Anyone Seen This In Oul Catch Can?

[DougS550]

I just checked my oil catch can (atmosphere vented only) and discovered about 4oz of what looks like a clear oil. FYI. I run ceratec oil additive which makes my Motul oil brownish.i put some in a clear glass with RO water, looks like clear water odd but I did start my car over the winter with E85 in the tank?

Fuel in the catch can is fairly normal, I assume that's just e85 getting past the rings into the catch can and evaporating and condensing into the can. E85 requires a lot more fuel than pump gas to be injected especially on cold starts. If you started it over the winter a few times but didn't really drive it, that's why.

E85 is a moisture magnet so you'll get this. Turn your oil cap over, you'll see what looks like milkshake.

Cold starts on my car, water is dripping out of the mufflers so much I have to put something down on my garage floor. The hot water has discolored my expensive garage floor.

My catch cans have what looks like rust liquid. It's from the E85, oil and the steel mesh inside the catch can. Mix all that together, rust colored liquid. I see your catch can doesn't have any filter material inside.

Here is a short of how much E85 can suck moisture into your system.

It was water and must have been from my weekly winter starts. A race shop I am at now says he sees that on Audi race cars on E85.

If on E85, it's imperative to get the car up to 212F (boiling temp of water) from time to time, or you'll sludge out your engine.

I run out of time to drain the E85 and put p3 in for the winter start ups. No issue though, car just dynoed perfectly.
