My brother used this and was telling me how much he liked it and how good it was so I bought a quart. I put 7 oz in my 6.4 Hemi and I have seen a change in gas mileage the truck only has 59 thousand miles on it so was not making noises but I do feel better with add protection

I have a 2019 nissan Frontier 4.0 and starting to get high mileage creeping up on 150k and noticed my oil pressure rising with every oil change and valves were starting to get pretty loud on cold starts! Add this with every oil change since and noticed a dramatic change, enough to where my tranny was starting to jerk so did a flush and added some prolube to it as well! Smooth sailing ever since!
