4T Semi-Synthetic MA

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

Phillips 66®4T Semi-Synthetic MA 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
