I'm currently deployed with the Army so I don't have the ability to check into these questions with my own two-hands, and I've exhausted my online search using Google.

For an F350 with the V10...

1) Does Fords warranty prohibit the use of E85 with its V10 engine?
2) How much of the fuel system is not teflon-lined or steel?
3) Is the fuel tank made out of high-density polyethylene?
4) If any parts of the fuel system are rubber/plastic; are they made of, or do they have: high-density polyethylene, teflon-lining, or tefzel?

You cannot run E85 in the V10 period. It's fuel management system is not set up for it even if the lines and what not could handle it.

Thanks for your service!!!!!

 

Ken,

Thanks for the quick response but...

When you say fuel management system, do you mean the fuel/air mixtures calculated by the trucks computer?

If so then I know of at least two sources that provide programmers specifically dialed in for E85.

Claims regular unleaded gas and E85 (ethanol variant). No personal contact to verify claims other than looking at website.

Claims one or the other use of unleaded gas and E85 (ethanol variant). Have had indepth dialogue with tech-designer.

If that isn't the case, what did you mean?

Hmmmm. Interesting link, and interesting issue.....

 

You might have better luck asking these questions in the Alternative Fuels forum here, they seem to really know there stuff. Here is a link:

No Phil, that's what I was talking about. If a person can find a PCM that will work then I'm all for it.

I cannot answer your other questions with any real certainty. I will say that if the parts for e85 compatibility are more expensive then they are not on the truck.

I will also say that if a guy buys a V10 F350 then he more than likely needs the power to tow and haul. Using E85 will lower the specific power output too won't it? What's the point then? If you want better mileage or a lower cost per mile you'd be better off getting a vehicle that is already equipped to handle E85 and save the V10 for times when the ability to do a job is more important than the costs to do it. Just my $0.02.

 

The PCM settings can be changed with a programmer though, with two applications dedicating the trucks onboard computer to one specific fuel at a time.

I know that Diablosport makes one, and so does SCT.

I think that you will see that the horsepower gained by using E85 over regular gasoline is superior. Allowing you to tow just as much weight if not more, while your engine works less to do so.
