No Warranty Issues — Here's Why
installed between the fuel filter and the engine intake. It only treats the fuel — it does not modify or alter any engine components. This means it cannot void your OEM engine warranty.
Like other aftermarket products (Gates hoses, Fram Filters, Castrol Oil), the ECO Fuel System enhances engine performance by Electrostatically causing fuel to burn more combustible.
Federal law addressing aftermarket products on commercial vehicles supports the use of add-on fuel treatment devices that do not modify engine components.
Aftermarket Product Rights
Federal Law Protects Your Right to Use Aftermarket Products
The Magnuson-Moss Warranty Act (15 U.S.C. § 2302) prohibits manufacturers from voiding a vehicle warranty simply because an aftermarket product was used — unless the manufacturer can prove that the aftermarket product directly caused the failure.
The ECO Fuel System is a fuel treatment device that installs between the fuel filter and the engine. It does not touch, modify, or alter any engine component. No OEM can legally void your warranty based on its use.
This is the same protection that allows fleets to use aftermarket filters, hoses, lubricants, and fuel additives without fear of losing their OEM warranty coverage.

The burden of proof is on the manufacturer — not you.
The Best Test is Done by YOU
A 15-minute test won't tell you anything — a two-week test will. We recommend installing a minimum of 5 units on your fleet and recording fuel consumption, regens, and other metrics over a few weeks without telling the drivers.
Nine times out of ten, there will be a fuel savings — many times it's considerable. And with our 90-day guarantee, you have nothing to lose.
