Oil esp. two cycle oil has begun to take on almost magical powers in hearts and minds of OPE makers and owners. Most 50 to 0ne OPE require JASO FC and or FD oils nowdays. More letters and numbers are included and more seem to be added about every time you turn around. Any Oregon dealer can order you in JASO FC oil by the gallon for 35 bucks, smaller containers for about the price of one dollar per gallon of mixed gasoline for the oil. Mystic oil can be had in FC and FD for about 35 bucks a gallon plus shipping and 5 bucks a quart plus shipping. Some of these oils are certified and some are not. FB oils are about everywhere for 3 to 5 bucks a quart. Menards has Quaker State universal air cooled for $3.50 a quart out the door. I can get the same type of oil at the grocery store here in Phillips 66 for less than five a quart. Decide what kind of oil you want and what kind you need and go shopping. Bear in mind what type of oil your warranty requires and OPE requires. If you indeed use large quanities oil distributors offer high quality two cycle oils in five, thirty, and I think I have seen a couple advertised in 55 gallon drums.
