any problems with running e85? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Not worried about the mpg because e85 is a lot cheaper than 91 so it somewhat evens out. I'm more worried about any side effects to the motor.

Again, the answer to that is "none so far", and there is only one way to find out what the long-term results will be.

Not that I'm the OP, but I have JDL UEL, and OFT E85 and it rips. Very noticeable power difference. Mileage sucks, but it's about a buck cheaper than 93 so it evens out. I'm going with a Motoeast flex fuel kit and ecutek though. Nothing wrong with OFT, just want flex fuel so I'm not locked in to a specific fuel grade.

I've been running the same setup for a few months. What kind of mileage are you getting on E85? I've been averaging about 19 MPG. Been having some cold start issues when the temp drops into the 50's. I think I'll be switching back to 93 when AutoX season is over.

Chad11491 · 09-20-2015, 07:02 AM

I'm getting about 19 when I'm all city, and about 26 on the highway. Before I was about 24/31.

I've done a bit of reading on this as my GTR runs on e85. In short.. as long as you drive it regularly and run a tank of 91/93 thru it every couple months you will be fine.

What if I've been running e85 for 90% of the time. As soon as I hit 1k miles I swapped to e85. Now I'm at 13,6xx. So basically my car has only seen 1k miles of 93. I have no issues but should I switch back to 93 to be on the safe side?

humdizzle · 09-21-2015, 07:23 PM

yeah i would. The real key is driving it regularly though. When you let it sit for weeks the e85 draws moisture out of the air, and it condenses as water at the bottom of the tank.

how are you driving it year round in nyc? you don't have any cold start issues in the dead of winter?

NyC Zn6 · 09-21-2015, 07:34 PM

I don't drive my 86 for the winter it gets garaged Nov to march. Yea I get the cold start issue in fall when temp gets low.

Yeaaaahhhhh, it's probably not a great idea to let E85 sit for 5 months.

Ashikabi · 09-21-2015, 11:08 PM

No problems with e85 BUT out of the 6 months ice been using it, I have yet to get 85% ethanol.best I've had is 80% so I would not run a tune for 85% without flex fuel. If it's for 70% should be fine to my knowledge

Before it gets stored I run down the tank as low as I can go. I start the car 3 to 5 times a week and I let it run for 10 min or so. I fill up a 2 gallon canister with e85 for March when it returns to the road.
