How long can i likely push my oil?

[BlackBeard]

Well I would pony up for a used oil analysis, I know everyone says change it but no ones acknowledged that his is severe duty. Light short trips in cold climate is the hardest thing you can do on your engine. I would do 4K tops but say once a month you ran a long drive to burn off any moisture

I have been doing 10K (miles) for 38 years with Mobil 1 oils in all types of engines. Never had a problem, and some engines had quite a few miles on them.

This isn't interesting, and there's no article.
