About Oil Analysis

Oil analysis is a quick, easy way to gauge the health of an engine (or any oil system) by looking at what’s in the oil. 

Established in in 1985, Blackstone Laboratories provides an easy-to-use, understandable, fast, and accurate oil analysis program.

At the heart of our program is ICP (inductive coupled plasma) spectrometry, database averages for comparing wear, and a comments section on each report that explains — in plain English! — what your results mean.

Use our free oil analysis kit to find engine problems, determine the oil’s condition, and more!
