Teardown #'s vs new factory specs and tolerances.
My point is many of these tests don't tell the whole story. I am not saying either product doesn't perform well.
Publishing the actual teardown #'s vs new would be more convincing as well as the parameters of the simulated 210k test. Speeds, hrs per OC, temps, rpm's, start/shutdown, cooldown/warmup cycles, etc.
Just to add, one other point;
An example, pure hwy driving results in an avg speed of about 50 MPH as published by EPA. City is just over 20 MPH.
In the Mobil 1 test, they only mention miles.
At an AVG of 50 MPH that engine would have 4200 hrs at 210,000 miles. At a pure city AVG of say 23 MPH, it would have 9130 hours, over double the hours.
That's 300 hrs per OC, or 652 hrs per OC. or somewhere in between. I think that would be relevant information
