It's a long time debated topic, over time with sludge developed during the engine life is not a small matter, with latest engine oil technology all manufactures adding essential additives to keep the cleanness of engine oil during the operational life. even though sometimes we unknowingly extend our oil change interval resulting in developing sludge inside the engine while you are removing the engine oil the old engine oil won't go out in full amount. the leftover will stick to the walls of the engine in hard form. one or two-time leftover won't make any issues directly. after a few numbers of an oil change, the accumulated old oil content will directly start effecting. you can check this. add a new engine oil any time and ride your bike for 400-500 KM and check the oil condition. The colour turns to be black if the oil is in the black condition that means the old oil leftover that sticks to the wall of the engine is diluted with new engine oil. so slowly the engine oil property will start to change. Also, you can use this test as a recommendation, if the oil color changes to dark black in a few hundred km, so with the next oil change you need to use an engine flush.
