I changed the oil and filter in my 2017 3540 for the first oil change @ 50 hours. What a pain. Drained oil from both plugs, cleaned the magnets, and replaced them. No big deal. Then the filter was a pain to remove, unscrewing it all the way with the filter wrench and ratchet. Once I got it off, it took forever to install new filter. A metal hydraulic line was touching the filter and made it very difficult to start the filter on the threads. Once finally started, I had to use the filter wrench and ratchet to screw the new filter on. Then, it took me forever to removed the filler cap. But perseverance paid off finally after prying it with 2 screwdrivers.
