Two-stroke oil

Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, or 2-stroke oil) is an engine oil intended for use in two-stroke engines like those in many lawnmowers, Outboard motors, etc. Since these lightweight engines do not feature oil sumps to collect and recycle oil like 4 cycle engines, oil must be mixed into the fuel mixture for distribution throughout the engine for lubrication and is ultimately burned along with the fuel resulting in exhaust emissions such as blue smoke and a distinctive odor.

The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with petrol/gasoline with the fuel at a oil ratio ranging from 20:1 to as high as 100:1.

Engine Original equipment manufacturers, (OEM's) introduced pre-injection systems to engines to operate from a 32 : 1 to 100 : 1 ratio. Oils must meet or exceed the following typical specifications : TC-W3TM, NMMA, [API] TC, JASO FC, ISO-L-EGO.
