I bought a bottle of cheap name brand 10w-30 for the lawn mower. On the back label under "Protection that lasts" there is a list of severe service exclusions including frequent towing and excessive idling.
I don't remember seeing that on the Havoline bottle and I guess EM doesn't want to sell too much CLEAN 5000.
