Put Petrol in a Diesel Car in Fiddlers Green? Don't Start It
Petrol in Diesel drains and flushes wrongly fuelled cars where they stand, on the forecourt, by the roadside or on a driveway, throughout Fiddlers Green and the remainder of Gloucestershire. The first thing to do is not to fire up the motor. When the engine has not yet run and the fuel is still sitting in that tank, a drain is nearly always all it requires, and the following few minutes determine that, not how much got in. Ring us and our technicians can show you what follows next before you try much else.
Petrol in a diesel: what to try next
- Don't start the car — and never trust it when it starts. Here is the bit drivers have wrong about petrol in a diesel specifically. A petrol motor given diesel generally just cannot run, so the person stops and the damage halts with them. A diesel given petrol usually starts, idles and drives away quite happily for a few miles. It is not all right. It is grinding that fuel system while you drive.
- Switching the car's ignition on often primes your system, and priming is what draws petrol out of your tank and into the pump and injectors. Those are the parts diesel keeps oiled on its way through, before it burns. Petrol handles the burning and none of the lubricating. Leave the ignition off.
- Don't weaken it. Diesel tipped on top gets rid of nothing, and so all you get is more of what was already there, since percentage is not how a diesel fuel system handles petrol. Super unleaded? Simply petrol. The type makes no difference.
- Our team would rather drive to an awkward place than have it started — so if you safely can, stay still. Nothing is easier to sort than a motor that has never moved. On the verge on Beverley Croft, that means hazards on and leave it.
- Before you ring, get your location. Anything next to you with a sign on it, plus a postcode starting GL51 0 — that's what determines whether our van turns up or circles.
- What got in, approximately how much, and if your car has started — these three answers decide your whole visit. Dial 0333 366 0103 and tell us.
Draining petrol from a diesel on a forecourt
A good part of this work ends up completed at the pump, as that is where it often kicks off. The drain normally takes place on the spot. Still on the forecourt at Asda? Given the station's permission, that's somewhere we work, and routinely.
Before your engine has fired — the forecourt is the one place the mistake ends up stopped. We can still put it right where it stands, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been fired up and moved there, and that drew fuel through your filter and into the high-pressure pump, right from the tank. None of that is a calamity, but the flush then has to reach past your tank to your lines and the fuel filter, and the few seconds between checking your receipt and reaching for the keys are what determine that.
Roll the car out of the way if the staff offer, and they generally will. The next driver gets through the petrol pump, and that is worth doing. Four car lengths isn't worth a start.
Car parks like the one outside Asda are a place we visit frequently, and the fuel is rarely the complicated part. The bay is: vehicles either side, a trolley shelter behind, at times a height barrier on the way in that decides whether our van can get to you at all. So tell us how hemmed in you are when you ring, and which way the vehicle is facing. Where our technicians can't work beside the diesel Volkswagen Passat we will move the vehicle without starting it — and that is not fussiness about a handful of seconds of running. Any start primes the fuel system and pulls more of that mix out of that tank and towards the pump, so a car moved twice into a nicer space has silently become a harder job than one left exactly where it stopped.
Your diesel Nissan Qashqai will have seemed entirely ordinary on the way back from St Thomas More Catholic Primary School. They always do, and that is the trap with petrol in a diesel instead of the other way round. Put diesel in a petrol vehicle and it generally won't run, and so the driver stops and the wear stops with them. Put petrol in a diesel and it fires up, idles and pulls away as though nothing has happened — all the while the high-pressure fuel pump does its work without the protection your fuel is meant to be supplying. Nothing tells you, because from the driver's seat there is nothing to alert you about. Ring us with roughly how far you went and how hard you drove it; the second answer counts more than the first.
Injection pressure is the part being lost. Petrol weakens diesel, and runnier fuel seeps past the precision parts that are meant to build that pressure, and so the farther a diesel Audi A3 drove, the less well it held. Fine on the way out and flat on the way back is how that drive to Elm Farm Open Space went, then, and the tank is where to look. Pull over somewhere safe, turn off and ring us.
Hire car? Company car? Ring them before us. Some agreements want the firm to approve the work, and that is much faster dealt with up front than after that. Then ring us about the Vauxhall Astra, the diesel one, by YMCA. Don't worry that you can't say how full that tank was — nearly no one can two days into a motor, and it is something our technicians work out on site. The reason for asking: harm from petrol in a diesel is a matter of proportion. A couple of litres in a nearly empty tank make a far stronger blend than in a full one, and petrol is built to resist the very thing a diesel needs of that, which is igniting when compressed. Stronger mix, more knocking, more smoke, flatter throttle.
No warning exists for this, which is why motors in that position typically get driven a second time before anybody calls. Do not be one of them. The throttle went limp and your idle turned lumpy after a couple of streets, and the diesel Peugeot 2008 is now resting close to Hesters Way Community Resource Centre. Deadness there means fuel that can't build pressure fully instead of a motor giving up. Switch off. Ring us.
Fiddlers Green plus the places near it
As a residential suburb, Fiddlers Green sees a routine visit, whilst the areas nearby go with it on that same journey: Benhall and Springbank, Hesters Way and Hayden, Golden Valley.
Not on this list? That means nothing. The names above are simply the closest few, and most locations around Gloucestershire have a page of their own elsewhere on this site. Presuming is the mistake to resist, particularly on the boundary or somewhere a satnav fails. Ring us and enquire.
That map shows the patch the page spans. Roadside, forecourt, private drive, car park: the lot is territory our engineers cover, and none of that asks your car to travel to us.
Fiddlers Green: stranded where you pulled up
Not everyone has the chance to pull in somewhere suitable. Hazards flashing in a lay-by somewhere, or stopped on the verge beside Alder Court because you worked it out after setting off — our technicians take that call so often that it's the ordinary kind.
Out of the vehicle when it's not safe to sit there, with it if it is. Never fire up your motor to limp it somewhere better — a diesel running on petrol will frequently oblige, and every mile it obliges for is drawing that mixture further into the system. However inconvenient the location, it is no trouble for us to get to it, and that is much better for the vehicle than driving on.
Run it already? Pull over, then read below
This is where your M5 comes in — under 3 miles away from Fiddlers Green. Some way along, and onto it in the first place: a wrongly fuelled diesel will frequently manage both before anything feels wrong. What you get then is seldom a tidy stop. Power ebbs away, the idle gets uneven, and there may be some smoke.
Take the next exit that's safe, pull up there, and don't restart the car to move it. Assume the worst of it on a long trip. Anything near the under 10 miles to the closest city, and the petrol has been through your filter, through the pump, through the fuel injectors. Say so when you phone. What our engineers bring alters.

Our call-out around Fiddlers Green, step by step
- Our technicians check what went in, how much, and whether the motor has run. The responses alter the work, which is why our engineers ask before quoting.
- The polluted fuel is drawn out of the tank.
- What is remaining in the system should not be what created the trouble, so your fuel lines get rinsed and the fuel filter cleaned.
- New diesel goes in, and then your system gets bled.
- We start it and check it runs properly on clean diesel.
At that point it's ready to set off. All of it is done where your car is, so it never needs to go to a workshop, and when it has been caught soon, permanent damage is very rare.
AdBlue in your diesel tank instead, around Fiddlers Green?
If what was put in was AdBlue rather than petrol, the first rule is the same — don't start it — but the issue is not. Thinned diesel, and no lubrication left for your fuel system that relies on it. That is petrol. Urea dissolved in water, AdBlue, and in a diesel tank that leads to corrosion and deposits.
AdBlue removal around Fiddlers Green has a page of its own with the details on it, including why it is frequently the more serious of the two. Our engineers deal with both.
Budgeting for a petrol-in-diesel fuel drain in Fiddlers Green
Our engineers can't put one price on this page truthfully, as this job is not one job. What shifts it:
- This is the big one: whether your motor has been run, or driven.
- How much of the wrong fuel got in, judged against how much that tank takes.
- Whether it was unleaded or AdBlue.
- Where the vehicle is, and whether a technician can sensibly reach and work on it.
A firm answer instead of a range is what you get for telling us three things: the vehicle, the amount, and if it has run. If it isn't urgent — your car is at home and going nowhere — works too.
Petrol in diesel questions from Fiddlers Green motorists
I'm on a forecourt in Fiddlers Green. Can you drain it here?
A large portion of this work gets done there, so yes. Consent from the site is the condition. Given that, a forecourt like Esso is somewhere we are often enough, along with the rest of them locally — so name yours on the call and you will hear if working there is possible.
How much petrol is too much for a diesel?
It hinges on the ratio instead of the litres, and far more on whether the engine has run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same question in the end: has that blend been pulled right through, or has it not?
Already driven it with petrol in your diesel? What then?
Switch off somewhere sensible, then keep it that way after you stop. It's salvageable far more frequently than drivers assume, even though driving is what moves the issue from the tank into your pump and injectors — and the single most useful thing you can do now isn't restart it.
Will a fuel drain void my warranty?
No. Carried out correctly, draining and flushing is no alteration at all, and the warranty from your manufacturer is unaffected by it. Another good reason to leave it turned off: running a diesel on petrol is the thing more likely to cause an argument with one.
Two-stroke oil in the tank, and then home?
What petrol has thinned is not restored by two-stroke oil, which is an old fix for a separate issue. So no. That tank still has petrol in it later on, and your pump still has to live with it.
Main dealers and petrol in a diesel
Wherever your car is, our engineers drain and flush it there, so a visit to the main dealer doesn't come into it.
Standing next to it?
Leave it turned off.
Already driven it? Then pull over somewhere sensible, turn off, then let it remain that way. Cold, still, going nowhere: that's the best position to be in. Drivers fear this a lot more than they need to.
