I’m an Amsoil preferred customer for many years. If they have a product that meets or exceeds specification it is what I buy. I’ve observed first hand the results of using their products and in my opinion there are none better.
Bottom Line
Yes, I would recommend this to a friend.

Will be trying this one out for the first time. If it works like all the others, it will be outstanding.
So I have had 12 of these I put one in every other fuel fill up and I see the difference with my truck. I have really notice it on my girlfriends suv who suv is 2017 and it has a big difference in it. Hers is a Stinking Chevrolet.
I can hear a noticeable reduction in valve train noise after using this additive. The engine seems to run smoother especially when used in combination with P.I Performance additive.
Bottom Line
Yes, I would recommend this to a friend.

Bought a case about 2 months ago, I fill up once a week, the engine has been smoother and definitely more power and better performance, being consistent on using it for every fill up makes the biggest difference. I’m now on 5th fill up using one per fill up and stayed back to back consistent using it and love the performance in my Lexus is250
