As some of you know by know, I've gotten hold of a Karizma R for some time. The bike has clocked 1860km as of today.
Now, I know that HH reccomends a 10W30 grade oil for it. I have two queries regarding the oil.
1. What other alternatives do we have in 10W30 grade??
2. According to the user manual, the draining period for the HH 10W30 oil is 6,000km

. What is this all about? And has any karizma owner actually used the factory oil for this long??
