these days most bs6 engines recommended oil drain interval 6000Km or 6 months and check quality & quanity in every 3000KM topup if necessary with semi synthetic engine oils. 300cc bikes must use fully synthetic oil.
Most bs4 engines 3000KM or 3 months engine oil drain interval with mineral or semi synthetic blend before upto 2020 models.
Price of fully sythetic oil almost 2x than semi sythetic and longer interval better cleaning the egnine.
oil drain interval: if manufcaturer says 6000KM or 6 months . its better to cahnge at 4500KM or 5th month for better cleaning of engine.
Engine flush recommendation: every 3 service schedules after 1 year. or once in year better.
carbon cleaning: carbon between pistion and volves by fuel cleaning also better. you can check by cam through spark plug method. also there one time carbon cleaning amchines there cost of 1000-2000inr. beware losing heavy parts.
Standards: API – SP and JASO MA2 better comapred API-SN/ JASO MA.
Same viscotiy like 10w30 but every engine oil base oils and additive packages are different.
you can use fully synthetic but it 50% expensive for better protection high speeds.
only two poular brands are there for after market engine oils castrol and motul.
Castrol Power 1 and power 1 ultimate 10w30 engine oils for bikes
Note: there is a syntehtic blend cum mineral oil and fully synthetic engine oil at 50% extra price. more marketing logics applied.

Faqs on 10w30 bike engine oils
why 10w30 bike engine oil are semisynthetic instead of fully synthetic?
A 10W30 bike engine oil is often semi-synthetic instead of fully synthetic because it provides a good balance between performance and affordability, making it suitable for a wide range of motorcycles and riding conditions, while still offering better protection than conventional mineral oil, all at a lower cost compared to fully synthetic options; particularly for smaller or less demanding bikes where the added benefits of fully synthetic oil (heat & high RPM power, higher compression ratios) might not be necessary.
Can I use synthetic engine oil in a 100cc bike?
yes, you can use its waste of money. there is no overheat due to higher compression ratio. you get benefits of all synthetic engine oil.
can use mineral oil on 300cc bike
mineral oil breakes down easily and may not provide required lubrication extreme condtions drain intervals more frequent. high revs not smooth low power mabe engine damange due to high friction.
