The Comdata Math at TA Petro
The 40-cent Comdata discount is the biggest per-gallon saving available at any major truck-stop chain. Here's what it means in practice:
| Gallons per fill | Cash cost | With Comdata (40c off) | Savings |
|---|---|---|---|
| 100 gal | $563.00 | $523.00 | $40.00 |
| 150 gal | $844.50 | $784.50 | $60.00 |
| 200 gal | $1126.00 | $1046.00 | $80.00 |
| 300 gal | $1689.00 | $1569.00 | $120.00 |
Based on $5.63 cash price and 40c/gal Comdata discount. Actual prices vary by location.
Does Comdata really save 40 cents per gallon at TA Petro? +
Yes. Comdata's published discount at TA Petro (Travel Centers of America) is up to 40 cents per gallon off the cash diesel price, making it the most generous per-gallon fleet card discount available at any national chain. At 100 gallons, that's $40 saved per fill; at 150 gallons, $60. The actual discount can vary by location and time, but the published rate is 40 cents/gal. 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.
What is TA Petro's UltraONE program? +
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.
Why is TA Petro's cash price higher than Pilot or Love's? +
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.
