- Will they damage the engine or the catalytic converter?
No. F2-21 products are totally safe. Laboratory tests and over billions of miles of real-life driving prove that fuel or engine oil treated with F2-21® is non-corrosive to all metal, rubber, and plastic engine components. On the contrary, F2-21 products will actually protect and prolong the life of your engine because they will remove deposits from combustion chambers or piston rings each time you use them. Because F2-21® products also deliver more complete combustions - and thus less unburned fuel - they will also prolong the useful life of catalytic converters.
- Does F2-21® work immediately?
Yes, benefits occur at once and get better over time.
- Should I use them regularly?
Yes. You will get the greatest benefit by using F2-21® regularly. F2-21® eeFuel™ additive should be added to the fuel every time you refuel. F2-21® eeLube™ additive should be added to your engine oil after every oil change. Both products can be used in all climates and seasons.
If you stop using F2-21®, the benefits you have been experiencing will gradually disappear.
- Can I use F2-21® products for my new car?
Yes. Engine carbon deposits begin to build up within the first 3,000 miles; therefore, it is best to use F2-21® to maintain top performance and help keep your car in "mint condition." Furthermore, F2-21® products will also boost the power and smoothness of new engines.
- What happens if I over-dose or under-dose?
If over-dose, F2-21® will not harm your engine. You will still get all the benefits of F2-21®. If under-dose, you will again not harm your engine in any way; however, you may not get all the benefits or see your benefits diminish.
- Will F2-21® Fuel Additive work with ethanol gasoline?
Yes. F2-21® eeFuel™ additive is the ideal enhancer for ethanol gasoline's major problems: less BTU, more NOx emissions, and destabilization in low temperatures. F2-21® eeFuel™ helps make up the lost BTU by delivering more powerful combustion and reducing NOx emissions by removing combustion chamber deposits and lowering combustion temperature. It can also help stabilize ethanol gasoline in cold temperatures to allow continued smooth operation. F2-21 is an ideal additive for upgrading the quality of ethanol gasoline.
- Will F2-21® Fuel Additive work with bio-diesel?
Yes. Even though bio-diesel has been promoted as a renewable and cleaner fuel, U.S. EPA studies indicate that it emits more NOx emissions (up to 10%), suffers from reduced flow-ability in cold temperature, and promotes deposits in the combustion chambers. F2-21® can help these problems by enhancing combustion and cleaning combustion chamber deposits, resulting in cooler combustion temperature and therefore reduced NOx emissions.
