Lubricants – Engine Oil:

SAE 40 – Motor Oil

Application of Use:

  1. Neptune Motor Oil SAE 40 is a heavy duty monograde engine oil specifically formulated for heavy duty diesel engines (Diesel) operating in both on- and off-highway service. These low ash engines have special lubricating needs, which no ordinary diesel crankcase engine oil could satisfy.
  2. Neptune Motor Oil SAE 40 is formulated with proven solvent refined base stocks and a carefully balanced system of detergents, inhibitors and anti-wear additives.
  3. Medium speed industrial or marine propulsion and auxiliary engines burning residual fuel oils with Sulphur contents up to 3.5%
  4. Marine engine reduction gears and certain other ship-board applications, where specialist lubricants are not required.

Performance Features:

  1. Engine cleanliness
  2. Thermal stability and resistance to oxidation
  3. Rapid neutralization of acidic combustion products

Performance Benefits:

  1. High Temperature Deposit Control
    Helps to protect against high temperature oxidation and oil thickening in older engines.
  2. Special Extreme Pressure Anti-Wear Properties
    Good control of deposits and wear optimize the engine overhaul intervals.
  3. Protection Against Rust, Corrosion, Varnish & Sludge
    Helps keep oil screens, filters, and rings clean and free for prolonged periods.
