Running E-85/Flex Fuel
« on: July 21, 2016, 06:10:52 AM »
Has anyone on here converted to Flex Fuel? My local Sheetz has E15, and E85. I was wondering if our cars can use this, ive heard newer cars ie 1980s and higher can actually run e85 without new lines and the such. I'm pretty sure this is incorrect, but i wanted to run it by you all before I ruin my fuel lines/filter.

Also thanks guys for being patient with me. I see you guys as mentors so your opinions are amazing, considering I don't have anyone to teach me this stuff.

You could run E15 with no problems, in fact most gas that is available in Wisconsin is E10.

If you put E85 in, it won’t do any damage to fuel filter/ lines/injection system, but it won’t run in our cars either.

E85 has about 30% less BTU’s of energy compared to the equal volume of regular gas. So in order to run it, you would need to provide 30% more fuel.

Flex-fuel cars have an additional sensor that detects the ratio of ethanol/gas, the ecu then uses this sensors data to determine the proper amount of extra fuel to add depending on the E value of the fuel in use.


As for running E85 in an engine designed to run on regular gas, it doesn’t make sense.  In general E85 costs 80% of regular gas but only gets 70% the mpg.

IMHO…. The real benefit to E85 are it’s high octane levels and it’s use as a cheaper racing fuel than regular race gas.
With E85 you can run more boost with lower risk of knock or run an N/A engine with 14:1 compression.

That's good to know, everything i've ever heard is you need steel lines to run E15 and higher since it destroys rubber. I knew about needing the sensor/tune.

You would need to build the car specifically to run E85. Larger injectors & custom tune are usually in order. You also get 30% worse gas mileage :/ But the effective octane rating is higher.

Like Chris said E10 is what is available at most pumps these days. I believe the gov't is pushing real hard to make E25 standard soon.

Dont know about e85 on capri. But i had run my 2001 ford mondeo 2.5l v6 duratec enginge (europe) on e85 for round  about 50.000km. There were absolutly no problems. I used larger injectors and an additional ecu which was put in between the injectors and the original ecu. It uses some information from the obd like coolant temperature etc. No problems with cold start or something else. With e10 the cars needs about 8-8,5l on 100km and with e85 it needs 10-10,5l on 100km.
It was cheaper than with e10. But from april 2016 germany wants to have extremly high tax for e85 and so e85 cost more than e10 and so it not realy intelligent to drive on e85 and its clearly unpossible to find a petrol station which sells e85. 
I am sad about this because e85 is a realy high performance fuel. In germany we had a lot of tuners who used it. Like VW Golf 1.8l with more than 1000hp. They drive with more than 4 bar (58psi) turbo boost. Thats only possible with e85 because of the very high octane rate.

In my capri i use aral ultimate 102. It has an octane rate with about 102.
