Oil is used in the engine for lubrication and for cooling. If the engine did not have oil it would overheat and soon seize from the heat and wear on engine components. This would destroy the engine in a very short period of time.
No, seals are cheap, engines expensive.......
Most small engines will run on 30w oil .
most engines take 5w30 unless the oil cap says otherwise
Not recommended. The engines call for 5w30 or 5w20.Not recommended. The engines call for 5w30 or 5w20.
You will be fine with 10w-40 ATV or motorcycle oil designed for wet clutch engines.
Because oil is vital for lubrication and cooling of the pistons, and without it, the engine would seize and be ruined.
You can put whatever oil you want to put in an engine as long as it is the right weight (10W-30, 5W-30 etc...) and it says "made for gasoline engines".
No not the oil filters, just the fuel filters You don't have to. But I put oil in them when I can. Just the way I was told to do it when I first started working on engines.
2-stroke engines run on a gas-oil mixture put directly into the gas tank. They do not have a crankcase that holds oil separately like most normal 4-stroke engines.

You should drain the oil in the engine. Put engine oil back in the engine because the transmission oil is not made for engines and will hurt the moving parts of the engine if left in.
The oil light is turning on BECAUSE you put in the lighter weight oil. older engines need the thicker oil.
