Heavy duty diesel having reduced amounts, for example less than 30% by weight, of Group IV and / or Group V feedstocks, and an amount of phosphorus-based antiwear agent that introduces 1200 ppm or less of phosphorus into the lubricant. (HDD) Low-viscosity SAE 0W and SAE 5W multi-grade crankcase lubricants for engines (these lubricants meet the wear performance requirements of API CJ-4, API CI-4 and / or ACEA E7 specifications) Providing a means for blending. More than about 30% by weight of Group IV feedstock and / or Group V feedstock, including at least about 0.3% by weight non-hydrogen, based on the total weight of the oil of lubricating viscosity API CJ-4, API CI, formulated with an olefinic polymer, and greater than about 40 ppm boron, having a sulfated ash content of 1.0% by weight or less, a sulfur content of 0.4% by weight or less, and a phosphorus content of 0.12% by weight or less -4 and / or SAE 0W and 5W multi-grade crankcase lubricant compositions for heavy duty diesel (HDD) engines that meet at least one performance requirement of the ACEA E7 specification.
