When is it time to change the oil filter on my home oil furnace?

I have an old Valiant oil furnace with a Sid Harvey XF-25 canister and wool filter. I bought the house in Nov. 2006 and there was little information about the furnace. I'm going to change it now, but is there a definite time between changes?
