Two-cycle lawnmower engines are rare.
Depends on the lawnmower. Some older lawn mowers used two-stroke engines, and you mixed the two-cycle oil with the gas. But 99% of modern lawnmowers use a four-stroke engine with a crankcase. So if the question is: "Can I use two-cycle oil in the crankcase?" the answer is an emphatic NO. It will likely destroy the engine.
To lubricate the motor to prevent overheating and wear and tear on the engine
All automobiles use 4 cycle engines. 2 cycles are for small moterized bikes or lawn mowers
Lawn mowers can take 2 stroke or 4 stroke oil depending on the type of engine. If unsure contact your lawn mower provider.
Most all riding mowers use SAE 30 oil.
Scythes.
No. Do not use in your car. It is for use in some lawn mowers and aircompressor motors.
If its got a oil plug its a 4 cycle, 5w-30 motor oil
The gas used is the same. You just need to be sure that neither one of them are 2 cycle. Or that they both are 2 cycle. Most lawn mowers are 4 stroke whcih means they use the straight gas right out of the pump. Dirt bikes can use straight gas or gas mixed with oil.
Lawn mowers are not destroyed after a single use, and they retain usefulness for many years, so, yes, lawn mowers are durable goods.
Um... because they have an engine like your car that has moving parts and cylinders... only significantly smaller?
