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