Marine TPEO SAE 40

Supreme 7000 Synthetic Plus Straight Grade

590 Marine TPEO 30TBN SAE 40
595 Marine TPEO 15TBN SAE 40

Marine TPEO meets the performance requirements of medium to high speed 4-Stroke ‘Trunk Piston’ diesel engine oils utilizing Ultra Low Sulfur Diesel. These engines operate under severe conditions which requires better corrosion resistance, detergency, oxidation resistance and thermal stability.

Further blended into Marine TPEO are two proven frictional modifiers, Micron Moly®, a liquid soluble type of moly, and Schaeffer Mfg.’s own proprietary additive Penetro®. Once plated, these frictional modifiers form a long lasting, slippery, tenacious lubricant film, which prevents metal-to-metal contact and damaging frictional wear.

Marine TPEO can be used in the following applications:

  • Medium to High speed 4-Stroke trunk piston diesel engines
  • Certain marine and stationary diesel engine applications

Performance Benefits

  • Excellent load carrying and anti-wear protection; strong scuffing protection.
  • Advanced detergency and dispersancy technology.
  • Enhanced alkalinity (BN) retention.
  • Controls sludge and varnish.
  • Corrosion and rust control.
  • Good filterability and water shedding.
