Our store does not have the 15W50 in 5 quart containers, but the Wal*Mart in Meadville PA does (30 mins away). The Meadville store is also stocking M1 0W20 and M1 0W40 (in 1 quart bottles) in addition to the 5W30, 10W30 and 15W50.
I noticed the Edinboro store is selling about 4 or 5 times as much 5W30 as 10W30 in the 5 quart containers.
Does anyone know if these 5 quart containers are here to stay, or if it is just a 1 time thing? I bought 15 quarts, but if they are going away, I may buy some more.
