Poolbrook: Put Petrol in a Diesel Car?
With your tank still holding the petrol and the engine not yet started, almost every job requires only a drain, so keep your engine off. That result is decided in the minutes immediately after filling up, rather than by the amount that was put in. Throughout Poolbrook and the remainder of Worcestershire, Petrol in Diesel drains your car and cleans it where it sits, whether at a roadside, on a driveway or at a forecourt. Contact us before everything else happens, so you will see what happens from there.
Your first five steps: petrol in a diesel
- Give a petrol engine diesel and it will usually fail to run at all, and so the person stops there and so does the harm. Give a diesel petrol and the car starts, it idles, it pulls away — all right for several miles. Motorists have that reversed, which is the part they get wrong about petrol in a diesel in particular. So never start the car. And if started, do not depend on it: that fuel system is wearing down whenever you drive.
- Diesel burns, and before it combusts it lubricates — the injection pump, those injectors. Petrol manages only the burning. So leave your ignition be also: flicking it on is frequently enough to prime the system, and priming carries petrol from your tank into just those parts.
- Topping up removes nothing. It gives you a fuller tank of the same mixture, because a diesel fuel system does not accept petrol by percentage as that guidance suggests — so never pour diesel on top to weaken it. Grade is immaterial too: super unleaded is petrol.
- Stay still if it is safe to. Hazards on, ignition off, keep the car. Wherever you have stopped — the verge on Geraldine Road, anywhere — an odd place for us beats a started diesel, and nothing is simpler for us to handle than a car that never shifted.
- Have your whereabouts prepared before you call. A postcode starting WR14 3 and whatever is closest to you with a sign on it is the difference between our van arriving and our van circling.
- Phone 0333 366 0103. Expect three questions — what was put in, roughly how much, plus whether the engine has been run. The answers determine whatever comes after.
The trip in is what pulled thinned diesel through the pump. Sitting still has drawn nothing. Petrol in a diesel Volkswagen Tiguan, left at Great Malvern all day, waits dormant in that tank while it waits. Phone first — before your keys come out.
Put diesel in a petrol car and usually it won't run, so the person stops there and the harm stops with them. Flip it — petrol into a diesel — and the thing fires up, ticks over and drives off as though nothing had happened, while your high-pressure pump works without the protection the fuel is supposed to be providing. That is the snag, and it's why the diesel Audi A4 will have seemed completely normal coming back from Great Malvern Primary School. They all do. From the driver's seat there's nothing to alert you about, so nothing tells you. Call us with approximately how far you travelled, and how hard; the second one matters more than the first.
Injection pressure is the thing being lost. Petrol thins diesel, and runnier fuel leaks past the close-fitting components that are supposed to build that pressure, and so the farther a diesel Mercedes C-Class went, the less well it held. Normal on the way out and flat on the way back is how the run to Chase Sports Pitch went, then, and that tank is the place to look. Pull over somewhere sensible, turn off and call us.
About as well as this goes, once the motor has turned: away from the pumps, receipt read, and the diesel BMW 5 Series left near Octagon hardly two streets on. Phone us, and leave the car off. A short drive does really help. It was still a start and still a drive, though, so the fuel filter and your pump have had thinned fuel through them — hence cleaning your lines instead of only draining that tank.
That deadness is the fuel failing to build pressure fully, not the motor giving up — and with no warning light for it, vehicles in that position normally get driven once more before anyone rings. Please don't. A couple of streets is all it got: throttle gone limp, idle turned lumpy, and a diesel Citroen C3 now sitting close to Sunshine Children's Centre. Switch the vehicle off and phone us.
On a forecourt: clearing petrol from a diesel
Much of this work starts at the pump, so a large portion of that ends up done there. We work on station forecourts routinely, with the station's agreement, and so if you're still at Gulf that is generally where the drain happens.
Nowhere other than the forecourt can it be stopped with the engine still unrun. The few seconds between seeing your receipt and reaching for your key determine how much needs cleaning. Anywhere other than the forecourt — a car park, a driveway, a lay-by — the car was started and driven to get there, so fuel was drawn from the tank, through the filter then into your high-pressure pump. That means the fuel lines and your filter require flushing as well as the tank. It's not a catastrophe, and our technicians can still sort it out where the car stands.
Away from the pump, the next driver can get by — so yes, let the staff help you move the car. Very much worth it. Firing the car to roll four vehicle lengths is not.
Places our vans reach in Poolbrook
These same trips carry us to Malvern Common, Barnards Green, Pound Bank, Sherrards Green and Hall Green along with Poolbrook, which is a residential suburb.
If yours isn't on the list that does not mean we don't come — there are dedicated pages for nearly all towns around Worcestershire, and the ones listed above are just the closest neighbours. Phone and enquire rather than presuming, above all where you are on the boundary or somewhere the satnav struggles with.
Check the map for the area included on this page. We operate at the roadside, at forecourts, on driveways and at car parks over all of it, and the car does not need to travel to us.
Poolbrook: stranded where you parked
Not everyone finds a decent place to pull in. Set off, then realised? Finished up on the verge on Bryony Close, or sat in some lay-by with the hazards on? That's a common call here. Not an unusual one.
Sit beside the vehicle if it's sensible to sit inside, yet clear of it when it's not. It will often oblige. A diesel running on petrol limps along perfectly willingly, and that's the catch: restart the car to get to somewhere better and the mix goes further into the system with every mile driven. A technician coming to a difficult location is no bother for us, and it's a lot better for the car than pressing on.
Petrol in a diesel, and the vehicle has travelled
This is where the local M5 matters, under 5 miles out of Poolbrook. It will often take you onto it, and some way along, before you spot a thing. Then it's smoke, an uneven idle and power draining away — not a clean stop. Wrongly fuelled diesels rarely give you one of those.
Don't restart it to move it. Come off at the next safe exit then turn off. It alters what our technicians bring, so tell us when you ring: on a longer run — anything near the under 10 miles to the nearest city — take it the mixture has been through your filter, the pump and the fuel injectors.
Poolbrook itself
Poolbrook is a suburban area located on the outskirts of Worcester in Worcestershire, situated near the River Teme at an elevation of around 50 metres. Poolbrook sits close to Malvern Common and other nearby places like Barnards Green and Pound Bank, forming part of the wider Worcester urban area. Poolbrook has a population of approximately 3005 people and is characterised by predominantly detached housing.
When our technicians reach you in Poolbrook: what we do
- The responses change the work, which is why our technicians ask before pricing: what was put in, how much of that, and whether the motor has run.
- The tainted fuel is pulled out of that tank.
- Our technicians purge your fuel lines and clean the filter, so what's left in your system isn't what created the trouble.
- Our engineers put fresh diesel in and prime the system.
- It's run with new diesel in it, and we check that it is running properly.
From there, you are ready to drive away. All of this is done where the vehicle is, so it never needs to go to a workshop, and when it has been spotted quickly, permanent damage is very rare.
AdBlue in your diesel tank by mistake, in Poolbrook?
The fault isn't the same, though the first step is — don't start it — if what got in was AdBlue instead of petrol. Petrol weakens your diesel and takes away the protection your fuel system depends on. AdBlue is urea in water, and in a diesel tank it causes rust and build-up instead.
Often the more serious of the two, AdBlue — and the detail sits on its own Poolbrook page. Both are ours to deal with.
What a petrol-in-diesel drain costs around Poolbrook
What moves the figure is listed below, since the job is not one job and our technicians can't frankly put a single number on this page.
- Started? Driven? Either answer matters more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel got into it.
- Which went in: petrol or AdBlue.
- Where the vehicle is, and if our van can safely reach and work on it.
The vehicle, the amount, whether it has run — give us those and the answer comes back straight instead of as a range. If it's not time-critical — your car is at home and going nowhere — works too.
Petrol in diesel queries from Poolbrook drivers
Can you do a fuel drain at a petrol station in Poolbrook?
A good portion of this work happens there, so yes. Tell us which one you are at when you call and we'll tell you whether our engineers can work there. With the site's permission our technicians attend Countrywide Farmers and the other forecourts nearby all the time.
How much petrol is too much for a diesel?
It hinges on the ratio instead of the litres, and far more on whether your engine has run. Five litres in an almost empty tank is a separate situation from five in a full one — but either way, the thing that determines how much work is required is if that blend has been pulled through the system.
I drove it after putting petrol in my diesel. What now?
Pull over somewhere sensible, switch off, and leave the vehicle off. Not restarting it is the single most valuable thing available to you now. Driving does move the trouble out of your tank and into your pump and injectors, yes, and it remains recoverable a lot more often than motorists assume.
Fuel drains and manufacturer warranties
A drain then flush carried out properly isn't a change and does not invalidate a manufacturer's warranty. What is likelier to start a dispute is a diesel that has been run on petrol. One more good reason for the motor to stay off.
Could I put some two-stroke in and just drive?
What petrol has weakened isn't replaced by two-stroke oil, which is an old workaround for a different fault. So no. Afterwards? Still petrol in your tank, and a pump that has to live with the stuff.
Main dealers and petrol in a diesel
Wherever the vehicle is, our engineers drain and flush it there, so a drive to the main dealer does not come into it.
Is the vehicle still with you?
Do not switch the engine on again.
If you have already driven it, pull in somewhere sensible, turn it off and leave it off. This is recoverable from a lot more frequently than people expect, and a stationary, cold car is the best position to be in.
