Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Harwood Bar?

With the tank still carrying the fuel and the motor not yet turned over, nearly every job requires only a drain, so leave the engine off. That result is determined in the minutes straight after filling up, and not by the amount that was put in. Across Harwood Bar and the rest of Lancashire, Petrol in Diesel drains your car and cleans it where it stands, whether at a roadside, on a drive or at a forecourt. One call our way will be plenty: our technicians can explain what follows after this. Do this first.

What next? Petrol in a diesel, step by step

  • Don't crank it — and never rely on it when it does start. This is the thing motorists get wrong about petrol in a diesel specifically. A petrol engine fed diesel normally just cannot run, and so the driver stops and the harm stops with them. A diesel filled with petrol normally starts, idles and drives away without complaint for a few miles. It's not all right. It's grinding your fuel system while you drive.
  • Flicking the ignition on usually primes that system, and priming is what moves petrol out of that tank and into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it combusts. Petrol manages the burning and none of the oiling. Leave the ignition off.
  • Never dilute it. Diesel added on top takes out nothing, so all you have is more of what was already there, because percentage isn't how a diesel fuel system handles petrol. Super unleaded? Just petrol. The grade makes no difference.
  • A car that hasn't moved is the quickest one to deal with, so wait where you are if you sensibly can. Parked on the verge on Whalley Road? Hazards on, then leave the car there. A tricky spot works for us better than a started engine.
  • Before you ring, gather your position. Anything next to you with a name on it, plus a postcode beginning BB6 7 — that is what determines whether the van turns up or circles.
  • Call 0333 366 0103. Tell us what got in, about how much, and if your car has started. Those three facts decide the full visit.

On the forecourt: removing petrol from the diesel

Forecourts are where this job mostly kicks off, and where a large part of it closes. If you are still at the forecourt at Texaco, that's normally where this drain takes place — our technicians work on garage forecourts regularly, with the station's permission.

Before your motor has fired — a garage is the single setting this is stopped. Fuel pulled out of the tank and through the filter, all the way to the high-pressure pump, is what happens when the motor is switched on and the car is driven to where it is now: the car park, the private drive or the lay-by, anywhere other than the forecourt. So the flush takes in your filter and your lines as well as your tank. That is still not a catastrophe, and we deal with it where the car sits. What decides it is whether the key was reached for in the seconds after the till receipt was checked.

The attendants will normally offer to push it out from the petrol pump so the next driver can get past. It is worth doing. Starting the car just to move four car lengths is not.

Mobile fuel drain van at a diesel car in Harwood Bar

If you've put petrol in the diesel Mercedes C-Class in Harwood Bar and you're now stranded at Aldi with a boot packed with shopping, phone. Never fire it up a second time to leave that spot. We'll head your way, empty your tank, flush your fuel lines then put clean diesel in so you can drive home. A mile or so at gentle throttle pulls little diesel, so such jobs are usually the straightforward ones.

You'll be urged to move the car out of the gateway and sort it out later. Please don't. On the zig-zags at St Hubert's Roman Catholic Primary School, Great Harwood, a wrongly fuelled BMW 1 Series running on diesel is in the way, and that is all it is. Fire it up three more times being polite and you have turned a tank into a fuel system: every start primes your lines, every prime drags more petrol through the fuel filter on to your pump. Let them complain. Call us.

Three replies decide much of the work: what got in, approximately how much, and whether the motor has run since. We ask for them when we arrive at the vehicle in the car park outside Park Hotel. Next the polluted blend comes out of that tank, the fuel lines are flushed, and where your Peugeot 208 has a serviceable filter, it comes off. Once fresh diesel is in and the system bled, we fire it up and make sure it runs smoothly before you set off.

Petrol in a diesel does its damage as a ratio, which is the reason our technicians ask at all: the same few litres sitting in an almost empty tank make a far stronger blend than they would in a full one. And petrol is rated on how well it withstands igniting under pressure — the opposite of what a diesel needs — so a stronger mixture rattles more, smokes more, goes flatter. None of which means you need an answer ready. Almost no one knows how full your tank was in a car collected two days ago, and our technicians work that out on the spot. Do call the hire or company firm first, though: some agreements want them to sign off the work, and that's far faster settled before than after. Then ring us about the Volvo XC60 close to Saint Bartholomews (Old Church).

Purged, not emptied — that's what a diesel Skoda Superb which got as far as Town_Hall needs. Running a diesel puts the mixture into the fuel filter, the lines, your pump and its rail, none of which empties with that tank, and so by now that tank holds the smaller part of the damage.

Harwood Bar and the areas next to it

The same rounds take us to Hyndburn Bridge, Hindle Fold, Lower Fold, Cliffe and Great Harwood as well as Harwood Bar, which is a residential suburb.

There are pages for nearly all locations around Lancashire, and the ones mentioned above are merely the closest neighbours — so yours being absent from the list tells you nothing about if our engineers come. Close to a boundary, or anywhere a satnav can't find? Contact us and check instead of presuming.

See our map for the area covered here. The car doesn't need to move to us. Our technicians work throughout the lot — roadside, forecourts, driveways, car parks.

Broken down by the kerbside in Harwood Bar

The opportunity to pull over anywhere sensible doesn't come to everyone. If you worked it out after setting off and landed on the verge of Harwood Lane, or at a lay-by somewhere with the hazards flashing, that is a routine call for us rather than a rare one.

Whether you sit beside the motor or stand away from it rests on whether sitting nearby looks safe. Every mile a diesel obliges you for on petrol pulls the blend further into the fuel system — and oblige it often will, which is why the engine does not get restarted to limp somewhere handier. However awkward the spot, it's no trouble for us to get to it, and that's much better for your car than driving on.

Driven it already? Stop, then read below

Your M65 is the road which counts now, and lies under 3 miles from Harwood Bar. It will often take you onto it, and some way along, before you feel a thing. Then it is some smoke, a rough idle and power falling away — not a tidy stop. Wrongly fuelled diesels seldom give you one of those.

Do not start it to move it. Get off at the first safe exit and switch off. On a longer run — anything close to the under 15 miles to the nearest city — take it the mixture has been through the filter, the pump and the injectors, and mention it when you call. It affects what our engineers bring.

Harwood Bar itself

Harwood Bar is a suburban area situated on the riverside in Lancashire, with a mix of semi-detached housing and a relatively low elevation of around 100 metres. Harwood Bar is located near several other local places, including Hyndburn Bridge, Hindle Fold, and Lower Fold, and is approximately 12.9 miles from the city of Preston. Harwood Bar has a population of around 1968 residents, who are likely to commute to nearby cities for work or services. Harwood Bar is also relatively distant from London, at around 184.1 miles away.

The job in Harwood Bar, step by step

  • We check what went in, how much, and whether the engine has run. The replies alter the work, which is why our technicians ask before quoting.
  • We empty that tank of all the contaminated mixture.
  • What is remaining in the system should not be what created the trouble, so your fuel lines get purged and your filter cleared.
  • Priming follows, once new diesel is in.
  • Once it is started, we check it runs correctly on clean diesel.

Then it's ready to set off. Long-term damage is very rare when it has been noticed early, and because all of this is done where your car is, it never needs to go to a workshop.

AdBlue in a diesel tank in Harwood Bar is a different job

The fault isn't the same, though the opening rule is — never start it — if what went in was AdBlue instead of petrol. The lubrication a fuel system relies on is taken away by petrol, which weakens the diesel. AdBlue is urea dissolved in water, and in a diesel tank it causes rust and residue instead.

AdBlue removal around Harwood Bar has a page of its own with the detail on it, including why it is usually the more serious of the two. Our engineers cover both.

What a petrol-in-diesel fuel drain costs around Harwood Bar

What changes the price is set out below, because this job isn't one job and we can't honestly put a single number on this page.

  • Whether your motor has been started or driven. This is the key one.
  • How much of the wrong fuel got in, set against how much the tank can hold.
  • AdBlue or unleaded, whichever went in.
  • Where is it? And can our van reach it and work there sensibly?

A firm answer rather than a range is what you get for telling us three things: the car, the quantity, and if it has run. If it's not time-critical — the vehicle is at home and going nowhere — is fine too.

Petrol in diesel queries from Harwood Bar drivers

Fuel drains on a Harwood Bar petrol station forecourt

A big share of this work takes place there, so yes. Often, provided the site consents: Ridings Auto Services, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our technicians can work in that location is something we answer straight away.

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

It hinges on the ratio rather than the litres, and far more on whether your engine has run. What determines how much work is needed is if that mix has been pulled through the fuel system — because though five litres in a nearly empty tank is a separate case from five in a full one, either way that's the query.

I put petrol in my diesel and drove the car. What now?

Stop somewhere safe, switch off, then keep the vehicle off. Driving shifts the issue along — out of that tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really valuable thing left to you is not restarting the vehicle.

My warranty — does a fuel drain void it?

No. Carried out properly, clearing and rinsing is no modification at all, and the warranty from your manufacturer is unaffected by it. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.

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

No. It belongs to a separate issue from a bygone era, and petrol has weakened something no oil of that kind puts back. Petrol remains in that tank later, whatever else goes in, and the pump gets no reprieve from it.

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

Wherever the car is, our engineers drain and clean it there, so a trip to the main dealer doesn't come into it.

Waiting next to it?

The engine remains off.

Driven it already? Then somewhere safe, stop, turn off, and no restarting the vehicle afterwards. Cold, stationary, going nowhere: that is the best position to be in. Drivers fear this far more than they need to.
