4 stroke motor oil

[teacherman]

I have a Johnson 2001 90 hp 4 stroke motor. Time for another oil change and wanted to know what oil to use. I have used Johnson synthetic in the past and have been very happy with it except the price. ($9.95/qt.) I live in a rural area and have a limited choice of people to buy oil from. Is there any other type of oil I can use that would ease the pocketbook or a site I could order from that has a good reputation?
