This material has a relatively high boiling point, 156° C (313°F). This temperature is well above the temperatures normally encountered in the crankcase, and consequently can be expected to remain in the crankcase considerably longer than will the ordinary solvents to be found in the majority of blending oils of this type.

This solvent will not hydrolyze nor polymerize under the conditions of heat and agitation which are encountered in the crankcase of an internal combustion engine. (Note the majority of solvents which have come under scrutiny do not possess both qualities as listed in Items 1 and 2.)

Water is soluble in this solvent even though the solvent is soluble in hydrocarbons. This very interesting property is quite useful, since FP60 is used in the fuel, the solvent will absorb any water which might be present, rendering it harmless and carrying it in solution to the combustion chamber where it is burned. (Field tests show a complete elimination of water in the fuel tank and sediment bowl upon the use of FP60)

This solvent material will dissolve cellulose esters, cellulose ethers, many natural and synthetic resins, gum formed by gasoline, diesel, and lubricating oils, and lacquers forming on pistons and cylinder walls.

Furthermore, it will reduce an aggregate of sludge into ultra fine particles by solvent action on the binder, thus rendering the sludge harmless.

LUBRICATING QUALITIES

It has been shown by the inventor that the addition of LC20 to the crankcase oil appreciably reduce the coefficient of friction. To obtain this data the inventor used the Alem extreme pressure test unit. The coefficient of friction decreases with an increase of the blend. Laboratories have checked the inventor’s data and find it to be highly accurate.

The theory which underlines the behavior is that blending oil causes a depolymerization of the molecular aggregates of the lubricating oil, in which state they are free to be absorbed by the orientation on the metallic surface. The inventor has substantiated this theory by establishing the fact that the negative heat of solution is produced upon the addition of the blending oil to the lubricating oil.

In addition to this theoretical discussion, it has been shown from many field tests that this blending oil will increase the RPM of an engine under test, while fuel feed, spark timing and load are kept constant.

Other data from field operations show conclusively that an engine is substantially free from varnish, gum, and sludge subsequent to the continued use of LC20.
