Never heard of Roush Racing Pennzoil, except for the stuff we provide Jack Roush with for his Fords, and I can assure you it would be more like $6.00 per quart IF you could buy it.
Was this something where the case had a pictue of a Roush Ford on the box with regular Pennzoil 5W30 in the yellow bottles in it. If so, it's just regular Pennzoil that Wal-Mart might have on sale for some reason.
