Petrol in Diesel

Put Petrol in a Diesel Car in Wombourne? Don't Start It

Do not start the engine. If the petrol is still sitting in the tank and your engine has not been started, a drain is nearly always all it needs — and that's settled in the coming few minutes, not by how much got in. Petrol in Diesel drains and flushes wrongly fuelled cars where they are, all over Wombourne and the rest of Staffordshire, on the forecourt, by the roadside or on a driveway. Ring us so our engineers can show you what happens after that before you attempt much else.

What now? Petrol in a diesel, in turn

  • Do not fire it up — and do not believe it if it does start. Here is the part motorists get wrong about petrol in a diesel in particular. A petrol engine given diesel typically just cannot run, and so the person stops and the wear stops with them. A diesel filled with petrol usually starts, ticks over and drives off perfectly well for a couple of miles. It isn't all right. It is grinding that fuel system whenever you drive.
  • Two tasks, diesel: it ignites, and on the way through it keeps the high-pressure fuel pump and injectors lubricated. Petrol only handles the one. Which is why your ignition stays off too — turn it on and you often prime your system, and that is petrol leaving your tank for exactly those parts.
  • Do not pour diesel on top to water down it. A diesel fuel system does not tolerate petrol by percentage the way that advice implies, and topping up removes nothing — it simply gives you a bigger tank of the same blend. The type makes no difference either: super unleaded is still petrol.
  • Wait where you are if you sensibly can. A vehicle that hasn't moved is the simplest one to deal with, and our team would sooner come to a tricky place than have it started. If you are stopped on the verge on Clap Gate Lane, put the hazards on and keep it there.
  • Get your position ready before you ring. A postcode beginning WV5 0 and whatever is next to you with a sign on it is the difference between our van showing up and the van circling.
  • Dial 0333 366 0103. Tell us what was put in, approximately how many litres, and also whether the motor has run. Those three replies decide the entire visit.

Quarter past eight, a fast top-up on the road in, and you realise close to eleven — by then the diesel Volkswagen Passat has been sitting outside Coseley for three hours. Phone us and keep the car right where it sits. The trip in is the bit that counts now, because diesel performs two jobs on its way through a motor: it ignites, and before it ignites it protects the high-pressure pump and its injectors. Petrol manages the first and not the second. So those couple of miles were travelled with the pump running on a liquid that had given up a lot of the protection it is built around — which is why the question we ask is how many miles you travelled, not how long your motor has been standing.

Diesel Renault Clio. A couple of litres of unleaded. Driven a couple of miles. Switched off now, outside Sainsbury's. That is the enquiry our engineers like, as the question under it's about amount through your pump instead of hours on the clock.

Hazards on. Engine off. Call us. It's twenty to nine by St Bernadette's Catholic Primary School, you're late, and the till receipt reads unleaded — and even though three miles in your BMW 3 Series sounds like nothing, fuel gets delivered on demand, and a frantic drive asks for plenty of it.

The pump sits before the injectors, and so whatever a worn-out one loses travels onward with your fuel — which is why we are direct about not driving on. Ring us, and leave your diesel Peugeot 3008 where it is near Church of the Venerable Bede.

Hire car or company car? Ring them before you phone us — some agreements want the hire firm to authorise the work, and sorting that out first is a great deal faster than sorting it after that. Then ring us about the Ford Kuga by Wombourne Leisure Centre, and don't worry that you cannot say how full your tank was. Nearly nobody can, in a vehicle they picked up two days ago, and we work it out there. The reason our technicians ask is that petrol in a diesel does its damage as a ratio: the same few litres in an almost empty tank is a far stronger blend than in a full one. Petrol is rated on how well it resists igniting under pressure, which is the opposite of what a diesel needs — so the stronger that mix, the more it rattles, smokes and goes flat.

Mobile fuel drain van at a diesel car in Wombourne

Draining petrol from the diesel on a forecourt

A large portion of the job ends up finished at a forecourt, because that's where it often kicks off. The drain typically happens there and then. Still on the forecourt at Texaco? Given the station's agreement, that's a spot our technicians work, and routinely.

Before the motor has started — the forecourt is the one place the mistake ends up halted. Our technicians can still put it right where it stands, even away from the pumps. In a car park, on a private drive or in a lay-by, the vehicle has been fired up and driven there, and that pulled fuel through the filter then into the high-pressure fuel pump, all the way from your tank. None of that is a disaster, although the flush then has to go past your tank to your lines and the filter, and the few seconds between seeing the till receipt and reaching for the keys are what decide that.

Attendants will generally pitch in pushing it away from the pump, which lets the next motorist get by. Accept the offer. Four vehicle lengths is not worth a start.

Coverage near Wombourne

Giggetty, Ounsdale, Brickbridge, Blakeley, The Bratch — every one of these on the runs that bring us across to Wombourne as well, a small village.

Not on this list? It tells you nothing. The places above are only the closest few, and nearly all towns in Staffordshire have a page of their own somewhere on our site. Near the border, or somewhere a satnav misreads? Call us and ask instead of guessing.

See this map for the patch shown on this page. Your car does not need to come to us. We work across every bit of it — kerbside, forecourts, driveways, car parks.

Stopped by the kerbside anywhere around Wombourne?

Not everybody gets a suitable spot to stop. If you realised after setting off and ended up on the verge on Giggetty Lane, or in a lay-by somewhere with the hazards going, that is a routine call for us instead of an unusual one.

Okay there? Sit by it. Not safe? Get out and clear of it. It will often oblige. A diesel running on petrol limps along very willingly, and that is the catch: restart it to reach somewhere better and the mixture goes further into the system with every mile driven. We will take the van to a tricky location without any fuss, and for your car that is far better than pressing on.

Driven it already? Stop, and check below

Here is where the M54 comes into it — under 10 miles from Wombourne. It will frequently take you onto it, and some way along, before you notice a thing. Then it's some smoke, an uneven idle and power falling away — not a clean stop. Wrongly fuelled diesels seldom give you one of those.

Do not restart it to move it. Pull off at the next sensible junction then turn off. Long trip? Anything approaching the under 5 miles to the closest city and you should presume the lot — filter, pump, injectors, all of that reached by the petrol. Say that on the call, since it affects what goes in our van.

All about Wombourne

Wombourne is a locality in southern Staffordshire, situated on the riverside near the town of Wolverhampton. Wombourne sits at an elevation of 79 metres, surrounded by nearby places such as Giggetty, Ounsdale, and Brickbridge. Wombourne has a population of approximately 3671 residents, predominantly living in semi-detached housing.

Our job in Wombourne, step by step

  • We check what got in, how much, and if the motor has run. The replies shape the work, which is why our engineers ask before giving a price.
  • The tainted mixture is drawn out of the tank.
  • Lines cleaned, filter cleared. Whatever remains later on isn't the thing that started the trouble.
  • We pour fresh diesel in and bleed your system.
  • It is run with new diesel in it, and our technicians check that it's running smoothly.

After that it is ready to drive away. Long-term damage is very unusual when it has been spotted early, and as everything is done where your car is, it never has to be taken to a workshop.

Wombourne AdBlue removal is a separate problem

Never crank it: that first instruction holds whether what went in was AdBlue or petrol. What differs is this problem itself. Petrol dilutes the diesel and removes the lubrication the fuel system relies on. AdBlue? Urea dissolved in water. Put that in with your diesel and you get rust instead, plus deposits.

Often the more serious of the two, AdBlue — and the details lives on its own Wombourne page. Both are ours to handle.

Budgeting for a petrol-in-diesel fuel drain around Wombourne

We cannot put one number on this page honestly, as the job is not one job. What shifts it:

  • Has it been started or driven? Nothing else counts for as much.
  • The tank's capacity, set against how much of the wrong fuel got into it.
  • Whether it's unleaded or AdBlue.
  • Where your car is, and if our van can sensibly reach and work on it.

Tell us what the vehicle is, how much got in, and if your motor has run. A clear answer comes back, not a range. If it isn't urgent — the car is at home and going nowhere — works too.

Petrol in diesel questions from Wombourne drivers

Fuel drains on a Wombourne petrol station forecourt

Yes — forecourts are where a large portion of this gets done. Regularly, provided the site agrees: Morrisons, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that location is something our engineers answer on the spot.

A couple of litres of petrol in a diesel — too much?

It hinges on the proportion rather than the litres, and a lot more on whether the engine has run. Five litres in a nearly empty tank is a separate case from five in a full one — but either way, the thing that determines how much work is required is whether that mix has been pulled through the fuel system.

I put petrol in my diesel and drove the vehicle. What next?

Stop somewhere sensible, turn off, then leave the car off. It is salvageable a lot more frequently than people fear, even though driving is what moves the problem from the tank into the pump and injectors — and the single most useful thing you can do now is not restart it.

Will a fuel drain void my warranty?

A drain then flush carried out correctly is not a change and does not void a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing likelier to cause an argument with one.

Could I put some two-stroke in and just drive?

What petrol has thinned isn't put back by two-stroke oil, which is an old fix for a separate fault. So no. Petrol remains in that tank later on, whatever else goes in, and the pump gets no reprieve from it.

Main dealers and petrol in a diesel

You do not need one. The car is drained and cleaned wherever it is, with no need to take it to a main dealer.

Is the vehicle still with you?

Shut off is how the car remains.

If you have already driven the vehicle, pull over somewhere safe, switch it off and leave it off. This is recoverable from a lot more regularly than motorists expect, and a still, cold vehicle is the best place to be in.

Throughout Staffordshire and around Wombourne: call-out fuel draining, at home or on the forecourt or at the kerbside.
