 Welcome to AutoZone. What are you working on today? 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 five 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.
