The presence of a minor amount of certain quaternary ammonium hydroxides in an engine lubricating oil has been found to be effective in reducing and controlling combustion chamber deposits and octane requirement increase in spark ignition internal combustion engines and in reducing oil consumption in diesel engines.

The present invention resides in a turbo oil composition exhibiting enhanced antioxidancy and resistance to deposit formation, and to a method for achieving that result in turbo oils. The gas turbine lubricating oil of the present invention comprises a major proportion of synthetic polyol ester based base stock including diesters and polyol esters, preferably polyol ester based base stock and a minor proportion of an antioxidant/deposit control additive, specifically a sulfur-containing carboxylic acid (SCCA) derivative. Other conventional additives such as extreme pressure, pour point reduction, oxidative stability, anti-foaming, hydrolytic stability, improved viscosity index performance, anti-wear, and corrosion inhibitor additives and others may also be employed. The use of SCCA derivative produces a turbo oil exhibiting markedly superior oxidation stability and deposit control performance compared to that exhibited by turbo oil without the SCCA derivative.

A lubricating oil composition having improved antiwear and fuel economy properties which comprises a lubricating oil basestock and an alkoxylated amine salt of a dihydrocarbyldithiobenzoic acid of the formula ##STR1## where R. sup. 1 is a hydrocarbyl group having from 2 to 22 carbon atoms, R. sup. 2, R. sup. 3, R. sup. 4, R. sup. 5 and R. sup. 6 are each independently hydrogen, a hydrocarbyl group containing from 1 to 24 carbon atoms or a hydroxy group with the proviso that at least one of R. sup. 2 to R. sup. 5 is a hydrocarbyl group, and x and y are each independently integers of from 1 to 15 with the proviso that the sum of x+y is from 2 to 20.

It now has been discovered that lubricating compositions containing (disulfido) tris (N, N-substituted dithiocarbamato) Mo(V) compounds can be enhanced by the inclusion in the composition certain polydentate ligands. Thus, the present invention comprises a major amount of an oil of lubricating viscosity and a minor, but effective, amount of an antiwear and friction reducing additive consisting essentially of (disulfido) tris (N, N-substituted dithiocarbamato) molybdenum (V) compounds and polydentate ligands and mixtures thereof.

A composition of matter having utility in lubricant formulations, said composition being the reaction product of adenine, alkoxylated amine and dihydrocarbyldithiophosphoric acid and having the general formula (I): ##STR1## where R is hydrogen or a hydrocarbyl group of from 1 to 20 carbon atoms, R. sup. 1 is a hydrocarbyl group of 2 to 22 carbon atoms, R. sup. 2 and R. sup. 3 are each independently hydrocarbyl groups having from 3 to 30 carbon atoms, x and y are each independently integers of from 1 to 15 with the proviso that the sum of x+y is from 2 to 20, and a, b and c are independent numbers from 1. 0 to 3. 0 wherein the ratios between a:b, a:c and b:c range from 1. 0:3. 0 to 3. 0:1.

This invention relates to synthetic based turbo oils, preferably polyol ester-based turbo oils which exhibit exceptional load-carrying capacity by use of a synergistic combination of sulfur (S)-based and phosphorous (P)-based load additives. The S-containing additive of the present invention is sulfurized fatty acid (SFA), preferably the sulfurized oleic acid (SOA) and the P-containing additive is one or more amine phosphate(s). The turbo oil composition consisting of the dual P/S additives of the present invention achieves an excellent load-carrying capacity, which is better than or equivalent to that obtained when each additive was used alone at a treat rate higher than the total additive combination treat rate, and this lower additive concentration requirement allows the turbo oil composition to meet or exceed U. S. Navy MIL-L-23699 requirements including Oxidation and Corrosion Stability and Si seal compatibility.

This invention relates to synthetic based turbo oils, preferably polyol ester-based turbo oils which exhibit exceptional load-carrying capacity by use of a synergistic combination of sulfur (S)-based and phosphorous (P)-based load additives. The S-containing additives of the present invention are thiosemicarbazide and its derivative, and the P-containing component is one or more amine phosphates. The turbo oil composition consisting of the dual P/S additives of the present invention achieves an excellent load-carrying capacity, which is better than that obtained when each additive was used alone at a treat rate higher than or comparable to the total combination additive treat rate, and the lower concentration requirement of the P-based additive allows the turbo oil composition to meet U. S. Navy MIL-L-23699 requirement on the Si seal compatibility.

A method and apparatus for measuring particulates contained in the exhaust gases from internal combustion engines which dilutes the exhaust gases with prefiltered and precooled air to produce a constant volume mixture which may be sampled for exhaust gas emissions as well as for particulates. After mixing of the exhaust gases and the pretreated air, sampling of the mixture by isokinetic probes produces a uniform sample of particulate matter which is collected on temperature controlled filters for analysis.
