Line Up and Wait
It is pretty funny how this changed from a Q & A session to a "my junk is bigger than yours" kind of thread. To this I will add the following:
1. OP, if your oil is turning black in a short time but there is no smoke or residue, you are probably ok. Change it at 25 hours like many and I'm sure that you will be ok unless your oil temp is high and you are cooking it. This is from years of working on cars and boats, but not airplanes so take it with a grain of salt.
2. Everyone else in the argument.... I always had fun listening to my dad talk about the engineer that refused to listen to the simple Icelandic immigrant with a North Dakota farm education (graduated in '53) when he was warned about the location of the injection ports on the rocket motor that my dad was welding up for their test. See, dad worked on everything from the Voyager series to the Viking lander, shuttle and many of the satellites that we use every day. The difference? Dad was a simple welder with 4 decades of experience but no degree. It always struck my funny when an engineer would take us to dinner as payment for the bet that my dad won even though he wasn't smart like the engineer? Many a rocket motor went BANG or at least failed inspection because a book smart guy failed to listen.
When I was working as a test engineer at a deep sea instrument company I helped design more than one set of plumbing for a ship when queried by an engineer with a Phd as to why temp readings from the bow inlet port were lower than the readings midstream or at the exhaust port in the stern. You should have seen the look on the guys face when this AS degree holding guy asked the PhD guy if the plumbing was routed through the engine spaces and how close it was to the engine or exhaust.....
Just because a guy has a lot of letters behind his name doesn't mean that his way of looking at things is perfect.
