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
