When you use a Wal-Mart gift card or credit card to pay for gas at Wal-Mart, you get 3-cents off per gallon. Sounds like a pretty good deal. To top it off, Wal-Mart has the lowest gas price in our neck of the woods almost all the time.
BUT, an older gentleman informed me of results from unexpected experiment they had with gasoline from Wal-Mart and from another gas station. Since they were traveling to GA, they filled the tank here in Pensacola first. On the way back they filled up at a different station, since they didn't have any gas stations at the Wal-Mart there. Were they surprised at how much better gas mileage they got from the other station. From Wal-Mart's gas, they got 18 miles per gallon, as opposed to 22 mpg from the other.
We switched from Wal-Mart to another station to see if we had the same results. And we did, plus, the very next day, the car stopped trying to shut off. It ran smoothly at a higher mpg. I'm glad the told us. It's so important to share Frugal Tips! Share yours on Frugal Fridays.
