E85 Experiment's

[Legacy777]

Hmmm that's pretty interesting!

Did they happen to tell you what kind of coloring?

Or ethanol in the states in pretty much clear all by itself, and will be a little brown/opaque when the gasoline is added.

They say that they add a red colour to the E85, to be able to see it when it's on fire.

I have not yet confirmed this. Supposedly, you should run your car on regular 95octane fuel once in a while, to remove residues from the E85.

I think my residue might come from my silicone boost hoses, but not confirmed yet.



*Edit* Maybe its my fuel-lines.. I dont have this black tar above the injectors..

[Legacy777]

Can you clean the residue off easily? Is it sticky, slimey....how would you describe it?

[Ubermeister]

I cleaned it off with engine degreaser, no need of scrubbing, just degreaser and compressed air.

Its a bit sticky, like permatex or a dried in splash of coca-cola.

I think something is getting solved up by the E-85, injected with the fuel and evaporated on the hot surface in the cylinder heads.

Have been running on E85 for maybe a year, about 1000km's/6200miles.

This is the first time i have the intake off after switching to E85.

Maybe i will take the injectors out after a few thousand miles anf check again..

[Legacy777]

Are you getting the E85 at the same station every time?

[Ubermeister]

No, its from different places.

Maybe just a bad batch of fuel can cause this, but its a fair amount of residue.

I can cut my fuel filter up later, and check. If its fuel-related, it should be black.

[Legacy777]

Yeah, I'd be curious to see what the fuel filter is like.

You may just try cleaning the residue and may have to check again to see if you can rule out a one time cause vs. a reoccurring issue.
