I don’t think I have ever seen a coupon for this before!
Right now you can print a coupon for $1 off STP Gas Treatment coupon.
Check under zip code 23320 and “automotive”.
It is only $1.69 at Walmart so this is a great price.
STP® Gas Treatment improves the quality of gas by adding powerful cleaning agents that help fight the accumulation of harmful carbon, gum and varnish depositsin the fuel system that can reduce performance. Also engineered to remove water, which can lead to fuel line freeze.
Thanks My Litter!
