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.
Look at the engine on your lawn mower. If the engine has an oil filler tube or a "hole" with a cap on it where oil is added to the engine, it is a 4-cycle (4-stroke) engine. If there is no oil filler tube or place to add oil to the engine, then it is a 2-cycle (2-stroke) engine and the oil has to be added to the fuel.
If it is a 4 cycle engine, yes, it does need oil. If it is a 2 cycle the oil is mixed with the gasoline.
Only if it is a two-stroke (two-cycle) engine.
If you put it in for engine oil you will have a major problem. If you put it in with the fuel then you will notice the mower smoking a lot and possibly fouling the spark plug.
4 cycle mower.... gas is separate from oil!
depends on the engine but it will be on the engine block.
A gas only engine has a spout where oil is added to the engine. If there is no spout, then it is a gas/oil engine. FYI - gas only engine is a four-stroke (four-cycle) engine and the gas/oil engine is two-stroke (two-cycle).
If its got a oil plug its a 4 cycle, 5w-30 motor oil
sae 30
If it is a 2-stroke engine, 2-cycle engine oil is added to the gasoline. If the engine is 4-stroke, regular 30W motor oil is used. To tell if your engine is 2-stroke or 4-stroke, look for a spout where oil is poured into the engine. If there is no spout, then the engine is 2-stroke and 2-cycle oil must be added to the gasoline.
2 cycle oil is meant to be used when your engine requires fuel/oil mix gas. If you have a dip stick for oil, your machine doesn't use mixed gas/oil.
No... it was ran low on oil & siezed up. junk mower now.
