Well "price wise". The battle between Quaker State & SuperTech is taking an effect to SuperTech's cheap oil price tag. At the Walmart here in Houston, if you go in the afternoon, Quaker State's shelves seems to be almost empty. Then the next morning store clerks fill it up with 5 qt jugs of Quaker State of different viscosities and later in the afternoon they're almost gone. Pennzoil & Valvoline lower prices are also right there just a hitting distance between Quaker State & Supertech. I must say SuperTech is in trouble, well in the stores here in Houston. I don't know in other cities in other states..
