For satisfactory operation of a gasoline engine (without engine knock) it is important to use a gasoline with the Octane rating for which the engine has been designed. As the new engine accumulates mileage, combustion chamber deposits (CCD) are formed and they continue to increase until they reach equilibrium after 10,000 to 15,000 miles. The CCDs result in an increase in the octane number required (ONR) for the satisfactory operation of the engine. For a typical gasoline engine, the increase in ONR can range from 4 to 8 octane numbers.
Vehicle manufacturers compensate for this increase in ONR by detuning their new engines for lower octane gasoline so that after 10,000 to 15,000 miles when the ONR is stabilized, the vehicle may run satisfactorily using the commercial gasoline available in the market place. If FullON™-DurAlt® is consistently in the marketplace fuels, the ONR can be minimized. In that case, new vehicles can be tuned by the manufacturers to perform at lower octane resulting in up to 5 percent better fuel economy.
REDUCING THE ONR
FullON™-DurAlt® improves the combustion process and therefore minimizes the build up of CCDs in gasoline engines which increase ONR. Tests conducted at independent laboratories have shown that FullON™-DurAlt® reduces ONR between 55 to 80 percent or by 3 to 5 octane numbers.
GRADES OF GASOLINE
FullON™-DurAlt® works in all grades of gasoline from regular to premium reducing the ONR by up to 5 points.
NEW AND USED VEHICLES
In new vehicle engines, FullON™-DurAlt® minimizes the formation of CCDs and reduces ONR. The engine stays cleaner, runs better, requires less maintenance, gives better fuel economy and produces lower emissions.
In used vehicle engines, FullON™-DurAlt® will give instant noticeable benefits through improved combustion of the gasoline or diesel fuel. Used engines that are running roughly will have a noticeable smooth out effect when DurAlt® is added to the fuel. Additional cost benefits can be obtained by enabling the engine to obtain peak performance with reduced premium fuels in both gasoline and diesel.
Modern gasoline powered vehicles are equipped with knock sensors. When these engines operate at borderline knock conditions, the knock sensor recognizes it and retards the spark timing to avoid engine knock. However, retarded spark timing has adverse effects on engine performance and fuel economy. When FullON™-DurAlt® is used in gasoline, it immediately reduces the ONR, and the knock sensor advances the spark timing resulting in significant improvements in engine performance, fuel economy, and emissions.
