T5X® HEAVY DUTY DIESEL ENGINE OIL

HEAVY-DUTY MONOGRADE DIESEL ENGINE OIL

Phillips 66® T5X Heavy Duty Diesel Engine Oil is a high-quality diesel engine oil designed for use in a wide variety of applications, including off-highway diesel equipment, farm machinery, marine engines, 2-stroke cycle diesel engines (SAE 40 only) and mixed commercial fleets. It also may be used in some heavy-duty manual transmissions in trucks and buses.

T5X® HEAVY DUTY DIESEL ENGINE OIL

Features & Benefits

  • Excellent soot control for protection against abrasive wear and soot-induced oil thickening
  • Protects against sludge and varnish formation
  • Protects against scuffing and wear
  • Protects against rust and bearing corrosion
  • Good resistance to foaming and aeration
  • Low-ash content to minimize ash deposits and help keep intake ports clean (SAE 40)

Applications

  • 2-stroke cycle diesel engines in bus fleets and marine fleets (SAE 40)
  • Off-highway trucks, heavy equipment and farm equipment
  • Light trucks and farm equipment with gasoline engines (SAE 30, SAE 50)
  • Heavy-duty manual transmissions in trucks and buses where the OEM specifies engine oil
