Drain interval of car oils is not relevant to motorcycle engines , since car oils are not stressed as much and do not have to perform half as many functions .
Be less worried about API rating (claims) of oils because I can say for sure that none of the oils you have/are using on your motorcycle has been really tested or certified by API at all .
If it had passed all the rigorous API (American Petroleum Institute) tests and were duely certified , your oil bottle label would bear a true API donut badge like this ... check it .

Beware of the fake API-like badge used on some oil bottles too ...

What motorcycle oils should have is this symbol or badge with the certification number , rather than API . Not all oils have this even .... and fake / like symbols are not unknown of this one too .
Mere claim or mention of an API or JASO rating , grade or conformance amounts to just that - a mere claim . Very few companies in India actually sent their oils to the American or Japanese certification laboratories to pass the tests and obtain certificates (including a few of motul's oils) . Maybe they are confident that indians shall not be able to read it
.Can anyone check a bottle of Bajaj's 10000Dtsi oil and tell me if that bears these API / JASO badges and certification numbers ?
. nahi ?





. I have no confidence on a manufacturer certifying it's own product to conform to a certain independent standard .
