After 2 or 3 flights......yes,my plane is pretty messy. Several factors go into just how messy a plane will be,like type of fuel,where the exhaust comes out,tuning......stuff like that. You might notice your omega makes a very minut amount of more mess then the cool power. This could be because your omega has a little castor in it which doesnt burn up as good as the cool powers synthetic,but more than likely its just thier exhausts are sticking out further from the plane then yours,or are pointing in a different direction etc. And they may very well be running their engines alot leaner. Dont worry about it though....oil is good as long as your engine is running well. That means its getting good lubrication!

Check for a PM about my fuel details.....
