In 2 strokes bike, 2T oil is used to lubricate the piston and
combustion champer. 4T oil is the engine oil use to lubricate the
gear, clutch etc.
4 strokes engine need only engine oil.
(You can refer to my earlier post about how 2 strokes engine
work).
Run in ?
Riding not exceeding 60KM/h for the first 500KM, change engine
oil.
Then not exceeding 80KM/h for the next 1000KM. change engine oil
again at 1500KM, after that, you ride at any speed as long no
exceeding the law permitted.
