Q:
have a 97 explorer sport with 4.0 sohc Iam looking at adding a oil treatment but there are so many. Theres seafoam, resoline, restore, plus many more. Has anyone had better results from one or the other. What the best one to use?
A:
The best one to use is none unless it needs it. If its burning oil or losing compression from age, the only one I have ever used with any success is Restore, but for the most part its all snake oil. They are often times nothing more than viscosity-altering chemicals in a petroleum base.
A:
No oil treatment is the best treatment. Just use a good oil, everything you need is already included. This is also what all engine manufacturers recommends.
