MOLY PRO-SPEC^® Motor Oil

HIGH LEVEL OF MOLY INCREASES FUEL ECONOMY REDUCES WEAR, FRICTION AND HEAT REDUCES OIL CONSUMPTION HIGH TBN USES SUPER-FINE MOLY PARTICLES

The MoS2 platelets are capable of supporting up to 500,000 psi at the same time they offer little resistance to shear forces which tend to slide the platelets over one another thus reducing friction and wear.

Under boundary lubricating conditions, the mating surfaces are not held apart and metal-to-metal contact occurs. The result is a scuffed or galled surface. Such a situation can be avoided by using a lubricant with added molybdenum disulfide . . . Texas Refinery Corp. MOLY PRO-SPEC^® MOTOR OIL.

Molybdenum disulfide - - called moly - - works because its chemical structure has platelets which slide past each other easily. To compare this to a lubricating oil that has a coefficient of friction in the range of 0.15 to 0.2, Moly has a coefficient of friction in the range of 0.03 to 0.06. Texas Refinery's MOLY PRO-SPEC^® MOTOR OIL contains a high concentration of moly, which accounts for its low coefficient of friction, providing the good boundary lubrication needed to produce the beneficial points to be discussed. 

Several tests were conducted on fuel consumption including test stand engines, leased fleets, and buses. The overall average fuel economy improved 4.4% with a range of 2.3 to 6.4 percent being noted. For the buses and leased fleets, a fuel economy improvement of up to 6.6 percent was obtained. In track test work, fuel economy improvements up to 7.9 percent were obtained.

Texas Refinery Corp. has years and years of field-proven experience with MOLY PRO-SPEC^® MOTOR OIL. Most companies, if they have a molybdenum disulfide motor oil, have only been selling it the last few years. Just remember, molybdenum disulfide looks a little like graphite and yet it is twice as slippery as graphite. MoS₂ can carry loads up to 500,000 psi with a thin film of moly plated out on the metal surfaces. Once moly adheres to the metal, the only way to remove it is by grinding or wearing it off over a period of time. You will also be interested to know the maximum buildup of molybdenum disulfide is .0002 of an inch - - - not enough to affect bearing clearances - - - just enough to help prevent metal to metal contact. Since it's replenishing the moly film, wear, friction and heat are continually reduced.

Oil consumption can be a costly problem with engines. This motor oil fights oil consumption with superior anti-wear additives. As piston rings in new engines go through the seating process, oil consumption decreases. Once the rings are sealed, itminimizes wear and extends the life of the engine. The addition of MOLY PRO-SPEC^® MOTOR OIL to older engine crankcases will reduce the wear rate too, resulting in longer engine life and does not thin out at high temperatures as do many commercial brand oils.

Has a high Total Base Number of 15 Plus. This high TBN level indicates how well it fights acids and their corrosive effects. Many commercial lubricants on the market have a TBN level from only 6 to 10.

There are many different ways to boost the TBN number of an oil. Texas Refinery Corp.'s MOLY PRO-SPEC^® MOTOR OILS receive most of their alkalinity from the detergent value of the oil. Of course, this is the most expensive way to go and it is certainly the most effective as well. High detergency TBN additives are more effective at controlling the overall effects of increased soot loading of the oil. Some of the newer fuel formulas with greatly decreased sulfur percentages have created problems, particularly in the roller cams. The high detergency helps keep this area clean. The high Total Base Number and high detergency's end results are longer life and extended drain intervals.

Texas Refinery Corp. uses extremely small particles of molybdenum disulfide for fluid products like MOLY PRO-SPEC^® MOTOR OIL. This is a much smaller particle than the one used in grease. The moly is dispersed in the fluid with special suspension agents. Since the particles are less than .33 microns, they are small enough not to precipitate out of suspension and they flow freely through filter materials.

Moly is a blackish gray color and when added to the oil to make MOLY PRO-SPEC^® MOTOR OIL, the color of the finished oil is blackish gray.
