# Put Petrol in a Diesel Car in Murston?

With that tank still holding the fuel and the motor not yet started, nearly every job needs only a drain, so keep the motor off. That outcome is determined in the minutes immediately after filling up, rather than by the amount that got in. All over Murston and the remainder of Kent, Petrol in Diesel drains the car and flushes it where it sits, whether at a roadside, on a drive or at a forecourt.

Contact us so we can tell you what follows after that before you try much else.

## Now what? Petrol in a diesel, step by step

- As you drive, your pump and the fuel injectors suffer. This is why you do not fire it up, and why you don't trust it once it has started. The trick about petrol in a diesel in particular — the bit most people get wrong — is that it pulls away normally for the first mile or two. Diesel in a petrol engine normally cannot run at all, which stops the person and stops the wear with them. This one lets you keep going.

- Two tasks, diesel: it ignites, and on the way through it keeps that high-pressure pump and injectors oiled. Petrol only manages the one. That is why your ignition stays off as well — flick it on and you usually prime your system, and that is petrol exiting the tank for exactly those components.

- That guidance assumes a diesel fuel system copes with petrol by percentage. It won't. Pour diesel on top and nothing at all is removed; what you get is a larger tank of the same mix. And no, the type makes no difference — super unleaded is still petrol.

- We would rather get to an odd place than have it started — so if you sensibly can, stay still. Nothing is simpler to sort than a motor that has not shifted. On the verge on Church Road, that means hazards on then keep it.

- Check where you are before calling. A postcode beginning ME10 3, and the name of whatever is next to you. Otherwise the van circles rather than turning up.

- Phone 0333 366 0103. Say what got in, roughly how much, plus if the engine has run. Those three answers settle the full call-out.

## Pump-side draining for petrol in a diesel

A large part of this work ends up done at a forecourt, because that's where it mostly kicks off.

Still at Asda? Then that is normally where it gets done. Station forecourts are normal for us, with the permission of the site.

At a garage, the mistake is stopped with your engine never run, and no place else manages that.

The few seconds between reading the receipt and going for your key settle how much needs cleaning. Anywhere other than the forecourt — a car park, a drive, a lay-by — the vehicle was switched on and moved to get there, so fuel was sucked from the tank, through your filter then into the high-pressure fuel pump. That means your lines and the fuel filter need rinsing as well as the tank. It is not a catastrophe, and our technicians can still deal with it where the vehicle sits.

Out from the pump, the next motorist can get by — so yes, let the attendants help you push it. Worth doing.

Cranking the car just to shift four vehicle lengths is not.

The difficult part is the bay, not your fuel. Motors either side of you, a trolley shelter behind, and now and then a height limit on the way in that decides if a technician can get to you at all — so when you phone from a car park like the one outside The Co-operative Food, say how much clearance there is about you and which way round the car is. Those our engineers cover often. Should there be no room to work alongside your diesel Skoda Octavia, it gets rolled with your engine off, and not out of fuss over a few seconds of running: priming takes place at every start, more of that mixture leaves your tank for the pump, and two shunts into a better spot have quietly made a worse job of what was just a vehicle sitting still.

## Will we serve your part of Murston?

As a residential suburb, Murston gets a frequent call, while the villages nearby go with it on the same journey: Snipeshill and Sittingbourne, Milton Regis and Tonge Corner, Bapchild.

If yours is not on this list it does not mean we never come — there are dedicated pages for nearly all places in Kent, and the ones listed above are just the closest neighbours.

Near a border, or anywhere a satnav struggles with? Call us to check instead of presuming.

That map outlines the ground this page spans.

Your car doesn't need to come to us. We operate over every bit of that — roadside, forecourts, driveways, car parks.

Twenty to nine. By Sunny Bank Primary School. Late already, and the till receipt in your hand says unleaded. Put the hazards on, leave your motor alone, and ring us. You may think three miles is nothing, in the BMW 3 Series or anything else — except that fuel is metered to demand, and a run taken in a hurry needs a great deal of it.

## Kerbside call-outs around Murston

The chance to pull in somewhere sensible doesn't fall to everyone.

Hazards flashing at a lay-by somewhere, or pulled onto the verge beside Hugh Price Close since you noticed after setting off — we take that call regularly enough that it's the ordinary kind.

Okay there? Wait beside it. Not safe? Move out and away from it.

It will often oblige. A diesel running on petrol limps along perfectly willingly, and that's the catch: fire it up to get to somewhere better and that blend goes further into your fuel system with every mile covered.

Pressing on causes the car far more harm than a van driving out to an inconvenient location, and that is no problem for us.

Try the trip home from The New Inn? Not a chance. It will fire up and it will move off just fine, which is the problem — a diesel on a thinned tank runs generally while wearing down the components your fuel should be lubricating. Leave the Peugeot 308 then ring us.

## Driven it already? Pull over, and read below

Your M2 is the one which matters here, and it lies under 5 miles from Murston.

It will often get you onto it, and some way along, before you feel a thing. Then it's some smoke, a lumpy idle and power falling away — not a tidy stop. Misfilled diesels seldom give you one of those.

Get off at the next safe exit, switch off, and do not restart the vehicle to move it.

It alters what we bring, so say so when you ring: on a longer drive — anything near the under 15 miles to the closest city — take it the contamination has been through your filter, your pump and the fuel injectors.

Diesel has to be viscous enough to seal the precision components it passes through, and petrol thins it. That's the entire mechanism, and it accounts for the ordinary Brickfields Community Garden call: a diesel Nissan Qashqai that travelled out there without complaint and came back down on power, lumpy at idle, perhaps smoking a little. A diesel injection system works hydraulically as well as chemically — it requires your fuel to hold pressure, not only to burn — so when the fuel thins, pressure that should build then stay built starts bleeding past tolerances instead, and the engine gets a poorer, later, less even delivery than it was designed about. No part of that is your engine failing, which is the bit worth hearing: it is the fuel no longer behaving like diesel, and it stops when the fuel is corrected.

## A little about Murston

Murston is a coastal suburban area in Kent, situated near the town of Sittingbourne and approximately 13.5 miles from Southend-on-Sea. Murston lies at a low elevation of around 12 metres above sea level, close to the Thames Estuary. Murston has a mix of housing types, but terraced houses are predominant in the area. Murston is also relatively close to London, at a distance of around 39.6 miles.

## When our engineers get to you around Murston: what we do

- Our engineers ask first, price after. What went in? How much? Has your engine run? Those replies alter what the work actually is.

- Out goes the polluted mixture.

- Our engineers rinse the lines and clear the filter, and so what is left in the fuel system is not what created the trouble.

- New diesel goes in, and then your system gets bled.

- It's started with fresh diesel in it, and our technicians check that it is running smoothly.

From there, you're ready to drive away.

Our engineers do all of it wherever the car has come to a stop, which means it never needs to be taken to a workshop, and when it has been caught early, it's very rare for there to be permanent damage.

## A separate matter: AdBlue in a diesel tank in Murston

Don't crank it: that opening step applies whether what was put in was AdBlue or petrol. What differs is this problem itself.

The protection a fuel system depends on gets taken away by petrol, which dilutes the diesel.

Urea dissolved in water, AdBlue, and in a diesel tank that causes corrosion and build-up.

Usually the more significant of the two, AdBlue — and the details sits on its own Murston page. Both are ours to handle.

Clattering? Ragged idle? White smoke, throttle gone soft? That is your wrongly fuelled Ford Kuga, a diesel, saying what is wrong with it. Stop wherever you happen to be, possibly close to Murston Old Church, then leave the restarting alone.

## How much is a petrol-in-diesel fuel drain in Murston?

What moves the figure is listed below, since this job is not one job and our technicians can't frankly put a single figure on this page.

- This is the key one: whether the motor has been run, or driven.

- Wrong fuel in, against what that tank takes — that ratio.

- AdBlue or unleaded, whichever was put in.

- Where your vehicle is, and whether a van can safely get to and work on it.

A straight answer rather than a range is what you get for telling us three things: the car, the quantity, and whether it has run.

For the car at home that is going nowhere and isn't pressing,  is fine too.

## Petrol in diesel questions from Murston motorists

## Fuel drains on a Murston petrol station forecourt

Yes, and it is where a good part of this work happens.

Tell us which one you're at when you ring and we'll tell you if our technicians can work there. With the owner's consent our technicians attend BP and the other forecourts locally routinely.

## A few litres of petrol in a diesel — too much?

Whether the motor has run counts much more, though the proportion counts too, rather than the litres.

Five litres into an almost dry tank is not five into a full one, no. But both land on the same query in the end: has that blend been pulled right through, or has it not?

## Petrol in my diesel, and I have driven the vehicle

Stop safely. Off. Nothing after that.

It's salvageable much more regularly than drivers expect, even though driving is what takes the problem from that tank into your pump and injectors — and the single most helpful thing you can do now isn't restart it.

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

It is not an alteration, and so a drain and flush carried out correctly doesn't invalidate a manufacturer's warranty.

Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause an argument with one.

## Could I put some two-stroke in and just drive?

No. It belongs to a separate problem from a separate era, and petrol has thinned something no oil of that kind restores.

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

## Does petrol in a diesel have to go to a main dealer?

There is no need to take it to a franchised dealer, since our technicians drain and flush your car wherever it is.

## Standing next to it?

Keep it turned off.

Driven it already? Then somewhere sensible, stop, turn off, and no restarting the vehicle afterwards.

Cold and still, a car is in the best position available — and people fear this much more than the recovery rate warrants.

Clearing misfuelled cars, Murston and the rest of Kent, wherever they are. Kerbside. Forecourt. Home.
