Help, how do I care for wooden patio furniture?

I recently purchased a dark wooden patio set, and unsure of how to maintain it. the wood was treated with linseed oil, now do I remove the linseed oil and and seal it with a product, or do I just leave it? I am not too sure if we'll be able to put the patio furniture away in the winter, so it might be stuck outside all winter! also, i don't want the sun to strip to much of my colour, can anyone help? the following link is for the smaller version of my table, please look at the bistro table, and picture mine double the size... thanks in advance

Is the wood teak? If so, no need to worry. Teak are good for outdoors. you can also ask paint technician for the best coat for outdoors and treatment.
