Definitions

  • the present invention relates to crankcase lubricants. More particularly, it relates to universal lubricants which are effective to minimize soot related viscosity increase and thermal oxidation induced viscosity increase while preventing wear and corrosion under a variety of conditions.
  • crankcase lubricant that performs adequately in one engine at given operating conditions does not necessarily perform adequately when used in a different engine or under different conditions. While theoretically, lubricants could be designed for each possible combination of engine and service condition, such a strategy would be impracticable because many different types of engines exist and the engines are used under different conditions. Accordingly, lubricants that perform well in different types of engines and across a broad spectrum of conditions (e.g. fuel type, operating load, and temperature) are desired. Design of crankcase lubricants is further complicated in that the concentrated mixture of chemicals added to lubricating oil basestocks to impart desirable properties should perform well over a broad range of different quality basestocks. Meeting these requirements has been extremely difficult because the formulations are complicated, tests to ascertain whether a lubricant performs well are extremely expensive and time consuming, and collecting field test data is difficult since variables cannot be controlled sufficiently.
  • API CG-4 addresses the performance of heavy duty lubricants with low sulfur fuels. At the. same time fuel sulfur levels for off-highway equipment may have a higher level. Furthermore, in some geographical regions such as Latin America, fuel sulfur levels remain high for all applications. Lubricants for use in heavy duty diesel engines therefore need to perform acceptably across a range of sulfur fuel levels.
  • API American Petroleum Institute
  • manufacturers of heavy duty diesel engines periodically have required lubricants to pass additional tests before the lubricant can be approved for use with that manufacturer's engines.
  • Lubricants that meet all the certification requirements of heavy duty diesel engine manufacturers and all the requirements for the highest level of the American Petroleum Institute's oil service classifications for both gasoline fueled engines and heavy duty diesel fueled engines are often referred to as universal oils.
  • Caterpillar 1 G2 Among the many tests that heavy duty diesel lubricants have been required to pass are the Caterpillar 1 G2 and the more recent Caterpillar 1M-PC, 1K, and 1N tests. Acceptability of an oil is based on control of oil consumption and piston deposits (top groove fill, top land heavy carbon, and weighted deposits). Stuck piston rings or distress of the piston, its rings, or its liner will also disqualify an oil.
  • the Caterpillar 1N requires a low sulfur fuel (0.05 wt %) while the 1K uses a fuel with traditional sulfur levels (0.4 wt %).
  • the Mack T-7 test and its successor the Mack T-8 are part of a panel used to determine acceptability of oils for engines manufactured by Mack Truck Company.
  • the Mack T-7 (the Mack Truck Technical Services Standard Test Procedure NO. 5GT 57 entitled “Mack T-7: Diesel Engine Oil Viscosity Evaluation", dated Aug. 31 , 1984) tests soot related viscosity increase in diesel engines.
  • the Mack T-8 (the Mack Truck Technical Services Standard Test Procedure entitled “Mack T-8: Diesel Engine Oil Viscosity Evaluation”, dated October 1993) evolved because the fuel injection timing in some newer engines has been retarded to enable the engines to meet emission requirements. At the same time fuels have been reformulated to have lower sulfur content altering physical and chemical properties of the soot. Some engines designed to run on low sulfur fuel with retarded fuel injection have experienced excessively high soot related viscosity increases, excessively high filter pressure drops, and excessive sludge deposits.
  • the Mack T-8 test runs for 250 hours with an engine operating at 1 ,800 RPM with an applied load 1010 -1031 Ib.-ft (1369.4 - 1397.8 newton-meters).
  • soot levels, the differential pressure across the oil filter, and kinematic viscosity of the test fluid are measured.
  • the measured viscosities and soot levels are used to interpolate a viscosity at 3.8 wt % soot level.
  • An oil passes the test if that viscosity differs from the lowest viscosity measured in the test by 11.5 cSt or less. If two tests are run the two results when averaged must be 12.5 cSt or less. If three tests are run the three results when averaged must be less than 13 cSt. An additional requirement includes control of filter pre sure differential.
  • the Mack T-8 is much more severe than the Mack T- 7 :4 and requires a higher dispersancy level in the fluid.
  • CRC L-38 Another test required of heavy duty diesel lubricants is the CRC L-38 (ASTM D5119). That test is run on a single cylinder laboratory gasoline engine. It is designed to test a lubricant's ability to prevent corrosion of a bearing made from copper and lead, and to prevent sludge and varnish formation.

In that case the dispersant viscosity modifier serves as the nitrogenous source of TBN.
  • Viscosity modifiers are used only in multi-graded oils.
  • the amount of ashless dispersant is determined in part by the TBN requirement of the present invention and also by requirements to achieve desired dispersancy without unnecessarily increasing the cost of the finished lubricant or introducing performance debits in one or more of the many areas associated with approval of a test fluid.

Surprisingly, this shift in TBN controls soot related viscosity increase.
  • the total amount of TBN provided by nitrogen containing ashless dispersants, nitrogen containing viscosity modifiers, and oil soluble aliphatic, oxyalkyi or arylalkyi amines should be at least 1.5.

  • the lubricant is free of aromatic amines having at least two aromatic groups attached directly to the nitrogen.
  • aromatic amines especially alkylated diphenyl amines, have been found to adversely impact soot related viscosity increase.
  • Formulating the lubricant without these compounds that heretofore have been widely used for their excellent antioxidancy properties permits setting the level of TBN contributed by nitrogenous components closer to the 1.5 minimum thereby minimizing the deleterious effects associated with excessive nitrogen.
  • the lubricant should preferably have less than 0.2 wt % active ingredient of these aromatic amines having at least two aromatic groups attached directly to the nitrogen.

  • Yet another embodiment of the invention requires one or more boron containing additives whereby the lubricant contains at least 100 parts per million (ppm mass) of boron. Conveniently the lubricant contains 180 ppm (mass) boron. Boron helps control corrosion of bearings made from copper and lead.
