But it looks like the formulation has changed since last year, They have two different specs one from last year and one for this year. This is due to the API rating. And as you can see the CI-4 is superior it's TBN is 12 while the newer CJ-4 is only 10. Damm EPA!!!

Fortunately you guys can't get get good stuff all day long.

I would not use the Delvac 1, on a JDM diesel , It simply cannot keep your engine as clean.
I think the ones being sold here are still CI-4 rated. Noted that Mobil 1 Delvac is not suited for our Japanese engines. It has always been my thought that since it is an expensive oil and that it is manufactured by one of the leading diesel engine oil makers then it should outperform and exceed manufacturer's engine requirements. I've been using Mobil 1 Delvac for 3 years now. Maybe that's why I observed that in just a matter of days after changing oil when I check the dipstick the oil is already black.

Hoping I can get hold of the Fleetguard or Baldwin filter before I do my oil change. If not then I will still use the OEM filter and will open up the old one to see how the OEM filter performed.
