RF6326 and RF6327 refers to a group of high performance marine medium speed trunk piston diesel engine oil packages, which is composed of detergent, dispersant, ZDDP and etc. Of which RF6326 serves as core package and RF6327 serves as high performance BN booster, the marine medium speed trunk piston diesel engine oil formulated with a combination of both packages provide excellent acid neutralization, detergency, dispersancy, anti-oxidation, anti-corrosion and water separation performance. Blending with Group I and II base oils and with the combination of RF6326 and RF6327 is able to formulate Medium-speed trunk piston engine oil, meeting GB/T38049-2019 specification with BN ranges from 12-50mgKOH/g and viscosity covers SAE30 and SAE40.
