Abstract: This invention relates to a method of reducing abnormal combustion events in a hydrogen fueled internal combustion engine (HICE) during operation of the engine. The method includes the steps of: a) providing to the HICE a lubricating oil composition including or resulting from the admixing of: i) a base oil having a KV100 of less than or equal to 12 cSt and included at greater than 50 wt. % of the composition and comprising a Group I base oil, a Group II base oil, a Group III base oil, a Group IV base oil, or combinations thereof; ii) at least one overbased metal containing detergent with a Total Base Number (KOH/g) greater than or equal to 9 and less than or equal to 500 and included at a treat level to deliver between 100 to 5000 ppm by weight of total metal and between 0.15 wt. % to 8.0 wt.
