SUE’S TIPS:

◆ If your boot is full of junk, you’re wasting money and precious fuel. Clear it out and just keep the essentials in there.

◆ Check tyre pressures. Under-inflated tyres mean your engine has to work harder. Pop your registration into TYRESAFE.ORG to check the correct pressure.

◆ Don’t drive until you’re empty. If you’re caught short, you can pay over the odds on fuel, especially at motorway services.
