I did my first oil change (1st one done by dealer). I go the M1 113 which all sites said was the proper size for my 6.4L 2500. I compared it to the one installed by the dealer - it was much smaller - it fit but was smaller. Mobil1 Extended Performance Oil Filter M1-113: Advance Auto Parts This is the larger Mopar filter I took off my truck. Amazon says it does not fit my truck but this is what the dealer put in and I did not have any problems. https://www.amazon.com/Mopar-MOPAR-0.../dp/B01FKPJ12W If you look at the top view; you can tell that the above filter is larger - wider and longer then the M1 113. The canister and gasket on the M1 are about the same size but on the Mopar one the canister is larger then the gasket. Anyone think there will be a problem using the M1 113? I'm towing in the southwest and will be going long distances in remote areas so I'm concerned. I sent an email to the seller to confirm that the larger filter is OK and if it is I will be using it in the future.
