Oil Change Interval Thoughts

[Dave_H_M]

I just got back my Blackstone analysis and it looks like the on board indicator (computer that says life remaining) gave a pretty close indication of how much farther I could have run the oil.

So I been wondering if there is any way the computer figures the numbers based on the type of oil you are running. What if I stop in at Kooter's quick change and he dumps some bulk stuff in there that has been refiltered and did not have the additive package updated. Will the computer give the same indication as if I had Motorcraft branded stuff in there?

My guess is that it will.

Anyone know the answer?

Your thinking is correct.... BUT in every test that I have seen, the factory OLM has been proven to be VERY conservative. And these are on forums where they posted the actual Blackstone reports.

Just use a quality oil in your expensive truck, and follow the OLM.

I'd agree
