NP Super Duty 2T 40

Overview

NP Super Duty 2T 40 is a high quality, low-medium ash lubricant, designed to meet the lubrication needs of naturally aspirated and turbo-charged two-stroke diesel engines. The use of NP Super Duty 2T 40 will reduce the occurrence of exhaust valve distress.

It meets the performance requirements of Detroit Diesel Type 1 and Type 2 lubricants for two-cycle lubrication as specified by DDC Publication 7SE270 0102, "Lubricating Oils, Filters, and Fuels".

NP Super Duty 2T oils are formulated from premium quality hydro-treated base stocks and a balanced additive package resulting in good film strength and high load carrying ability. Super Duty 2T 40 provide for enhanced:

  • Detergency and Dispersancy
  • Cylinder and Piston ring wear performance 
  • Corrosion and Rust Protection
  • Oxidation Stability
  • Deposit Control
  • Thermal Stability

PERFORMANCE SPECIFICATIONS

The NP Super Duty 2T 40 meets or exceeds the test requirements of:

  • API CF-2, CF
  • Detroit Diesel 6V92TA

Benefits

The use of NP Super Duty 2T 40 would result in:

  • Protection against bearing failure
  • Low piston-zone deposits and ring-stick prevention 
  • Reduced wear of valve train and engine components
  • Reduced port plugging
  • Control of viscosity increase
  • Protection against bore polish
  • Control of varnish build-up and protection against corrosive attack
  • Protection against cylinder and piston ring scuffing

Details

MAIN APPLICATIONS
