Unlike four-cycle engines which use a closed crankcase, the 2 stroke / 2 cycle lightweight engine use an open crankcase, this being used as part of the induction tract. As the crankcase can therefore not be used to contain the necessary lubricating oil. Oil must be mixed with petrol to be used throughout the engine in high enough quantities to ensure lubrication and yet also not being high enough to cause issues with combustion.
The base oils used can be either petroleum, vegetable, semi-synthetic or synthetic oil and the mix ratio with the petrol/gasoline ranging from 16:1 to as low as 100:1.
With such low ratios being used, it becomes vitally important to use the right oil for the job, this varying according to the type of 2 cycle engine and the loads and conditions that it will be used in.
Another issue that must be considered when comparing regular lubricating oil with two stroke oil, is that 2 stroke oil must produce a much lower ash content. If this is not done the deposits formed by the act of combustion will build up in the engine, causing fouled plugs, lack of efficiency and eventually damage to the engine itself.
