4-cycle oil cannot be used instead of 2-cycle oil under any circumstances. 4-cycle oil has a very low flash point, which means it can ignite and burn easily at low temperatures. This can cause serious damage to your engine, and can also cause a fire.
In addition, 4-cycle oil does not have the necessary components required to protect the internal parts of your engine. This includes additives that help to clean your carburetor, as well as components that help to reduce friction and lubricity in your engine.
It is important to remember that 2-cycle oil and 4-cycle oil are not interchangeable. Using 4-cycle oil in a 2-cycle engine is extremely dangerous, and should not be attempted.
