Does anyone really know if the factory uses “Honda branded oil”? Why don’t you ask the dealer what brand oil they use? If you don’t trust them to tell the truth then I certainly wouldn’t let them touch my vehicle. Also, hate to break this to you but they probably won’t change the oil filter on the first oil change. You ‘ll be able to tell if the filter was changed by whether or not the truck drips oil for a few days after service!
