AMBEST is a network of independent, family-owned truck stops that offers a fleet fuel card designed for trucking companies looking to save on diesel while maintaining control over fuel spend. The card runs on the EFS network, giving you access to 16,000 fuel stations nationwide in addition to AMBEST locations, though the discounts are found at AMBEST truck stops.
AMBEST offers two card options with different pricing structures:
Both AMBEST cards include controls and reporting tools through the EFS platform. Fleet managers can set purchase limits, restrict fueling locations, require driver prompts, and monitor transactions through detailed reports, helping improve visibility and reduce misuse.
The AMBEST fuel card runs on the EFS network and is accepted at 16,000 fuel stations nationwide. About 500 of those are AMBEST network locations, where you’ll get fuel discounts. Use the links below to find accepting locations.
The AMBEST Preferred card offers average discounts of 51¢ per gallon at 500 in-network locations. The AMBEST Direct card provides custom discounts based on the stations your fleet uses most.
| AMBEST Direct | AMBEST Preferred | |
| Discount at AMBEST locations | Custom discounts | Average 51¢ per gallon |
The AMBEST Direct card has a higher monthly fee, but no transaction fees at AMBEST locations, while the AMBEST Preferred card has a lower monthly fee but does charge a transaction fee at those locations. If your fleet is making more than 33 transactions per month at AMBEST locations, the Direct card is the better value since avoiding paying transaction fees outweighs that additional monthly fee.
| Fee | AMBEST Direct | AMBEST Preferred |
| Monthly fee | $55.99 per account | $7.95 per account |
| Account setup fee | $50 | $75 |
| In-network transaction fee | $0 | $1.50 per transaction |
| Out-of-network transaction fee | $1.75 | $1.50 per transaction |
| Late fee | 6.99% | 6.99% |
