E85

[vinnymac]

Hello all, has anyone ran a full tank of E85 or is it even possible to run. I have a 2023 AWD 2.0 and I am running 93 octane fuel now and I feel a greater amount of power than with the 87 octane fuel the truck came with. Any info is much appreciated tks VP

The Ethanol content is higher than recommended. Read the manual again.

If the vehicle doesn't have a Flex Fuel badge, don't use E85.

I tried something suggested on this site, for max performance I run 91 without ethanol, it's the highest octane available here. I filled up & when there was room I added 1-1/2 gallon of E85, I noticed it really perked up the Ecoboost. If the 93 you are using has no ethanol, then you could try this, if it's already E-10 then not so much.

Yep our 93 has 10% ethanol. We have a station that sells 100 octane racing fuel but at $10.00 a gal is crazy.looking for next best. Thanks

Found the owners manual and it stated no E85 at all but did say premium is good but keep ethanol at 10%

Yep just found my manual and that statement in there so premium it is 3.85 a gal not to bad. We have a local station that sells 100 octane but $10.00 a gal a bit to much

I don't know about Florida, but here in Kansas a few stations sell what they market as 93 Super Premium. (Our normal premium unleaded 10% ethanol is only 91 octane.)

It turns out that the '93 Super Premium' is actually E30 which is a 50/50 blend at the pump of E85 and E10 87 octane regular unleaded. E85 can vary from 85%-70% ethanol, so that's going to make the E30 '93 Super Premium' 40-48% ethanol. You can't run that without a tune.

Thats probably a bit much without a tune, my focus st was tuned for 93 & E30, but on the 93 tune if you got some crappy gas the tuner said to add a gallon of E85 to bring up the octane ratio, but bear in mind that was tuned, i would just get it tuned to be safe

It comes out to around 10% ethanol content which is what normal fuel is, some places selling 15% which will work in the EB, I don't know what the limits of the factory setup are, but I don't use more than 10% as mpgs suffer too much. I was curious if the small bump in octane would be noticeable, & it is. I also wonder how high of octane the factory computer would continue to adjust for.
