If you are ever in doubt of what wear metals are in your oils, the viscosity of the used oil, etc, this is the place to send a sample.

Done this recently for my Monte Carlo and my Suburban. Will be doing it with the red truck as soon as it's due for a change. Blackstone Labs is awesome, great people.
