For in-store pickup only, Advance Auto Parts offers the Sea Foam 128-oz. Motor Treatment for Gas and Diesel Engines for $52.99. Coupon code "SAVINGS" cuts that to $37.09. That's tied with last month's mention and the lowest price we could find by $16. It cleans deposits from internal engine parts and removes moisture from oil crankcases and fuel tanks.
