Which Walmart stations have diesel?
Diesel is sold at 1,437 of the 1,545 Walmart-lot stations we track (93%), across 31 states. The pumps are a mix of two operators sharing the same parking lots: Murphy USA kiosks account for 1,003 diesel locations (of 1,093 Murphy-in-lot sites), and Walmart-operated fuel stations account for 434 (of 452 Walmart-branded pumps).
Don't skip Neighborhood Markets: 258 of 260 Neighborhood Market fuel sites in our data report diesel. Search above or use Walmart stations near you and open the station page — if diesel is not on the price list, that store does not sell it.
DEF at Walmart: pump vs Auto Care jugs
DEF (diesel exhaust fluid) is not diesel, and this page does not track jug prices. At a standard Walmart or Murphy USA canopy, you buy DEF inside the store, not at the island. Supercenters with Auto Care — 1,100 of the locations we track — stock 2.5-gallon jugs of Super Tech DEF or Peak BlueDEF, typically $9 to $14, often well under truck-stop convenience-store pricing. None of the Neighborhood Markets in our data have an Auto Care department, so jug DEF is a Supercenter stop.
Bulk at-the-pump DEF is uncommon at parking-lot kiosks. You will find it mainly at larger Murphy Express or Murphy USA travel-plaza sites, not at a typical Supercenter island. If your truck or SUV is low on DEF, plan on a boxed jug. For ULSD specs, cetane, biodiesel blends, and winterization of the diesel itself, see Walmart diesel fuel quality.
Truck, RV, and trailer access at Walmart diesel pumps
These are retail parking-lot forecourts. Pickups, vans, and many travel trailers can fuel here if you take an outer lane and obey the clearance marked on the canopy. They are not Pilot/Love's-style truck stops: there is no dedicated truck island, no high-speed DEF dispenser at most sites, and no truck parking. Class 8 tractors and oversized fifth wheels should not count on making the turn or clearing the canopy. If the island is tight, skip it — the cheapest diesel on this list is not a bargain if you clip a dispenser.
Walmart+ knocks 10¢ off each diesel gallon at participating Walmart and Murphy USA pumps when you redeem in the app. Details, redemption steps, and what does not stack are in the Walmart+ gas discount guide.
Walmart diesel and DEF: FAQ
- Does Walmart have diesel fuel?
- Yes. Diesel is on the sign at 1,437 of the 1,545 Walmart parking-lot stations we track (93%), spanning 31 states. 1,003 of those diesel pumps are Murphy USA kiosks in the lot; 434 are Walmart-operated. Confirm diesel on the station page or the canopy before you drive over — a Supercenter with gasoline is not a guarantee of diesel.
- How much is diesel at Walmart today?
- The Walmart U.S. diesel average is $5.617 per gallon today, $1.709 above the Walmart regular average of $3.908. Wyoming currently has the lowest state average at $5.389; California is the highest at $7.268, a $1.88 spread. Prices are set per station, not nationally.
- Does Walmart sell DEF (diesel exhaust fluid)?
- Walmart sells DEF as boxed 2.5-gallon jugs — typically Super Tech or Peak BlueDEF, often $9 to $14 — in the Auto Care department of most Supercenters (1,100 of the stores we track have Auto Care). Neighborhood Markets do not have Auto Care, so jug DEF is a Supercenter errand. This page tracks per-gallon pump diesel, not jug DEF shelf prices.
- Is DEF at the pump or only in the store at Walmart?
- At a typical Walmart or Murphy USA parking-lot kiosk, DEF is in the store, not on the island. Bulk at-the-pump DEF is a truck-stop feature and shows up mainly at larger Murphy Express or Murphy USA travel-plaza sites, not at standard Supercenter canopies. If you need DEF while you fuel, plan on a 2.5-gallon jug from Auto Care.
- Do Walmart Neighborhood Markets have diesel?
- 258 of the 260 Neighborhood Markets with fuel that we track report a diesel price. Many Neighborhood Market forecourts are smaller Walmart-operated kiosks. Search by city or use near-me lookup and open the station page — if diesel is missing from the price list, that market does not sell it.
- Can I fill a truck or RV at a Walmart diesel pump?
- Walmart and Murphy USA kiosks are parking-lot retail pumps, not truck stops. Pickups, vans, and many travel trailers fit if you take an outer island and watch the posted canopy clearance. Full-size Class 8 tractors, oversized fifth wheels, and anything that needs a dedicated truck lane, high-speed DEF pump, or scale are better served at a purpose-built truck stop. There is no truck-parking or shower amenity at these sites.
- Does the Walmart+ fuel discount apply to diesel?
- Yes. The Walmart+ 10¢-per-gallon fuel benefit is billed as applying to every gallon of fuel at participating Walmart and Murphy USA pumps, including diesel. Redeem in the Walmart app (QR at Walmart-branded pumps; discount ID on the Murphy keypad). It does not stack with every other offer; check the Walmart+ gas discount guide for the fine print.
- Does Walmart sell diesel anti-gel or Diesel 911?
- Howes Diesel Treat, Diesel 911, and similar winter anti-gel bottles are sold in the Auto Care aisle, not as a separate pump grade. Most Walmart and Murphy locations sell a single ULSD diesel; winter operability in cold states is handled by the distributor blending cold-flow improver or #1 diesel into that tank from roughly November through March, not by a second nozzle.
