance. In case you care. (because both cost and performance will suck) If you really want to do this, just buy the E15 crap and save the effort. You may find it called 88 gasoline or some other weird name. "Useless" would be my name for it.
Regular gas can be E10, but it doesn't necessarily have any ethanol at all in it. We have plenty of stations that sell "100% gas." I don't particularly want to pay 91 octane prices for 87 octane fuel, so I usually buy E10 unless it's going in a tractor.

The E in E10, E15, E85, E anything = Ethanol. They don't just stick an E on it to make it look pretty.

Not sure what you're trying to say, but we have lots of gas stations that only sell ethanol-free gasoline. The price of 87 octane 100% gasoline is usually about the same price as 91 octane E10, and my Coyote doesn't care about the corn squeezin's, so I just buy 87 octane E10.

If E is an ANY part of the fuel description, it contains Ethanol. Why is that so difficult to understand?
