No way on God's little blue ball the associates(ahem) at Wally World touch any vehicle I own. I personally know of 2 motors(gas) that were replaced because no oil was replaced after draining. Is it really worth trashing a high $$$ motor just to have someone else do your maintenance? It's really not that difficult and I spend the time waiting on the oil to drain checking hoses, wires, etc. It's a good time to give the bottom end a good looking over to see if anything is amiss. Do you really think the minimum wages guys are going to do that for you?
