Great product!

From the first 15 miles of driving, I noticed a significant change in engine behavior. Smoother acceleration, less push on the pedal to get moving, and man, is the engine running quieter! as for fuel savings I am pretty sure this will help!

PS: how often am I supposed to be using this product?

The GT/DT fuel additive/treatment is designed to work like other fuel additives, it is added to the fuel each time the tank is filled. 1 oz per 10-15 gallons of fuel. Works in either gasoline or diesel. It lubricates everywhere the fuel travels - fuel pump, fuel injectors, and combustion chamber. We have a few customers who use the fuel treatment every third time they fill the tank.

Gas Treatment

So far I can't anything has changed. I'm hoping for even a slight increase in MPG. I'm only on my first treatment, 1 of 4 vehicles.

Thanks for your purchase. MPG is highly dependent on driving conditions. The most common response we get is the engine runs smoother and I have more power. Depending on how one uses the extra power, it might result in better MPG.
