INJEX® TC-W3® 2-CYCLE MOTOR OIL
PREMIUM ASHLESS ENGINE OIL FOR 2-STROKE CYCLE ENGINES
Phillips 66® Injex TC-W3 2-Cycle Motor Oil is a premium ashless engine oil designed explicitly for water-cooled and most air-cooled 2-stroke cycle engines. This uniquely formulated oil offers protection equivalent to many OEM-branded 2-cycle engine oils. It holds the TC-W3® certification from the National Marine Manufacturers Association (NMMA) and meets API TC and JASO FB performance requirements for air-cooled 2-stroke cycle engines. It's suitable for both direct injection (DI) or premix engines.
This motor oil works to reduce piston ring sticking and exhaust port deposits, maintaining optimal power output in 2-stroke cycle engines. It safeguards against piston and cylinder scuffing while minimizing spark plug fouling and pre-ignition issues. The oil also provides rust and corrosion protection during service and storage. Pre-diluted with a high-flash solvent, it mixes easily with gasoline at low temperatures for premix applications and includes a synthetic polymer to help reduce exhaust smoke.
