Customer Benefits

Maintains power output
The detergent/dispersant additive system provides control of high temperature deposits in areas such as the undercrown of the piston and the piston ring belt area, enabling piston rings to function efficiently. 

Prolongs oil life
Base Number (BN) level and superior alkalinity retention characteristics maintain sufficiently high BN under all service conditions to ensure corrosive acids formed by the combustion of fuel sulfur are effectively neutralized, thereby minimizing liner wear. 

Efficient purifying system performance
Excellent water separation characteristics enable water to be centrifuged out with essentially no loss of additive.


Delo® 1000 Marine is a lower alkaline reserve (12 Base Number) trunk piston engine oil (TPEO). 

Delo® 1000 Marine is designed for use in mediumspeed trunk piston engines burning distillate fuels with sulfur content up to 1.5% in marine or stationary service.

  • Medium-speed trunk piston engines in stationary power generation 
  • Medium-speed trunk piston engines (marine service)
  • Engine reduction gears
