Change the oil in our E450 Winnebago Aspect in our driveway like many others. I use Mobil 1 full synthetic and change at 3000 mile intervals. I also lube the zerk fittings every other oil, change at a minimum. I have also installed a quick valve which makes the whole process easy. If you have the room the E450 is simple to change the oil. The filter is right there.
You may want to send some of your oil in for analysis. 3000 miles on Mobil 1 is a pretty short interval. Use of syn generally affords longer oil change intervals.
I agree, an oil analysis is a great way to see how your oil is performing and if your change interval is optimized. You don't have to do it at every oil change to see what's going on. I have done it twice on my 2010 V10, the last at 29k miles. The report notes engine wear by looking at metals in the oil and the oil properties to determine remaining life of the oil. Both times I had changed the oil at just under 6k miles and the report recommended going up to 8k miles because the oil was still in great shape. I use Castrol Edge synthetic, 5W/20, and Napa Gold filter.
