20110111997 | AMINIC ANTIOXIDANTS TO MINIMIZE TURBO SLUDGE - A turbo-charged, sump-lubricated internal combustion engine which is susceptible to contamination of lubricant with liquid fuel, is lubricated with a lubricant which contains an amount of an aminic antioxidant, optionally in the absence of a phenolic antioxidant, thereby reducing the deterioration of said lubricant and formation of turbo sludge. | 05-12-2011 |
20110118157 | RUST INHIBITORS TO MINIMIZE TURBO SLUDGE - A turbo-charged, sump-lubricated internal combustion engine which is susceptible to contamination of lubricant with liquid fuel, may be lubricated with a lubricant which contains an amount of a rust inhibitor effective to reduce the deterioration of said lubricant and turbo sludge formation. | 05-19-2011 |
20110160108 | ALKALI METAL SALTS TO MINIMIZE TURBO SLUDGE - Turbo sludge formation is Improved in a turbo-charged, sump-lubricated internal combustion engine which is susceptible to contamination of lubricant with liquid fuel by providing said engine with a lubricant which contains an amount of an oil-soluble alkali metal salt effective to reduce the deterioration of said lubricant and said fuel contaminant. | 06-30-2011 |
20130263807 | Lubricating Oil Composition with Anti-Mist Additive - A lubricating composition containing an oil of lubricating viscosity, a high molecular weight polyolefin that is at least substantially free of ethylene-derived monomer units, and an overbased metal containing detergent, is capable of reducing intake valve deposits in a direct injection engine. | 10-10-2013 |
