Oil Life Extension
NMF extends the life of any conventional or synthetic lubricant.  

For example, in a semi truck using conventional oil, the change interval can be extended to 40,000 miles/64,374 km -- just change the oil filter at 15,000 miles/24,140 km and 30,000 miles/48,240 km, top off the oil as necessary, and add 1 oz NMF per quart of oil topped off.   

Fuel Savings or Money Back Guarantee (semi trucks)
With NMF, fuel efficiency will normally rise. Some truckers report receiving even a mile more per gallon.  For a fully-treated (engine, fuel, transmission, differentials, hubs, power steering, greased joints) semi truck, we offer money back if fuel efficiency does not rise.  This guarantee does not apply to non semi trucks.  Treatment to qualify for the money-back guarantee is as below.  Quantity of NMF required depends on the number of axles.

Engine: 1 oz per quart of oil / 30 ml NMF per liter 
Transmission: 16 oz / 480 ml
Differentials (each one): 12 oz / 360 ml
Each Front Hub: 1 oz / 30 ml 
Power steering: 1 oz / 30 ml 
5th Wheel Grease: 1 oz / 30 ml 

With the above treatment, fuel efficiency should begin improving.  Maximum efficiency will come after NMF has cleaned the engine and fresh oil/NMF have been added.  

Drive your truck.  
Within 1000 miles, your engine will be clean.  You can change your oil at 1000 miles or wait until the normal oil change interval.  Either way is fine.  

(When you do change your oil, you will notice that it is dirtier than normal.  This is because NMF has cleaned the engine.)

Add fresh oil and NMF at the rate of 1 oz per quart of engine oil.  Your truck should now be clean and ready for an evaluation of fuel efficiency improvement.  

After driving 15,000 miles/24,140 km, compare your new fuel efficiency with the previous 15,000 miles/24,140 km without NMF.  If it isn't improved, GoNMF will refund your purchase price (offer details)

Risk-free Trial
