On Friday 25 July, we invited Britain's 35 million motorists to pop the bonnet and check the oil level in their car. If everyone did it, it could save UK drivers a massive £300 million in repair bills.

If the oil looks low on the dipstick, you're almost certainly on the way to avoiding a breakdown by checking and topping up correctly; and if it looks about right, you can have peace of mind motoring - for the time being.

Best of all it only takes a minute and it could save you a fortune.
