Can we run E85 in our Rangers

[BJMartin]

Anything over ~50% ethanol will be a waste because the power/efficiency scale is a not a straight line, it’s exponential. Up to around 50% you are gaining a lot of the cooling abilities and the extra octane. After that you are adding a lot of fuel with very little return.

With my procharged f150 (flex fuel equipped, 550 whp) and my XKR175 (non-flex fuel, 500whp) I ran blended e85/91e0 mix to 93 octane, because regular 93 is not available locally. Both of those ran amazingly with the mix all year round with zero issues.

With my Ranger I’m running the same mix and getting 313/376 at the wheels tune only. I’m hoping adding the downpipe gets me closer to the 340hp I want. None of which would be remotely possible with the absolute crap regular gas we have around here. With a boosted motor, ethanol is race gas.

Hopefully someone come up with an ethanol content monitor that can be used on these.

I run 87 octane in my completely stock truck all the time. EXCEPT when towing a 4000 pound travel trailer I use the cheaper 89 octane E15 gasoline. I have found no difference in the gas mileage or performance. I think the slight boost in octane and cooling effect from the ethanol negates the lower heat content of the fuel.

I’m happy with e30…

At least where I live, the E85 pumps say "Contains 51% to 85% ethanol".
Owner's manual says not to use it.
I run E15 88 octane all the time with no ill effects, mpg is maybe 0.5 less than 89 but it costs on average 60 cents less than 89. I burn a tank every 4 or 5 days so for me it saves money.
If I can't get E15 88 then I get regular 89. Here all the regular gas is 10% ethanol anyway.
Ethanol-free, when you can find it, is about $1.00 more than regular 89.
I did run a tank of ethanol-free last month and topped it off before my surgery because it was going to sit for a month until I could drive again.

In order to run E85, the engine will most likely need the HPFP and LPFP upgraded, and potentially the injectors as well, plus an E85 tune. If you run it in a stock motor, you will run lean under load and cause catastrophic damage. Even E30 needs at least a tune.
