Abstract: A lubricant composition of a synthetic oil of lubricating viscosity, 3 to 6 percent by weight of a nitrogen-containing dispersant, 1 to 2.5 weight percent of an overbased magnesium detergent, 1 to 5 weight percent of an antioxidant; and 0.25 to 1.5 weight percent of a friction modifier is useful for lubricating a hydrogen-fueled engine. The composition will typically contain less than 0.01 weight percent Ca, less than 0.01 weight percent Zn, less than 0.06 weight percent P, and will have a sulfated ash level of less than 1.2%.
