The first time that I used this product I was shocked at what a difference it made. I have been using it ever since. No other additive compares.
I've been using the 6200 for awhile and it's great, but I ordered the 6500 and immediately noticed an increase in fuel mileage with the first tank.
I’ve used it for only 6 months and from the beginning I noticed a big difference. I add some every time I fill my truck. About 2 weeks ago my truck turned the 400K mark and my truck never ran this good.
I use this in every diesel refuel and I have noticed better gas mileage and my engine runs smoother.
