Four-stroke engines have a spout where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
, I have a BP75AR rally mower. Its very old.It has a Briggs 4 cycle engine. Good luck. Mike
If it is a 2-stroke engine, the oil/gas mixture has too much oil. If it is a 4-stroke engine, the oil sump is overfull.
Yes, all two stroke oil can be used in any two stroke engine. It is cheaper to buy it in a gallon jug from the auto parts store than to use the little cans of lawn mower oil.NO... as there is a difference between air cooled 2 stroke oil and water cooled oil, Most makes of air cooled oil usually have a warning on it stating noyt for use in water cooled engines.
what is the different a bumblebee and a lawn mower
Either it is a 2 stroke(in which it's normal), or if it's a 4 stroke it has worn rings and is burning oil
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 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.
Only if it is a two-stroke (two-cycle) engine.
You did not specify which brand of 2-stroke lawn mower you have. So, the ratios may differ. For a Briggs & Stratten 2-stroke engine the ratio will be either 50:1 or 32:1 depending on the engine model. It is always advisable to check with the manufacturer's manual or on the internet.
it all depends if it is a 2 stroke or a 4 stroke lawn mower
Use regular unleaded gasoline, and mix it with four ounces of oil per gallon of gas - BUT, how you use it depends on whether your lawn mower has a 2-stroke or 4-stroke engine. A 2-stroke engine requires 2-cycle oil to be added to the gasoline in a certain ratio. 4-stroke engines do not require the gas/oil mixture.
Single-acting? You mean like a single cylinder engine, like in my lawn mower? The biggest difference (besides the obvious "an opposed engine has more cylinders" is that an opposed engine has more torque. On a single-cylinder four-stroke, you've got the cylinder moving under input energy--the burning gasoline--for one stroke, and under stored energy from the flywheel for three strokes. If you have a two-cylinder engine, you have two strokes where the engine is moving under input energy--each cylinder has one--and two strokes using stored energy. If you have a four-cylinder engine, each stroke is moving under input energy.
