Put Petrol in a Diesel Car in Wollaston? Don't Start It
Petrol in Diesel drains and cleans misfuelled cars where they sit, on the forecourt, by the roadside or on a driveway, throughout Wollaston and the remainder of West Midlands. The first thing to do is not to fire up your engine. While your engine has not yet turned over and the petrol is still sitting in that tank, a tank drain is nearly always all it takes, and the coming few minutes decide that, not how much was put in. Phone so our engineers shall show you what comes next before you attempt anything else.
What next? Petrol in a diesel, in turn
- Don't crank it — and never rely on it if it starts. That is the thing most people get wrong about petrol in a diesel specifically. A petrol engine given diesel generally just can't run, and so the driver stops and the harm stops with them. A diesel given petrol generally starts, ticks over and moves off just fine for a few miles. It's not okay. It's eating into the fuel system as you drive.
- Flicking the car's ignition on frequently primes your system, and priming is what draws petrol out of that tank and into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it burns. Petrol manages the burning and none of the protecting. Leave the ignition alone.
- Topping up takes out nothing. It hands you a larger tank of the same mixture, since a diesel fuel system doesn't cope with petrol by percentage as that guidance presumes — so never tip diesel on top to weaken it. Grade is irrelevant too: super unleaded is petrol.
- Our team would sooner travel to an odd place than have it started — so if you safely can, stay still. Nothing is quicker to sort than a car that hasn't shifted. On the verge on Vicarage Road, that means hazards on and keep it.
- Before you phone, have your whereabouts. Anything next to you with a sign on it, plus a postcode beginning DY8 4 — that's what settles whether the van turns up or circles.
- Three answers settle the full job: the fuel you put in, the ballpark volume involved, and if anything has been running since. The number is 0333 366 0103.
The high-pressure fuel pump spent that morning run labouring on a fluid that had shed most of the protection it is built around. Diesel lubricates that pump, and the injectors with it, before any of the fuel ignites; petrol does the burning and none of the lubricating. So picture a diesel Volkswagen Golf, topped up at quarter past eight, taken in to work, and left sitting at Stourbridge Town till the penny drops close to eleven. Three hours of sitting have changed nothing about it. The couple of miles before that did a good deal, which is why the question our technicians ask you is about distance not hours. Call us. Leave it just where it is.
We are in car parks like the one outside Aldi a lot, and it's almost never your fuel that complicates them. It's the bay. Motors both sides. Trolleys stacked up behind. Occasionally a height limit at the way in, which decides whether a technician reaches you at all. So say how penned in you are when you ring, and which way your car is facing. If there is no clearance to work next to the Renault Clio, we move it without the engine. That's not fussiness over a handful of seconds: starts prime things, blend comes out of the tank toward your pump, and a motor moved twice for a better bay is quietly a worse job than one no one touched.
What we will ask about is if that trip there was short and cold, as that's where petrol is least likely to burn correctly — and whatever does not burn can work past the rings and into the engine oil. Right up to the moment someone drives it home, a diesel Ford Focus parked in the car park at The Princess carrying a tank of petrol in it is a simple job. Nothing degrades while it stands, so park it there overnight then phone in the morning.
Emptying your BMW 1 Series, changing the filter where there's a usable one, rinsing your lines, putting fresh fuel through the entire system: that's the job, and it's shaped by the worst of that resting in the lines rather than in the tank by this point. Three things help when you ring from close to Wollaston Evangelical Church — which side the filler is on, whether a technician can pull up alongside without blocking the road, and whether the engine has run since you filled up. On-street is the commonest place our engineers work, so the location itself is hardly ever the trouble. A tight parking space beats a motor driven somewhere more handy.
Cleared, not emptied — that's what a diesel Mercedes A-Class which got as far as Wollaston Methodist Church needs. Running a diesel puts the mixture into the filter, the fuel lines, your pump and its rail, none of which empties with that tank, so by now that tank holds the smaller part of the problem.
Pump-side drains for petrol in a diesel
A large portion of the work gets done at the pump, because that is where it usually begins. If you are still on the forecourt at the nearest petrol station, that's typically where the drain takes place — we work on petrol station forecourts all the time, with the owner's permission.
A filling station is the single spot the mistake gets caught before your engine has run. Our technicians can still put it right where it is, even away from the pumps. In a car park, on a driveway or in a lay-by, the car has been switched on and moved there, and that sucked fuel through the fuel filter and into the high-pressure fuel pump, all the way from the tank. None of that is a calamity, though the flush then has to go past the tank to your lines and your filter, and the few seconds between seeing the receipt and going for your key are what determine that.
Move the vehicle out of the way if the staff offer, and they normally will. The next motorist gets by the petrol pump, and that's worth doing. Starting it just to move four car lengths isn't.
Coverage near Wollaston
These same journeys take us to New Wood, Amblecote, Stourbridge, Wordsley and Norton as well as Wollaston, which is a residential suburb.
If yours isn't on that list it does not mean we never come — there are pages for nearly all towns in West Midlands, and the ones mentioned above are just the immediate neighbours. Assuming is the mistake to resist, above all on the border or anywhere your satnav fails. Ring us and check.
The map shows the ground this page covers. We operate at the roadside, on forecourts, on driveways and in car parks over all of that, and the vehicle does not need to travel to us.
Stranded by the roadside anywhere around Wollaston?
The chance to pull over anywhere sensible does not fall to everyone. If you realised after setting off and finished up along the verge on Somerset Drive, or in a lay-by somewhere with the hazard lights going, that is a routine call for us instead of an odd one.
Safe there? Sit with it. Not okay? Climb out and away from it. Do not fire up the motor to limp the vehicle somewhere safer — a diesel running on petrol will often oblige, and every mile it obliges for is drawing that mix further into your fuel system. A technician heading to an inconvenient place is no trouble for us, and it's a lot better for the car than carrying on.
Some miles on petrol in a diesel: now what?
under 10 miles out of Wollaston, your M5 is what counts now. It will often get you onto it, and some way along, before you spot a thing. Then it is some smoke, a lumpy idle and power ebbing away — not a neat stop. Wrongly fuelled diesels seldom give you one of those.
Don't restart it to move it. Get off at the first sensible junction then turn off. Long trip? Anything close to the under 10 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of that arrived at by the petrol. Say that on the phone, because it affects what goes in the van.
Where is Wollaston?
Wollaston is a suburban area in the West Midlands, situated on the riverside at an elevation of around 90 metres. Wollaston lies near the towns of Stourbridge and Amblecote, and is approximately 8.6 miles from Wolverhampton. Wollaston has a population of around 6901 people, predominantly living in semi-detached housing.
What comes next when we get to you in Wollaston
- Our engineers find out what was put in, how much, and whether your motor has run. The replies shape the work, which is why we ask before giving a price.
- Away goes the polluted fuel.
- Fuel lines are cleaned through and the filter cleaned, leaving nothing in the system that started any of this.
- Bleeding the system follows, once fresh diesel is in.
- Our engineers turn it on and confirm it runs properly on clean diesel.
That has the car ready to pull away. Our technicians do everything wherever the vehicle has come to a stop, which means it never has to go to a workshop, and when it has been spotted quickly, it is very uncommon for there to be long-term damage.
Wollaston AdBlue removal is a distinct job
The fault is not the same, though the opening rule is — never fire it up — if what got in was AdBlue instead of petrol. The lubrication a fuel system relies on gets stripped away by petrol, which thins the diesel. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get rust instead, plus residue.
Both are ours. There's a separate Wollaston page for AdBlue removal, with the full story on it — including the reasons it usually turns out to be the worse of the two.
Wollaston costs for a petrol-in-diesel fuel drain
Truthfully, no single number belongs on a page like this. This job differs. Here is what moves it:
- Started? Driven? Either answer counts more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel got into it.
- The sort of liquid in the tank, petrol or AdBlue.
- Access: the vehicle's position, and whether working on it there's safe for our van.
Tell us what the car is, how much got in, and whether the motor has run. A firm answer comes back, not a range. Car at home, going nowhere, nothing time-critical about it — is fine for that.
Wollaston drivers ask us these about petrol in diesel
At a petrol station around Wollaston, can you do a fuel drain there?
A fair share of this work happens there, so yes. Our technicians visit BP and the other forecourts around town regularly, with the station's permission — tell us which one you're at when you call and we will tell you whether our engineers can work there.
How much petrol in a diesel is too much?
It depends on the proportion rather than the litres, and far more on whether your engine has run. An almost empty tank with five litres in it, against a full one with the same five: distinct situations, certainly. Either way, the work needed comes down to one thing, which is if the fuel system has had that mix pulled through it.
Petrol in my diesel, and I have driven the vehicle
Stop safely. Off. Nothing after that. It's salvageable much more often than motorists fear, even though driving is what shifts the problem from the tank into the pump and injectors — and the single most helpful thing you can do now isn't restart it.
Fuel drains and manufacturer warranties
A manufacturer's warranty withstands a drain then flush done to a good standard, which is no modification at all. What's likelier to start a dispute is a diesel that has been run on petrol. One more reason for the motor to stay off.
Adding two-stroke oil, then driving home
Two-stroke oil solves a distinct fault, and an old one at that. Nothing it does puts back what petrol thinned. No. Your tank still has petrol in it afterwards, and your pump still has to live with it.
Main dealers and petrol in a diesel
There is no need to take it to a franchised dealer, because our engineers drain and clean your car wherever it is.
You, and your car, still together?
Your engine stays off.
Switch it off somewhere safe then keep it off, if you have already driven it. This is recoverable from much more commonly than people fear, and a parked, cold vehicle is the best place to be in.
Throughout West Midlands and in Wollaston: mobile fuel draining, at home or on the forecourt or at the kerbside.
