I added 1 quart of oil to my already blackish 6 quarts this weekend before I flew. An hour later while I was filling up with fuel, I noticed some dripping under my plane. It turned out not to be from my plane but while I was checking things out, I put my hand on the inside of the cowl at the exhaust outlet. The oil that vented out of the engine through a hose that exits between the exhaust pipes was fresh oil. That is, clean, not mixed with the rest of the older oil in the engine. It was a little disheartening to see that my newly added oil was the first to be vented out of the engine in flight, as though it never had a chance to mix with the older oil already in the engine.
Does this seem right? Any reason it would happen this way? The only other thing I would not is that the engine was pretty cold that morning when I added the fresh quart. The oil was very slow to enter the engine through the dip stick tube.
Thanks. Andy
