When it comes to buying oil, my father is obsessed with doing a lot of research so he is certain that his engines can handle the type of oil that he uses with them. He has engines in his cars, boats, and ATVs that use entirely different types of oil. There are certain brands that he trusts more than others, just because he knows the brand and has used it for a long time.
He always uses the same oil for his car as the oil that was first recommended to him by the car dealership. When it comes to his boats and his ATVs, he is careful to use Yamalube 2 cycle oil that can meet the requirements of these different engines. He always takes great care of all of the engines that he has by making sure to get them oil that he trusts.
