Roof Boxes Drain Your Fuel | Sheffield News

With August bank holidays looming, drivers beware: that empty roof box on your car could slash your fuel efficiency by up to 25%. Even without cargo, the added drag forces your engine to work harder—especially at highway speeds. Larger boxes (600L+) hit harder than compact ones, and fuel prices are already sky-high, with petrol near £90 and diesel hitting £100 per tank. The fix? Slow down from 70 to 60 mph on the motorway—cutting fuel use by 15-20%. Before you hit the road, ask: do you really need that box? Small tweaks can save big bucks.
