Being a Dodge/Cummins owner I frequent the TDR website. Here is something that I learned from that site that I now use on my lawn equipment as well (Lazer Z)... When changing the oil filter try the following: 1. Loosen the filter with a wrench/hands 2. Before removing slip a ziplock style baggy over the oil filter so it completly covers it 3. Spin off the filter and then close the ziplock baggy 4. All oil is contained in the baggy and usually none spills. Just used this on my Lazer Z and worked flawlessly. No oil anywhere. Hope that helps!
