parts availability with old furnace?

I bought and remodeled a home in Alaska, the furnace hadn't been used in 20+ years, the previous owner only used the house during summers and chose to use a fireplace if needed. He told me the furnace was only used for about 10 years before by the owners before him, my take on it is, it should have at least a few years of life in it.

It is a sears roebuck oil fired "high efficiency" model, not sure how to gauge the year from the serial number. It is ~85k btu and has a .75gph nozzle.

I was planning to replace it when I bought the house, but after replacing the fuel lines and filters, the furnace fired up with no issues, and was surprisingly quiet. I have C02/smoke sensors in all of the rooms and have not detected any issues so far. Is it fairly easy to find parts for these older models? I appreciate the simplicity and ease of use. Only thing I am expecting to do is oil the blower, other than that, any reason to get rid of it? At the same time, I installed a honeywell wifi thermostat, if that counts as an improvement.

You should probably get it cleaned and tuned professionally.

One thing to think about is efficiency -> a 30 year old oil furnace is probably only 60-70% when perfectly tuned. You can get 80%+ today with oil, 95% if you switch to propane.

If u have natural gas available, switch for sure.
