Yar 300KM par behtar hai. As during first few hundred KMs the engine produces a lot of friction as the internal parts gradually become accustomed to each other. As a result a lot of metal shavings and particles are produced, oil ka kam hota hai inhain sludge main trap kar lay. So that is why 300KM par jitna ragarnay wala kam hoga hojaye ga. Oil nikalain *** to andar say gund bhi bahir nikal aye ga.
Do not use Suzuki Oil it's a waste of money. I used it just once aur bike chalatay huay ghussa ata tha. Get havoline from Caltex headoffice although ye bhi pani ban jata hai at high temps. Liqui Moly is Rs650/- per litre agar apki pocket ijazat deti hai to yehi oil use karain
