Since my gas engine car does not have a cat con its not going to be a problem if i use it, but is this oil good fo 10,000 OCI on a 2012 montero sport of course with a bd28 filter partnered with it (my fathers car).

Also why is the more expensive (by 2-3x) Mobil 1 Turbo Diesel Truck 5W-40 fully synthetic oil have a lower TBN of 10.7?
Percentage does not equal ppm. No oil has 2500ppm ZDDP unless it's break in oil which is only run for a very short time and then drained. You would start to see wear in your engine with that high of zinc. Every company has there own math but I don't know what theirs is.
