Most engine manufacturers recommend SAE 30 NON-detergent oil. I've used that for 35+ yrs and have never had an engine failure. Just change it at the end/beginning of each season to get the most out of your equipment.
If the engine has an oil sump and an oil filler spout, it is a 4-cycle engine. On a 2-cycle engine, oil must be added to the fuel.
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
The type of oil you use depends on the type of engine you have. A good way to tell if it is a two-cycle or 4-cycle is to look for an oil filler cap - usually a screw-in cap about 1 to 1-1/2 inches in diameter. If the engine has an oil filler cap, it is a 4-cycle engine and you add 30-weight oil through the filler hole. If there is no oil cap, then the engine is a 2-cycle and you must mix 2-cycle oil with the gasoline. If it is a 2 cycle be sure and use only 2 cycle oil in the mix.

You can not use 4-cycle oil in a 2-cycle engine because the four cycle oil will not mix it is not designed to.Two cycle oil is designed to mix with fule to lube the two cycle parts in your motor.
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.
Only if it is a 2 cycle engine and you mix the oil with the gasoline. If it is a 4 cycle engine, then using 2 cycle oil will destroy the engine over time. Use SAE 10w30 synthetic oil in your air cooled 4 cycle engine.
Because a 2 Cycle Engine burns the oil in the gas, and in a 4 cycle engine, it sits in the oil pan, and it isn't supposed to burn it at all.
Oil is mixed with Petrol in what is known as a 2 cycle engine. This type of engine has no lubrication built in (as say an oil tank on a 4 cycle engine) so as the fuel/oil mixture burns lubrication is provided to the cylinder.
Use 4 cycle oil if the engine is a 4 cycle engine. Use 2 cycle if it is a 2 cycle. Use the weight oil recommended by the manufacture of your ATV.
The grade and viscosity of the oil
Yes, if it is a 4 cycle boat engine. However if the engine is a 2 cycle engine you cannot use automobile 4 cycle oil and must use 2 cycle engine oil.
