Already Driven With Petrol in a Diesel Mitsubishi ASX?
Leaving the motor off is what matters after you have travelled on petrol in a diesel Mitsubishi ASX, which means you should stop as soon as it is safe and then switch the motor off. Where you've pulled up, we can still put it right, and damage that lasts is very uncommon when it is spotted early.
Wherever your Mitsubishi ASX has ended up, Petrol in Diesel travels out to drain your tank there and clear the petrol from your fuel system. Once we go, the vehicle is running on fresh diesel.
Petrol in a diesel ASX: the signs to look for
To begin with, petrol in the fuel tank frequently changes very little to how a diesel ASX drives, and the symptoms show up a few miles later on. Whether your fuel tank has petrol or AdBlue in it, drivers normally spot the following:
- the engine lacks power, especially whenever you ask it to pull
- lumpy running, or an uneven idle
- there's more smoke than usual from the tailpipe
- dashboard warning lights show
- it stalls and might not start again
One of these starting after you filled up is reason enough to look at the receipt and see what was put in.
Wrong fuel in your Mitsubishi ASX: what travelling on it does
The tank keeps wrong fuel in your Mitsubishi ASX where it is till it's drawn out by the engine. Once the car is driven, it goes through your injectors, the fuel filter and your injection pump. Petrol dilutes the diesel fuel that lubricates your pump and your injectors as it runs through them, and driving the ASX further brings that mix into more of your system.
That's why it's wiser to stop as soon as you can than to complete the trip. Damage, where it occurs, comes from a long drive on tainted fuel, and a drain and a clean are normally all a car requires when it's stopped soon.
Another version of the ASX is no different from the ASX 1.8 DI-D 4WD here, and so which version is yours makes no difference.
Where you have pulled up
There's no reason to move the ASX anywhere. No recovery truck has to be booked and there's no reason to restart it, because we come to it at the roadside or outside your home.
If you're beside a busy road, turn your hazards on and wait somewhere safe, away from the traffic.
Before you ring 0333 366 0103, have your location to hand, along with the mileage you drove and which ASX it is. It helps too when the badge shows the version, like the ASX 1.8 DI-D 2WD.
Fuel drain on your Mitsubishi ASX after it has been driven
A fuel drain on your Mitsubishi ASX after it was driven goes a step further than one on the forecourt. Draining the tank comes first. Then we open the fuel lines and rinse them through with the filter, so there is no petrol left between the fuel tank and the engine. With fresh diesel in and the fuel system primed, we start the motor then check it runs correctly.
AdBlue in a diesel Mitsubishi ASX after it has run
Rough running, smoke and warning lights are the usual symptoms once you have driven on AdBlue in a diesel Mitsubishi ASX, and the vehicle might stall. Because AdBlue sinks to the base of your tank, where the fuel pump draws its fuel, it is in your fuel line fast, and it neither burns nor lubricates. As its water dries, the urea forms crystals in your lines and your fuel filter.
AdBlue removal from a diesel Mitsubishi ASX after driving
AdBlue removal from a diesel Mitsubishi ASX that has been run means emptying your tank and then clearing the crystals out of your fuel lines and your filter, and we'll replace your fuel filter if it needs it.
If your ASX has a dedicated AdBlue tank, that is not touched. This is about fluid in your diesel tank, not removing or turning off the AdBlue system.

Questions after driving with petrol in a diesel Mitsubishi ASX
Is the ASX ruined now?
Almost certainly not. With the vehicle stopped soon and the system emptied and cleaned where you've pulled up, which is what we do, lasting damage is rare.
Is it OK to drive it home first?
Our advice would be not to. Contaminated fuel gets further into your fuel system with every mile, which means you can keep the ASX where it stands whilst we empty it there, with no need to shift the vehicle.
What do I do if it has stalled and won't restart?
Leaving it alone is better than trying again, as every attempt pulls that mixture further through. With it drained and flushed and clean diesel in, we prime the fuel system and get it started for you.
Does the version of my ASX make a difference?
There are 2 diesel versions of the ASX, and the badge on the boot shows which one you have. Knowing that helps us when you ring.
Is wrong fuel in my Mitsubishi ASX covered by insurance?
Some policies have misfuelling cover, and so it's worth looking at yours after your car is sorted out. We come out either way.
