Excellent product. I highly recommend it for anyone who wants to reduce fuel consumption and save some cash in return.


I was looking for ways to reduce my fuel consumption. I even took some economical driving lessons. There is where I found out about FuelGuard. One of my classmates recommended it. Bought it shortly after and I can definitely see a reduction in fuel consumption.

Oscar Fuel Saver

This product works great. I have a Chevrolet Silverado that usually does 16 miles per gallon but with this gadget, it does 21-23 miles per gallon in the highway.
