Cool, good price too ... and my Durango takes exactly 6 quarts, however wouldnt be worth the trouble with the other cars, hate having 1+ quarts of oil left over. (first thoughts anyway)
Right now Im using conv. Chevron Supreme 5/30 in my wife's Mazda Skyactive and my 4.7 liter Durango and cost $12.42 for 5 quart cont. delivered to my house with Walmart.
Im not seeing the boxed oil in their website, but we do have two Walmart supers centers right near us, will check it out. Worth it for the 6 quarts for the Durgano for sure.
