How-To: Perform And Understand An Oil Analysis

The Perfect Oil Change: Cheap Engine Insurance

Diesel engines are large investments. And because they’re an upgrade option on our trucks, SUVs, and passenger cars, they cost more. How do you protect that investment? One easy way to catch a glimpse of your engine’s overall health is through oil analysis. Most oil analyzers can test for wear metals (elements like iron, aluminum, and copper) to see if things like piston rings, pistons, bearings, or valvetrain components are breaking down. Particulate count tests, which clue you into what may be contaminating your engine’s oil (be it soot, coolant, fuel, or dirt), are also the norm.

The best part about an oil analysis is that it’s cheap insurance. It lets you know if your maintenance intervals are adequate, which contaminants are getting in (so you can stop them), and it can even give you a rough timeline of how soon you need to overhaul an engine. After uploading Green Diesel Engineering’s Eco tune to our ’05 Jeep Liberty CRD (which effectively disabled EGR) and adding a K&N air filter, we had a used engine oil sample analyzed. When compared to our previous (EGR-laced) oil analysis, we saw several improvements in the health of our oil. Check out the results below to see why you should be taking a closer look at your engine’s lifeblood.
