I've looked and looked on the forums for this and haven't found it. I thought somebody else might have asked so if it's already been posted somewhere just point me to the thread.
Thanks

Is the new Delo rated SM? I saw some SM HDEO of some sort the other day that was API SM. If so, it's light on the ZDDP, under 800PPM? Someone correct me if I'm wrong. That ZDDP content standard may also be GF4.

Ok, ok, I'm wrong! I said I might be..
But, at least it inspired the aquisition of the CORRECT answer..
YOU'RE WRONG. The SM rating in other than the GF-4 grades has NO phosphorous limits, thus NO ZDDP limit.
Delo 15w40 LE will have about 1200ppm of ZDDP.

Question:
What is API CJ-4 and what is different about it?
Answer:
The EPA has mandated changes for 2007 diesel engines and API CJ-4 is the corresponding diesel oil specification. CJ-4 is [an improvement over the previous CI-4 Plus API specification, although chemical limitations have been put in place for CJ-4. The reason for these chemical limitations has to do with the fact that 2007 diesel engines have a new device on the exhaust system. This new device is called a diesel particulate filter (DPF) which is designed to greatly reduce particulate emissions of diesel engines. Sulfated ash, phosphorus, and sulfur additives have been limited

Why is DEO more expensive than other AMSOIL diesel oils?
Answer:
It is more expensive because the new additives used to replace zinc and phosphorus cost more. Additionally, supplemental dispersants and anti-oxidants are included to meet the API CJ-4 criteria.

Just the low sulfated ash formulation will contain lower ZDDP but for this oil your fine.

I'm just disappointed I didn't teach you better.
