Market Applications
Primarily used in medium-speed trunk piston engines equipped with active purification systems and burning residual fuels to high sulfur contents in marine and stationary service. May also be used as a cylinder lubricant, either for trunk-type piston engines with separate lubricators, or for crosshead- type engines where oils of 20TBN, 30TBN.40TBN are recommended by the manufacturer.
Performance Levels
Meets API Service Category CD, CE and passes the MWM-B high temperature with deposits requirement at the level of the former CCMC Sequence D-2, conforms the requirements of all major marine manufacturers who specify 20, 30, 40 TBN TPEOS.
Product Description
Highly alkaline. 20, 30, 40 Base Number trunk piston engine oil (TPEO) for use, principally in medium-speed marine-type trunk piston engines burning residual fuels to sulfur content.
