# Petrol in a Diesel Car in New House

Do not fire up the engine. While the fuel is still in your tank and your engine has not yet been started, a fuel drain is almost always all it takes — and that's settled in the following few minutes, not by how much was put in. Petrol in Diesel drains and cleans wrong-fuelled vehicles where they are, all over New House and the remainder of Kent, on the forecourt, at the roadside or on a driveway.

A single call our way will be plenty: our engineers can explain what comes next. Try it first.

## What now? Petrol in a diesel, in turn

- Give a petrol engine diesel and it will generally not run at all, and so the driver stops there and so does the damage. Feed a diesel petrol and the thing starts, it ticks over, it drives off — fine enough for a few miles. Drivers have that muddled, which is the bit they get wrong about petrol in a diesel especially. So never crank it. And if started, do not believe it: the fuel system is wearing down as you drive.

- Turning your ignition on commonly primes that system, and priming is what pulls petrol out of that tank then into your pump and injectors. Those are the components diesel keeps greased on its way through, before it ignites. Petrol handles the burning and none of the oiling. Leave the car's ignition alone.

- Don't thin it. Diesel added on top clears nothing, so all you have is more of what was already there, because percentage isn't how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The octane makes no difference.

- Remain where you are if you safely can. A car that has never moved is the simplest one to handle, and we'd sooner drive to an awkward place than have it started. If you are stopped on the verge on Dene Holm Road, switch your hazards on and leave it there.

- A van turning up instead of circling depends on two things: a postcode that starts DA11 8, and whatever is next to you with a sign on it. Keep both ready before you dial.

- Call 0333 366 0103. Let us know what got in, roughly how much, plus if the car has fired. These three facts decide your whole job.

## Forecourt draining for petrol in a diesel

Pumps are where this job usually starts, and where a good portion of it ends.

The drain generally gets done there and then. Still on the forecourt at Texaco? Given the owner's consent, that is a place we work, and regularly.

A forecourt is the single place it can be halted before your motor has fired.

Fuel sucked out of the tank and through the fuel filter, all the way to your high-pressure pump, is what occurs when your engine is started and the vehicle is driven to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush takes in the filter and your lines together with that tank. That's still not a disaster, and we deal with it where the car stands. What settles it is whether the key was turned in the seconds after the receipt was read.

Roll the vehicle out of the way if the staff volunteer, and they usually will. The next motorist gets through the petrol pump, and that's worth doing.

Four vehicle lengths isn't worth the risk.

How much fuel your pump has drawn is what we are actually asking — not how long ago any of it was. So the call our technicians want sounds like this: diesel BMW 3 Series, a few litres of unleaded, a couple of miles driven, now switched off outside Co-op Food.

## Do our engineers serve your side of New House?

The same rounds bring us to Wombwell Park, Pepper Hill, Perry Street, Kings Farm and Northfleet along with New House, which is a residential suburb.

There are dedicated pages for nearly all towns across Kent, and the ones named above are merely the nearest neighbours — so yours being left off this list means nothing about whether we come.

On a border, or somewhere your satnav can't find? Contact us and check rather than guessing.

Check our map for the ground covered on this page.

Roadside, forecourt, private drive, car park: every bit of that is ground we work on, and none of that requires your car to move to us.

Your diesel Peugeot 308 will have seemed entirely ordinary on the way back from Shears Green Infant School. They all do, and that is the snag with petrol in a diesel rather than the other way round. Put diesel in a petrol motor and it mostly won't run, and so the driver stops and the wear stops with them. Put petrol in a diesel and it starts, idles and moves off as though nothing has happened — all while the high-pressure fuel pump does its work without the lubrication your fuel is supposed to be giving. Nothing tells you, because from the driver's seat there is nothing to alert you about. Ring us with approximately how far you went and how hard you worked it; the second one counts more than the first.

## Kerbside stops around New House

Some drivers have no sensible spot to pull in whatsoever.

Set off, then noticed? Finished up along the verge of Coldharbour Road, or parked in some lay-by with the hazards going? That's a routine call here. Not an unusual one.

Safe there? Sit with it. Not safe? Move out and away from it.

Do not start it up to reach a safer location. It'll go — a diesel on petrol usually obliges — and each mile of obliging pulls that mix deeper into your fuel system.

A van coming to an awkward place is no problem for us, and it's a lot better for the car than carrying on.

## Run it already? Pull in, then read this

Here is where the M2 comes into it — under 5 miles away from New House.

A misfuelled diesel will frequently take you onto it and some way along before anything feels wrong, and the signs when they arrive are generally lost power, a lumpy idle and smoke instead of a neat stop.

Come off at the next sensible exit, turn off, and never start the car to reposition.

It affects what our engineers bring, and so say so when you ring: on a longer trip — anything approaching the under 25 miles to the closest city — take it the petrol has been through your filter, the pump and the injectors.

Never drive it home to buy yourself time. You already have it: nothing gets worse while the car stands, as a diesel Dacia Duster left outside Durndale Recreation Ground is doing none of what it did on the way there. The pump has stopped turning.

## A bit about New House

New House is a suburban area located on the coast of Kent, with an elevation of 37 metres, and is situated near several local parks and green spaces, including Wombwell Park and Pepper Hill. New House has a mix of housing types, but semi-detached homes are the most prevalent, and its proximity to Southend-on-Sea makes it a desirable residential location. New House is also relatively close to London, being approximately 21 miles from the city centre. New House has a population of around 8719 residents, according to recent estimates.

## What happens when our technicians reach you in New House

- Three things get checked before any price — your fuel that got in, the quantity, and if anything has been run since. Each answer changes the work.

- Our technicians drain the tank of the contaminated mixture.

- What is left in the system shouldn't be what created the problem, and so your fuel lines get cleaned and your filter cleaned.

- The fuel system gets primed, on clean diesel.

- After it's fired up, our engineers confirm it runs smoothly on clean diesel.

The car is then ready for you to pull away.

There is no need for a garage at any stage, because the work is all done where the car is, and when it is noticed quickly, permanent damage is very unusual.

## AdBlue in a diesel tank in New House is a separate job

AdBlue instead of petrol? Then the first step is unchanged — the engine stays off — while this problem under it is a distinct one altogether.

Petrol dilutes your diesel and removes the protection your fuel system depends on.

AdBlue is urea in water, and in a diesel tank it leads to rust and deposits instead.

AdBlue removal around New House has a page of its own with the detail on it, including why it's often the more serious of the two. We deal with both.

Petrol in a diesel does its harm as a ratio, which is the reason our engineers ask at all: the same few litres sitting in a nearly empty tank make a far stronger mix than they would in a full one. And petrol is rated on how well it resists igniting under pressure — the opposite of what a diesel wants — so a stronger mixture rattles more, smokes more, goes flatter. None of which means you need an answer prepared. Nearly nobody knows how full your tank was in a car picked up two days ago, and we work that out there. Do ring the hire or company firm first, though: some agreements want them to authorise the work, and that's far quicker settled before than after. Then call us about the Audi Q5 by Coldharbour Library.

## How much is a petrol-in-diesel fuel drain around New House?

We can't put one number on this page honestly, as the job isn't one job. What changes it:

- Has it been run or driven? Nothing else counts for as much.

- The tank's capacity, set against how much of the wrong fuel got into it.

- AdBlue or petrol, whichever went in.

- Whether a technician can safely reach your car and work on it, which rests on where the vehicle is.

Tell us your car, the quantity and whether it has run, and you'll get a straight answer instead of a range.

Not pressing, with your car at home and going nowhere? Then  is fine.

Someone confident will tell you to drain it then put clean diesel in. Half true, that. Try it on a diesel Vauxhall Insignia close to Nightingale Close Community Hall and the motor will start — which is precisely why it sounds like sense. Here is the problem: there is petrol left in the fuel filter and the feed lines, and the first thing your engine does is draw it back through the pump again. Draining a tank achieves nothing about fuel that already left that tank. Phone us. Your circuit gets cleaned, the filter comes off where there is one worth removing, and that's what separates a fixed vehicle from one that only starts.

## Petrol in diesel queries from New House drivers

## At a petrol station around New House, can you do a fuel drain there?

A good share of this work happens there, so yes.

Tell us which one you're at when you ring and we will tell you whether our engineers can work there. With the owner's agreement our technicians work at Morrisons and the other forecourts locally all the time.

## How much petrol in a diesel is too much?

Ratio decides it rather than litres — and more than either, whether the motor has run.

What determines how much work is required is if that mixture has been drawn through the fuel system — because though five litres in an almost empty tank is a separate situation from five in a full one, either way that is the query.

## I drove the vehicle after putting petrol in my diesel. What next?

Somewhere sensible, then stop, then switch off and keep it off.

Driving is what moves the issue from the tank into the pump and injectors — but it's fixable much more commonly than people fear, and the single most useful thing you can do now isn't restart the car.

## Is a fuel drain going to void my warranty?

It is not an alteration, so a drain and flush carried out correctly does not cancel a manufacturer's warranty.

What's likelier to start a disagreement is a diesel that has been run on petrol. One more good reason for the motor to stay off.

## Two-stroke oil in your tank, and then home?

No. It belongs to a different problem from a bygone era, and petrol has weakened something no oil of that kind puts back.

The pump still has to cope with it, because your tank still has petrol in it later.

## A main dealer for petrol in a diesel — essential?

Not at all. We drain and clean the car wherever it is, so there is no need to bring it to a franchised dealer.

## Standing next to it?

The motor remains off.

If you have already driven it, pull over somewhere safe, switch it off then keep it off.

This is recoverable from a lot more regularly than drivers assume, and a parked, cold motor is the best position to be in.

Across Kent and around New House: mobile fuel draining, at home or on the forecourt or at the roadside.
