Trunk Piston Oils

Delo® 1000 Marine lubricants are high-performance diesel engine oils for medium-speed trunk piston diesel engines. Delo 1000 Maine lubricants are blended with highly refined base oils and carefully selected additives. They have very good viscosity control when used in severe high-temperature service, and their great BN retention characteristics prevent corrosive wear over long periods of operation. The unique detergent and dispersant additive system provides piston cleanliness and soot handling. This results in extreme reduction of both “hot” (piston lands and grooves, piston undercrown, purifier preheaters) and “cold” (crankcase, cambox, rocker area, fuel pumps, purifier bowl) deposits. Delo 1000 Maine lubricants provide a high degree of water tolerance and have good water separation.


Taro DP Series lubricants are high-performance, medium- to high-BN, diesel engine oils for medium and high-speed trunk piston diesel engines. Taro DP Series lubricants are specially developed for use in medium-speed, trunk piston diesel engines burning residual fuels with a maximum sulphur content up to 4%. Taro 20 DP can also be used in combination with marine diesel or gas oil. Taro DP Series lubricants are blended from high-quality base oils and additives that provide an extra margin of protection against ring sticking, piston deposits and wear under the most severe operating conditions.


Delo® XL series lubricants are high-performance diesel engine oils for medium-speed trunk piston diesel engines. Delo XL series are blended with highly refined base oils and carefully selected additives. Delo XL series lubricants have very good viscosity control when used in severe high-temperature service, and the BN retention characteristics helps to promote corrosive wear over long periods of operation. The unique detergent and dispersant additive system promotes piston cleanliness as well as control of fuel contaminants. This results in extreme reduction of both “hot” (piston lands and grooves, piston undercrown, purifier preheaters) and “cold” (crankcase, cambox, rocker area, fuel pumps, purifier bowl) deposits. Delo XL series lubricants provide a high degree of water tolerance and have good water separation.
