Not sure if you've misfuelled? These are the tell-tale signs — and what to do the moment you suspect it.

## The warning signs
Hard starting, misfiring, loss of power, clouds of smoke, a strong fuel smell, and warning lights soon after filling up. The clearest clue of all is your receipt and the pump you used.

## When in doubt, don't drive
If you even suspect a misfuel, don't start the engine — treat it as wrong fuel until proven otherwise. It's far cheaper to check than to run it.
