Blackstone Lab Report

Recommended Posts

Assuming this Lab is reputable, I just received the report on my '04 C2 that has 58,000k on it with 1,800 miles since last change (5w40 Mobil1) and all is way better than their universal averages for a 3.6 motor.

Maybe a temporary relief as the car has not had the IMS replaced, but a relief all the same!

Blackstone does good work. I've been using them for about 7 years.

Your report is soooooooo good because your 1,800 miles is probably about 1/2 of the miles they use for the Universal Averages.

What 5W40 Mobil are you using? Turbo Deisel?? That's a good oil because of the higher zinc and phosphorus levels vs 0W40. Keep using it or go to the Joe Gibbs DT40 5W40.

And keep doing your UOA's. One report (even a good one) won't tell you much. You need more reports and data. Buy in bulk from Blackstone. If you buy in bulk of 6 tests......that average out to about $19 each.
