Petrol in a Diesel Car in Etherley Dene

Do not fire up the engine. While the fuel is still sitting in the tank and the motor has not yet run, a drain is nearly always all it takes — and that is decided in the next few minutes, not by how much was put in. Petrol in Diesel drains and flushes wrongly fuelled vehicles where they are, all over Etherley Dene and the remainder of Durham, on the forecourt, at the roadside or on a drive. Ring us and then our technicians will show you what follows from here before you try anything else.

Petrol in a diesel: what to try first

  • Never start it — and do not trust it when it fires up. Here is the part motorists get wrong about petrol in a diesel in particular. A petrol motor given diesel typically just will not run, so the person stops and the harm stops with them. A diesel filled with petrol normally starts, idles and drives off just fine for a few miles. It isn't fine. It's eating into the fuel system as you drive.
  • Two things, diesel: it combusts, and on the way through it keeps that high-pressure pump and injectors protected. Petrol only does the one. That is why your ignition remains off also — flick it on and you often prime that system, and that's petrol leaving your tank for precisely those parts.
  • Don't thin it. Diesel poured 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 accepts petrol. Super unleaded? Still petrol. The type makes no difference.
  • We'd much rather drive to an awkward spot than have it started — so if you sensibly can, stay still. Nothing is simpler to handle than a vehicle that has never shifted. On the verge on Snowdrop Way, that means hazards on and leave the vehicle.
  • Before you phone, gather your whereabouts. Anything nearest to you with a sign on it, plus a postcode beginning DL14 0 — that's what decides whether the technician shows up or circles.
  • Phone 0333 366 0103. Prepare for three points — what went in, about how many litres, plus if the car has been turned over. The replies decide all that follows.

Removing petrol from your diesel at the forecourt

A fair chunk of this work gets completed at the pump, because that is where it mostly begins. If you're still at the forecourt at JET, that is generally where the drain happens — we work on petrol station forecourts routinely, with the station's agreement.

At a forecourt, it gets spotted with the motor never run, and nowhere else does that. Our engineers can still sort it out where it is, even away from the forecourt. In a car park, on a private drive or in a lay-by, your car has been switched on and driven there, and that pulled fuel through the filter then into the high-pressure fuel pump, right from your tank. None of that is a catastrophe, although the flush then has to go past your tank to the lines and the fuel filter, and the few seconds between seeing the till receipt and going for your key are what decide that.

The attendants will usually help you roll the car clear of the petrol pump so the next driver can get by. It is worth doing. Shifting it four spaces doesn't warrant cranking it.

Mobile fuel drain van at a diesel car in Etherley Dene

Each start primes your fuel system and draws more of that mix out of that tank and toward the pump — which is why a car shuffled twice into a nicer bay has silently become a bigger job than one left just where it stopped. So where we cannot work alongside your diesel Skoda Octavia, our technicians shift it without starting it. None of that is fuss about a couple of seconds of running. Car parks like the one outside Morrisons our technicians attend regularly, and your fuel is rarely the difficult part: the bay is. Motors either side, a trolley shelter behind, at times a height barrier at the way in settling if our van reaches you at all. Tell us how boxed in you are, and which way the vehicle faces.

A passer-by will urge you to move the car out of the gateway and fix it later. Do not. A misfilled diesel Peugeot 308 on the zig-zags outside Escomb Primary School is an inconvenience; the same vehicle restarted three more times to be courteous is a fuel system rather than a tank. Every restart primes your lines and pulls more petrol past your filter then into your pump. Stay put, let people moan, then phone us.

Fine on the way out, flat on the way back. If that is how that drive to West Mills Playing Fields went, that tank is where to look. Petrol thins diesel, and runnier fuel seeps past the precision components that are meant to build injection pressure — so the further your Ford Focus went, the less well it held that pressure. Stop somewhere safe, switch off and ring us.

About as well as this goes, once your engine has turned: away from the pumps, receipt read, and your diesel Dacia Duster left near Escomb War Memorial barely two streets on. Phone us, then leave the vehicle off. A short distance does really help. It was still a start and still a drive, though, so your filter and the pump have had diluted fuel through them — hence cleaning the fuel lines rather than only draining your tank.

Hire car or company car? Call them before you ring us — some contracts want the hire firm to sign off the work, and sorting that out first is a great deal quicker than sorting it afterwards. Then phone us about the Mercedes E-Class near Bishop Auckland RUFC, and don't worry that you cannot say how full that tank was. Nearly nobody can, in a motor they collected two days ago, and we work it out on the spot. The reason we ask is that petrol in a diesel does its harm as a share: the same few litres in a nearly empty tank is a far stronger mix 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 the blend, the more it knocks, smokes and goes flat.

Places we cover near Etherley Dene

The same trips carry us to Etherley Moor, Woodhouses, High Escomb, Escomb and California as well as Etherley Dene, which is a residential suburb.

Not on the list? That says nothing. The places above are only the nearest few, and nearly all towns in Durham have a page of their own somewhere on our site. Contact us to check instead of assuming — boundaries especially, and anywhere your satnav might misread.

This map outlines the area the page covers. The car doesn't need to travel to us. We work throughout every bit of that — kerbside, forecourts, driveways, car parks.

Stranded on the roadside somewhere in Etherley Dene?

The opportunity to pull over anywhere safe does not fall to everybody. A common call for us instead of an odd one: worked out after setting off, finished up on the verge on Rochester Close or in a lay-by with the hazard lights on.

Whether you wait with the car or step clear of it turns on whether staying in it seems safe. Do not start it up to reach a better spot. It will go — a diesel on petrol usually obliges — and each mile of obliging drags the mix deeper into the fuel system. A van coming to an awkward spot is no problem for us, and it's much better for the car than driving on.

So you've driven it? Petrol in a diesel over a few miles

This is where the A1(M) comes in — under 10 miles away from Etherley Dene. Some way along, and onto it in the first place: a wrongly fuelled diesel will often do both before anything seems wrong. What you get then is seldom a tidy stop. Power ebbs away, the idle goes uneven, and there may be some smoke.

Come off at the next safe exit, switch off, and never start the vehicle to reposition. Presume the worst of it on a long trip. Anything close to the under 10 miles to the closest city, and the mixture has been through the fuel filter, through the pump, through the injectors. Say so when you phone. What we bring alters.

Where's Etherley Dene?

Etherley Dene is a suburban area situated on the riverside in County Durham, with a mix of detached housing and a population of around 2473 residents. Etherley Dene sits at an elevation of 117 metres, close to nearby places such as Etherley Moor and Woodhouses. Etherley Dene is located near the city of Durham, approximately 9.7 miles away, and is part of the wider North East region. Etherley Dene benefits from its scenic riverside setting, with the River Wear flowing through the area.

What follows when our engineers arrive with you in Etherley Dene

  • We ask first, quote after. What went in? How much? Has your motor run? Those replies alter what the work actually is.
  • We empty that tank of the contaminated fuel.
  • Lines cleaned, filter cleaned. Whatever is left after that isn't the thing that started the problem.
  • Fresh diesel goes in, and then the fuel system gets primed.
  • Your engine is started and tested to make sure it runs properly on new diesel.

The car is then ready for you to drive away. All of it is done where the vehicle is, so it never has to be taken to a garage, and when it has been caught early, lasting damage is very unusual.

AdBlue in your diesel tank by mistake, around Etherley Dene?

The issue is not the same, though the first rule is — do not crank it — if what went in was AdBlue rather than petrol. The lubrication a fuel system depends on is taken away by petrol, which thins your diesel. Urea in water, AdBlue, and in a diesel tank that causes corrosion and residue.

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

Paying for a petrol-in-diesel fuel drain around Etherley Dene

What changes the price is laid out below, as the job isn't one job and our engineers cannot frankly put a single number on this page.

  • This is the key one: whether your motor has been run, or driven.
  • Wrong fuel in, against what your tank holds — that proportion.
  • The sort of liquid in the tank, unleaded or AdBlue.
  • Where your vehicle is, and whether our van can safely get to and work on it.

A firm answer instead of a range is what you get for telling us three things: the car, the amount, and whether it has run. For your car at home that's going nowhere and is not pressing, is fine too.

Petrol in diesel questions from Etherley Dene drivers

At a petrol station around Etherley Dene, can you do a fuel drain there?

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

How much petrol is too much for a diesel?

It rests on the ratio instead of the litres, and a lot more on whether your engine has run. Five litres in a nearly empty tank is a separate situation from five in a full one — but either way, the thing that determines how much work is required is whether that blend has been pulled through your fuel system.

Already driven it with petrol in your diesel? Now what?

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

Fuel drains and manufacturer warranties

A drain and flush carried out properly is not an alteration and doesn't invalidate a manufacturer's warranty. Another good reason to leave it switched off: running a diesel on petrol is the thing more likely to cause an argument with one.

Can I just add two-stroke oil and drive home?

What petrol has diluted is not put back by two-stroke oil, which is an old fix for a distinct issue. So no. Petrol remains in that tank later on, whatever else goes in, and your pump gets no break from it.

Main dealers and petrol in a diesel

Not at all. We drain and clean the car wherever it is, so there's no need to bring it to a franchised dealer.

Still with your car?

Do not turn it on again.

Switch it off somewhere safe and leave it off, if you have already driven it. A parked, cold car is the best position to be in, and this is recoverable from much more frequently than drivers fear.
