Fratton: Put Petrol in a Diesel Car?
With the tank still holding the fuel and your engine not yet started, nearly every job needs only a drain, so leave your engine off. That outcome is settled in the minutes immediately after the fill-up, rather than by the amount that went in. All over Fratton and the remainder of Hampshire, Petrol in Diesel drains your car and cleans it where it sits, whether by a roadside, on a drive or at a forecourt. Contact us before anything else begins, and you will hear what happens from there.
Your first five steps: petrol in a diesel
- Don't crank it — and don't rely on it if it fires up. Here is the thing people have wrong about petrol in a diesel in particular. A petrol engine filled with diesel typically just cannot run, so the motorist stops and the harm stops with them. A diesel given petrol typically starts, idles and pulls away without complaint for a few miles. It is not all right. It's eating into that fuel system while you drive.
- Two jobs, diesel: it combusts, and on the way through it keeps that injection pump and injectors lubricated. Petrol only does the one. Which is why the ignition stays off also — switch it on and you frequently prime your system, and that's petrol leaving the tank for exactly those parts.
- That guidance assumes a diesel fuel system accepts petrol by percentage. It doesn't. Pour diesel on top and nothing at all is cleared; what you have is a larger tank of the same blend. And no, the type makes no difference — super unleaded is just petrol.
- Stay still if it's sensible to. Hazards on, engine off, leave the vehicle. Wherever you have stopped — the verge on Arundel Street, anywhere — an awkward place for us is better than a started diesel, and nothing is simpler for us to deal with than a car that never shifted.
- Find out where you are before calling. A postcode beginning PO1 1, and the name of whatever is nearest to you. Otherwise our van circles rather than arriving.
- What was put in, roughly how many litres, and also if your car has run — these three answers determine the entire call-out. Phone 0333 366 0103 and tell us.
The run in is what pulled weakened diesel through your pump. Sitting still has drawn nothing. Petrol in a diesel Renault Megane, left outside the nearest station all day, sits harmless in your tank whilst it waits. Phone us first — before the keys come out.
A diesel pump supplies fuel to demand, and a frantic morning drive asks for plenty — so three miles in the Ford Focus feels like nothing and is not. Twenty to nine by Arundel Court Primary Academy and Nursery, already late, the receipt in your hand showing unleaded: hazards on, engine off, ring us.
Pull over somewhere safe, turn off then call us. Normal on the way out to Landport Community Garden, gutless on the way back? Then look at the tank. Petrol weakens diesel; weaker fuel leaks past the tightly fitted parts that build injection pressure; and the farther your diesel Peugeot 3008 travelled, the less of that pressure it held.
Three things help when you ring from close to Fratton Community Centre: which side the filler is on, whether our van can park next to without blocking the road, and whether the motor has run since you filled up. On-street is the commonest spot our technicians work, and so the spot itself is hardly ever the problem — we'd much rather deal with a cramped parking space than with a vehicle that has been driven to somewhere more convenient. We'll drain your Audi A3, change your filter where there is a serviceable one, flush the lines and put fresh fuel through the entire circuit, since by this point the worst of it is resting in your lines instead of in that tank.
Hire car or company car? Call them before you ring us — some contracts want the hire firm to authorise the work, and sorting that out first is a great deal faster than sorting it after that. Then ring us about the BMW 1 Series by Fratton community centre, and do not worry that you cannot say how full the tank was. Nearly nobody can, in a motor they collected two days ago, and our technicians work it out on site. The reason our engineers ask is that petrol in a diesel does its damage as a share: 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 the mix, the more it knocks, smokes and goes flat.
Draining petrol from the diesel at the forecourt
Most of this work begins at the pump, which means a large part of that is completed on site. We work on garage forecourts all the time, with the owner's consent, and so if you are still at Asda that's generally where the drain gets done.
At the forecourt, this gets caught with the engine never started, and no place else manages it. Everywhere else — a car park, a drive, a lay-by — your car was fired up and driven to get there, which means fuel was sucked from your tank, through your filter then into the high-pressure fuel pump. That is not a disaster, and our technicians can still put it right where it sits. It does mean the lines and the fuel filter need cleaning as well as your tank, and that is determined by the few seconds between checking your receipt and reaching for the keys.
Attendants will normally chip in pushing it away from the petrol pump, which lets the next driver get by. Take the offer. Four car lengths isn't worth a restart.
Places our team cover in Fratton
Fratton is a residential suburb, and so we are out to the town and to the places around it on those same trips: Somers Town, Landport, Portsmouth, Kingston and Portsea Island.
Our technicians do come. The names above are merely the closest neighbours, and a page is there for the majority of places around Hampshire, so an absence from the list isn't an absence from the coverage. Ring us and check rather than assuming — county lines above all, and anywhere your satnav might struggle with.
The map is the area the page covers. Roadside, forecourt, driveway, car park: every bit of that is ground our engineers serve, and none of that requires your car to move to us.
Stuck by the kerbside anywhere around Fratton?
Not everyone has the chance to stop anywhere suitable. If you worked it out after setting off and finished up on the verge of Coburg Street, or at a lay-by somewhere with the hazards going, that is a routine call for us rather than a rare one.
Whether you sit beside your car or keep away from it depends on if staying there feels sensible. Never restart your motor to nurse it somewhere handier — a diesel running on petrol will frequently oblige, and every mile it obliges for is dragging that mix further into your fuel system. We will bring the van to a tricky place without any bother, and for your car that is far better than carrying on.
Petrol in a diesel, and your car has gone
Here is where the M275 comes into it — under a mile away from Fratton. Lost power, a rough idle, smoke: those are the signs when they come, instead of a tidy stop — and a wrongly fuelled diesel will frequently take you onto it and some way along before anything seems wrong at all.
The first sensible junction is the one to take. Turn off there, and leave the restarting alone. Long trip? Anything close to the under a mile to the nearest city and you should assume the lot — filter, pump, injectors, all of it reached by the contamination. Say that on the phone, since it alters what goes in the van.
Where is Fratton?
Fratton is a suburban area located on the southern coast of England, near the city of Portsmouth in Hampshire. Fratton sits at a low elevation of around 6 metres, close to the shoreline and adjacent to Somers Town and Landport. Fratton is predominantly composed of flat housing, reflecting its urban character and proximity to the city centre. Fratton is also situated near the major port city of Portsmouth, with which it is closely associated.
What follows when our engineers get to you around Fratton
- We ask first, price after. What was put in? How much? Has your engine run? Those replies alter what the work actually is.
- Out comes the polluted fuel.
- Fuel lines are flushed through and the fuel filter cleaned, leaving nothing in the system that started any of this.
- We pour fresh diesel in and prime the fuel system.
- It is started with new diesel in it, and our engineers make sure that it is running correctly.
Your car is then ready for you to pull away. We do everything wherever your car has come to a stop, which means it never has to be taken to a garage, and if it has been spotted quickly, it is very unusual for there to be permanent damage.
A distinct job: AdBlue in a diesel tank in Fratton
If what got in was AdBlue instead of petrol, the first step is unchanged — never fire it up — but this problem isn't. Petrol dilutes the diesel and removes the protection your fuel system depends on. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get corrosion instead, plus deposits.
Our technicians deal with both, and AdBlue removal around Fratton has its own page with the detail — including why it is often the more serious of the two.
Fratton costs for a petrol-in-diesel drain
What shifts the price is listed below, because this job is not one job and our engineers cannot honestly put a single price on this page.
- Whether the engine has been started or driven. This is the key one.
- How much of the wrong fuel went in, against how much that tank holds.
- Which was put in: unleaded or AdBlue.
- Access: the vehicle's position, and if working on it there is sensible for a van.
Tell us what the car is, how much went in, and if your engine has run. A firm answer comes back, not a range. If it isn't time-critical — the vehicle is at home and going nowhere — works too.
Things we hear about petrol in diesel in Fratton
At a petrol station in Fratton, can you do a fuel drain there?
Yes — forecourts are where a large part of this gets done. Agreement from the site is the condition. Given that, a forecourt like BP is somewhere we are often enough, along with the rest of them locally — so name yours on the phone and you'll hear if working there is possible.
How much petrol is too much for a diesel?
Ratio settles it instead of litres — and more than either, whether your engine has run. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, of course. Either way, the work needed comes down to one thing, which is if the fuel system has had that blend drawn through it.
I put petrol in my diesel and drove the vehicle. What next?
Somewhere safe, then stop, then turn off and leave it off. Driving moves the issue along — out of that tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really valuable thing left to you isn't restarting the vehicle.
Will a fuel drain void my warranty?
A manufacturer's warranty withstands a drain then flush done to a correct standard, which is no change at all. Running a diesel on petrol is the thing likelier to cause a disagreement with one, which is another reason to leave the vehicle turned off.
Two-stroke oil in the tank, and then home?
Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol weakened. No. Later? Still petrol in that tank, and a pump that has to cope with the stuff.
Main dealers and petrol in a diesel
There's no need to bring it to a main dealer, since our technicians drain and clean the vehicle wherever it is.
Still with your car?
Never switch your engine on again.
Turn it off somewhere safe then leave it off, if you have already driven it. Cold and stationary, a car is in the best place available — and people fear this much more than the recovery rate warrants.
Across Hampshire and in Fratton: on-site fuel draining, at home or on the forecourt or at the roadside.
