This disclosure relates to a lubricating oil having a lubricating oil base stock as a major component, and one or more lubricating oil additives as a minor component. The lubricating oil base stock has at least one first ester that is partially esterified, and at least one second ester that is fully esterified. The lubricating oil has a flash point from about 125 C. to about 225 C. as determined by ASTM D-93, and a kinematic viscosity (KV.sub.100) from about 1 to about 5 at 100 C. as determined by ASTM D-445. The at least one first ester and the at least one second ester are present in an amount such that, as the flash point of the lubricating oil is increased, the kinematic viscosity (KV.sub.100) of the lubricating oil is decreased or maintained. This disclosure also relates to a method for increasing flash point, while decreasing or maintaining viscosity, of a lubricating oil in an engine or other mechanical component lubricated with the lubricating oil by using the lubricating oil.

The present invention provides a lubricant composition which can be washed off cold and the use thereof for application to a metal strip as anti-corrosion, wash and/or forming lubricant. The composition is 50 to 90 wt % base fluid, 3 to 15 wt % sulfonate-based corrosion inhibitor, 1 to 20 wt % ester component, 0.5 to 3 wt % phosphorus source component or 1 to 10 wt % sulfur source component as high-pressure/anti-wear additive, 1 to 15 wt % emulsifier, 0.05 to 1 wt % carboxylic acid component, 0.05 to 1 wt % aminic and/or phenolic antioxidant, 0.5 to 5 wt % wax and/or thickener component, based in each case on the total weight of the composition. Further disclosed is a dry lubricant composition which can be washed off cold.
