Petrol in a Diesel Hyundai Grand Santa Fe, and You've Driven It
If you have driven with petrol in a diesel Hyundai Grand Santa Fe, stop once it's safe, turn the motor off and keep it off. Spotted soon, it very rarely leaves permanent damage, and sorting it out wherever you have stopped is still something we can do.
Wherever your Hyundai Grand Santa Fe has ended up, Petrol in Diesel travels out to empty the fuel tank there and clean the petrol out of the system. We leave when it's running again on clean diesel.
Spotting petrol in a diesel Grand Santa Fe
To begin with, petrol in the tank often makes little difference to how a diesel Grand Santa Fe drives, so the symptoms appear a few miles later on. The following are the ones most often spotted if your tank has AdBlue or petrol in it:
- power falls away, particularly as you ask the motor to accelerate
- it runs rough, or your idle turns erratic
- the exhaust puts out more smoke than normal
- the dash shows warning lamps
- it cuts out and might not restart
Your receipt will show what was put in, which means you should look at it if one of these started after you fuelled up.
Wrong fuel in your Hyundai Grand Santa Fe and the effect of travelling on it
The tank holds wrong fuel in your Hyundai Grand Santa Fe in one place till it is drawn out by the engine. After you drive, it goes through your fuel injectors, the fuel filter and your high-pressure fuel pump. As diesel runs through your fuel injectors and your fuel pump it lubricates them, yet petrol dilutes it, and that is why the Grand Santa Fe takes that mixture further into the fuel system the further it is used.
That is the reason to stop the moment you can rather than complete the journey. Driving a long way on tainted fuel is what can do damage, and if a motor is stopped early, a drain and a clean are normally all it needs.
Just where you stopped
The Grand Santa Fe does not need taking anywhere. You can leave it at the side of the road or at home while we come to it, with no restart and no tow to arrange.
With your hazard lights on, stand away from the traffic somewhere safe when the road beside you is fast.
When you phone 0333 366 0103, tell us where you are, which Grand Santa Fe it is and about how far you drove. Knowing the version on the badge, like the Grand Santa Fe 2.2 CRDi 4WD, helps too.
Fuel drain on your Hyundai Grand Santa Fe after it has been driven
A fuel drain on your Hyundai Grand Santa Fe after it was driven goes a step further than a drain at the forecourt. No petrol is remaining between your tank and the engine afterwards, so your fuel tank is drained first and the fuel lines are then opened and rinsed through with your fuel filter. Fresh diesel goes in, the fuel system is primed, and we start the engine to confirm it runs correctly.
AdBlue in a diesel Hyundai Grand Santa Fe once driven
Travelling with AdBlue in a diesel Hyundai Grand Santa Fe usually brings warning lights, smoke and uneven running, and your car might stall. AdBlue does not burn or lubricate, and it settles to the base of your fuel tank where your fuel pump picks up fuel, and so it reaches the fuel line fast. As its water dries out, the urea crystallises in your lines and the fuel filter.
AdBlue removal from a diesel Hyundai Grand Santa Fe: what it means
AdBlue removal from a diesel Hyundai Grand Santa Fe that has been run means emptying your fuel tank and then clearing the crystals out of your fuel lines and your fuel filter, and we'll replace your fuel filter if it needs it.
Just the diesel tank is dealt with here. If your Grand Santa Fe has an AdBlue tank of its own, it is left alone, and nothing here means taking out or switching off the AdBlue system.

What a fuel drain on the Hyundai Grand Santa Fe costs after a drive

Usual queries about petrol in a diesel Hyundai Grand Santa Fe after a drive
Has the petrol ruined my Grand Santa Fe?
Very probably not. With the car stopped soon and the fuel system emptied and flushed where you've stopped, which is what we do, lasting harm is rare.
Can I make the drive home first?
Our advice would be not to. Every mile on contaminated fuel carries it further through the system, and we can drain the Grand Santa Fe where it stands, which means there is no need to shift the car.
It will not restart after stalling. What now?
Leaving it alone is wiser than trying again, as each try pulls the mixture further through. We prime your fuel system and start it for you once it's been drained and rinsed and clean diesel is in.
Wrong fuel in my Hyundai Grand Santa Fe: will insurance cover it?
Some policies offer misfuelling cover, and so it's worth looking at yours once the vehicle is dealt with. We come out either way.
