🚗 How to Get the Best Mileage from Your Large SUV

Just because you’ve got a big ride doesn’t mean you have to burn big fuel. 🔥⛽
Here are smart, real-world tips to squeeze the most miles from every gallon — no matter what SUV you drive:

✅ 1. Use ECO Mode

Most modern SUVs come with an ECO or fuel-saver mode — turn it on.
It adjusts throttle and transmission to reduce fuel burn.

✅ 2. Keep Tires Properly Inflated

Low tire pressure = more drag = more fuel used.
Check tire pressure every 2 weeks for best MPG.

✅ 3. Lighten the Load

Remove that roof rack or unused gear from the trunk.
Every extra 100 lbs can reduce mileage by 1–2 MPG.

✅ 4. Avoid Aggressive Driving

Quick starts and hard braking kill mileage.
Drive smooth, brake easy = save fuel and stress.

✅ 5. Stick to the Speed Limit

Fuel efficiency drops after 65 mph.
Cruise at moderate speeds for max savings.

✅ 6. Use Cruise Control on Highways

Smooth speed = better mileage.
Use cruise control to avoid speed spikes.

✅ 7. Don’t Idle Too Long

Modern engines don’t need warm-ups.
Idling more than 1 minute = wasting fuel.

🚀 Bonus Tip:

Get regular engine checkups.
A clean air filter and proper oil change can improve MPG by up to 10%!
