I've been reading up on their materials lately, and it piqued my interest to find out if their Heavy Duty Diesel 10w-30 (code ADN) is a higher end synthetic just like their Signature series HDEOs. Based on my research here their SS oils are Pao/Ester based, correct? So is their HDD oils of similar caliber?
One thing to note of is this oil lacks the API-SN certification compared to their SS HDEOs, which has the API-SN cerfitication. That probably means that it has a stronger add pack, nothing indicating about its formulation though.
Any insider here that could shed some light on this?
