This oil gets mentioned a few times so I thought I would post. Just got their flier today in the mail. Trop Artic 10W-30, 5W-20 and 5W-30 will be $1.79 a quart at Orscheln Farm & Home stores from April 14th thru the 19th. Google them for a store locator, but they are mainly a midwest farm supply store. I haven't used this oil for about 5 years out of principal, but I may have to stock up now. The store also has Shell 5 gallon containers of 15W-40 for $54.99, which may or may not be a good price to some of you out there.
