I get most of my oil in 6 gallon boxes. Price of name brand syn blend that we use is up 25 percent in the last 6 months. Depending on brand bulk oil is in short supply which is driving places that would usually get oil in bulk to use packaged oil which is more expensive. When my oil salesman was in wednesday he was telling us that they are out of Pennzoil 0w20 in everything but quart bottles and have been for months.
