Put Petrol in a Diesel Car in Reigate?
With the tank still carrying the fuel and the motor not yet turned over, nearly every job takes only a drain, so keep the motor off. That outcome is decided in the minutes right after filling up, rather than by the amount that went in. Across Reigate and the rest of Surrey, Petrol in Diesel drains the car and flushes it where it stands, whether at a roadside, on a driveway or at a forecourt. We shall explain what the next part is. Contact us — that goes before anything else.
What to try now about petrol in a diesel
- While you drive, the pump and your injectors suffer. This is why you don't fire it up, and why you never trust it once it has started. The thing about petrol in a diesel in particular — the part most people get wrong — is that it drives away fine for the first mile or two. Diesel in a petrol engine generally won't run at all, which stops the driver and stops the damage with them. This one lets you drive on.
- Two things, diesel: it combusts, and on the way through it keeps your high-pressure pump and injectors oiled. Petrol only manages the one. Which is why your ignition is left off too — turn it on and you frequently prime your system, and that's petrol exiting the tank for just those parts.
- Topping up clears nothing. It hands you a fuller tank of the same mix, because a diesel fuel system does not handle petrol by percentage in the way that advice implies — so don't put diesel on top to water down it. Grade is irrelevant too: super unleaded is petrol.
- Wait where you are if you reasonably can. A vehicle that has not shifted is the simplest one to sort, and our team would rather get to an awkward location than have it started. If you are pulled up on the verge on Bell Street, turn those hazards on and leave it there.
- Find out where you are before ringing. A postcode that starts RH2 9, and the name of whatever is next to you. Otherwise the technician circles instead of arriving.
- Dial 0333 366 0103. Let us know what went in, roughly how many litres, and also whether the car has run. These three answers settle the full call-out.
Draining petrol from the diesel at the forecourt
It kicks off at the pump, typically. Frequently the work ends there too. Our technicians work on garage forecourts regularly, with the site's consent, and so if you are still at Esso that's generally where the drain happens.
Before your engine has started — the forecourt is the one place the mistake gets halted. The few seconds between reading your receipt and going for your key settle how much needs rinsing. Anywhere other than a forecourt — a car park, a driveway, a lay-by — your car was switched on and moved to get there, so fuel was drawn from the tank, through the fuel filter and into your high-pressure pump. That means the lines and the fuel filter require flushing as well as that tank. It is not a catastrophe, and our technicians can still put it right where the vehicle sits.
Clear of the pump, the next driver can get past — so yes, let the attendants help you roll it. Worth doing. Cranking it just to shift four vehicle lengths isn't.
How much fuel your pump has pulled is what we're really asking — not how long ago any of that was. So the phone call our technicians hope for sounds like this: diesel Peugeot 308, a couple of litres of unleaded, a couple of miles covered, now turned off at Morrisons.
Nothing tells you, as from the driver's seat there's nothing to be warned about. Your diesel Ford Focus will have seemed perfectly usual on the way back from Reigate Priory Community Junior School, and they all do — which is the catch with petrol in a diesel rather than the reverse. Diesel in a petrol motor usually refuses to run, stopping the motorist and stopping the wear with them. Petrol in a diesel starts, ticks over, pulls away as though nothing had happened, and all the while your pump works without the lubrication its fuel is supposed to supply. Tell us roughly how far, and how hard. The harder matters more.
Here's the whole mechanism. Diesel needs enough body to seal the close tolerances it goes through, and petrol takes that away. That's it. Which accounts for the normal Priory Park call — a diesel Mercedes A-Class, out there without fuss and back down on power, lumpy at idle, maybe a bit of smoke. Injection systems work hydraulically as well as chemically, so your fuel has to hold pressure and not just burn; weakened, it escapes past those clearances instead of building, and delivery comes poorer, later, less even than the motor was built about. Not a failing engine, though. Fuel that has stopped behaving like diesel. Put that right and it stops.
About as well as this goes, once your engine has turned: away from the pumps, receipt read, and the diesel Kia Sportage left near Old Town Hall scarcely two streets on. Call us, then leave the vehicle off. A short hop does truly help. It was still a start and still a drive, though, and so the filter and your pump have had diluted fuel through them — hence cleaning the fuel lines instead of only draining that tank.
Rattling, an uneven idle, white smoke, a throttle gone limp. That's a misfilled diesel Volkswagen Polo telling you what is wrong. Turn off where you have stopped, close to Brewery Yard Murals or anywhere else, and do not restart it to find a better location.
Will our technicians serve your side of Reigate?
Reigate is a riverside town, and so our team are out to the town and to the villages around it on those same journeys: South Park, Wray Common, Mead Vale, Skimmington and Reigate Heath.
Not on that list? That says nothing. The places above are only the nearest few, and nearly all places in Surrey have a page of their own somewhere on our site. On a border, or somewhere a satnav misreads? Contact us to enquire rather than presuming.
This map marks the ground this page spans. Our technicians work at the roadside, on forecourts, on driveways and at car parks over all of it, and the car never needs to move to us.
Stranded at the kerbside anywhere in Reigate?
The opportunity to stop somewhere suitable doesn't come to everybody. A normal call for us and not an unusual one: noticed after setting off, landed by the verge of Tunnel Road or in a lay-by with the hazards flashing.
Clear of the motor when it's not safe to be in it, by it if it is. Every mile a diesel obliges you for on petrol drags that mixture further into the system — and oblige it often will, which is why your motor doesn't get restarted to limp somewhere handier. Pressing on does your car far more harm than a technician coming out to an awkward location, and that is no bother for us.
A few miles on petrol in a diesel: what next?
This is where the M25 comes in, under 3 miles away from Reigate. A misfilled diesel will often get you onto it and some distance along before anything seems wrong, and the signs when they arrive are usually lost power, a lumpy idle and smoke instead of a tidy stop.
Take the next exit that is safe, stop there, and don't start it to reposition. Assume the worst of it on a long drive. Anything approaching the under 25 miles to the closest city, and the mixture has been through your filter, through the pump, through the fuel injectors. Say so when you phone. What our engineers bring alters.
Where's Reigate?
Reigate is a town in Surrey, situated on the banks of the River Mole, with a mix of old and new buildings. Reigate sits at an elevation of 86 metres, close to the North Downs, and is surrounded by areas such as South Park, Wray Common, and Mead Vale. Reigate has a population of around 16814 people, predominantly living in detached houses, and is located approximately 18.9 miles south of central London.
Our visit around Reigate, step by step
- Three things get established before any quote — the fuel that went in, the quantity, and whether anything has been run since. Each answer alters the work.
- We empty that tank of all the tainted fuel.
- Our technicians flush the fuel lines and clear the filter, so what is remaining in the system is not what caused the issue.
- Bleeding your system follows, once fresh diesel is in.
- It's run with new diesel in it, and our technicians confirm that it's running smoothly.
The car is then ready for you to pull away. We do all of it wherever the car has come to a stop, which means it never has to be taken to a workshop, and when it has been caught quickly, it's very unusual for there to be lasting damage.
Reigate AdBlue removal is a different job
AdBlue rather than petrol? Then the first rule is unchanged — the engine stays off — while the fault beneath it's a different one altogether. The protection a fuel system depends on gets stripped away by petrol, which thins your diesel. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get corrosion instead, plus deposits.
Our engineers handle both, and AdBlue removal around Reigate has its own page with the details — including why it is frequently the more significant of the two.
Reigate costs for a petrol-in-diesel drain
Truthfully, no single price fits on a page like this. The job changes. Here is what moves it:
- Has it been run or driven? Nothing else matters for as much.
- How much of the wrong fuel went in, weighed against how much your tank takes.
- The type of fluid in the tank, unleaded or AdBlue.
- Where is it? And can a van get to it and work there safely?
Tell us the car, the amount and whether it has run, and you will get a firm answer rather than a range. For your car at home that's going nowhere and is not time-critical, is fine too.
Reigate drivers ask us these about petrol in diesel
I'm on a forecourt in Reigate. Can you drain the vehicle on the spot?
Much of what our engineers do gets done nowhere else. So yes. Agreement from the site is the condition. Given that, a forecourt like Texaco is somewhere we are regularly, along with the rest of them locally — so name yours on the call and you will hear if working there is possible.
How much petrol is too much for a diesel?
Whether the motor has run matters far more, though the ratio matters too, instead of the litres. Five litres in an almost empty tank is a different matter from five in a full one — but either way, the thing that decides how much work is required is if that blend has been pulled through your fuel system.
Petrol in my diesel, and I have driven it
Stop somewhere sensible, turn off, and leave the vehicle off. Driving takes the trouble along — out of that tank, into your pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting the car.
Will a fuel drain void my warranty?
It's not an alteration, so a drain then flush carried out properly does not void a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing likelier to cause a dispute with one.
Can I just add two-stroke oil and drive home?
What petrol has diluted isn't restored by two-stroke oil, which is an old fix for a distinct problem. So no. Later on? Still petrol in that tank, and a pump that has to cope with the stuff.
Does petrol in a diesel have to go to a main dealer?
You do not need one. The vehicle is drained and flushed wherever it is, with no need to bring it to a dealership.
Standing next to it?
Leave it switched off.
Switch it off somewhere safe then leave it off, if you have already driven it. A stationary, cold vehicle is the best position to be in, and this is recoverable from far more regularly than motorists expect.
