Real-world MPG often falls short of EPA numbers. Your results depend on weather, traffic, and habits. Fast starts drop MPG by 10 to 20 percent. Stop-and-go traffic burns more fuel than steady highway runs. Underinflated tires or extra weight cut efficiency by 3 to 10 percent. Cold weather, short trips, and heavy AC use lower MPG. Skip maintenance like oil changes or air filter swaps, and MPG suffers more.
Boost MPG in either SUV with these steps:
- Check tire pressure monthly. Set it to the door sticker spec, usually 32 to 35 PSI.
- Drive smooth. Leave space for others. Coast to stops when safe.
- Use cruise control on highways. Keep speeds reasonable.
- Ditch roof racks and heavy loads when you can.
- Group errands to cut cold starts and idling.
- Stick to the maintenance schedule. Swap the air filter on time.
