Only if you want to destroy that engine over time which is what will happen if you use 2 cycle oil. Use only SAE 10w30 synthetic oil any major brand.
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.
If you have to add oil to the fuel, it is a 2-cycle engine. If you have to add oil through a filler spout into the crankcase, it is a 4-cycle engine.
Sae 30w
A Craftsman 917388592, has a 4-cycle, Briggs & Stratton engine.
NO, not as lubrication in the crankcase.
usually sae 30, unless it's used in weather under 50 degrees then you can use 10w-30, but you didn't specify what kind of motor it is. 2 cycle or 4 cycle. Use Synthetic oil in any air cooled engine.
2 Cycle engine oil.
You can, but if it is not water-cooled then it will not lubricate correctly since an air-cooled engine runs at nearly or greater than the temperature of a water-cooled engine.
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.
Most 2 cycle outboards are in fact water cooled. There were a few air cooled models, in the smaller hp range, produced years ago. Though there may be an air cooled engine in current production, I am not aware of it.
Yes, It will probably smoke due to the extra oil that is burning but will will work in a pinch. Not recommended for extended use.
You can cut down trees with your lawnmower. Warning: Do not actually try to cut down a tree with your lawnmower. More than likely, the gas in the chainsaw is mixed with 2-cycle oil. If your mower also has a 2-cycle engine, nothing will happen. If your mower has a 4-cycle engine, the engine will probably smoke (bluish in color) until the oil is burnt up during combustion. At worst, the oil in the 2-cycle oil/gas mixture will foul up the spark plug and you will probably have to clean it pretty often until the oil is burnt up.
