Hello everyone on this cold Feb day. My oil furnace is running fine but I'd like to change the oil filter at the end of the oil tank. First question- is this easy to door must a professional do it? Looks like you shut the valve, unscrew the filter, take old one off & put new one on, yes? Second question- would my or a oil company sell me a filter, or can I buy one on line? Third question- should an additive, like Technol, be added periodically?
Thanks in advance.
