Burnt oil

I just started flying with a DLE 20cc gas engine (love it ) but I hate the burnt oil on the plane. Does anyone know a good product or home remedy solution that will take the burnt oil off the plane. Thanks

gene6029 has good suggestions.
Windex also works good.

Of course it is an advantage to install the exhaust to minimize deposits on the model by directing the exhaust away from the model.

I have to assume that you already did that.

What gasil ratio are you using?

Mine spit out a bit of dark oil at the very first while it was breaking in, but now, very little. I'm using 30:1 Redline oil.

It is a yak 54 profile plane and there is only one way to install the engine, and that leaves the exhaust coming back on the plane. Simple Green, or 409 doedn't hardly touch it. Maybe it will get less when it gets broke in.

If you can post a picture of the engine and muffler installation, we can make suggestions.

I dont know why you are haveing such a time with getting the oil residue off. If the 409 wont touch it & if the plane isnt painted try MEK or 111Triclor. It will remove your paint though if its not covered with one of the plastic films. Carb cleaner will work also .....Gene

What works for me is mineral spirits. I fold a half sheet of paper towel several times, moisten it only slightly at the can opening, and refold to a clean area as needed.

I'll have to try mineral spirits. I have a G-26 that still spits that black junk. Traditional cleaners have been working, but MS may be quicker.

Traditional cleaners do work but not as quickly and easily as mineral spirits. What is surprising is so little is needed, which is a good thing as the stuff stinks.

A mystery to me is that the oil splatter off a G-26 or traditional gas engine seems to have a different nature than that off the Evo 10GX. That off the Evo seems to be more oily and less burnt. My guess is that it has to do with the ratio... at 20:1 the combustion flash doesn't burn all of the oil in the same way as happens with 40:1 is one supposition.

Another is that the Evo may be running cooler because of more oil content that carries heat out of the engine. That theory may be supported by observations that some of the guys who tried running synthetics at 100:1 in their big gassers experienced some cooling problems, but again that is supposition that the low oil content was the cause.

What does seem evident is that the Evo 10 is not prone to overheating.

My old G-23 and current G-26 are the only engines where I have noticed the problem. After the G-23 had some time on it, the problem went away.

The G-26 has low hours, but I assume that eventually it will be the same.

I don't mix my gas for optimal performance. All of my gassers are running on 32:1.

Do not use mek that stuff is very bad news. Try rubbing alcohol I use it with no issues. Also avoid any widow cleaner with ammonia as ammonia will activate the glue on monokote and cause it to loosen over time

Thanks to everyone for the input !, The mineral spirits works very well, I take some Simple Green and wipe up after the mineral spirits and it's ready to go again.
