Well in India there are many key brands for motorcycle brands, like castrol, shell etc. Selecting oil for your motorcycle should be right one. Motorcycle oil come in grades. Rated for spark ignition.Oils are synthetic or natural, they many include detergents, grades (20W-50). Detergent additives acts like surfactants which minimizes tension.
You have to understand the type of oil is best for your bike. The thickness of oil is measured in SAE rating. The value of SAE should be lower so that it flows easily. Oil flows easy when heated. Oil may flow with 20 grade when cold and 50 when it has high temperature.
Get synthetic oil for most of your bikes, since synthetic can retain property much longer than natural oil. Multi Grade oil is good for engine.
To replace oil just see whether oil is hot, let it cool, remove the bolt at the bottom of the engine, replace with new one. You can also replace the oil filter periodically.
