The present invention is directed to a lubricating oil composition, a diesel engine comprising a lubricating oil composition, and a method of lubricating a diesel engine provided with an exhaust gas recirculation system, comprising lubricating said engine with a lubricating oil composition comprising an oil of lubricating viscosity, and a polymeric N-dispersant booster.

The present invention relates to a process for the production of methacrylic acid and methacrolein by means of gas phase oxidation of isobutane in the gaseous phase at 250.degree. to 450.degree. C. on molybdenum heteropoly acid catalysts that are made up of CU.sub.a H.sub.b P.sub.c Mo.sub.d V.sub.e O.sub.f heteropoly acid compounds (I), where a=0.1 to 1, b=0 to 7.8, c=0.8 to 1.2, d=9 to 12, e=0.5 to 3, and f depends on the molar numbers a to e, and/or the heteropoly acid H.sub.8 PMo.sub.10 VO.sub.39 (II) or its anhydride PMo.sub.10 VO.sub.35 (III).

Method for making catalysts for gas phase oxidation reactions by admixing a catalytically active material comprising oxides of molybdenum, phosphorus, and vanadium with combustible natural or synthetic fibers, or with carbon fibers, forming shaped bodies from the mixture, and then calcining said shaped bodies at 100.degree. C. to 380.degree. C. in oxygen, whereby said fibers are burned out to leave channels in said shaped bodies; catalysts made by such methods; and methods for gas phase oxidation reactions using such catalysts.
