can we use car oil for our bikes? and what's the diff.
cheers
There is no such thing as "CAR OIL" nor is there such a thing as "BIKE OIL"
There
is oil that conforms to a certain standard that one engine manufacturer calls for, and there is other oil that conforms to some other standard that some other engine manufacturer calls for.
Read your owner's manual, and read the fine print on the bottle, where it says what standards that the oil conforms to.
A very typical one that a good many motorcycle manufacturers call for the oil to be in compliance with, is JASO-MA. But, often the manual allows for the use of oil that meets any one of several different standards.
If that is what your owner's manual calls for, and that's what the bottle says, then it is good.
(The difference, by the way, is in the various additives that are present in the oil for all sorts of different objectives - extreme-pressure, or anti-foaming, or resistance to certain types of contaminating elements, etc. Different engines that have different design elements or materials inside them or different operating temperatures, require different additive packages.)
