Honda oil
 

I recently purchased 1994 honda xr100r with no manual. It is very low on oil, and i need to know what kind of oil to use. I have herd it uses 10w30 or 10w40, but am still not sure. Also if anyone could link me a manual to download, or look at on the web that would be nice:)

Thanks for your help in advanced
