I ended up using this after I bought a used sport trac and changed the fluids and filters. You can tell a difference. The fuel injectors probably need changed. Still, love the stuff archoil makes. Think I have all their products for gasoline engines except the heavy grease which I might get.
Great product love it ,woke my old Chet right up
Seems to accelerate better and run smoother. Gives peace of mind that a high mileage car is kept clean!
I was introduced to archoil products by listening to the Bill over at Powerstrokehelp.com and all of the products have been extremely successful as advertised, I will always have archoil on hand when I need something to work,I trust in Archoil.
It seems to live up to its promise of a gentle but effective cleaner.
I have two 289 Ford 1966 cars. Both had greater response time after cleaning.
Without dynamo data it would appear to work better than most products found in auto parts stores.
