New Street: Put Petrol in a Diesel Car?
With your tank still carrying the petrol and the motor not yet started, nearly every job takes only a drain, so leave the motor off. That result is determined in the minutes straight after filling up, and not by the amount that went in. All over New Street and the rest of Kent, Petrol in Diesel drains the car and flushes it where it sits, whether at a roadside, on a driveway or at a forecourt. Our engineers will show you what your next part is. Contact us — this happens before all else.
The next five minutes: petrol in a diesel
- Whenever you drive, your pump and the injectors wear. That's why you never start the car, and why you don't depend on it once it has started. The catch about petrol in a diesel in particular — the bit people get wrong — is that it drives away normally for the first mile or two. Diesel in a petrol motor normally will not run at all, which stops the motorist and stops the damage with them. This one lets you carry on.
- Diesel combusts, and before it burns it greases — your high-pressure pump, those injectors. Petrol does only the burning. So leave your ignition alone also: switching it on is usually enough to prime that system, and priming moves petrol from that tank into just those components.
- Never tip diesel on top to weaken it. A diesel fuel system doesn't cope with petrol by percentage the way that advice suggests, and topping up gets rid of nothing — it just leaves you a fuller tank of the same blend. The grade makes no difference either: super unleaded is simply petrol.
- Remain where you are if you reasonably can. A car that hasn't shifted is the easiest one to sort out, and our team would rather drive to an awkward location than have it started. If you're stopped on the verge on New Street Road, put those hazards on and leave it there.
- Before you dial, gather your whereabouts. Anything next to you with a label on it, plus a postcode starting TN15 7 — that's what settles whether our van shows up or circles.
- Ring 0333 366 0103. Let us know what got in, about how much, plus if the engine has started. These three details shape the whole call-out.
How far you drove is what our engineers query, not how long your motor has been standing — and here's why. Diesel does two jobs on its way through an engine: it combusts, and before burning it lubricates its injection pump and those injectors. Petrol manages the first only. So a hurried fill-up on the way in, the penny dropping close to eleven, and a diesel Renault Megane standing at Meopham since quarter past eight means those few miles were covered with your pump labouring on a liquid stripped of much of its protection. Phone us then keep the car right where it is.
Somebody will tell you to shift it out of the gateway and fix it later. Don't. A misfilled diesel Ford Focus on the zig-zags at Culverstone Green Primary School is a hassle; the same car restarted three more times to be helpful is a fuel system and not a tank. Every restart primes your lines and drags more petrol through the fuel filter then into your pump. Leave it, let everyone moan, then phone us.
Pull in somewhere sensible, switch off then call us. Normal on the way out to Meopham Green, flat on the way back? Then look at that tank. Petrol dilutes diesel; weaker fuel slips past the tightly fitted components that build injection pressure; and the farther the diesel Peugeot 3008 drove, the less of that pressure it held.
Phoning from close to Hodsoll Street and Ridley Village Hall? Three things help us. The filler — which side of your car it's on. Room for a van alongside you, without the road being blocked. And whether anything has run since the fill-up. The place itself hardly counts: on-street is where our engineers work most, and we would far rather have a narrow bay than a vehicle someone has driven somewhere simpler. Then it is a drain for the BMW 5 Series, a filter change where there's one worth changing, lines cleaned, clean fuel put round the entire circuit. By now the worst of it is in the lines and not the tank.
Authorisation first, where there's a hire firm or a company behind the vehicle — some contracts require it, and settling that beforehand saves a great deal of time later. After that, call us about the diesel Citroen C4 by St Peter. You will not know how full that tank was. Scarcely anybody does, two days into a motor, and it gets worked out on the spot regardless. Our engineers ask because the damage petrol does in a diesel is proportional: a couple of litres in a nearly empty tank make a much stronger blend than the same few in a full one, and since petrol is built to resist igniting under pressure, which is precisely what a diesel relies on, the stronger it gets the more the engine rattles and smokes and flattens off.
Can petrol be drained from a diesel on the forecourt?
A big chunk of this job gets completed at the pump, as that's where it often starts. Still at Texaco? Then that is generally where it happens. Station forecourts are everyday for us, with the consent of the station.
At a forecourt, it gets spotted with your engine never fired, and no place else does that. Fuel drawn out of your tank and through the fuel filter, right to your high-pressure pump, is what happens when your engine is started and the car is driven to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush covers your filter and the fuel lines along with the tank. That's still not a calamity, and we deal with it where your car sits. What determines it is whether the key was turned in the seconds after the till receipt was read.
The staff will generally offer to push the car clear of the petrol pump so the next motorist can get by. That's worth doing. Four car lengths isn't worth a start.
New Street and the towns near it
These same runs carry us to South Street, Culverstone Green, Ridley, Hodsoll Street and Meopham Green besides New Street, which is a rural hamlet.
Our technicians still come. The names above are just the immediate neighbours, and a page is there for nearly all places in Kent, so an absence from the list is not an absence from the coverage. Assuming is the mistake to avoid, above all on the border or somewhere your satnav goes wrong. Ring us to ask.
The map shows the ground the page spans. Kerbside, forecourt, drive, car park: all of it is ground our engineers cover, and none of that requires the car to travel to us.
New Street: stuck where you stopped
Not everyone has a sensible place to pull over. A routine call for us rather than an unusual one: realised after setting off, finished up along the verge beside Bunkers Hill or in a lay-by with the hazards flashing.
Whether you stay beside the vehicle or step clear of it depends on whether staying in it is wise. Every mile a diesel obliges you for on petrol draws the blend further into the fuel system — and oblige it usually will, which is why your engine doesn't get restarted to limp somewhere safer. Carrying on does the vehicle far more harm than our van driving out to a difficult location, and that is no bother for us.
So you've run it? Petrol in a diesel after a couple of miles
Here is where the local M20 counts, under 3 miles away from New Street. A loss of power, a rough idle, smoke: those are the signs when they appear, instead of a tidy stop — and a misfilled diesel will usually take you onto it and some way along before anything seems wrong at all.
Do not restart it to reposition. Get off at the first safe junction and turn off. Assume the worst of that on a long trip. Anything near the under 25 miles to the closest city, and the petrol has been through your filter, through the pump, through the fuel injectors. Say so when you phone. What we bring differs.
New Street itself
New Street is a small hamlet in Kent, situated inland at an elevation of around 155 metres. New Street lies near the villages of South Street and Culverstone Green, and is also close to Ridley. New Street is characterized by its predominantly detached housing stock and is located approximately 22.8 miles from London.
Our job around New Street, step by step
- We check what was put in, how much, and if your engine has run. The answers alter the work, which is why our engineers ask before pricing.
- The contaminated mixture is drawn from the tank.
- What is left in the system should not be what created the problem, so the fuel lines get flushed and the fuel filter cleared.
- Our engineers put fresh diesel in and bleed the system.
- We start it and confirm it runs properly on clean diesel.
That leaves it ready to set off. Lasting damage is very rare when it has been spotted early, and as all of this is done where the car is, it never needs to go to a workshop.
New Street AdBlue removal is a different job
If what got in was AdBlue instead of petrol, the opening instruction is the same — don't crank it — yet the issue isn't. The lubrication a fuel system depends on is stripped away by petrol, which dilutes the diesel. AdBlue? Urea dissolved in water. Put that in with your diesel and you get corrosion instead, plus deposits.
We cover both, and AdBlue removal around New Street has its own page with the details — including why it is frequently the more significant of the two.
Paying for a petrol-in-diesel fuel drain in New Street
Frankly, no single number fits on a page like this. This job differs. Here is what moves it:
- This is the big one: whether your motor has been run, or driven.
- The tank's capacity, set against how much of the wrong fuel got into it.
- AdBlue or petrol, whichever got in.
- Whether a van can sensibly get to your vehicle and work on it, which depends on where the car is.
The car, the quantity, whether it has run — give us those and the answer comes back clear instead of as a range. Not urgent, with the car at home and going nowhere? Then does the job.
Things our technicians get about petrol in diesel in New Street
I'm on a forecourt in New Street. Can you drain it here?
Yes, and it is where a big portion of this work takes place. Regularly, provided the site consents: Gulf, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that place is something our technicians answer straight away.
How much petrol in a diesel is too much?
Litres are not the measure. Ratio is, and far more than either, it counts if anything has been run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that blend been sucked right through, or has it not?
I drove the car after putting petrol in my diesel. What now?
Stop sensibly. Off. Nothing after that. Not restarting it is the single most useful thing available to you now. Driving does shift the trouble out of the tank then into your pump and injectors, yes, and it stays recoverable much more commonly than drivers expect.
Fuel drains and manufacturer warranties
It is not an alteration, so a drain and flush carried out correctly does not void a manufacturer's warranty. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Could I put some two-stroke in and just drive?
Two-stroke oil solves a distinct issue, and an old one at that. Nothing it does puts back what petrol thinned. No. The pump still has to live with it, as the tank still has petrol in it later.
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 dealership.
Waiting next to it?
Don't switch it on again.
Turn it off somewhere safe and leave it off, if you have already driven it. A parked, cold vehicle is the best position to be in, and this is recoverable from far more frequently than people fear.
