Jeep Grand Cherokee 3.0 CRD.
I ended up establishing an account with Amsoil and went with the European Car 5w40 formula that was posted earlier. I had a rather extensive discussion with Amsoil on the product which led me to setting up the account and then I had the case on my front porch 2 days later which was nice.
Also.....Amsoil is a distributor for Mann filters and they charged me $9.95 for the oil filter.....the local jeep dealer charged me $45. Anyways...when the Mann filter showed up last night I thought it looked very familiar so I opened up the OEM filter which came in a Mercedes box and what do you know......virtually identical even down to the part number. The only difference is that the OEM has a small Mercedes symbol stenciled on it
I'll post pix tomorrow but for anyone with a CRD....forget the dealer on the filters.
