TA Petro Diesel Price in 2026: $5.62 Cash, Comdata Saves $0.40/gal, ~280 Locations

Largely yes, with caveats. Comdata's advertised discount at TA Petro (Travel Centers of America) is up to 40 cents per gallon off the cash diesel price on its Total Advantage product, and up to 50 cents on Comdata Max - the most generous per-gallon fleet card discount available at any national chain. At 40 cents on 100 gallons, that's $40 saved per fill; at 150 gallons, $60. Two things matter: these advertised rates apply to fleets of 20 or fewer trucks (larger fleets negotiate custom pricing), and the saving is delivered through cost-plus pricing tied to the local wholesale rack rate, so the actual cents-off varies by location and week. Still, this is why OTR truckers with Comdata often prefer TA Petro over other chains even when TA's cash price is a few cents higher.

UltraONE is TA Petro's professional driver loyalty program. It earns points for diesel purchases, shower purchases, restaurant visits, and merchandise. Points can be redeemed for free showers, parking, merchandise, and fuel credits. The UltraONE Gold tier (earned at higher annual fuel volume) includes priority shower access and additional point multipliers. UltraONE works in addition to fleet card discounts - so a Comdata holder who also has UltraONE gets the 40-cent fleet discount plus loyalty points.

TA Petro's cash retail diesel is typically $0.02-$0.05/gal above Pilot and Love's. This is partly because TA Petro's business model is more oriented toward fleet drivers with cards (who get the 40-cent Comdata discount) rather than cash-paying retail customers. The posted cash price matters less to TA's core customer because most professional drivers are using fleet cards. TA also invests more heavily in per-location amenities (Iron Skillet/Country Pride full-service restaurants, premium shower suites) which is reflected in slightly higher cash prices.
