ProTecta Synthetic Fuel System Treatment: Technical Overview
Performance is testing conducted by major oil companies leads us to
believe that the next generation of additives will be those that work
with or re-fortify the engine oil. This can be addressed on two fronts -
fortifying the engine oil as SFR has engaged in for over 15 years, or
considering fuel additives as "daily vitamins" for the engine
oil. This gives us a new and challenging technical area for improving
the performance and durability of modern automobile engines.
The piston and ring area is mostly a "boundary lubrication" area, where the oil film is very thin and the microscopic "high spots" of metal parts come into contact with other metal parts. The resulting friction in such areas is a major reason for inefficiencies that contribute to fuel consumption.
The design of the modern gasoline engine provides great opportunity for a fuel additive to assist the engine oil and function as a friction reducer. By introducing ProTectaŽ Fuel System Treatment into the fuel, it is delivered to the cylinder wall. This area of the engine will see the greatest improvement and the benefit is almost immediate.
The piston rings and cylinder wall regions are only marginally serviced by crankcase engine oil. The piston skirts and lower ring are sometimes targeted with an oil spray but often only receive splash lubrication from the crankcase. Engine manufacturers are also keeping the cylinder walls drier to prevent oil consumption, further reducing the lubrication in this area of high friction. To increase fuel economy based on the all out push by our government, engine manufacturers are forcing oil formulations to much lower viscosities. For example, reducing the viscosities from SAE 10W-40 to SAE 5W-30. With such thinner oils, and with engines operating at higher temperatures, oil film thickness is reduced and thus there is a greater chance for metal-to-metal contact to occur.
SFR's ProTectaŽ Fuel System Treatment enters into the oil sump via the piston rings, it can further assist in reducing friction in other parts of the engine as well. Based on the additive's ability to reduce internal friction, the benefits for the consumer can include improved fuel economy and reduced wear. By using the SFR ProTectaŽ Engine Treatment along with the SFR ProTectaŽ Fuel System Treatment one can maximize results.
For those that wonder how a fuel additive can enter the engine oil, this phenomenon of additive entry into the oil has persisted throughout the development of fuel intake system deposit control additive, from the carburetor through fuel injection, intake valves and combustion chambers. To improve combustion efficiency, today's engines create a "swirl" effect, which mixes the intake charge. However, but because fuel additives do not tend to change direction as quickly as gasoline, the additives still impinge on the cylinder wall, where a thin layer of engine oil provides a convenient and safe landing spot. After a swipe from the piston rings, the additives are transported into the crankcase oil. Research has shown that approximately 25% of fuel additive put into gasoline finds its way into the crankcase oil.
The effects of fuel additives on oil performance have ranged from harmful to doing nothing, and today have even been found to be beneficial. While the public usually attributes engine oil performance solely to the oil put directly into the crankcase, it is possible to isolate the effects of fuel additives that make their way into the engine oil. SFR has been a leader in oil fortifiers for many years and now takes another step in reducing friction through a fuel system treatment.
In addition to fortifying the engine oil to improve mileage SFR has developed a synthetic fuel system cleaner found in ProTectaŽ Fuel System Treatment to keep components working like new. This powerful fuel cleaner is designed to provide:
ProTecta Synthetic Fuel System Treatment: ASTM Sequence VI Test
The "Sequence VI test" (a fuel economy test previously
used in the lubricant industry) was modified to compare the economy of
two different fuels - one with fuel additive and the other without. The
tests revealed that the improvement in fuel economy from using the fuel
additive was equal to that obtained by blending the ProTectaŽ Fuel
System Treatment friction reducers into engine oil formulations.
This Sequence VI engine testing demonstrates the ProTectaŽ Fuel System Treatment concept. The results of the Sequence VI test show that ProTectaŽ Fuel System Treatment is effective in improving fuel economy. The immediate results show that the ProTectaŽ Fuel System Treatment is delivered in a very effective manner to an area of the engine, the rings and cylinder walls, that contribute a great deal of the internal friction in the engine. The aged results show that the ProTectaŽ Fuel System Treatment accumulated in the crankcase oil and provided additional benefits. This particular test is also a good indication that ProTectaŽ Fuel System Treatment will deliver good results in modern engines and new engines as most of the Sequence VI tests begin with a freshly rebuilt motor.
This graph shows the results of three passenger cars motor oil formulations PCMO1 and one with SFR's ProTectaŽ Fuel System Treatment.
ProTecta Synthetic Fuel System Treatment: No Harm Testing
|NO HARM TESTING
Although our extensive testing has shown that the new fuel additive chemistry in ProTectaŽ Fuel System Treatment can provide improved fuel economy as it gets into the engine oil, it is also important to know that this is accomplished without harming the engine. SFR ProtectaŽ Fuel System Treatment has passed a number of rigorous no harm tests and has demonstrated that its chemical integrity is maintained.
