Petrol in a Diesel Hyundai Accent, and You've Driven It
The engine wants switching off then leaving off as soon as you can pull over somewhere safe, if you have driven with petrol in a diesel Hyundai Accent. Where you have pulled up, we can still sort it out, and damage that lasts is very rare when it's spotted early.
When Petrol in Diesel travels out to wherever your Hyundai Accent has stopped, the petrol is cleared out of the system and your fuel tank drained. Once we go, the car is back on fresh diesel.
Petrol in a diesel Accent: the signs to look for
You might go a couple of miles before spotting anything wrong, as petrol inside your fuel tank frequently leaves a diesel Accent driving as usual to begin with. People normally notice the following when there's petrol or AdBlue in the fuel tank:
- the motor lacks power, especially whenever you ask it to pull
- it runs rough, or your idle becomes uneven
- there's more smoke than normal from the tailpipe
- a warning light lights up
- the motor stalls then may not restart
If any of these started after you fuelled up, check your receipt to find out what went in.
What travelling does to wrong fuel in your Hyundai Accent
Till the engine draws it out, wrong fuel in your Hyundai Accent stays in your fuel tank, but driving draws it on to the fuel filter, and then into the injection pump and your injectors. Petrol dilutes the diesel fuel that protects your fuel pump and your fuel injectors as it runs through them, and running the Accent further brings the mix into more of your system.
This is the reason to stop as soon as you can rather than complete the journey. Driving a long way on contaminated fuel is what can cause harm, and if a car is stopped early, a drain and a clean are usually all it needs.
We come to where you've pulled up
Taking the Accent anywhere isn't needed. We come to it at the side of the road or outside your home, and so there's no need to start the car or arrange a recovery truck.
On a busy road, turn on the hazards, then choose somewhere safe to wait away from the traffic.
When you phone 0333 366 0103, tell us where you are, which Accent it is and about how far you travelled. Knowing the version from the badge, such as the Accent 1.5 CRDi, is useful as well.
Fuel drain on your Hyundai Accent when you have driven on it
Next to a drain at the forecourt, a fuel drain on your Hyundai Accent goes a step further after driving. We empty the tank first, then open the lines and then rinse them through with your filter, so no petrol is remaining between your tank and the engine. The fuel system is primed after clean diesel is in, and the engine is started to confirm it runs correctly.
AdBlue in a diesel Hyundai Accent once driven
Driving with AdBlue in a diesel Hyundai Accent usually brings warning lamps, smoke and uneven running, and the car may go on to stall. The pump picks up fuel from the base of the tank, which is where AdBlue settles, and so it gets to your fuel line fast. It also doesn't burn or lubricate. Its water drying out lets the urea form crystals in your fuel lines and the filter.
AdBlue removal from a diesel Hyundai Accent: what it involves
AdBlue removal from a diesel Hyundai Accent that has been run means draining the fuel tank and then flushing the crystals out of your fuel lines and the fuel filter, and we'll change your fuel filter if it needs it.
A dedicated AdBlue tank, if your Accent has one, is left as it is. The job is about liquid in your diesel tank, and doesn't involve removing or disabling an AdBlue system.

The cost of a fuel drain on the Hyundai Accent after a drive
The cost of a fuel drain on the Hyundai Accent after it's been driven depends largely on how far it went and where it has stopped, and whether it was petrol or AdBlue makes a difference as well. Phone with those details and we can explain what the job will involve.
Driven on petrol in a diesel Hyundai Accent: your questions
Has the petrol ruined my Accent?
It's very unlikely to be. If the vehicle is stopped early, draining and cleaning the system is what we do where you have pulled up, and damage that lasts is rare after that.
Can I drive the car home first?
We would sooner you didn't. Contaminated fuel reaches further into your fuel system with each mile, which means you can keep the Accent where it stands whilst we drain it there, with no reason to move it.
It has stalled and won't restart. What should I do?
Leaving it alone is better than trying again, since every try draws the blend further through. Once we have emptied and flushed it and put clean diesel in, we prime the fuel system and start it for you.
Insurance and wrong fuel in my Hyundai Accent: am I covered?
Misfuelling cover is offered in some policies, so check yours after the car has been sorted. Whatever it says, we still come out.
