Supreme LP/NG Motor Oil was engineered to effectively lubricate delivery trucks, service fleets, and urban buses that are typically powered by LP and NG fuels. There are some inherent issues and disadvantages when operating engines powered by these gases, so the first goal is to select the proper lubricant that can overcome these unique issues. Supreme LP/NG Engine Oil utilizes specially refined base stock oils that have had all detrimental components and byproducts removed so that the chance of any varnish, gum, or sludge deposits forming is minimal or none. The next step in processing these base stocks is to hydro-treat the oil, which enhances its ability to resist oxidation and also creates a base oil that allows higher quality additives to be effectively blended in. The final step in preparing these specialized base oils for use in LP and NG powered engines is to put them through a de-waxing process. This provides the oil superior flowability during cold temperature environments. All these processes put together create a high performance base oil that surpasses the standard industry specifications for LP and NG engines.
In the past, natural gas powered engines typically utilized lubricants that were formulated with naphthenic base oils, or basic conventional motor oils were used. The fact of the matter is, these types of low quality lubricants were not designed to be used in LP and NG powered engines. These conventional lubricants quickly deteriorated and caused too much deposits to form within the engine, which resulted in frequent breakdowns, leading to downtime. Supreme LP/NG Motor Oil is specially formulated specifically for the unique LP/NG environment. Its specialized low ash additive chemistry is long lasting and radically reduces piston deposits.
Supreme LP/NG Motor Oil was engineered to have a much lower ash content than other similar lubricants on the market. When looking at the top limit in the industry to be considered a low ash oil, Supreme LP/NG Engine Oil has a much lower sulfated ash value. It has a sulfated ash weight of 0.5%. Our goal with this low ash chemistry is to help in the reduction of deposits in the piston’s top land area. If a high ash oil is being used in an LP and NG engine, and the fuel has a level of hydrogen sulfide of 0.10% by volume or less, this presence of hydrogen sulfide can create unnecessary deposit buildups. This damaging deposit buildup can lead to turbo damage, combustion chamber damage, or alve damage if left to operate unchecked over prolonged usage. When utilizing higher-than necessary high ash content oils in LP and NG powered motors, you are creating an environment for damaging deposits to form which greatly reduces the life of the motor. One of the detrimental issues that have to be dealt with when using LP and NG fuels is protecting an engine against hydrogen sulfide. Hydrogen sulfide is corrosive towards any other metals such as bronze, brass, etc. Supreme LP/NG Motor Oil utilizes an exclusive proprietary additive called HSS, which its sole function is to protect the internal parts of the engine from any attacks by hydrogen sulfide. Through its unique HSS additive chemistry, engines powered by LP and natural gas are sure to be protected against any corrosive attacks.
Some LP and natural gas motors are designed utilizing electrical governor actuators. These electrical governor actuators must be precisely controlled to operate. These controls are lubricated by the engine oil. It has been found that if an engine oil utilizes VI or what is called viscosity improvers, they hinder the operation of electrical governor actuators. Supreme LP/NG Engine Oil is not formulated with viscosity index improvers, thus it is the perfect lubricating oil for engines utilizing electrical governor actuators.
Supreme LP/NG Motor Oil has been found to be an excellent lubricant for spark ignited motors. The heavy duty spark ignited engines have a special 7,000 hour test that rates an LP and NG engine oil’s ability to lubricate in these types of engines. Supreme LP/NG Motor Oil excelled during this arduous test. It showed no ring scuffing or ring sticking. Also, the liner area showed no scuffing nor any carbon cutting, which could happen if there was too much deposits in the piston land area. Beyond this, it passed the oil consumption requirements with flying colors for this test. It stayed within the test limits for valve recession, and when the test was concluded and the oil analyzed, the condition stayed absolutely within the limits for total base number, oxidation, and nitration.
Supreme LP/NG Engine Oil has a total base number (TBN) of 7.0. Comparing this TBN level to our other motor oils, 7.0 seems low. However, this oil was designed specifically for LP and NG engines. On the other hand, comparing total base numbers versus other competitor oils, their numbers are typically 5. By choosing to use Supreme LP/NG Engine Oil, with its higher total base number, your engine benefits by having the capacity to neutralize higher amounts of acids and helping to protect against the effects of these harmful acids better than if a conventional oil was used with a lower TBN specification.
Supreme LP/NG has many applications for use in LP and NG OEM manufacturer engines, including Clark, Cummins, Caterpillar, Fairbanks, Cooper-Bessmer, Stewart, Superior, Morse, Stevenson, Ingersoll-Rand (category I, II & III), and Waukesha V.H.P.
