Hey guys,
I just emailed Travis, CA's National Part Manager down in Mesa, AZ. Really nice guy. I've gotten to know him quite well over the last 6 weeks since I purchased my rig. Extremely helpful.
He says they use a synthetic recycled oil called EcoPower in all their rental RV's. It's not too easy to get it yet. Closest place to me is 30 miles away at a Meineke Auto Care Center. It seems like Meineke is the main retail distributor right now. You can go on their website to check it out and see where it's available near you.
http://www.ecopoweroil.com/I think just going with Mobil 1 or another synthetic is the best way to go.
