Many 6.0 Powerstroke owners consider EGR deletion primarily for reliability, but the fuel economy improvements can be equally significant. Understanding the real-world 6.0 Powerstroke MPG after EGR delete results helps justify this modification both financially and practically. This comprehensive analysis examines actual mileage gains, factors affecting results, and what you can realistically expect from eliminating the problematic EGR system.
Documented MPG Improvements: Real Owner Results
City Driving Improvements
Owners report consistent 1-2 MPG gains in stop-and-go city driving after EGR delete due to:
- Reduced engine load from eliminated exhaust gas recirculation
- Cleaner combustion without diluted intake air
- Improved throttle response requiring less pedal input
- Eliminated regeneration cycles that consume extra fuel
Highway Driving Benefits
The most significant gains occur during highway cruising, with 2-4 MPG improvements commonly reported because of:
- Optimized air-fuel ratios for cleaner burning
- Reduced pumping losses from eliminated EGR flow
- Better thermal efficiency with proper combustion temperatures
- Aerodynamic benefits from cooler operating temperatures
Towing and Heavy Load MPG
Even under load, owners see 1-2 MPG improvements when towing thanks to:
- Lower EGT temperatures reducing energy waste
- More efficient power production per fuel unit
- Reduced need for downshifting on grades
- Better engine efficiency across the power band
Factors Affecting Your Actual MPG Gains

FAQs About 6.0 Powerstroke MPG After EGR Delete
Q1: How much can I expect my MPG to improve after EGR delete?
A1: Most 6.0 Powerstroke owners see 1-3 MPG improvements in city driving and 2-4 MPG gains on highway, with actual results depending on driving habits, vehicle condition, and supporting modifications.
Q2: How long does it take to see MPG improvements after EGR delete?
A2: MPG improvements are typically immediate after proper installation and tuning. However, it may take 1-2 tankfuls to establish accurate baseline comparisons and see consistent results.
Q3: Will EGR delete MPG improvements be permanent?
A3: Yes, the MPG improvements from EGR delete are permanent as long as the system remains properly maintained. The gains come from fundamental improvements in engine efficiency and reduced mechanical restrictions.
Q4: Do I need special tuning to get MPG benefits from EGR delete?
A4: While basic EGR delete will provide some MPG improvement, economy-optimized tuning will maximize your fuel efficiency gains by properly adjusting air-fuel ratios and transmission shifting patterns.
Q5: Can I still get good MPG with performance tuning after EGR delete?
A5: Yes, many performance tunes include economy-oriented driving modes that can provide both power when needed and excellent fuel efficiency during normal cruising conditions.
