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?
