The 3.0VM diesel takes 8qts so you need to buy 3 packs of 6qts for 2 oil changes
. Pennzoil Ultra Euro L 5W30 is spec'd for our motor.
Normal useage oil change max, according to the book, is 10k.
I did my first change at 6500 then I did a UOA (Blackstone Labs) on my 2nd change at 8500 (total 15k)and they said it looked good!
Not willing to run it up to 10k though, as we tow a TT and me being totally anal and all LOL!
