I would have posted this on the ongoing Autozone clearance thread but I think it would get lost in the static of 10 plus pages now.
Two local Auto Zones have Pennzoil Ultra on sale, 5w-30 and 10w-30 for $4 per quart. One store has the older version dated Jan 2013 the other has the newer version Date unknown.
At $4 per quart is it worth it to buy? With 2 cars that takes 6 quarts and 3 oil changes per year, how many quarts should I buy before the oil is to old to be used?
That said, should I get the newer version or the older version?
