I have used Marvel products and it did most of what it touted. BUT, when I ran out of Marvel and the only upper engine lube available was Lucas. I bought it because I know how important upper cylinder and valve train lubrication really is.
The Lucas product performed superbly.
My engine was extremely quiet and no loss of power and definely a measurable increase in gas mileage.
This is the product you would need to use before you trade in your vehicle. No lifter noise, whatsoever. I have 135,000 ,miles on my Dodge 4.7 and I’ll bet you can’t tell it from new.
Give a try, It only does what it says!
