💡 Proven Ways to Improve Real-World Gas Mileage
🎯 Maintain Factory Tire Pressure
Underinflated tires by just 4 to 5 PSI increase rolling resistance and can degrade fuel efficiency by up to 2% to 3% over a standard commute cycle.
🚀 Moderate Highway Cruising Speed
Aerodynamic drag rises exponentially above 65 MPH. Cruising at 65 MPH instead of 75-80 MPH can save up to 10% to 15% in highway fuel consumption.
⛽ Correct Octane Grade
Always verify whether your vehicle requires Premium or Regular fuel. Running high octane in an engine tuned for 87 provides zero MPG benefit.
📦 Eliminate Idle & Cargo Weight
Every extra 100 lbs of dead cargo weight reduces gas mileage by roughly 1%. Avoid prolonged idling, which consumes 0.2 to 0.5 gallons per hour.
