I may be able to answer this question myself later but meanwhile am curious .. Both times I have changed the Oil and Oil Filter on my Honda CMX1100 DCT after the Dealership Serviced the Oil Filter was a Bear to get loose both times the 2nd time was not even 2 weeks old when did it .. At age 73 am aware not quite as strong as I once was but called my neighbor and he is a recently retired Gunny Sergeant in the Marines in late 40's, Stronger than a Bear and it took near all he had to break it loose but we definitely made sure a good Oil Seal was made on the Filter this time only tightening hand tight and sealed fine.. Will find out for sure if the Dealer is not putting any oil on the seal or are they just wrench tightening it way too much .. Just wondering if anyone doing all their own Oil changes having any problem ...
