Never thought a simple oil analysis would change my tune on high-mileage engines
I was always the guy who said changing oil every 10k miles was fine. Then I sent a sample from my 1998 Cummins to Blackstone Labs last month. The report showed high copper and iron levels that pointed to bearing wear I could not see. Now I'm doing every 5k miles and using a better filter. Anyone else get humbled by an oil analysis?

Man that's the wake up call we all need sometimes. I did the same thing with my old Ford 6.0 and the analysis showed coolant in the oil from a tiny EGR cooler leak I would have never caught otherwise. Saved me a huge headache down the road. It's crazy how a little piece of paper can make you rethink everything you thought you knew about maintenance. Once you see the numbers there is no going back to guessing. Now I tell everyone to just spend the thirty bucks once a year and actually know what's going on inside that engine instead of hoping for the best.

Right?! Same thing happened with my old Duramax, the analysis caught high sodium levels from a leaking coolant seal that I never would have looked for. Now I'm the annoying friend who won't shut up about oil testing to everyone I know.
