About Oil Analysis

Oil analysis is an easy way to find out what’s going on in your engine (or any oil system) by looking at what’s in the oil.

Blackstone Laboratories has analyzed more than 2 million oil samples since 1985.

People are at the heart of our program. Every report is written by a human (not AI!) and explains in plain English what your results mean.

Use our free oil analysis kit to see what’s happening in your engine!
