Did you know that 2007 and newer model diesel engines must use oil requiring API CJ-4 emission quality oil standards? Did you know Mobil 1 does not have a synthetic oil to meet this new standard yet?

Amsoil just happens to have one specifically to meet these new low sulfur oil standards. Amsoil DEO 5W-40 Premium Diesel Oil. Check it out when you get a chance.

Yes, you can use this oil in the older diesel engines.
