Review: GREAT PRODUCT - WORKS GREAT, I PUT IT IN WITH 1/42TANK LEFT DROVE IT AROUND TILL 1/4 TANK FILLED IT UP GAINED 2 MPG
Review: Fuel system additive/cleaner - I did not look at any of the inside items like the top of the pistons or the valve stems or anything like that but as far as performance, my vehicle which is a 17 suburban 1500 I got better gas mileage, and the engine certainly ran cleaner than it was. Hope some find this review helpful. I also use royal purple oil in several of my vehicles. I certainly like the brand. The product comes with an attachable fill tube, which makes getting it in the fuel tank a lot easier. Note: the deeper your fuel system inlet is the better off you’ll be so you don’t spill.
