Which countries besides the US does Saudi Arabia sell their oil to?
By far, the vast majority of Saudi exports are crude petroleum (77%) and refined gas (7%), and it is bought by Asia (China, Singapore, Etc., 38%) and secondarily by North And Central America (8%). See here: http://atlas.media.mit.edu/country/sau/
To china and England, and a few more that I don't know
Most goes to Asia, we only import about 7 or 8 %. We import more than twice the oil from Canada as we do from Saudi Arabia. Canada is second to Saudi Arabia, in global oil reserves.
