Hello just come from the friendly PitStop people, who put a set of winter tires on my KA 60 HP BJ 2001. He claims the following: The Ford dealer, who made the last oil change, allegedly filled in the wrong oil. There is a new recommendation from Ford 0W40 to fill in. This is more expensive but more heat-resistant and the engine would be less covered up. Or vice versa: With my current oil the engine would be shed faster. What do you think d Has anyone heard anything like that or knows anything nearer? Or did Pit just want to tell me about it?……??
