Kept Driving With Petrol in a Diesel Renault Megane?
Keeping the motor off is what counts after you've travelled on petrol in a diesel Renault Megane, which means you should stop as soon as it's safe and turn the motor off. It is very rare for permanent harm to result if it's caught soon, and it can still be sorted out wherever you've stopped.
Petrol in Diesel travels out to wherever your Renault Megane has ended up, empties the tank and cleans the petrol from your fuel system. Once we head off, the car is running on fresh diesel.
Petrol in a diesel Megane: the symptoms to watch for
A diesel Megane with petrol inside your fuel tank frequently feels normal at first, so the signs tend to appear a few miles later on. With petrol or AdBlue in the tank, the following are the ones drivers usually notice:
- the motor loses power, particularly whenever you ask it to pull
- it runs rough, or the idle gets erratic
- the tailpipe gives off more smoke than normal
- a warning light comes on
- after it stalls, it might not restart
One of these beginning after you filled up is reason enough to check your receipt to see what went in.
How far wrong fuel in your Renault Megane gets once you drive
Wrong fuel in your Renault Megane stays in your tank till the engine draws it out, and driving is what takes it through your fuel filter, the high-pressure pump and your injectors. Diesel lubricates your fuel pump and the fuel injectors as it passes through them and petrol weakens it, and so the farther the Megane is taken, the more of your fuel system that mixture gets to.
This is the reason to stop the moment you can rather than complete the trip. Normally, a drain and a clean are all a car needs if it's stopped early, because what can do harm is driving far on fuel that is tainted.
Whether yours is the Megane dCi 160 FAP or another version of the Megane, nothing is different.
Staying where you have stopped
Moving the Megane anywhere is not needed. We come to it at the side of the road or outside your house, so there is no need to start it or book a tow.
If you're beside a main road, switch your hazard lights on and wait somewhere out of harm's way, clear of the traffic.
Roughly how far you went, which Megane it is and where you have pulled up are what to mention when you ring 0333 366 0103. The version shown on the badge, like the Megane Classic 1.9 dCi, is useful as well.
A fuel drain on your Renault Megane after a drive
After it has been driven, a fuel drain on your Renault Megane takes one step more than a drain on the forecourt. No petrol is remaining between your tank and the motor afterwards, so your tank is emptied first and the lines are then opened up and flushed through with your fuel filter. The fuel system is primed after fresh diesel is in, then the engine is started to confirm it runs correctly.
After it's run: AdBlue in a diesel Renault Megane
Uneven running, smoke and warning lights are the usual signs after you have driven on AdBlue in a diesel Renault Megane, and the vehicle might then stall. Sinking to the bottom of the tank, where your pump picks up fuel, AdBlue gets into the fuel line quickly, and it does not burn or lubricate. The urea forms crystals in your filter and the lines as its water evaporates.
How AdBlue removal from a diesel Renault Megane is done
We replace your fuel filter if it needs it during AdBlue removal from a diesel Renault Megane after it has run, when the tank is drained and the crystals are cleared from the filter and your fuel lines.
Nothing here involves disabling or removing the AdBlue system. It deals with fluid in your diesel tank, and any dedicated AdBlue tank your Megane has is left alone.
The Renault Megane fuel tank capacity and the engines
60 litres is the capacity of the diesel tank on each version of the Renault Megane in our figures.
You'll see dCi and DTI badging on diesel Megane versions.
One of them labelled DTI rather than dCi is the Megane Classic 1.9 dTi.
The Megane Grandtour 2.0 dCi has the biggest engine at 2.0 litres, and the Megane 1.5 dCi has the smallest, at 1.5 litres.
Amongst them are Coupe and Cabriolet versions.

Fuel drain on the Renault Megane after driving: the cost
The cost of a fuel drain on the Renault Megane after it has been driven hinges mainly on how far it went and where it has stopped, and whether it was petrol or AdBlue makes a difference too. We can explain what the work will need once you phone with those details.
Common questions about petrol in a diesel Renault Megane after driving
Has the petrol ruined my Megane?
Very probably not. With the vehicle stopped soon and the system drained and flushed where you have stopped, which is what we do, lasting damage is rare.
Is it all right to drive it home first?
Our advice would be not to. We can drain the Megane just where it is, so it does not need shifting, and every mile driven on tainted fuel would push it further through your fuel system.
What do I do if it has stalled and won't restart?
Trying again draws more of the blend through with each attempt. Please leave it as it is. We start it for you after emptying and flushing it, putting clean diesel in and priming the system.
Which Megane I have: does it matter?
There are 52 diesel versions of the Megane, and the badge on the boot shows which one you have. Knowing that assists us when you ring.
Insurance and wrong fuel in my Renault Megane: am I covered?
Some insurance policies include misfuelling cover, so it's worth checking yours after the vehicle is dealt with. We still come out either way.
