Well, I was just asking if anybody had used either of those products. The Valvoline fuel system cleaner is the same sort of product as Chevron Techron or Gummout Regane. It is just a fuel system cleaner. People use fuel system cleaner like that all the time, at least in the USA. How does it compare with others?
The Valvoline engine flush is a nonsolvent engine flush. It is made by Valvoline-a major oil company.
