FAQ:

Q: Is a 4 stroke more powerful than a 2 stroke?

A: Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. Two-stroke engines are a much simpler design, making them easier to fix. They do not have valves, but rather ports.

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

A: You should use either a 4 stroke 10W30 (or 10W40) oil or an SAE 30 oil in your 4 stroke generator unless the generator’s operation manual specifies otherwise. Some generators will also be able to use a synthetic 5W30 oil which is ideal if you are using the generator in colder temperatures.

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

A: 4 stroke oil is used in 4 stroke engines where the oil and gasoline are separate. A car engine for instance is a 4 stroke engine. 2 stroke oil references gasoline engines where the oil and gas are mixed. Examples include chainsaws, lawnboy lawn mowers and other small engines.

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.
