So no one would have to wade through 3 pages on the previous thread...
I changed the oil. It took 18 quarts; 16 of oil and 2 of Lucas oil treatment. I inflated the coach's air bags and had enough room to work. I used a Rubbermaid 30 quart storage box to drain into. It slid right under. I used Mobil Delvav 15w40 diesel oil. The spout is great because it telescopes out to form a tight seal against the filler neck. I could squeeze the bottle to empty it quickly and there was very little spillage. I used an old rubbermaid pitcher and funnel to get the used oil from the pan back into the oil jugs for disposal. It took about 2 hours
Tah Dah!!
