This is a prime example of what I mean about newer oil being total crap. (thank you EPA)

This oil has around 50/50 of the ZDDP it had just 7 years ago so that's 50% less friction protection. Now they try to make up for it with moly but there is only so much moly can do, Nothing beats ZDDP.

This oil was ran 8500 miles / 13500klm all test are on the same oil. which is SN rated. Also notice the TBN at this mileage it's down to 1. You can run Mobil Delvac that same distance on a diesel and it will still be a high 7.




If it doesn't have at least 1000ppm zinc, don't even pour it in your engine. Find a better oil.
