I've been looking for Pennzoil Ultra 5W-30 motor oil in my local stores (Columbus, OH) and almost no one seems to have any in stock. Pep Boys has it for almost $10/quart. It seems that other than Pep Boys the only other place I can find it is on Amazon.com. In fact Walmart has stopped carrying it for some unknown reason. Does anyone know if the Pennzoil Ultra 5W-30 oil is being replaced with something else? Or does anyone know where else I can find the oil at a cheaper price than $10/quart?
