Put Petrol in a Diesel Car in Stonebridge? Don't Start It
If you have not fired up the motor as yet, do not. A drain and nothing more is nearly always what a motor requires while the petrol is still inside that tank and the engine has not been started, which is why it's the following few minutes that count, not how much was put in. Petrol in Diesel goes to your car wherever it has stopped in Stonebridge or the rest of Somerset, on the forecourt, by the roadside or on a driveway, and drains and flushes it there. Phone before everything else happens, and you'll hear what follows after that.
What now? Petrol in a diesel, in turn
- Don't crank it — and do not rely on it when it does start. That is the part most people get wrong about petrol in a diesel especially. A petrol engine filled with diesel typically just can't run, and so the driver stops and the wear stops with them. A diesel given petrol usually starts, ticks over and moves off just fine for several miles. It's not all right. It's eating into that fuel system while you drive.
- Turning the ignition on usually primes that system, and priming is what draws petrol out of your tank then into the pump and injectors. Those are the parts diesel keeps greased on its way through, before it combusts. Petrol manages the burning and none of the protecting. Leave your ignition off.
- Don't water down it. Diesel tipped on top gets rid of nothing, and so all you have is more of what was already there, since percentage is not how a diesel fuel system handles petrol. Super unleaded? Still petrol. The grade makes no difference.
- Remain where you are if you safely can. A vehicle that has not moved is the quickest one to deal with, and we would much rather come to an odd location than have it started. If you're stopped on the verge on Beaconsfield Way, switch those hazards on and leave it there.
- Before you ring, have your whereabouts. Anything nearest to you with a label on it, plus a postcode starting BA11 2 — that's what settles whether our van arrives or circles.
- Call 0333 366 0103. Anticipate three questions — what got in, approximately how much, and whether the engine has been turned over. Your replies decide whatever happens next.
The run in is what drew weakened diesel through the pump. Sitting still has pushed nothing. Petrol in a diesel Volkswagen Golf, parked outside Frome all day, sits harmless in the tank while it waits. Phone first — before your keys turn.
Nothing alerts you, since from behind the wheel there is nothing to be warned about. The diesel Peugeot 308 will have felt entirely normal on the way back from Hayesdown First School, and they all do — which is the snag with petrol in a diesel rather than the reverse. Diesel in a petrol motor usually refuses to run, stopping the driver and stopping the damage with them. Petrol in a diesel starts, ticks over, pulls away as though nothing had happened, and all the while your pump does its work without the lubrication its fuel is meant to supply. Tell us roughly how far, and how hard. The harder matters more.
Try the drive home from The Vine Tree? Don't. It will fire up and it will move off just fine, which is the issue — a diesel on a weakened tank behaves normally while wearing the components the fuel should be lubricating. Leave the Nissan Qashqai then phone.
Hire car or company car? Call them before you ring us — some contracts want the hire firm to approve the work, and sorting that out first is a great deal quicker than sorting it later. Then call us about the Citroen C3 near Frome Leisure Centre, and don't worry that you can't say how full that tank was. Nearly no one can, in a car they collected two days ago, and our engineers work it out on the spot. The reason our technicians ask is that petrol in a diesel does its harm as a ratio: the same few litres in a nearly empty tank is a far stronger mixture 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 that mix, the more it rattles, smokes and goes flat.
By now that tank is the least of that. Run a diesel and the mix goes into your filter, into the fuel lines, into the pump, into the rail — and none of that leaves with that tank contents. A diesel Mercedes GLC that made it near St Mary wants its circuit cleared. Clearing is not the same thing.
Can petrol be pumped from your diesel at a forecourt?
A fair part of this work gets finished at the pump, since that's where it usually starts. Still at Shell? Then that's normally where it takes place. Station forecourts are everyday for us, with the permission of the owner.
At a forecourt, it is caught with your engine never run, and no place else manages it. The few seconds between seeing your receipt and reaching for the key determine how much requires cleaning. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the car was switched on and driven to get there, so fuel was pulled from the tank, through the filter and into the high-pressure pump. That means your lines and the fuel filter require flushing as well as the tank. It is not a catastrophe, and our engineers can still deal with it where the car stands.
Staff will usually pitch in pushing it clear of the pump, which lets the next motorist get through. Take the help. Starting the car over four car lengths? No.
Stonebridge and the villages near it
Fromefield, Berkley Down, Oldford, Easthill, Innox Hill — every one of them on our trips that take us over to Stonebridge too, a residential suburb.
Not on the list? It says nothing. The names above are only the closest few, and most locations around Somerset have a page of their own elsewhere on the site. Contact us and check instead of presuming, especially when you are on a border or anywhere your phone misreads.
See our map for the ground covered here. The vehicle doesn't need to come to us. We work throughout the lot — kerbside, forecourts, driveways, car parks.
Stopped at the kerb somewhere in Stonebridge?
Some people have no sensible place to stop whatsoever. Hazards on at a lay-by somewhere, or stopped on the verge beside Maytree Close since you worked it out after setting off — we take that call so often that it's the normal kind.
Whether you remain beside the vehicle or keep away from it rests on if sitting nearby feels sensible. Every mile a diesel obliges you for on petrol drags that mix further into your fuel system — and oblige it frequently will, which is why your engine doesn't get restarted to limp somewhere better. Driving on does the vehicle far more harm than a van driving out to an awkward place, and that is no problem for us.
Already run it? Petrol in a diesel after some miles
This is where the local M4 matters, under 25 miles from Stonebridge. A wrongly fuelled diesel will usually get you onto it and some way along before anything feels wrong, while the signs when they appear are typically a loss of power, an uneven idle and smoke instead of a neat stop.
The next sensible junction is the one to take. Turn off there, then leave the restarting alone. On a longer run — anything near the under 15 miles to the closest city — assume the petrol has been through your filter, your pump and the fuel injectors, and tell us when you call. It changes what we bring.

What comes next when our technicians reach you around Stonebridge
- Our engineers ask first, quote after. What went in? How much? Has the engine run? Those responses shape what the work actually is.
- Away goes the tainted mixture.
- We flush the fuel lines and clean your filter, and so what is left in the system is not what created the problem.
- We pour clean diesel in and prime the fuel system.
- After it is started, we confirm it runs correctly on clean diesel.
That has it ready to set off. There's no need for a garage at any stage, as the work is all done where the car is, and when it's spotted early, permanent damage is very rare.
AdBlue in a diesel tank in Stonebridge is a separate job
If what got in was AdBlue rather than petrol, the first instruction is the same — don't crank it — but the issue isn't. Petrol dilutes your diesel and removes the lubrication your fuel system relies on. AdBlue? Urea dissolved in water. Put that in with your diesel and you get corrosion instead, plus residue.
Both are ours. There's a separate Stonebridge page for AdBlue removal, with the full story on it — including the reasons it often turns out to be the worse of the two.
Stonebridge pricing for a petrol-in-diesel drain
What moves the price is listed below, as the job is not one job and we can't frankly put a single figure on this page.
- This is the big one: whether the motor has been run, or driven.
- How much of the wrong fuel got in, compared with how much your tank takes.
- Whether it was unleaded or AdBlue.
- Whether our van can sensibly get to the car and work on it, which depends on where your car is.
Tell us your vehicle, the amount and if it has run, and you'll get a straight answer rather than a range. Car at home, going nowhere, nothing pressing about it — is fine for that.
Petrol in diesel questions from Stonebridge motorists
Fuel drains on a Stonebridge petrol station forecourt
Yes — forecourts are where a large part of this takes place. Tell us which one you are at when you phone and we'll tell you whether our technicians can work there. With the owner's consent we visit Texaco and the other forecourts around town routinely.
A few litres of petrol in a diesel — too much?
Proportion decides it instead of litres — and more than either, whether the motor has run. What determines how much work is needed is whether that mixture has been pulled through the fuel system — since even though five litres in a nearly empty tank is a distinct situation from five in a full one, either way that is the question.
Petrol in my diesel, and I have driven the car
Stop somewhere safe, turn off, then leave the vehicle off. Driving shifts the issue along — out of that tank, into your pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one truly valuable thing left to you isn't restarting the car.
Is a fuel drain going to void my warranty?
A drain and flush carried out properly isn't an alteration and does not cancel a manufacturer's warranty. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Could I put some two-stroke in and just drive?
No. It belongs to a distinct fault from a bygone era, and petrol has weakened something no oil of that kind restores. Your pump still has to live with it, since the tank still has petrol in it later on.
Does petrol in a diesel have to go to a main dealer?
Not at all. Our engineers drain and flush your car wherever it is, so there's no need to bring it to a dealership.
Standing next to it?
That engine stays off.
Switch it off somewhere sensible then keep it off, if you have already driven it. Cold, stationary, going nowhere: that is the best position to be in. Drivers fear this much more than they need to.
