FAQ:

Q: What kind of oil does a 4 stroke engine use?

A: AMSOIL Formula 4-Stroke Power Sports Synthetic Motor Oil is recommended for four-stroke engines. It is also recommended for transmissions in two- or four-stroke applications. It is an all-climate/all-season oil that replaces 0W-30, 0W-40, 5W-30, 10W-30 and 10W-40 oils for ATVs, UTVs, snowmobiles and other powersports equipment.

Q: What oil do you use in a 4 stroke generator?

A: The most common oil used with 4-stroke engines found in generators, lawnmowers, and other related equipment is SAE 30. You can also go for its synthetic variations such as SAE 5W-30 and SAE 10W-30.

Q: Can You Put 4 stroke oil into 2 stroke engine?

A: That isn’t really a good idea. First off, two stroke oil is a bit different than ordinary four stroke oil, as it is designed to mix with gasoline and lubricate all the moving parts that a four stroke engine does with splash or pressurized oiling.

Q: How is a 4 stroke engine lubricated?

A: Four-stroke engines are lubricated by oil held in an oil sump . The oil is distributed through the engine by splash lubrication or a pressurized lubrication pump system; these systems may be used alone or together. Splash lubrication is achieved by partly submerging the crankshaft in the oil sump.
