Casey’s E85 is legit!

[SubieRubyRoo]

E85 as we all know is 51-83% ethanol. Used my RevX ethanol testing kit for the first time today with Casey’s pump E85, and WOW! Sure looks like it’s right at 83% to me!

Makes the mixing calculation to E30 pretty easy!

Good to know.

I'm uploading an E85 tune to my mustang here in a day or two. Can't wait!

The 3.5EB in the 150s only have enough injector for about E30. The 2.7s must have the same injectors as the 3.5 because they can run true E85 with no changes.

3.5s need a bigger (>400lph) in-tank or a bigger HPFP, or both. Cheapest way to exceed E30 is a VMP Boost-a-pump that jacks up the voltage to 18-21VDC. Either in-tank solution is about $400 in parts plus labor if you’re dropping the tank. 36 gallon tanks are a handful…

Do big, brand-name stations "cheat" on their blends of fuel ? They get audited or spot-checked in many states so I don't think it's worth it for affecting their public perception. Any time I've seen a station that's caught doing things like selling 91 octane as 93 or 89 (mid) that's only 87, it's an independent, franchised station, it seems.

Pump E85 can have anywhere from 51 to 83% ethanol and be legally labeled E85. However, this large swing really can wreak havoc on people running boosted ethanol tunes that are dependent on a specific amount of ethanol.

I’ve never tested any fuels for octane, since those tests are outside the realm of DIY.

Ask in a Saab forum, they see calculated ethanol content in the dash with eSiD.

Must be nice Kalle. We don’t get that, at least on F150s intended to run straight pump fuel.

It was nice, miss my SAAB alot.
Here E85 consistently is 75%+ summertime and 65-75% wintertime. So mostly useful if you aimed for 30-50% mix.

Caseys is what I usually use. Just got a fil of the 91E10 yesterday. There newest station has all the flavors.

Boy that sure is nice, clear fuel!

Just my $0.02

Not only that but I've seen white papers that show ethanol below about 50% shows an increase in LSPI, but above that LSPI lessens with more alcohol. so more is better on a TGDI, especially if the engine might be susceptible to LSPI

I have the 5.0 coyote. I just got done running a return style fuel setup with ID1050 injectors. Along with a Paxton.

Should be fun and good for about ~800 crank hp. Give or take.

Yeah 5 Star Tuning says upgrading to the HPFP & 440lph in-tank but keeping all stock injectors makes the F150 fuel system good to 800 or so as well.
