Your satisfaction is our top priority.  Your purchase comes with the following guarantees: 

(1) NMF reduces wear and heat to your satisfaction or money back

(2) NMF cleans your engine to your satisfaction or your money back

(3) If you use NMF in your fuel NMF cleans your fuel injectors to your satisfaction or money back

These guarantees apply to amount of NMF purchased to treat one vehicle.  For example, if you purchased a 16oz bottle of NMF to treat a vehicle, the price of that 16oz would apply to a refund.  For this reason, we encourage customers to start with a small purchase of NMF enough for one vehicle.  If you are impressed with NMF then continue to buy more.
