YES! When we are taveling we get the oil changed at WalMart... I look until I find one with the high bay and a pit, that makes it easy... they heve the same oil and filters that I get at the dealers
The dealers charge $86, while they are in the back room , out of sight I've had them wipe off the old filter, pretend it's new (I matk the filter), and they usually find some thing that needs attention for a lot of additional money...
Walmarts charge $44 total for the oil, filter, and labor and I can stand outside the rope and watch them do the work... I usually have them drain the oil from the campers built in generator too (and I tip the mechanoc since WalMart doesnt have generator service button on their registers). Walmart has the correct oil filter for the generator too,
I like honesty... I find WalMart and Sams are honest... like them or not. I buy tires from Sams.
