Synjex®TC-W3®2-Cycle Motor Oil

Premium Full-Synthetic Ashless Engine Oil

Phillips 66®Synjex TC-W3 2-Cycle Motor Oil is a premium quality, full-synthetic, ashless engine oil designed for use in high-performance water-cooled 2-stroke cycle engines, and in most air-cooled 2-stroke cycle engines. It is particularly recommended for use in equipment operating at very low ambient temperatures. It is suitable for use for TC-W3 applications, and also meets API TC and JASO FB performance requirements for use in air-cooled 2-stroke cycle engines. It may be used in either direct injection (DI) or premix engines.

Features & Benefits

• Ashless detergent/dispersant formulation helps minimize engine deposits and pre-ignition

• Minimizes piston ring sticking and helps reduce exhaust port blocking

• Protects against piston and cylinder scuffing

• Excellent lubricity for use in high-output outboard engines

• Reduces spark plug fouling

• Excellent rust and corrosion protection

• Outstanding low temperature performance

• Keeps engine parts clean

• Readily biodegradable

• Low aquatic toxicity

• Mixes easily with gasoline at low temperatures for premix applications

• Dyed for easy visibility when mixed with gasoline

• Suitable for either direct oil injection or premix engines


• Outboard marine engines

• Personal watercraft

• Motorcycles, scooters, and all-terrain vehicles (ATVs)

• Snowmobiles
