The type of oil used in gasoline generators is similar to that in cars, and four-stroke gasoline engines are commonly used. There are two types of gasoline generators: two-stroke and four-stroke. You need to see the number of strokes of the gasoline generator and then choose the corresponding engine oil model.
Four-stroke gasoline generators usually add 15W-40 engine oil or 5W-30 engine oil.
Generally, two-stroke gasoline generators are mixed with blended oil, and it is best to replace them with two-stroke engine oil. If there is no special oil for gasoline engines, you can use special oil for two-stroke motorcycles. Their oils are the same. It is best not to use car oil or other four-stroke oils, including those for four-stroke motorcycles. It is much easier to accumulate carbon.
Lhe specific function of engine oil: When the engine cylinder pressure increases sharply, the load on the piston, piston shavings, connecting rod and crankshaft bearing is very heavy. This load is lubricated by the bearing, so that. the impact load of the bearing acts as a buffer; lubricating oil can be adsorbed on the surface of parts to prevent water, air, acidic substances and harmful gases from contacting the parts; the main shaft and the bearing shell. In order to avoid too rapid wear of the parts, a film of oil must be established between the two sliding surfaces. An oil film of sufficient thickness will separate the surfaces of relatively sliding parts, thereby reducing wear. The oil carries heat to the tank and releases it into the air, helping the tank cool the engine.
