Oil Sample Testing
Does anyone use oil sample testing to determine when to change oil? I use it on my diesel truck to determine when to change my oil and what condition the internal working components of the engine are.

quite a few here do it although I think most of us use it to keep track of wear or possible problems. The oil life monitor seems to work remarkably well. Judging from my oil test results it's dead on!

I just use the oil life monitor. I think it works just fine to tell you when to change the oil.
