Just today, I ordered Jake's Joe Gibbs DT40 5W40 oil. $153.55 case of 12 ($12.80/quart). Excited to try it. Will run it for about 2 years. Do mu UOA's and then decide if it is "better" than Mobil and Red Line. I am hoping it is. Charles and Jake say it will be. I trust them.

The UOA won't show it all. The reason for this is because there are no tests done for plastics in the oil.. We developed this oil from carrying out complete engine tear downs and measurements.
Particulate testing is one of the other tests that people generally do not carry out, or even know about but they provide a bigger picture concerning wear. We have not seen impressive differences between ANY oils when using UOA as a baseline, but we have seen dramatic differences in wear of all wear items within the engine, especially chain tensioners, wear paddles and the things that lead to real issues.
We developed the oil only for ourselves and our engine program.. I never planned to, or wanted to sell it retail.
