Mercedes are wonderful cars to drive, but nobody ever accused them of being fuel-efficient. There are some practical steps you can take to improve the miles per gallon (MPG) your Mercedes gives you, however. By following these five practical tips, you’ll reduce your fuel use and avoid wasting money at the petrol pump.


1. Weight

The more weight you carry, the more power it takes to move the car. That extra power takes fuel, reducing the miles per gallon your Mercedes gets and costing you money. Studies show that for every extra 50kg you carry, your fuel efficiency drops by 1%. That might not seem like a lot, but if you’re carrying items around needlessly, in your boot for example, then it’s reducing your car’s performance. Small differences like this add up over the course of many miles.

2. Drive Sensibly

It’s fun to put your foot down every now and then, but it’s also expensive if it becomes a habit. Every 10 mph you go above 55 drops your fuel efficiency by up to 15%. The faster you go, the more power is wasted each time you need to brake. This can add up to a lot of wasted fuel. The best thing you can do to improve your MPG is to stay within the speed limit and avoid unnecessary braking.

3. Keep Your Tires Firm

Underinflated tires are doubly bad for fuel efficiency. A drop of 10 psi in tire pressure can lower your MPG by 1.3 on its own. But the extra friction also makes the engine work harder to increase the car’s speed, which wastes fuel needlessly every time you hit the accelerator.

4. Keep Your Car Well Maintained

Any blockages that interfere with the fuel flow or ignition make the engine work less efficiently. Regular maintenance will help you to avoid such problems.

5. Avoid Idling

Keeping the engine running while your car sits still wastes fuel and reduces your MPG. Turning the engine off while you wait for a passenger, or sit hopelessly gridlocked, will save a little bit of fuel each time.

The best way to increase the miles per gallon of your Mercedes Benz is to follow tried and true advice:
  • Drive smoothly, without excessive speed or braking
  • Avoid carrying extra weight
  • Don’t leave the engine running needlessly
  • Keep the car well maintained.
A few small changes can make a big difference to your car’s fuel efficiency.
