Diesel fuel often comes with higher prices than gasoline, but it’s essential for trucks, RVs, and heavy-duty vehicles that rely on torque and efficiency. The good news is that with the right strategies, diesel drivers can still find plenty of ways to save at the pump. Here’s how to cut diesel fuel costs effectively.

1. Use Diesel Price Tracking Apps
   Apps like GasBuddy and Trucker Path allow you to locate the cheapest diesel fuel prices along your route.

• GasBuddy includes diesel pricing filters.

• Trucker Path is specifically designed for commercial drivers and often lists truck stop amenities alongside diesel prices.

2. Join Diesel-Specific Reward Programs
   Many fuel brands offer loyalty programs tailored for diesel users:

• Pilot Flying J MyRewards program offers fuel discounts and shower credits.

• Love’s My Love Rewards gives points for every gallon of diesel purchased.

• TA Petro UltraONE Rewards focuses on long-haul trucking discounts.

3. Plan Routes Around Truck Stops
   Truck stops often have the most competitive diesel prices, plus amenities like easy access for larger vehicles, RV-specific parking, and multi-pump diesel lanes.

• Look for major chains like Pilot Flying J, Love’s Travel Stops, and TA Petro Travel Centers.

4. Use Fuel Cards for Commercial Drivers and RV Owners
   Some fuel cards offer wholesale diesel pricing:

• EFS Fuel Card

• TSD Logistics Open Road Diesel Discount Program
  These programs are great for independent truckers, RV owners, and commercial fleets.

5. Maintain Proper Tire Pressure and Load Weight
   Diesel fuel economy is heavily influenced by tire pressure and cargo load:

• Keep tires properly inflated based on manufacturer specifications.

• Avoid carrying unnecessary weight in your truck bed or RV.

6. Drive at Optimal Speeds
   Fuel efficiency for diesel engines peaks at moderate, steady speeds—typically between 55 and 65 mph. Driving faster increases wind resistance and fuel consumption.
7. Limit Engine Idling
   Diesel engines use significant fuel while idling. Many newer trucks come equipped with idle reduction technology, but if yours does not, avoid unnecessary idling when parked.
8. Shop Around for Diesel at Big Retailers
   Some warehouse clubs like Costco and select Walmart locations offer diesel at competitive prices.

• Always check ahead of time if diesel is offered, as not all Costco or Walmart fuel stations have it.

9. Leverage Cashback Apps Carefully
   While diesel is less commonly included in general cashback promotions, always check apps like Upside or Ibotta for targeted diesel cashback offers when available.
10. Fill Up During Off-Peak Hours
    Fuel deliveries often happen early in the morning or overnight, so filling up during off-peak hours can sometimes help avoid price surges tied to daily demand.

Key Takeaway:
Diesel drivers face unique challenges with higher fuel costs, but by using rewards programs, planning routes strategically, maintaining your vehicle properly, and tracking prices with smart apps, you can consistently save money on the road—whether you are hauling freight or exploring the country in an RV.
