I am a new GrandCherokee diesel owner, although I have Ford,VW,Chevy diesels. Not sure how this forum works, so hope you get this message.
In terms of oil filter, Purolator has a L25646 that is supposed to be the same as the HU821. It is $30.09 at PepBoys.
A place called Atlantic Imported Auto Supply

says they sell the HU821X for $10.23 each or $55.25 for a six pack. I have not bought any yet.
Regarding oil, I use Mobil1. TurboDieselTruck 5-40W is the retail packaging, Delvac1 is the commercial packaging, but they are the same product. The TurboDieselTruck is generally cheaper even though the Delvac1 is available in 55gal drums. UPS uses Delvac1 exclusively in their fleet.
I am interested in any experience/information regarding the Jeep diesel.
