Fuel is our biggest expense as owner operators. After tracking every fill-up for the past two years, here’s what’s actually moved the needle on my MPG and costs.
Driving Habits That Save Fuel
- Progressive shifting - let the engine do the work
- Cruise control on flat highways saves more than you think
- Coast to red lights instead of braking hard
- Keep RPMs in the sweet spot (usually 1200-1400 for most engines)
- Slow down - the difference between 65 and 75 mph is huge on fuel consumption
Maintenance That Matters
- Keep tires properly inflated - check weekly, not monthly
- Clean air filters regularly (I check mine every 15k miles)
- Fuel filters changed on schedule
- Proper wheel alignment saves fuel AND tires
- Don’t ignore that check engine light
Route Planning
- Use trucker GPS that accounts for truck routes and fuel stops
- Plan fuel stops based on price, not convenience
- Apps like GasBuddy, Trucker Path show real-time diesel prices
- Sometimes the longer route with lower elevation gains saves fuel
Fuel Card Strategies
- Stack discounts when possible (fuel card + loyalty programs)
- Some cards offer better discounts at specific chains
- Track your per-gallon savings monthly
- Compare cards annually - deals change
Idle Reduction
- APUs pay for themselves in fuel savings
- Shore power when available
- Plan stops at truck stops with amenities to reduce idle time
- Proper insulation helps maintain cab temp longer
