* Gasoline (Petrol): This is the most widely used fuel for 2-stroke engines, especially in small engines like those found in lawnmowers, chainsaws, and motorcycles.
* Pre-mixed fuel: This is a mixture of gasoline and 2-stroke oil, which is typically pre-mixed in a specific ratio by the manufacturer.
* Diesel: Some larger 2-stroke engines, like those used in marine applications, can run on diesel fuel.
* Biodiesel: Biodiesel can also be used in some 2-stroke engines.
It's important to note that 2-stroke engines require a lubricating oil to be mixed with the fuel, unlike 4-stroke engines which have a separate oil sump. This is because the oil is used to lubricate the engine's moving parts and also to seal the crankcase.
The type of gas used for a 2-stroke engine will depend on the specific engine and its intended use. Always consult the engine's owner's manual for the recommended fuel type and oil mixture ratio.
