A lubricant formulation which is effective to remove or prevent carbon deposits in internal combustion engines has a solvency as defined by aniline point from about 20 to about 115, a volatility (as measured by NOACK) of less than 15%, an oxidative stability (as measured by PDSC) of above 40 minutes and a base oil viscosity of above 2 and below 10 cSt. The lubricant formulation can be formed from a blend of Group III, IV and V lubricants, in particularly polyalphaolefins, alkylated naphthalenes and polar Group V base stocks such as polyol esters. The carbon deposits can be removed from the engine piston by simply running the engine with the lubricant for one required cycle, or can be used continuously in the engine to prevent buildup.

Sulfur-free, ashless, and low phosphorus-containing lubricant compositions for use as engine oil having improved oxidation stability. The lubricant composition can include about 60.0 mass % to about 99.8 mass % of an oil base stock, at least one ashless antiwear additive, at least one ashless detergent, and at least one antioxidant, based on a total mass of the lubricant composition. The oil base stock can include at least one polyalphaolefin and at least one alkyl naphthalene. The lubricant composition can contain less than about 0.05 mass % phosphorus, less than about 0.05 mass % sulfur, and less than about 0.05 mass % ash. The lubricant composition can be made by a process that includes combining the above-mentioned components to provide a lubricant composition.

A non-water-based tire lubricant includes a thickening agent and a thinning agent. The thickening agent may be a silicone grease, hydrotreated light petroleum distillates, or hydrogenated liquid rosin ester, and the thinning agent may be a blend of petroleum distillates and additives or a silicone liquid. The tire lubricant has a pliable consistency, is easier to apply and use than standard tire lubricants, allows the tire to seal at much lower pressures, and is not water-based so that nitrogen concentrations inside the tire are maintained at 100 percent.
