Doing the first oil change on my 21 1500 and couldn't get the oil filter (Mobil-1 113A) to thread on. Tried for like 10 mins and was like WTH. Then looked at the OEM filter it has a 22mm opening and the 113A I had was a 20mm opening. Go back to store, pick up a 113A off the shelf and it has a 22mm. So I have 2 113A filters, same label, same box, same stamping on the bottom, yet one has a 20mm opening and the other is 22mm. Had no problem putting the 22mm 113A on. Just something to check before I you start I guess. I've always done my own oil changes and it 25+ years have never had this issue.
The 20mm filter is "dirty" from messing with it for 10 mins or so trying to get it on.
