Then again, it might just be simpler to change the oil after a long (many 100 mile) low speed run.

That raises the question of how much it takes to cause the pitting. Is it 100's of engine hours at low rpm or a dozen hours, and over what time period. Is it the engine sitting around for days afterwards?

You can never seperate the fuel from oil becuase they are both oils.

How much does it take for the pitting? Way to many varibles to answer. But from what I gather from Cat..basically your overhaul of engine can be due at a few thousand hours shorter than normal. Example..instead of 10 thousand hours over haul, maybe 7 or 8 thousand hours. But still so many varibles.
Sport fishing boats can troll at low loads which can be thousands of hours. They are made to do so with the appropiate rated engines. Yet they still have there issues..
Have your oil anylsed at oil change and if you are having corrision issues you will know from the test. Then you might catch some damage before it get's to out of hand..
