Part-Synthetic Engine Oil for 4-Stroke Cycle Motorcycles, Scooters & ATVs

Kendall® 4T Semi-Synthetic MB is a premium quality, part-synthetic engine oil designed primarily for use in 4-stroke cycle motorcycles, scooters, and all-terrain vehicles (ATVs). It also may be used as transmission oil in motorcycles and ATVs where the manufacturer specifies the use of motor oil in the transmission.


Features & Benefits

  • Enhanced resistance to viscosity and thermal breakdown at high temperatures
  • Protects against sludge and varnish formation
  • Protects against scuffing and wear
  • High shear stability
  • Protects against rust and bearing corrosion
  • Good resistance to foaming and air entrainment


  • 4-stroke cycle motorcycles, scooters, and ATVs
