Put Petrol in a Diesel Car in Hoe? Don't Start It
If you have not started your engine yet, do not. A drain and nothing more is almost always what a car needs while the fuel is still inside your tank and the engine has not turned over, which is why it's the next few minutes that matter, not how much got in. Petrol in Diesel travels to the car wherever it has ended up in Hoe or the rest of Surrey, on the forecourt, at the roadside or on a drive, and drains and flushes it there. One ring to us is enough: we can explain what comes after this. Try that right away.
Petrol in a diesel: what to do now
- Give a petrol motor diesel and it will generally not run at all, so the motorist stops there and so does the harm. Feed a diesel petrol and the thing starts, it ticks over, it pulls away — fine enough for a couple of miles. Most people have that muddled, which is the thing they get wrong about petrol in a diesel especially. So never start the vehicle. And if started, don't depend on it: that fuel system is wearing whenever you drive.
- Two jobs, diesel: it burns, and on the way through it keeps that high-pressure fuel pump and injectors greased. Petrol only does the one. Which is why the car's ignition stays off also — turn it on and you commonly prime the system, and that's petrol leaving your tank for precisely those components.
- Topping up gets rid of nothing. It gives you a fuller tank of the same blend, since a diesel fuel system won't cope with petrol by percentage in the way that advice assumes — so do not tip diesel on top to dilute it. Grade is beside the point too: super unleaded is petrol.
- Stay where you are if you safely can. A car that has not shifted is the quickest one to sort, and we would rather get to an odd location than have it started. If you are parked on the verge on Fulvens, turn your hazards on and leave it there.
- Have your position prepared before you call. A postcode that starts GU5 9 and whatever is closest to you with a sign on it is the difference between our van arriving and a van circling.
- Ring 0333 366 0103. Tell us what was put in, about how many litres, and whether the car has run. These three replies settle the full job.
Ring us before you collect the vehicle. Petrol into a diesel Volkswagen Golf this morning, and it at Gomshall ever since? Then the day has taken nothing from you: fuel in a tank is inert, and any harm came on the drive in, when the pump was pulling diesel that petrol had thinned.
The phone call our engineers like goes like this: diesel Renault Clio, a few litres of unleaded, run a couple of miles, now shut off outside Sainsbury's. What we are actually asking is how much fuel your pump has sucked — not how long ago it was.
A diesel BMW 3 Series parked in the parking area at Hurtwood Hotel holding a tank full of petrol in it is a straightforward job, right up until somebody takes it home. Leave the car there overnight and phone next morning. Nothing degrades whilst it stands. What we will ask is if that drive there was brief and chilly, because that's where petrol is least likely to burn correctly — and anything that won't burn can work past the piston rings and into the oil.
Clattering? Uneven idle? White smoke, throttle gone limp? That is your misfilled Audi A3, a diesel, saying what's wrong with it. Stop wherever you happen to be, possibly by St Mark's Church, and leave the restarting alone.
By now your tank is the least of it. Run a diesel and that blend goes into the filter, into the fuel lines, into the pump, into its rail — and none of that leaves with that tank contents. A diesel Vauxhall Astra that made it by Abinger Hammer Village Hall wants its circuit purged. Draining is not the same thing.
At a forecourt: draining petrol from the diesel
The job starts at a pump, mostly. Often enough it ends at one as well. Still at Esso? Then that is normally where it gets done. Garage forecourts are everyday for us, with the permission of the owner.
Nowhere but a garage can this be stopped with your motor still unrun. Our technicians can still sort it out where it is, even away from the forecourt. In a car park, on a driveway or in a lay-by, the vehicle has been started and moved there, and that drew fuel through your filter then into your high-pressure pump, right from that tank. None of that is a catastrophe, although the flush then has to reach past the tank to the fuel lines and the fuel filter, and the few seconds between seeing the receipt and reaching for your key are what settle that.
The attendants will usually happily roll the vehicle out from the petrol pump so the next driver can get past. That's worth doing. Cranking the car for four car lengths? No.
Will our engineers serve your corner of Hoe?
Hoe is a village, so our technicians head out to the town and to anywhere near it on the usual trips: Burrows Cross, Sutton Abinger, Smoky Hole, Peaslake and Abinger Hammer.
Our engineers still come. The names above are just the closest neighbours, and a page exists for nearly all locations across Surrey, and so an absence from the list is not an absence from the coverage. Call us and enquire rather than assuming — borders particularly, and wherever the satnav may struggle with.
This map marks the patch this page spans. Our technicians work by the road, at forecourts, on driveways and at car parks throughout all of it, and the vehicle does not need to come to us.
Roadside call-outs across Hoe
Some people have no sensible spot to pull in at all. A routine call for us and not an unusual one: noticed after setting off, landed by the verge on Sweet Lane or in a lay-by with the hazard lights flashing.
Whether you wait beside the motor or stand clear of it depends on if being there feels safe. Do not fire up your engine to limp the vehicle somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is pulling that blend further into the fuel system. We'll bring the van to an inconvenient place without any trouble, and for the car that is much better than driving on.
Driven it already? Pull in, then check this
This is where the local M25 comes into it — under 10 miles from Hoe. A misfuelled diesel will frequently get you onto it and some way along before anything feels wrong, and the signs when they arrive are usually a loss of power, an uneven idle and some smoke instead of a tidy stop.
Come off at the next sensible junction, switch off, and do not start the vehicle to move it. It alters what we bring, and so mention it when you phone: on a longer drive — anything approaching the under 25 miles to the closest city — assume the petrol has been through the fuel filter, your pump and your injectors.
Where's Hoe?
Hoe is a small village in Surrey, situated on the riverside at an elevation of around 130 metres. Hoe lies within the South East region of England, approximately 25 miles from London. Hoe is characterised by its predominantly detached housing and is close to nearby places such as Burrows Cross and Sutton Abinger. Hoe has a population of around 553 residents.
What we do when our technicians get to you in Hoe
- Three things get established before any quote — the fuel that got in, the quantity, and whether anything has been run since. Each answer alters the work.
- The tank gets cleared of it.
- Lines purged, filter cleared. Whatever remains later on is not the thing that created the issue.
- Bleeding your system follows, once new diesel is in.
- The engine is started and tested to confirm it runs properly on fresh diesel.
That has your car ready to drive away. All of it is done where the vehicle is, so it never needs to be taken to a workshop, and when it has been noticed soon, lasting damage is very uncommon.
A different problem: AdBlue in a diesel tank around Hoe
If what went in was AdBlue rather than petrol, the first instruction is unchanged — never start it — but this fault isn't. Petrol does two things to diesel: weakens it, and strips out the protection your fuel system depends on. Corrosion and build-up are what a diesel tank gets instead, since AdBlue is urea in water.
AdBlue removal around Hoe has a page of its own with the full story on it, including why it's usually the more serious of the two. Our engineers cover both.
What a petrol-in-diesel drain will cost in Hoe
What moves the figure is listed below, because this job is not one job and we cannot honestly put a single price on this page.
- Started? Driven? Either answer matters more than anything else on this list.
- How much of the wrong fuel got in, judged against how much the tank holds.
- AdBlue or petrol, whichever got in.
- Whether our van can safely reach your car and work on it, which depends on where your vehicle is.
A straight answer rather than a range is what you get for telling us three things: your car, the quantity, and whether it has run. If it's not urgent — the vehicle is at home and going nowhere — is fine too.
Hoe motorists ask us these about petrol in diesel
At a petrol station in Hoe, can you do a fuel drain there?
A large portion of this work happens there, so yes. Consent from the site is the condition. Given that, a forecourt like Shell is somewhere we are often enough, along with the rest of them locally — so name yours on the phone and you will hear whether working there is possible.
How much petrol in a diesel is too much?
Proportion settles it rather than litres — and more than either, whether your 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 mix been drawn right through, or has it not?
I drove the vehicle after putting petrol in my diesel. What next?
Stop sensibly. Off. Nothing after that. Driving moves the issue along — out of your tank, into the pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one truly useful thing left to you isn't restarting the car.
Will a fuel drain void my warranty?
No. Carried out correctly, draining and flushing is no change at all, and the warranty from your manufacturer is unaffected by it. Running a diesel on petrol is the thing likelier to cause a disagreement with one, which is another reason to leave it turned off.
Could I put some two-stroke in and just drive?
No. Two-stroke oil is an old workaround for a distinct fault and it does not replace what petrol has thinned. The pump still has to put up with it, since your tank still has petrol in it afterwards.
Do I need a main dealer for petrol in a diesel?
Wherever the vehicle is, we drain and flush it there, so a drive to the main dealer doesn't come into it.
Standing next to it?
Shut off is the way the car remains.
Already driven it? Then pull over somewhere sensible, switch off, and let it remain that way. A parked, cold car is the best position to be in, and this is recoverable from far more often than people expect.
