Put Petrol in a Diesel Car in Birch Green? Don't Start It
With that tank still holding the petrol and your engine not yet run, nearly every job needs only a drain, so keep the engine off. That outcome is decided in the minutes right after the fill-up, and not by the amount that was put in. All over Birch Green and the remainder of Surrey, Petrol in Diesel drains the vehicle and cleans it where it sits, whether by a roadside, on a driveway or at a forecourt. Phone before all else begins, so you will hear what happens after that.
What next? Petrol in a diesel, in order
- Feed a petrol engine diesel and it will generally fail to run at all, and so the person stops there and so does the wear. Feed a diesel petrol and the car starts, it idles, it drives off — all right for a couple of miles. Motorists have that reversed, which is the bit they get wrong about petrol in a diesel in particular. So don't start the car. And having started, never depend on it: that fuel system is grinding whenever you drive.
- Leave your ignition off as well. Diesel does two jobs: it combusts, and before it ignites it greases your high-pressure pump and its injectors. Petrol handles the first but not the second. Turning the car's ignition on is usually all it takes to prime that system, which carries the petrol out of your tank and into exactly those parts.
- Do not water down it. Diesel tipped on top gets rid of nothing, so all you have is more of what was already there, because percentage is not how a diesel fuel system accepts petrol. Super unleaded? Still petrol. The octane makes no difference.
- Our team would rather get to a tricky place than have it started — so if you safely can, stay still. Nothing is simpler to deal with than a motor that hasn't moved. On the verge on Moormede Crescent, that means hazards on then keep the car.
- Check where you are before ringing. A postcode that starts TW18 4, and the name of whatever is closest to you. Otherwise the van circles rather than arriving.
- Call 0333 366 0103. Anticipate three things — what went in, roughly how many litres, and if the motor has been started. Your replies determine whatever happens next.
The trip back would about double it, for no gain at all. One commute has already put a real volume of petrol-thinned diesel through the high-pressure pump of your Renault Megane. So keep the car where it stands. Ring us from the platform if that is easier — nobody needs you hovering over the vehicle outside Staines while our engineers work, and tonight trumps finding out on Monday.
Our technicians will head your way, empty the tank, purge the fuel lines then put new diesel in so you can head home. So if petrol went into your diesel Volkswagen Tiguan around Birch Green and you are stranded outside Co-op Food with a boot packed with shopping, call us — and don't fire it up a second time to exit that bay. A mile or so at gentle throttle pulls little fuel, which is why such jobs are often the simple jobs.
Injection pressure is the part being lost. Petrol thins diesel, and runnier fuel seeps past the tightly fitted parts that are meant to build that pressure, and so the further a diesel Mercedes E-Class went, the less well it held. Fine on the way out and gutless on the way back is how that drive to Moormede Recreation Ground went, then, and that tank is where to look. Stop somewhere safe, switch off then phone us.
Rarely the issue, the place. On-street is the most common place our technicians work, and a cramped parking spot is far preferable to a vehicle that has been driven somewhere more convenient. What does help, when you ring from near Bull Statue, is three things: the side the filler is on, whether a technician can pull up beside without blocking the road, and if anything has run since you filled up. Then the Kia Sportage gets cleared, the fuel filter changed where a serviceable one exists, the lines rinsed and fresh fuel put through the whole circuit — since by now the worst of it is in the lines, not your tank.
A few streets, then it stopped. Throttle soft, idle uneven, and your diesel Hyundai Tucson is parked up close to Spelthorne coat of arms mosaic. The motor isn't giving up — that sluggishness is fuel that won't build pressure. There's no light on the dash for it, and so motors like yours typically get driven again before anyone picks up the phone. Don't. Off, then phone us.
Can petrol be taken from a diesel at the forecourt?
A large portion of this job is completed at a pump, because that is where it often kicks off. The drain normally takes place there and then. Still on the forecourt at Shell? Given the site's consent, that is somewhere we work, and routinely.
At a forecourt, it is stopped with your motor never run, and no place else does it. The few seconds between checking your receipt and going for your key settle how much requires flushing. Anywhere other than the forecourt — a car park, a driveway, a lay-by — the vehicle was fired up and moved to get there, so fuel was drawn from the tank, through the filter then into the high-pressure fuel pump. That means your lines and the filter need flushing as well as that tank. It's not a calamity, and our technicians can still put it right where your car stands.
Staff will usually help out pushing it away from the pump, which lets the next driver get by. Welcome the assistance. Four vehicle lengths isn't worth a start.
Birch Green and the towns next to it
Those same trips get us to Staines-upon-Thames, Knowle Green, Egham Hythe, Church Lammas and Hythe End along with Birch Green, which is a residential suburb.
There are separate pages for the majority of locations in Surrey, and the ones named above are simply the closest neighbours — so yours being missing from that list tells you nothing about if our engineers come. Guessing is the habit to resist, above all on a boundary or anywhere your satnav goes wrong. Ring us to ask.
Check our map for the ground covered here. Our technicians work roadside, at forecourts, on driveways and in car parks across all of it, and your vehicle doesn't need to travel to us.
Kerbside stops across Birch Green
The chance to stop anywhere sensible does not fall to everybody. Set off, then twigged? Finished up on the verge of Furlong Road, or parked in some lay-by with the hazards flashing? That is a routine call here. Not an odd one.
Sit beside the motor if it is safe to wait in it, and clear of the vehicle if it's not. It will usually oblige. A diesel running on petrol limps along quite willingly, and that is the trouble: restart it to reach somewhere safer and the mix goes further into the system with every mile covered. A van heading to a tricky spot is no bother for us, and it is much better for your car than pressing on.
Driven it already? Pull over, and check this
Here is where the M25 matters, under 3 miles away from Birch Green. Some distance along, and onto it in the first place: a misfuelled diesel will frequently manage both before anything seems wrong. What you get then is seldom a neat stop. Power falls away, your idle turns uneven, and there may be smoke.
The first sensible junction is the one to take. Turn off there, then leave the restarting alone. Long drive? Anything near the under 25 miles to the nearest city and you should suppose the lot — filter, pump, injectors, all of it got to by the contamination. Say that on the phone, since it alters what goes in our van.
A bit about Birch Green
Birch Green is a suburban area in Surrey, situated near the lakes and rivers of the South East, with Staines-upon-Thames and Egham Hythe nearby. Birch Green has a relatively low elevation of 19 metres and is located approximately 17 miles from London. Birch Green is predominantly composed of flat housing, which is typical of many suburban areas in the region. Birch Green is close to several nearby places, including Knowle Green and Egham Hythe.
What comes next when our engineers get to you in Birch Green
- Three things get asked before any price — your fuel that went in, the quantity, and whether anything has been run since. Each answer changes the work.
- The contaminated mixture is pulled out of that tank.
- Fuel lines are rinsed through and the fuel filter cleared, leaving nothing in your system that created any of this.
- We put fresh diesel in and bleed the fuel system.
- Our engineers turn it on and check it runs properly on new diesel.
That leaves your car ready to drive away. There is no need for a workshop at any stage, since the work is all done where the vehicle is, and when it's caught early, long-term damage is very unusual.
Birch Green AdBlue removal is a distinct matter
The problem isn't the same, though the opening rule is — never fire it up — if what got in was AdBlue rather than petrol. The lubrication a fuel system depends on gets stripped away by petrol, which thins the diesel. AdBlue? Urea dissolved in water. Put that in with the diesel and you get rust instead, plus deposits.
Both are ours. There is a separate Birch Green page for AdBlue removal, with the full story on it — including the reasons it usually turns out to be the worse of the two.
How much is a petrol-in-diesel drain around Birch Green?
One figure wouldn't be fair here, as this is not one job. These are the things that move it:
- Has it been run or driven? Nothing else counts for as much.
- How much of the wrong fuel got in, set against how much your tank takes.
- The sort of fluid in the tank, unleaded or AdBlue.
- Whether a technician can safely get to your vehicle and work on it, which rests on where the vehicle is.
Tell us your car, the amount and whether it has run, and you will get a firm answer rather than a range. Not pressing, with your car at home and going nowhere? Then is fine.
Questions our engineers get about petrol in diesel in Birch Green
Can you do a fuel drain at a petrol station in Birch Green?
Plenty of what our engineers do takes place nowhere else. So yes. Agreement from the site is the condition. Given that, a forecourt like Sainsbury's is somewhere we're often enough, along with the rest of them locally — so name yours on the call and you will hear if working there's possible.
How much petrol in a diesel is too much?
It rests on the proportion instead of the litres, and much more on whether the motor has run. What determines how much work is required is whether that mixture has been pulled through the fuel system — because even though five litres in an almost empty tank is a different case from five in a full one, either way that's the query.
Petrol in my diesel, and I have driven the vehicle
Somewhere safe, then stop, then turn off and leave it off. It's fixable much more frequently than motorists assume, even though driving is what moves the trouble from your tank into your pump and injectors — and the single most valuable thing you can do now isn't restart it.
Is a fuel drain going to void my warranty?
A drain and flush carried out properly is not a change and doesn't void a manufacturer's warranty. What's likelier to start an argument is a diesel that has been run on petrol. One more good reason for your engine to remain off.
Two-stroke oil in that tank, and then home?
What petrol has thinned isn't replaced by two-stroke oil, which is an old workaround for a different problem. So no. Petrol stays in that tank later on, whatever else goes in, and your pump gets no break from it.
Main dealers and petrol in a diesel
You do not need one. Your car is drained and flushed wherever it is, with no need to bring it to a main dealer.
Is the car still with you?
Leave the car switched off.
Driven it already? Then somewhere sensible, stop, turn off, and no restarting it later on. Cold and parked, a motor is in the best place available — and motorists fear this much more than the recovery rate warrants.
