Put Petrol in a Diesel Car in Watermead? Don't Start It
Don't fire up the motor. If the fuel is still in the tank and your engine has not run, a drain is almost always all it requires — and that's determined in the next few minutes, not by how much got in. Petrol in Diesel drains and flushes misfuelled cars where they are, across Watermead and the remainder of Gloucestershire, on the forecourt, by the roadside or on a drive. Ring us and then our technicians will tell you what happens next before you try much else.
Petrol in a diesel: what to do first
- Never fire it up — and don't depend on it when it runs. Here is the bit motorists get wrong about petrol in a diesel specifically. A petrol engine fed diesel typically just cannot run, and so the person stops and the damage ends with them. A diesel fed petrol usually starts, idles and moves off without complaint for a couple of miles. It isn't okay. It is eating into your fuel system as you drive.
- Flicking the ignition on usually primes that system, and priming is what pulls petrol out of the tank then into your pump and injectors. Those are the components diesel keeps lubricated on its way through, before it combusts. Petrol handles the burning and none of the protecting. Leave your ignition be.
- Do not put diesel on top to weaken it. A diesel fuel system won't accept petrol by percentage in the way that guidance presumes, and topping up takes out nothing — it merely leaves you a larger tank of the same mix. The grade makes no difference either: super unleaded is still petrol.
- Remain where you are if you reasonably can. A car that has not moved is the easiest one to handle, and our team would rather get to a tricky spot than have it started. If you're parked on the verge on Abbotswood Road, turn your hazards on then leave the car there.
- A van arriving instead of circling turns on two things: a postcode starting GL3 4, and whatever is closest to you with a name on it. Get both prepared before you phone.
- Dial 0333 366 0103. Expect three points — what got in, about how many litres, and if the motor has been run. The replies settle everything that happens next.
Tonight, please, rather than Monday. Taking it home is the one thing not to do: a commute has pushed real quantity through your pump already, petrol-thinned diesel and plenty of that, and the return leg would more or less double the figure to no purpose. The Volkswagen Golf can sit at Gloucester perfectly safely. Phone from the platform if quicker; standing over us while our technicians work is not necessary.
A diesel Mercedes E-Class parked in the car park outside Twelve Bells holding a tank of petrol in it is a simple job, right up till somebody drives it home. Leave the car overnight then phone next morning. Nothing deteriorates as it waits. What we will want to know is if that drive there was short and cold, since that's where petrol is least likely to burn properly — and what doesn't burn can work past the piston rings then into the sump.
Your pump rests before the injectors, and so whatever a worn-out one loses travels downstream with your fuel — which is why we're firm about not driving on. Call us, and leave your diesel Ford Kuga where it's by Saint Patrick's Catholic Church.
Hire car or company car? Phone them before you phone us — some contracts want the hire firm to authorise the work, and sorting that out first is a great deal quicker than sorting it after that. Then call us about the Peugeot 2008 near Brockworth Free Church, and don't worry that you can't say how full the tank was. Almost nobody can, in a motor they picked up two days ago, and we work it out on site. The reason our technicians ask is that petrol in a diesel does its harm as a share: the same few litres in an almost empty tank is a far stronger blend 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 the mixture, the more it rattles, smokes and goes flat.
By this point the tank is not where most of the damage is. Once a diesel has run, the blend is in your filter, the fuel lines, your pump and the rail — and it does not come back out with the tank contents. A diesel Citroen Berlingo that made it close to Brockworth And Witcombe Memorial needs the circuit cleared, not emptied.
Draining petrol from your diesel on the forecourt
A good share of this job ends up completed at a pump, since that is where it mostly begins. If you're still on the forecourt at Shell, that's normally where the drain happens — we operate on station forecourts regularly, with the owner's permission.
Before the motor has run — the forecourt is the only location the mistake is stopped. Fuel pulled out of your tank and through your filter, right to the high-pressure pump, is what occurs when your engine is fired up and your car is driven to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush takes in your filter and your lines together with that tank. That is still not a disaster, and our engineers put it right where your car stands. What decides it is whether the ignition was turned in the seconds after the receipt was checked.
Away from the pump, the next customer can get past — so yes, let the attendants help you move it. Very much worth it. Four vehicle lengths isn't worth a restart.
Areas our team cover near Watermead
As a residential suburb, Watermead sees a steady visit, while its neighbours round about come with it on that same round: Green Street and Coopers Hill, Brockworth and Henley, Little Witcombe.
If yours isn't on this list it does not mean we don't come — there are pages for most towns around Gloucestershire, and the ones listed above are simply the immediate neighbours. Guessing is the thing to avoid, especially on the boundary or anywhere a satnav struggles. Phone to check.
That map shows the patch this page spans. All of it is territory our technicians cover: a kerbside, a forecourt, a private drive, a car park. You do not drive your car anywhere.
Stranded on the roadside somewhere in Watermead?
Some drivers find no suitable spot to pull over whatsoever. A common call for us instead of an unusual one: noticed after setting off, ended up along the verge beside Oldfield Road or at a lay-by with the hazards flashing.
Whether you stay with the car or stand away from it turns on if being in it seems wise. It will often oblige. A diesel running on petrol limps along quite willingly, and that is the catch: restart the vehicle to reach somewhere better and that blend goes further into your fuel system with every mile driven. We'll send the van to an inconvenient location without any bother, and for the car that is much better than pressing on.
A couple of miles on petrol in a diesel: what now?
under 3 miles out of Watermead, the M5 is what counts now. A misfilled diesel will frequently take you onto it and some way along before anything feels wrong, while the signs when they arrive are generally a drop in power, a lumpy idle and some smoke instead of a tidy stop.
Take the next exit that's sensible, stop there, and never start it to reposition. It changes what our technicians bring, so tell us when you ring: on a longer trip — anything approaching the under 5 miles to the closest city — take it the mixture has been through your filter, the pump and the fuel injectors.
A little about Watermead
Watermead is a suburban area located near Gloucester in Gloucestershire, sitting at an elevation of 71 metres in the inland landscape of the South West region. Watermead is characterized by its semi-detached housing and is situated close to nearby places such as Green Street, Coopers Hill, and Brockworth. Watermead is a relatively small community, with a population of approximately 3257 residents, and is within a short distance of Gloucester, the nearest city. Watermead is also within a reasonable commuting distance to London, being around 89.9 miles away.
The visit around Watermead, step by step
- The replies alter the work, which is why our engineers ask before giving a price: what got in, how much of it, and whether your engine has run.
- The polluted fuel is drawn from your tank.
- Our technicians rinse your fuel lines and clean the fuel filter, so what's remaining in the system isn't what caused the issue.
- Fresh diesel goes in, and then the system gets primed.
- We start it and confirm it runs correctly on new diesel.
That has your car ready to set off. We do all of this wherever the vehicle has come to a stop, which means it never has to go to a garage, and when it has been noticed soon, it's very rare for there to be permanent damage.
AdBlue in a diesel tank in Watermead is a different problem
AdBlue instead of petrol? Then the opening instruction is unchanged — your motor remains off — whereas the fault underneath it's a separate one altogether. Petrol does two things to diesel: weakens it, and removes the protection the fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it brings corrosion and build-up instead.
Usually the more serious of the two, AdBlue — and the detail sits on its own Watermead page. Both are ours to deal with.
Watermead prices for a petrol-in-diesel drain
What shifts the figure is laid out below, as the job is not one job and our technicians can't frankly put a single figure on this page.
- Has it been started or driven? Nothing else matters for as much.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Which went in: unleaded or AdBlue.
- Whether a technician can sensibly get to the car and work on it, which depends on where the vehicle is.
The vehicle, the quantity, whether it has run — give us those and the answer comes back straight and not as a range. Car at home, going nowhere, nothing urgent about it — is ideal for that.
Petrol in diesel queries from Watermead drivers
I'm on a forecourt around Watermead. Can you drain it here?
A fair part of this work takes place there, so yes. Our engineers work at Tesco and the other forecourts locally all the time, with the site's permission — tell us which one you're at when you phone and we will tell you whether our technicians can work there.
Is there a sensible quantity of petrol in a diesel?
Ratio decides it instead of 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 blend been sucked right through, or has it not?
Already driven it with petrol in the diesel? Now what?
Turn off somewhere sensible, and keep it that way after you stop. Not restarting it is the single most useful thing available to you now. Driving does shift the trouble out of your tank then into your pump and injectors, yes, and it remains fixable much more often than people expect.
Will a fuel drain void my warranty?
A drain and flush carried out properly is not an alteration and does not cancel a manufacturer's warranty. What's likelier to start an argument is a diesel that has been run on petrol. One more reason for the motor to remain off.
Two-stroke oil in the tank, and then home?
What petrol has thinned is not put back by two-stroke oil, which is an old fix for a distinct issue. So no. That tank still has petrol in it later, and the pump still has to put up with it.
Main dealers and petrol in a diesel
Wherever the vehicle is, our technicians drain and clean it there, so a trip to the main dealer does not come into it.
Standing next to it?
Do not turn it on again.
If you have already driven it, pull in somewhere sensible, turn it off then keep it off. Cold and stationary, a car is in the best position available — and drivers fear this far more than the recovery rate warrants.
