I'm not sure about WV, but here in northern CA M1 0-20 seems to be at most Wal-Marts in various ranges of $3.99 to $5.99 qt. Here, Kragen is the equivilent to Checker Auto and looking at the Kragen ad, they have a coupon for $1.00 of per qt of M1 synthetics. Some have said you can get any auto parts store to order 0-20 if they don't have it in stock.
