Black CTS-V: Oil Report

Black CTS-V: Oil Report

I have my oil analyzed at Blackstone Laboratories every few years. The cost of the analysis is $28. You can mail the sample in any mailbox. I have always received my results in less than two weeks.

All of the samples I've taken have been of Mobil 1 5W-30 synthetic oil.

Here are the report results:
