Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Cross Hill?

With the tank still carrying the fuel and the engine not yet run, nearly every job requires only a drain, so leave your engine off. That result is settled in the minutes immediately after filling up, rather than by the amount that was put in. Across Cross Hill and the remainder of West Yorkshire, Petrol in Diesel drains your car and flushes it where it stands, whether at a roadside, on a drive or at a forecourt. Call us before all else starts, so you will know what happens next.

The next five minutes: petrol in a diesel

  • Give a petrol motor diesel and it will normally refuse to run at all, so the driver stops there and so does the damage. Feed a diesel petrol and the engine starts, it ticks over, it drives off — fine enough for several miles. Drivers have that backwards, which is the bit they get wrong about petrol in a diesel specifically. So never start the car. And once started, never rely on it: your fuel system is wearing while you drive.
  • Diesel ignites, and before it ignites it greases — the injection pump, those injectors. Petrol manages only the burning. So leave your ignition alone as well: flicking it on is frequently sufficient to prime your system, and priming draws petrol from the tank into precisely those parts.
  • Do not tip diesel on top to water down it. A diesel fuel system does not cope with petrol by percentage the way that advice suggests, and topping up removes nothing — it simply hands you a bigger tank of the same mix. The grade makes no difference either: super unleaded is still petrol.
  • Wait where you are if you safely can. A vehicle that has never shifted is the quickest one to deal with, and we would rather travel to a tricky location than have it started. If you are stopped on the verge on Barnsley Road, switch the hazards on then leave it there.
  • The van turning up rather than circling hinges on two things: a postcode starting WF9 4, and whatever is nearest to you with a name on it. Have both ready before you dial.
  • Phone 0333 366 0103. Let us know what was put in, about how much, and if the car has run. These three answers determine the whole job.

The journey back would about double it, for no reason at all. One commute has already pushed a real load of petrol-thinned diesel through your high-pressure pump of that Volkswagen Passat. So keep it where it is. Call us from the platform if that is easier — no one needs you hovering over your car outside Fitzwilliam while our engineers work, and tonight beats finding out on Monday.

If you've put petrol in your diesel Nissan Qashqai around Cross Hill and you are now stuck at Tesco with a boot loaded with shopping, phone us. Don't start it a second time to get out of that bay. We will get to you, drain your tank, rinse your fuel lines and put fresh diesel in so you can head home. A mile or so at gentle throttle pulls little of it, so these are often the easy ones.

Nothing tells you, as from behind the wheel there's nothing to be warned about. Your diesel Ford Focus will have seemed entirely normal on the way back from Sacred Heart Catholic Primary School, and they all do — which is the trap with petrol in a diesel and not the reverse. Diesel in a petrol motor generally refuses to run, stopping the motorist and stopping the damage with them. Petrol in a diesel fires up, idles, pulls away as though nothing had happened, and all the while your pump works without the lubrication its fuel is supposed to supply. Tell us approximately how far, and how hard. The harder counts more.

None of it is your engine failing. That's the part worth hearing, and it's why the ordinary Butcher Wood call ends better than it sounds: a diesel Audi A3 drives out there without a murmur, comes back with the power gone, the idle lumpy and possibly a little smoke, and the cause is the fuel no longer behaving like diesel. Diesel has to be thick enough to seal the close-fitting components it flows through; petrol thins it; and a diesel injection system is hydraulic as much as chemical, needing the fuel to hold pressure instead of only to burn. So pressure that should build then stay built leaks past tolerances, delivery shows up weaker and later and less even than built, and all of that stops once the fuel is sorted.

About as well as this goes, once the motor has turned: away from the pumps, receipt read, and your diesel BMW 5 Series left by Hemsworth Library hardly two streets on. Phone us, then leave the car off. A short drive does really help. It was still a start and still a drive, though, so your filter and the pump have had weakened fuel through them — hence purging the fuel lines rather than only clearing that tank.

Forecourt drains for petrol in a diesel

Most of this work starts at a forecourt, which means a good part of it ends up completed there. If you are still on the forecourt at Tesco, that is typically where the drain takes place — our technicians work on petrol station forecourts all the time, with the owner's consent.

A filling station is the one place the mistake is stopped before the engine has run. Everywhere else — a car park, a private drive, a lay-by — the vehicle was switched on and driven to get there, which means fuel was drawn from that tank, through the filter and into the high-pressure fuel pump. That is not a calamity, and our technicians can still deal with it where it stands. It does mean the fuel lines and the fuel filter need rinsing as well as the tank, and that is determined by the few seconds between reading the receipt and going for your key.

Roll the car out of the way if the attendants suggest it, and they usually will. The next motorist gets through the pump, and that is worth doing. Four car lengths isn't worth the risk.

Cross Hill plus the places near it

These same trips carry us to Hemsworth, Green Hill, Highfield, Little Hemsworth and Common End as well as Cross Hill, which is a residential suburb.

Not on the list? It says nothing. The names above are just the nearest few, and the majority of locations across West Yorkshire have a page of their own somewhere on this site. Phone and check rather than assuming — boundaries above all, and anywhere your phone may misread.

This map outlines the ground this page spans. Kerbside, forecourt, private drive, car park: the lot is territory our engineers serve, and none of it requires the car to move to us.

Stuck on the kerbside in Cross Hill

Not everybody gets a decent place to pull in. A normal call for us and not a rare one: realised after setting off, landed by the verge on Cross Hill or in a lay-by with your hazards on.

Clear of the vehicle if it's not wise to wait there, beside it if it is. Every mile a diesel obliges you for on petrol draws that blend further into the fuel system — and oblige it frequently will, which is why the engine doesn't get restarted to limp somewhere handier. A van coming to an awkward spot is no trouble for us, and it is a lot better for your car than carrying on.

Run it already? Stop, then read below

under 10 miles out of Cross Hill, your A1(M) is what counts now. A wrongly fuelled diesel will usually take you onto it and some distance along before anything feels wrong, while the symptoms when they come are usually lost power, a lumpy idle and some smoke instead of a tidy stop.

Pull off at the next sensible exit, switch off, and do not restart the car to move it. Long drive? Anything close to the under 10 miles to the closest city and you should presume the lot — filter, pump, injectors, all of that got to by the mixture. Say that on the call, because it affects what goes in our van.

All about Cross Hill

Cross Hill is a suburban area situated on the riverside in West Yorkshire, with an elevation of around 65 metres. Cross Hill lies approximately 7.6 miles from Wakefield and is near other local places such as Hemsworth and Green Hill. Cross Hill has a population of around 5765 people and predominantly consists of semi-detached housing. Cross Hill is located within a wider region that is about 154.4 miles from London.

What our technicians do when our engineers get to you in Cross Hill

  • Our technicians ask first, quote after. What got in? How much? Has your motor run? Those answers alter what the work actually is.
  • The contaminated fuel comes from that tank.
  • Lines flushed, filter cleared. Whatever remains later is not the thing that caused the issue.
  • Clean diesel goes in, and then your system gets primed.
  • It's started with fresh diesel in it, and we check that it's running properly.

The vehicle is then ready for you to drive away. Everything is done where the car is, so it never needs to be taken to a workshop, and when it has been noticed quickly, lasting damage is very rare.

Cross Hill AdBlue removal is a separate problem

AdBlue instead of petrol? Then the first step is unchanged — your engine stays off — whereas this fault underneath it's a different one altogether. The protection a fuel system depends on is stripped away by petrol, which weakens the diesel. AdBlue is urea dissolved in water, and in a diesel tank it brings rust and build-up in its place.

Both are ours. There is a separate Cross Hill page for AdBlue removal, with the detail on it — including the reasons it often turns out to be the worse of the two.

Paying for a petrol-in-diesel fuel drain in Cross Hill

Our engineers can't put one price on this page honestly, because the job is not one job. What moves it:

  • Started? Driven? Either answer counts more than anything else on this list.
  • The tank's capacity, set against how much of the wrong fuel got into it.
  • Which went in: petrol or AdBlue.
  • Where is it? And can our van reach it and work there safely?

Tell us your car, the amount and whether it has run, and you'll get a straight answer instead of a range. Vehicle at home, going nowhere, nothing time-critical about it — is good for that.

Things we hear about petrol in diesel in Cross Hill

I am on a forecourt in Cross Hill. Can you drain the car here?

A good share of this work takes place there, so yes. Tell us which one you are at when you ring and we'll tell you whether we can work there. With the owner's agreement our engineers visit Esso and the other forecourts locally regularly.

How much petrol in a diesel is too much?

It depends on the ratio rather than the litres, and a lot more on whether the motor has run. A nearly empty tank with five litres in it, against a full one with the same five: distinct situations, definitely. Either way, the work required comes down to one thing, which is if the system has had that mix drawn through it.

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

Stop sensibly. Off. Nothing after that. Driving is what takes the issue from that tank into the pump and injectors — but it is recoverable a lot more often than drivers expect, and the single most useful thing you can do now isn't restart it.

Will a fuel drain void my warranty?

It is not an alteration, so a drain and flush carried out correctly does not void a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a disagreement with one.

Adding two-stroke oil, then driving home

Two-stroke oil solves a different fault, and an old one at that. Nothing it does puts back what petrol diluted. No. Your tank still has petrol in it afterwards, and the pump still has to cope with it.

Does petrol in a diesel have to go to a main dealer?

Not at all. We drain and flush the car wherever it is, so there is no need to take it to a main dealer.

You, and your car, still together?

Switched off is how it remains.

Driven it already? Then somewhere sensible, stop, turn off, and no restarting it afterwards. This is recoverable from a lot more regularly than people expect, and a still, cold car is the best position to be in.
