Petrol in a Diesel Car in Lower Higham
With that tank still holding the fuel and the engine not yet run, almost every job needs only a drain, so leave your engine off. That outcome is decided in the minutes straight after the fill-up, and not by the amount that got in. Across Lower Higham and the rest of Kent, Petrol in Diesel drains the car and flushes it where it is, whether by a roadside, on a private drive or at a forecourt. Contact us and our technicians can tell you what follows next before you attempt much else.
Petrol in a diesel: what to do next
- Don't crank it. Fired up anyway? Then never believe it. Diesel in a petrol car normally cannot run, and so the driver stops and the damage ends with them. Petrol in a diesel? It starts. It ticks over. It pulls away normally, for a couple of miles. People get that reversed. It isn't okay — the fuel system is grinding every mile you cover.
- Switching your ignition on often primes your system, and priming is what carries petrol out of your tank then into your pump and injectors. Those are the parts diesel keeps protected on its way through, before it burns. Petrol does the burning and none of the protecting. Leave your ignition alone.
- Topping up takes out nothing. It gives you a larger tank of the same mixture, since a diesel fuel system won't tolerate petrol by percentage in the way that guidance suggests — so never put diesel on top to weaken it. Type is immaterial too: super unleaded is petrol.
- Stay where you are if you sensibly can. A car that has not shifted is the quickest one to sort out, and we'd sooner come to an awkward spot than have it started. If you are pulled up on the verge on Chequers Street, turn those hazards on and keep the vehicle there.
- Find out where you are before ringing. A postcode that starts ME3 7, and the name of whatever is next to you. Otherwise the van circles rather than showing up.
- Three replies decide the entire visit: the fuel you poured in, the ballpark amount involved, plus whether anything has been turning since. The number is 0333 366 0103.
Quarter past eight. A hurried refuel on the way in. Somewhere around eleven it hits you, and by then your diesel Volkswagen Passat has waited at Higham for three hours. Phone then keep the car where it sits. What counts is the drive in, because diesel both combusts and — before that — protects the pump and the fuel injectors, but petrol only ever ignites. Those few miles ran the pump on a fuel stripped of a lot of its protection, and no quantity of sitting in a car park gives any of it back. Hence the question about distance instead of hours sitting, and hence the request to leave the keys where they are until our technicians arrive.
How much fuel your pump has sucked is what we're really asking — not how long ago any of it was. So the enquiry our technicians like goes like this: diesel BMW 3 Series, a few litres of unleaded, a couple of miles driven, now turned off outside jassal Superstore.
How far, and how hard? The second of those matters more than the first, and so have both ready. The Nissan Qashqai will have seemed entirely usual on the way back from Higham Primary School — they all do, and that is the snag. Diesel into a petrol motor mostly will not run at all: the driver stops, and so does the wear. Petrol into a diesel starts, ticks over, pulls away like nothing happened, whilst your high-pressure pump gets on with its work minus the lubrication your fuel should be giving it. No warning arrives, because behind the wheel nothing appears wrong.
Simple job, this one — until somebody takes it home. A diesel Audi A3 left outside Gardeners Arms with petrol in that tank loses nothing by standing there overnight, and so leave the vehicle then ring us once it is light. Expect a query about the run there, though. Brief and cold is precisely where petrol battles to burn, and what will not burn can get past the rings and into the oil.
Injection pressure is the thing being lost. Petrol dilutes diesel, and weaker fuel seeps past the precision parts that are supposed to build that pressure, and so the farther a diesel Vauxhall Astra went, the less well it held. Normal on the way out and flat on the way back is how that trip to Higham & Mockbeggar Cricket Club went, then, and that tank is the place to look. Pull over somewhere safe, turn off then call us.
Clearing petrol from your diesel on the forecourt
Forecourts are where this work mostly begins, and where a good portion of that ends. The drain typically happens on the spot. Still on the forecourt at Esso? Given the site's permission, that's a place our engineers work, and regularly.
At the forecourt, the mistake is spotted with the motor never started, and nowhere else does it. Fuel pulled out of your tank and through the fuel filter, all the way to your high-pressure pump, is what occurs when the motor is fired up and your car is moved to where it is now: the car park, the drive or the lay-by, anywhere other than the forecourt. So the flush covers the filter and your lines together with that tank. That is still not a disaster, and our engineers deal with it where your car stands. What determines it is whether the key was turned in the seconds after your receipt was read.
Away from the pump, the next driver can get past — so yes, let the staff help you push the car. Worth it. Four vehicle lengths is not worth the risk.
Lower Higham plus the areas near it
Being a coastal village, Lower Higham sees a routine visit, whilst the areas nearby come with it on that same trip: Church Street and Higham, Mockbeggar and Gadshill, Cliffe Woods.
Not on the list? That says nothing. The names above are only the nearest few, and nearly all locations across Kent have a page of their own somewhere on the site. Near the boundary, or somewhere your satnav struggles with? Ring us to check instead of guessing.
This map shows the ground this page covers. Roadside, forecourt, driveway, car park: the lot is territory we cover, and none of that asks your car to come to us.
Broken down by the roadside near Lower Higham
The opportunity to stop somewhere sensible doesn't come to everyone. A routine call for us rather than an unusual one: worked out after setting off, landed on the verge beside Lower Rochester Road or at a lay-by with the hazard lights going.
Out of the motor if it is not wise to sit there, with it when it is. Every mile a diesel obliges you for on petrol draws the mixture further into your fuel system — and oblige it often will, which is why the engine doesn't get restarted to limp somewhere handier. However awkward the place, it's no bother for us to get to it, and that is a lot better for the car than carrying on.
Run it already? Pull over, and check this
under 3 miles out of Lower Higham, the local M2 is what counts now. A wrongly fuelled diesel will usually get you onto it and some way along before anything seems wrong, and the symptoms when they arrive are normally a loss of power, a rough idle and some smoke instead of a tidy stop.
Don't start it to reposition. Come off at the first safe junction then switch off. Long drive? Anything close to the under 15 miles to the closest city and you should assume the lot — filter, pump, injectors, all of it reached by the petrol. Say that on the phone, as it affects what goes in our van.
Lower Higham itself
Lower Higham is a small village in north Kent, situated near the Thames estuary at an elevation of around 11 metres. Lower Higham lies within commuting distance of London, approximately 26 miles to the west, and is close to the nearby city of Southend-on-Sea. Lower Higham has a mix of housing types, with semi-detached homes being predominant in the village.
Once we reach you in Lower Higham: what happens
- We ask first, quote after. What got in? How much? Has your motor run? Those replies alter what the work actually is.
- Our engineers clear your tank of the tainted fuel.
- What is remaining in the fuel system shouldn't be what caused the issue, and so your fuel lines get cleaned and your filter cleaned.
- The fuel system gets primed, on fresh diesel.
- The motor is fired up and checked to make sure it runs smoothly on clean diesel.
That has the car ready to pull away. Everything is done where the car is, so it never has to be taken to a workshop, and when it has been noticed early, permanent damage is very rare.
Lower Higham AdBlue removal is a distinct job
The problem isn't the same, though the first instruction is — never start it — if what went in was AdBlue rather than petrol. Petrol does two things to diesel: thins it, and takes away the protection the system relies on. AdBlue is urea dissolved in water, and in a diesel tank it causes rust and deposits instead.
Both are ours. There's a separate Lower Higham page for AdBlue removal, with the full story on it — including the reasons it frequently turns out to be the worse of the two.
Lower Higham costs for a petrol-in-diesel fuel drain
Our technicians can't put one price on this page honestly, since the job is not one job. What shifts it:
- Has it been run or driven? Nothing else matters for as much.
- How much of the wrong fuel went in, measured against how much your tank holds.
- Whether it is petrol or AdBlue.
- Access: the vehicle's position, and if working on it there's safe for a van.
A clear answer rather than a range is what you get for telling us three things: the vehicle, the quantity, and whether it has run. If it isn't time-critical — your car is at home and going nowhere — is fine too.
Lower Higham motorists ask us these about petrol in diesel
At a petrol station in Lower Higham, can you do a fuel drain there?
Yes, and it's where a good part of this work happens. Tell us which one you are at when you phone and we will tell you if our technicians can work there. With the site's agreement we attend Asda Express and the other forecourts locally regularly.
A couple of litres of petrol in a diesel — too much?
Whether your engine has run counts much more, though the proportion counts too, instead of the litres. An almost empty tank with five litres in it, against a full one with the same five: different scenarios, of course. Either way, the work needed comes down to one thing, which is if the fuel system has had that mix sucked through it.
I drove the vehicle after putting petrol in my diesel. What next?
Stop somewhere sensible, turn off, then keep the car off. Not restarting it is the single most useful thing available to you now. Driving does shift the issue out of the tank and into your pump and injectors, yes, and it remains recoverable far more often than people assume.
Fuel drains and manufacturer warranties
No. Carried out correctly, draining and rinsing is no change at all, and the warranty from your manufacturer is unaffected by it. What is likelier to start an argument is a diesel that has been run on petrol. One more good reason for the motor to stay off.
Adding two-stroke oil, then driving home
No. Two-stroke oil is an old fix for a separate fault and it doesn't replace what petrol has diluted. Petrol stays in that tank after that, whatever else goes in, and the pump gets no break from it.
Main dealers and petrol in a diesel
There is no need to take it to a main dealer, because we drain and flush the car wherever it is.
Is the car still with you?
Never turn your engine on again.
Already driven it? Then pull over somewhere safe, switch off, and let the car remain that way. This is recoverable from far more regularly than motorists assume, and a stationary, cold motor is the best place to be in.
