Quote:what does the SH stand for ? pardon my ignorance.
I know that the "S" stands for passenger vehicles, a "C" rated oil is for commercial vehicles. I am not really certain what the "H" stands for. If you are really that concerned about using the "best" oil in your bike, go with the oils specifically formulated for motorcycles. From what I understand, you will pay a bit more per quart. I am not sure exactly what the premium per quart is, but I have heard that it is somewhere around $.50 per quart. Whether or not it is really necessary is up for debate (see previous oil threads). However, if it will ensure your peace of mind, do it.
That being said, I don't use it. I merely use standard automotive oil that is not designated energy conserving. I have never had a problem, YMMV
