Absolutely. PowerFuel Tabs and Liquids are designed for use with both gasoline and diesel fuels. Whether you’re driving a light truck or operating heavy duty equipment, our formulas support better combustion across all fuel types.

Yes. Thousands of drivers and fleets have used PowerFuel across cars, trucks, boats and buses. Beyond fuel savings, cleaner combustion means less engine wear and maintenance. Case studies consistently show improved economy and reduced emissions.

1) First, establish a baseline: log 2-3 fill-ups without using PowerFuel.

2) Then treat your fuel each time you fill up, continuing to record gallons and miles using our mileage log.

3) Many users begin to see measurable gains after 5-10 fill-ups, with improvement ranges often between 10-20% (results vary).

To measure emission changes:

* Start with a baseline emissions test (e.g., CO, HC).

* Then use PowerFuel consistently for multiple tanks.

* Retest using the same parameters and compare results. Many users report meaningful reductions in regulated pollutants.
