AMSOIL AME 15W40 (CI-4+) Heavy Duty Diesel and Marine: TBN 12.10
AMSOIL DEO 5W40 (CJ-4) Premium Diesel Oil: TBN 8.00
AMSOIL HDD 5W30 (CI-4+) Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil: TBN 12.20
AMSOIL PCO Synthetic Blend 15W-40 (CI-4+) Heavy Duty Motor Oil: TBN 12.10
You can see how the new CJ-4 oils for 2007+ emissions with particulate exhaust filters are a compromise in oil TBN to help meet emissions. That's why if you don't have a particulate exhaust filter, you should try and run a CI-4+ oil rather than a CJ-4 oil. The TBN (Total Base Number) will drop as your oil ages and acidifies with use. It is basically a measure of the condition of the base stock in your oil.
