Magnuson-Moss Warranty Act
Understanding the Magnuson-Moss Warranty Act:
- The Magnuson-Moss Warranty Act, a federal law, protects consumers from being unfairly denied warranty coverage by manufacturers.
- It stipulates that the use of aftermarket parts or treatments cannot void a vehicle warranty unless it can be conclusively proven that the part or treatment caused damage.
DF5 and Engine Manufacturer Warranties:
Cummins, Detroit Diesel, and Caterpillar:
These manufacturers set specific standards for fuel treatments. Our extensive testing and compliance with industry standards ensure that DF5 meets or exceeds these requirements.
No Impact on Warranty Coverage:
- The use of DF5 in engines from these manufacturers does not void warranties. The treatment’s properties align with the fuel specifications outlined by these engine makers, ensuring safe and effective use.
