Did You Put AdBlue in the Wrong Tank?

by | Apr 24, 2017 | Fuel Advice | 0 comments

Diesel exhaust fluid, better known as AdBlue, is used in some modern diesel vehicles to reduce the nitrous oxide level in their fuel emissions. It’s often called a fuel additive – but that’s far from the truth.

Fuelling Mistakes in AdBlue Ready Vehicles

AdBlue has its own small ‘tank’, usually with a blue fill cap next to the black, red, or green of your diesel fill cap – but in many vehicles the two caps are very close together, certainly close enough for muscle memory to kick in and for AdBlue to end up in your diesel tank by accident.

The good news is that the reverse almost never happens; the AdBlue cap is too small for standard diesel nozzles to fit, so even acting on autopilot, you should catch yourself ahead of time.

Why AdBlue isn’t an Additive

The AdBlue tank is made from non-typical fuel tank materials due to the chemical’s corrosive nature. Your AdBlue tank will be perfectly safe, but if it gets into your diesel tank it can corrode pipework and components, damaging cast iron, zinc, brass, aluminium and steel with equal aplomb.

What to Do When You Have AdBlue in your Diesel Tank

Don’t start your car! If you didn’t realise immediately and have driven off, get off the road as quickly as possible, but if you’re still on the filling station forecourt, don’t leave it.

Driving off – even directly to a garage for repairs – will do more damage and just increase your potential bill.
