It's always fun to look at the oil section at supermarkets. Sometimes you find interesting stuff, like the "Motor Honey" at a Farmer Jack nearby. A Kroger had Durablend for something like $2.99, noting regular price around $3.59 or something like that. True too. If you go to an old fashioned type auto parts store, the Durablend will be around $3.59. One parts store wanted $5 for Durablend. When I complained, the guy said, "this stuff has synthetic in it." Thankfully I bought my Durablend stash for $1.98 and $1.88 a quart at Pep Boys sales.
