Clifton: Put Petrol in a Diesel Car?

Don't fire up your engine. If the fuel is still in the tank and the engine has not run, a drain is nearly always all it needs — and that is determined in the following few minutes, not by how much went in. Petrol in Diesel drains and flushes wrong-fuelled vehicles where they are, throughout Clifton and the rest of Nottinghamshire, on the forecourt, at the roadside or on a private drive. Just one ring our way is plenty: our engineers can show you what happens next. Make that right away.

Now what? Petrol in a diesel, step by step

  • Give a petrol motor diesel and it will usually fail to run at all, so the driver stops there and so does the harm. Feed a diesel petrol and the engine starts, it idles, it moves off — fine for a few miles. Most people have that reversed, which is the part they get wrong about petrol in a diesel especially. So never fire it up. And once started, never rely on it: that fuel system is wearing down whenever you drive.
  • Diesel ignites, and before it combusts it lubricates — that high-pressure pump, those injectors. Petrol manages only the burning. So leave the car's ignition be as well: flicking it on is commonly enough to prime your system, and priming moves petrol from the tank into exactly those components.
  • Topping up removes nothing. It gives you a bigger tank of the same mixture, since a diesel fuel system will not cope with petrol by percentage as that advice assumes — so don't pour diesel on top to water down it. Grade is beside the point too: super unleaded is petrol.
  • Sit tight if it is sensible to. Hazards on, ignition off, keep it. Wherever you have stopped — the verge on Southchurch Drive, anywhere — a difficult location for us is better than a started motor, and nothing is quicker for us to sort than a vehicle that never moved.
  • Find out where you are before ringing. A postcode that starts NG11 9, and the name of whatever is nearest to you. Otherwise the van circles rather than turning up.
  • Call 0333 366 0103. Say what was put in, approximately how many litres, and also whether the car has started. These three replies settle your whole job.

The drive back would roughly double it, for no purpose at all. One commute has already forced a real amount of petrol-thinned diesel through the high-pressure pump of your Volkswagen Passat. So leave the vehicle where it stands. Call us from the platform if that's easier — nobody needs you hovering over your car outside Beeston whilst our technicians get on, and tonight is better than finding out on Monday.

The enquiry we hope for goes like this: diesel Renault Clio, some litres of unleaded, run a couple of miles, now shut off outside Heron Foods. What we are really asking is how much fuel the pump has pulled — not how long ago it was.

None of that is the engine failing. That is the bit worth hearing, and it is why the ordinary The Kieron Hill Clifton War Memorial Garden call ends better than it sounds: a diesel Ford Focus drives out there without complaint, comes back with the power gone, the idle lumpy and maybe a little smoke, and the cause is the fuel no longer behaving like diesel. Diesel has to be thick enough to seal the precision parts it runs through; petrol dilutes it; and a diesel injection system is hydraulic as much as chemical, needing your fuel to hold pressure rather than only to burn. So pressure that should build then stay built leaks past tolerances, delivery shows up weaker and later and less even than designed, and all of that stops once your fuel is put right.

About as well as this goes, once the motor has turned: away from the pumps, receipt read, and your diesel Mercedes C-Class left near Clifton Library barely two streets on. Call us, then leave the car off. A short drive does truly help. It was still a start and still a drive, though, and so the filter and your pump have had thinned fuel through them — hence flushing the lines rather than only emptying that tank.

Authorisation first, where there's a hire firm or a company behind your car — some contracts insist on it, and settling that beforehand saves a great deal of time later. After that, call us about your diesel Dacia Duster near Clifton Young People's Centre. You'll not know how full your tank was. Hardly anybody does, two days into a car, and it gets worked out there anyway. Our engineers ask because the harm petrol does in a diesel is proportional: a couple of litres in a nearly empty tank make a much stronger blend than the same few in a full one, and since petrol is engineered to resist igniting under pressure, which is exactly what a diesel relies on, the stronger it gets the more the motor knocks and smokes and flattens off.

Mobile fuel drain van at a diesel car in Clifton

Pump-side draining for petrol in a diesel

The work begins at a forecourt, generally. Regularly the job wraps up on site as well. We work on garage forecourts all the time, with the station's agreement, and so if you are still at Esso that's typically where the drain gets done.

At a garage, the mistake is spotted with the engine never run, and no place else manages that. Fuel sucked out of that tank and through the filter, all the way to your high-pressure pump, is what happens when the motor is started and the car is moved to where it is now: the car park, the driveway or the lay-by, everywhere other than the forecourt. So the flush includes your filter and the fuel lines as well as that tank. That is still not a catastrophe, and our engineers put it right where your car sits. What decides it is whether the key was reached for in the seconds after the receipt was read.

Staff will generally pitch in pushing it away from the pump, which lets the next customer get past. Take the help. Four car lengths isn't worth a restart.

Areas our vans serve near Clifton

Ruddington, Rylands, Wilford, Barton in Fabis, Attenborough — each of those on the rounds that bring us over to Clifton too, a small village.

There are pages for most places around Nottinghamshire, and the ones named above are merely the immediate neighbours — so yours being left off the list says nothing whatsoever about if we come. Contact us to enquire rather than guessing — county lines particularly, and anywhere your satnav tends to misread.

That map shows the area this page includes. The car does not need to move to us. Our technicians work over all of it — roadside, forecourts, driveways, car parks.

Clifton: broken down wherever you stopped

The chance to pull in anywhere sensible doesn't fall to everybody. Hazards flashing at a lay-by somewhere, or pulled onto the verge beside Green Lane as you realised after setting off — our engineers take that call so often that it's the normal kind.

Remain with the motor if it is wise to wait inside, yet out of the vehicle when it is not. It will frequently oblige. A diesel running on petrol limps along very willingly, and that's the trouble: restart the vehicle to get to somewhere handier and the mixture goes further into your fuel system with every mile travelled. Our van heading to a difficult spot is no trouble for us, and it is far better for the vehicle than carrying on.

Driven it already? Stop, and read below

Your M1 is the one that counts here, and it runs under 10 miles from Clifton. It will frequently get you onto it, and some way along, before you spot a thing. Then it's some smoke, an uneven idle and power falling away — not a tidy stop. Misfilled diesels rarely give you one of those.

Take the first junction that is sensible, pull up there, and don't start the vehicle to move it. Presume the worst of it on a long run. Anything close to the under 5 miles to the nearest city, and the mixture has been through the fuel filter, through your pump, through the injectors. Tell us when you ring. What our technicians bring differs.

About Clifton

Clifton is a locality in Nottinghamshire, situated on the banks of the River Trent at an elevation of 44 metres. Clifton lies close to the city of Nottingham, approximately 3.9 miles southwest of the city centre. Clifton is characterized by its predominantly terraced housing stock and forms part of the wider Nottingham urban area, with nearby places including Ruddington, Rylands, and Wilford.

When we reach you around Clifton: what we do

  • Three things get asked before any price — your fuel that went in, the amount, and whether anything has been run since. Each answer shapes the work.
  • Our technicians drain the tank of all the polluted fuel.
  • Our technicians flush the lines and clean the fuel filter, so what's remaining in the fuel system is not what caused the issue.
  • Our engineers put clean diesel in and bleed your system.
  • The engine is fired up and tested to be sure it runs correctly on clean diesel.

Then it is ready to pull away. All of this is done where your car is, so it never has to be taken to a workshop, and when it has been caught soon, lasting damage is very unusual.

AdBlue in a diesel tank around Clifton is a different problem

Never fire it up: that opening step holds whether what was put in was AdBlue or petrol. What differs is the fault itself. Petrol thins the diesel and removes the lubrication the fuel system depends on. AdBlue is urea in water, and in a diesel tank it brings rust and build-up in its place.

AdBlue removal in Clifton has a page of its own with the detail on it, including why it is often the more serious of the two. Our engineers cover both.

Budgeting for a petrol-in-diesel fuel drain in Clifton

One figure would not be fair here, because this isn't one job. These are the things that move it:

  • Has it been run or driven? Nothing else matters for as much.
  • How much of the wrong fuel went in, judged against how much your tank holds.
  • Whether it was unleaded or AdBlue.
  • Where the vehicle is, and whether a van can safely reach and work on it.

Tell us what your vehicle is, how much got in, and if the engine has run. A clear answer comes back, not a range. For your car at home that is going nowhere and is not time-critical, works too.

Clifton drivers ask us these about petrol in diesel

Fuel drains on a Clifton petrol station forecourt

A large part of this work gets done there, so yes. Our engineers work at BP and the other forecourts around town routinely, with the site's agreement — tell us which one you are at when you call and we'll tell you if our technicians can work there.

How much petrol is too much for a diesel?

Proportion settles it rather than litres — and more than either, whether the motor has run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same query in the end: has that mix been sucked right through, or has it not?

I drove it after putting petrol in my diesel. What next?

Turn off somewhere safe, and keep it that way after you stop. Driving is what takes the issue from your tank into the pump and injectors — but it's salvageable a lot more regularly than drivers fear, and the single most valuable thing you can do now is not restart the car.

Is a fuel drain going to void my warranty?

No. Carried out correctly, draining and cleaning is no modification at all, and the warranty from your manufacturer is untouched by it. Another good reason to leave it switched off: running a diesel on petrol is the thing likelier to cause a disagreement with one.

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

Two-stroke oil solves a distinct problem, and an old one at that. Nothing it does puts back what petrol thinned. No. That tank still has petrol in it afterwards, and your pump still has to put up with it.

A main dealer for petrol in a diesel — needed?

There is no need to bring it to a franchised dealer, because we drain and clean the vehicle wherever it is.

You, and your car, still together?

Shut off is the way the car remains.

Driven it already? Then somewhere sensible, stop, turn off, and no restarting it after that. A still, cold vehicle is the best place to be in, and this is recoverable from a lot more regularly than motorists assume.

Across Nottinghamshire and in Clifton: on-site fuel draining, at home or on the forecourt or at the roadside.
