"Seeing this F-350 go from a cold-blooded, rough-running basket case to a truck that ran as smooth as it did the day it left the dealership definitely made believers out of us."
"Archoil is the Real Deal"
I add it to every oil change for the piece of mind.
I used your oil additive in my Silverado with the gasoline 5.3liter AFM system. AFM damaged the valves and they have been tapping for the last 20k. Added it at 160k and it has reduced valve noise by 95%! Some days it doesn't make a single noise and when it does it is much quieter. Love this stuff. If you have a Chevy with AFM I recommend you start using Archoil immediately!! My truck is a pleasure to drive again.
Great product I’m definitely buying more in the future. I have me at hand a loner car that’s been a little neglected on oil change history so I’m trying to clean it’s internals. So with all the esters, the boron and it’s thin viscosity I got good help
Made my cold starts much smoother and has even worked on my stiction related issues much better than I was expecting. I'm signed up for auto delivery so I can use it at each oil change. Thank You for this product.
This truck was sluggish with noisy injectors. Truck has quieted down and has more power. Really pleased with product and will buy more.
