I haven't used it enough to really tell.

I bought this product because it said it would limit friction and increase my fuel mileage...... When I started using it I was getting 5.5 MPG I am currently after using it getting 5.5 MPG I feel that if given time it may increase but if you need this review immediately this is what it is. and yes if it works I would recommend this product to anybody if it doesn't work I'm going to do just the opposite but it's too early to tell but I'm not going to get five stars not knowing if it even works or not so I went in the middle

Custom tune on a 60

Custom tune on a 60 series 12.7 Detroit BK model. 575 horsepower 1850 torque. I use Mystic semi-synthetic oil. I needed a good product to lubricate fuel nozzles. My motor produces more heat now so I use your products to keep my motor in check. Thank you for the products they work well for me. I will be ordering more
