Gas Prices in Forney & Kaufman County: Where Locals Actually Save
If you live in Forney, Talty, Heartland, or anywhere else in Kaufman County, you already know: most of us drive a lot. Whether you’re commuting to downtown Dallas, to a job site somewhere in the metroplex, or just running kids to school and practice, gas is one of the bigger lines in a Forney family budget.
Here’s where locals actually save money on fuel — and a few common things that don’t pay off.
The Cheapest Gas in Forney (Right Now)
A quick local-knowledge breakdown. Prices change daily, but the order tends to stay the same:
- Costco Fuel (US-80 at FM 460, Forney). Open since February 2025. Almost always the cheapest in town for cardholders. Lines can be long mornings and Sunday afternoons — best after 6 p.m. on weeknights.
- BJ’s Wholesale Fuel (coming to The Village at Gateway). Will compete directly with Costco. Members-only. Worth comparing once it opens.
- Murphy USA at Walmart, US-80 Forney. Reliably cheap, no membership required. Cash pricing is best.
- Sam’s Club (Mesquite). Cheap, but the drive eats most of the savings unless you’re already over there.
- QuikTrip (US-80 Mesquite, Sunnyvale). Premium-feel stations, slightly higher than Murphy, very clean. Worth it on long drives.
The high end you generally want to skip on a routine fill-up: branded full-service stations off the interstate exits, especially the ones near new neighborhoods. They tend to run 20–40 cents above the local floor.
Apps That Actually Help
Two apps do most of the work:
- GasBuddy — community-reported prices, decent in our area. Best for finding deals when you’re already out of your usual orbit. We have a full GasBuddy guide for Forney if you want to set it up properly.
- Upside — cashback on gas (and groceries). Works at Murphy USA and several local stations. Stacks on top of the cheapest pump price.
Honest take: if you fill up at Costco fuel most of the time, a GasBuddy alert isn’t going to save you much because you’re already at or near the cheapest pump in the county. The apps matter most for people who fill up wherever they happen to be.
When Driving Out of Town for Gas Doesn’t Pay
Common Kaufman County mistake: driving 15–20 minutes to chase a 15-cent-per-gallon difference.
Quick math on a 15-gallon tank:
- 15¢ × 15 gallons = $2.25 saved.
- 30 minutes round-trip burning ~1 gallon at $2.85 = $2.85 in fuel + 30 minutes of your life.
You’re not actually saving anything. The savings come from going to the cheap station that you would already be near, not from driving out of your way.
This is also a real argument for keeping your gym, your groceries, and your fuel within a tight loop — which is finally possible in Forney now that The Village at Gateway is filling in.
The Hidden Tax: Driving Out of Forney for Gym, Groceries, and Errands
The bigger fuel-cost story for most Forney families isn’t the per-gallon price — it’s the number of trips outside town. If you’re driving to Mesquite for the gym, Rockwall for groceries, and back into Forney for everything else, you’re easily putting 2–3 extra gallons a week into errand miles.
Three to four times a week, that’s $20–$30 a month in pure errand fuel. Per year: $250–$350. Roughly the cost of a low-tier gym membership, in fuel you didn’t have to burn.
Train Where You Live
TX Fitness has been at 127 E US Highway 80 in Forney for over 25 years — five minutes from Costco fuel, the new Walmart, and most Forney neighborhoods. If your gym is on your way home, it gets used. If it’s a 25-minute drive away, it doesn’t.
The cheapest gym membership is the one you don’t need to drive across the metroplex to use.
