I have owned 3 CTD's and have always done my own oil changes ... except for the last time on my 03, when I was rushed for time and since I knew the first filter change Could be a challenge. Took it to Cummins Rocky Mountain in Grand Junction, CO. It's now time for the second oil change. I bought the plastic 6 in 1 wrench and crawled under the truck to get started. Guess what, they installed an LF3894, which is the wrong filter! Does anyone know if any damage has been done?? I now have to fight that round filter off in any case. What a pain!!
