Just thought I would pass some info on from an experiment I have been doing for 3K now. The truck is a 2004 4.6 2wd and I have been slowly shifting from E-10 to now E-47 which is equal volume E-85 and reg unleaded E-10. I have experienced no appreciable loss in mpg (18-21 hwy) and the truck seems to be running the same, no loss in power, rough idle or CEL's. The only thing I don't know is how much further I could go and if I could be running in a lean situation without having a check engine light come on. I currently don't have a way to check for a lean code. I'm happy with this mix now since it's easy to calculate how much of each I have to add to get the mix I want.

Just thought I would pass on the info for those who would like to shift towards ethanol for the principal.

 

Playing with fire.

 

Unless ur truck is E85 (Flex Fuel) compliant... then you are Playing with fire as i.ride.suzuki said above.

 

4.6L is NOT an E-85 compatible engine. And that sort of thing is NOT covered under warranty for sure...

 

"Playing with fire" is an accurate assesment. Vehicles that are designed to run on high ethanol content fuels have lots of components that are different from unleaded gasoline vehicles. Ethanol destroys rubber compounds (like gaskets and seals) and it is also conductive (unlike gasoline). Running it through a system not designed for it will eventually destroy your engine and if your electric fuel pump should develop a short, will eventually lead to a fire. This isn't conjecture, it's fact. You are sitting on a time bomb.

The above posters are all correct. One other VERY, VERY important thing to note about corn based fuels is that they are CORROSIVE to untreated aluminum (read not ANODIZED)! So your fuel lines, fuel rails......

 

I think I am going to experiment with running diesel in my F150

 

propane too

 

LOL ..

 

All the above warnings are correct. I work for a large automotive supplier and have discussed this with an associate in fuel pumps. Ethanol has a much higher moisture content and will corrode your fuel pump. Do not be surprised if your fuel pump (and possibly entire fuel system) takes a dump on you.

I'd change back to regular gasoline immediately if I were you... and cross your fingers that you didn't screw things up too bad already.

PS - just in case you weren't sure, the comments about diesel and propane were jokes. Don't try those either.

 

 

When you see the , you can always assume its a joke with me...

 

aint seen a truck fire in a while...be sure to keep your camera handy for us!

 

ya... I know... but if he's crazy enough to try ethanol, he might be crazy enough to take you seriously!

 

Awesome, tomorrow I just might try running my pick up with water.
