I had a V10 class A for 8 years. I changed the oil every 3K regardless and did it myself. It held 6 qts and was easier than changing my Dodge Dakota(also 6 qts.) because I had so much clearance under the front. With most of the auto parts stores accepting used oil for recycling, it only cost me the oil and filter. I now have a DP that holds 19 qts and I still do it myself. It is actually easier than the V10.
