Fuels, hydraulic fluids and lubricants made of or comprising a portion of renewable hydrocarbon raw materials, as well as biodegradable fuels, hydraulic fluids and lubricants are known to support microbial growth. Highly toxicorganic biocides have been added to reduce microbial growth. The use of such biocides can now be avoided, by instead using a stable solution of boric acid in a solvent, the boric acid being completely dissolved or at least free from any particles larger than 100 nm in size, and adding this solution to the fuel, hydraulic fluid or lubricant to give a final concentration of boron in the range of 1-100 ppm, preferably 1-50 ppm in the product. While preventing microbial growth, the addition of boron also reduces corrosion, in particular microbiologically induced corrosion (MIC).

Methods for preventing microbial growth and microbiologically influenced corrosion in a biodegradable and/or renewable fuel, hydraulic fluid and/or lubricant

A synthetic ester-containing lubricant with good soot-handling and, with friction modifier, viscosity modifier and antioxidant present, improved engine performance and cleanliness.

Lubricating compositions

Crankcase lubricant compositions for use in automobile or truck engines comprise a major amount of a lubricating oil, added copper present in oil-soluble form, at least 2 ppm of molybdenum present in oil-soluble form, and a total of from 0.05 to 2 mass % of one or more oil-soluble aromatic amines. The specified additives provide a highly effective antioxidant system.
