What is the gasoline ratio of a two-stroke gasoline engine?

The gasoline: oil ratio of a two-stroke gasoline engine is 30:1.
The mixing ratio of two-stroke gasoline engine oil should generally be controlled between 27-30:1 as the best. If long-term or overloaded operation is required, the mixing ratio should be adjusted appropriately.
The principle of a two-stroke gasoline engine is:
In a two-stroke gasoline engine, gasoline and lubricating oil enter the carburetor in a certain proportion, and the lubricating oil forms fine oil droplets that enter the friction surface. Due to the use of crankcase ventilation in two-stroke engines, when a mixture of fine oil droplets enters the crankcase, some oil droplets attach to the surfaces of various parts such as the main bearings at both ends of the crankshaft and the bearings at both ends of the connecting rod, lubricating these components.
The fine oil droplets attached to the cylinder wall form a layer of oil film, which flows from top to bottom, lubricating the friction surfaces of the piston, piston ring, and cylinder wall, and finally mixing with air to enter the cylinder for combustion.
