 Sounds like you heard about a July 4th sale. It's a great chance to red, white, and do that job you've been putting off. Like an oil change with full synthetic motor oil. Right now, you can get 5 quarts of Pennzoil Platinum with an STP Extended Life Oil Filter for just $34.99. Save on oil, wash and wax, and more this weekend at AutoZone. Restrictions apply.
