Petrol in Diesel

Burnhead: Put Petrol in a Diesel Car?

If you have not started your engine as yet, do not. A fuel drain and nothing else is nearly always what a car requires while the petrol is still in that tank and your engine has not yet run, which is why it's the following few minutes that matter, not how much went in. Petrol in Diesel comes to your car wherever it has stopped in Burnhead or the remainder of Aberdeenshire, on the forecourt, by the roadside or on a drive, and drains and cleans it there. Call us so our technicians can tell you what comes after that before you do anything else.

What next? Petrol in a diesel, step by step

  • As you drive, the pump and your injectors wear. That's why you never fire it up, and why you do not depend on it once it has started. The trick about petrol in a diesel specifically — the point drivers get wrong — is that it drives away happily for the first mile or two. Diesel in a petrol engine generally will not run at all, which stops the driver and stops the harm with them. This one lets you carry on.
  • Diesel burns, and before it ignites it lubricates — the high-pressure pump, those injectors. Petrol handles only the burning. So leave the ignition be too: flicking it on is commonly all it takes to prime your system, and priming draws petrol from the tank into exactly those parts.
  • Do not pour diesel on top to thin it. A diesel fuel system won't cope with petrol by percentage as that guidance presumes, and topping up clears nothing — it just hands you a fuller tank of the same mix. The type makes no difference either: super unleaded is just petrol.
  • A vehicle that has not shifted is the quickest one to sort out, so remain where you are if you reasonably can. Parked on the verge on Archer Park? Hazards on, and leave the vehicle there. An odd location suits us better than a started motor.
  • A van turning up instead of circling depends on two things: a postcode starting DD10 0, and whatever is closest to you with a sign on it. Keep both prepared before you dial.
  • Three details determine the whole job: the stuff you poured in, the rough volume of it, and if anything has been turning since. The line is 0333 366 0103.

The journey in is what pushed weakened diesel through the pump. Standing still has pulled nothing. Petrol in a diesel Renault Clio, sitting outside Laurencekirk all day, sits dormant in the tank while it waits. Phone us first — before the keys go in.

Twenty to nine. Outside the local primary school. Late already, and your receipt in your hand reads unleaded. Switch the hazard lights on, leave the engine alone, and ring us. You could think three miles is nothing, in your BMW 3 Series or anything else — except that fuel is supplied to demand, and a dash taken in a hurry needs a great deal of it.

Out there happy, back flat. If that was the trip to St Cyrus National Nature Reserve, look at that tank. Diesel gets weakened by petrol, and thin fuel seeps past the close gaps supposed to build injection pressure — so every additional mile your diesel Mercedes C-Class covered, the less pressure it held onto. Somewhere safe, turn off, phone us.

Your pump rests ahead of your injectors, and so whatever a worn one sheds travels downstream with the fuel — which is why we are direct about not driving on. Call us, and leave your diesel Vauxhall Astra where it is close to St Cyrus Public Hall.

What takes place next is the issue. The engine immediately pulls the petrol still resting in the filter and the feed lines back round through the pump a second time, because draining a tank does nothing about fuel that has already left it. Drain it and put fresh diesel in, somebody confident will tell you — and that tip is only half right, as do it to a diesel Volkswagen Touran parked up, St Cyrus Parish Church say, and the thing starts, which is what makes it sound sensible. Phone us instead. Our engineers flush the circuit and take the fuel filter off where your vehicle has a serviceable one, and that is the difference between the vehicle being repaired and your car merely starting.

Mobile fuel drain van at a diesel car in Burnhead

Pump-side drains for petrol in a diesel

A good share of the work is finished at a pump, as that is where it often starts. The drain typically happens there and then. Still on the forecourt at Asda? Given the station's agreement, that's a spot we work, and regularly.

Before your engine has fired — a garage is the one place it is halted. The few seconds between checking your receipt and going for the keys settle how much requires cleaning. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the vehicle was started and moved to get there, so fuel was sucked from your tank, through the filter then into your high-pressure pump. That means the fuel lines and your filter need flushing as well as that tank. It is not a disaster, and our engineers can still sort it out where the vehicle stands.

Move the vehicle out of the way if the staff offer, and they normally will. The next customer gets past the pump, and that's worth doing. Four car lengths isn't worth a restart.

Will our engineers reach your end of Burnhead?

Being a residential suburb, Burnhead has a regular visit, and the areas nearby go along on that same run: Roadside and Lochside, St Cyrus and Kirkton, Bush.

Not on this list? It says nothing. The names above are simply the nearest few, and most places across Aberdeenshire have a page of their own somewhere on this site. Contact us to check rather than presuming, above all when you're on the border or anywhere your satnav struggles with.

The area the page includes sits on this map. The lot is territory our technicians serve: a kerbside, a forecourt, a driveway, a car park. You do not move the car anywhere.

Burnhead: stuck wherever you pulled up

Some people have no safe place to stop at all. Set off, then realised? Ended up along the verge beside Highview Grove, or parked in some lay-by with the hazards going? That is a routine call here. Not an unusual one.

Sit with the vehicle if it's sensible to be inside, yet clear of the car when it is not. Don't start it up to get to a better spot. It'll go — a diesel on petrol normally obliges — and each mile of obliging pulls that blend deeper into the system. Our van heading to a difficult spot is no bother for us, and it is far better for the car than carrying on.

Petrol in a diesel, but the car has gone

This is where the M90 counts, under 50 miles out of Burnhead. A wrongly fuelled diesel will frequently get you onto it and some way along before anything seems wrong, and the signs when they arrive are normally lost power, a rough idle and smoke rather than a tidy stop.

Never start it to move it. Pull off at the next safe exit and turn off. On a longer run — anything close to the under 50 miles to the closest city — take it the mixture has been through the filter, your pump and the injectors, and mention it when you call. It changes what we bring.

Burnhead itself

Burnhead is a small suburban area in Aberdeenshire, situated near the coast at an elevation of 82 metres. Burnhead lies within commuting distance of Aberdeen, which is 28.7 miles away, and is close to other nearby places such as Roadside, Lochside, and St Cyrus. Burnhead has a population of around 1028 people and predominantly features detached housing.

What follows when our technicians get to you around Burnhead

  • Three things get established before any price — the fuel that got in, the quantity, and whether anything has been run since. Each answer alters the work.
  • Our technicians drain that tank of the contaminated fuel.
  • Our engineers rinse the lines and clean the filter, and so what is left in your system is not what created the issue.
  • Fresh diesel goes in, and then the fuel system gets bled.
  • After it is turned on, we make sure it runs correctly on clean diesel.

That has your car ready to drive away. Long-term damage is very unusual when it has been spotted early, and as all of this is done where the vehicle is, it never has to go to a workshop.

AdBlue in your diesel tank instead, in Burnhead?

Do not start it: that opening rule stands whether what went in was AdBlue or petrol. What changes is this issue itself. The lubrication a fuel system relies on is stripped away by petrol, which dilutes your diesel. AdBlue is urea in water, and in a diesel tank it brings rust and residue instead.

Both are ours. There's a separate Burnhead page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two.

Burnhead pricing for a petrol-in-diesel fuel drain

Frankly, no single figure fits on a page like this. This job differs. Here's what varies it:

  • This is the big one: whether the motor has been run, or driven.
  • How much of the wrong fuel was put in, compared with how much that tank holds.
  • Which went in: petrol or AdBlue.
  • Where the vehicle is, and whether our van can safely reach and work on it.

Tell us what your vehicle is, how much went in, and if your motor has run. A firm answer comes back, not a range. Not time-critical, with the car at home and going nowhere? Then does the job.

Petrol in diesel queries from Burnhead motorists

Fuel drains on a Burnhead petrol station forecourt

Yes, and it's where a fair share of this work gets done. We work at another forecourt nearby and the other forecourts around town regularly, with the site's permission — tell us which one you are at when you phone and we will tell you if our technicians can work there.

Is there a safe quantity of petrol in a diesel?

Proportion decides it instead of litres — and more than either, whether the motor has run. Five litres in a nearly empty tank is a different matter from five in a full one — but either way, the thing that decides how much work is needed is whether that mixture has been drawn through your fuel system.

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

Stop safely. Off. Nothing after that. Driving takes the problem along — out of your tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one truly helpful thing left to you is not restarting the vehicle.

Fuel drains and manufacturer warranties

A drain then flush carried out correctly isn't an alteration and doesn't cancel a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another good reason to leave the car turned off.

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

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

A main dealer for petrol in a diesel — needed?

No. Our technicians drain and flush the vehicle wherever it is, so there is no need to bring it to a main dealer.

You, and the vehicle, still together?

Keep the engine switched off.

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

Clearing misfuelled cars, Burnhead and the rest of Aberdeenshire, wherever they are. Kerbside. Forecourt. Home.
