# Put Petrol in a Diesel Car in Canterbury?

If you have not fired up your engine as yet, do not. A drain and nothing else is nearly always what a vehicle needs while the fuel is still sitting in the tank and the engine has not run, which is why it's the coming few minutes that count, not how much got in. Petrol in Diesel goes to the vehicle wherever it has stopped in Canterbury or the rest of Kent, on the forecourt, by the roadside or on a private drive, and drains and flushes it there.

Just one ring our way is enough: our team can explain what happens next. Do it right away.

## What to try first about petrol in a diesel

- Don't crank it — and do not believe it when it runs. This is the thing most people have wrong about petrol in a diesel specifically. A petrol engine fed diesel typically just won't run, so the motorist stops and the wear halts with them. A diesel given petrol generally starts, ticks over and drives away without complaint for a couple of miles. It's not okay. It's wearing out your fuel system whenever you drive.

- Diesel ignites, and before it ignites it greases — the high-pressure fuel pump, the injectors. Petrol manages only the burning. So leave the ignition alone as well: switching it on is usually sufficient to prime your system, and priming pulls petrol from the tank into precisely those components.

- Do not dilute it. Diesel put on top removes nothing, so all you have is more of what was already there, since percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Still petrol. The grade makes no difference.

- Remain where you are if you safely can. A car that has not moved is the quickest one to sort out, and we'd much rather come to a tricky spot than have it started. If you're pulled up on the verge on Stour Street, put your hazards on and leave it there.

- Our van arriving instead of circling depends on two things: a postcode starting CT1 2, and whatever is nearest to you with a name on it. Get both ready before you dial.

- What went in, roughly how many litres, plus if the motor has started — these three details decide the entire job. Dial 0333 366 0103 and tell us.

## On a forecourt: removing petrol from your diesel

The job kicks off at the pump, usually. Quite often it finishes on site as well.

Still at Esso? Then that's usually where it takes place. Station forecourts are normal for us, with the agreement of the site.

The forecourt is the one place it can be stopped before your engine has run.

The few seconds between reading your receipt and going for the keys settle how much needs rinsing. Anywhere other than the forecourt — a car park, a driveway, a lay-by — the car was switched on and moved to get there, so fuel was sucked from the tank, through the filter and into your high-pressure pump. That means the lines and the filter require rinsing as well as your tank. It's not a disaster, and our engineers can still put it right where the car is.

Clear of the petrol pump, the next motorist can get by — so yes, let the staff help you wheel the car. Very much worth doing.

Firing it just to move four car lengths isn't.

If you've put petrol in your diesel BMW 3 Series around Canterbury and you're now sat at M&S Foodhall with a boot loaded with shopping, phone. Do not start the vehicle a second time to exit the space. We will come out to you, drain the tank, flush those fuel lines then put fresh diesel in so you can get home. A mile or so at light throttle pulls very little diesel, which is why these tend to be the simple cases.

## Parts our vans reach in Canterbury

Being a cathedral city, Canterbury gets a routine call, and the places round about come with it on that same journey: Northgate and St Dunstans, St Stephens and St Martins, Hales Place.

Our engineers do come. The places above are merely the immediate neighbours, and a page exists for the majority of towns across Kent, so an absence from the list isn't an absence from the coverage.

Close to a border, or somewhere your satnav struggles with? Contact us to ask rather than assuming.

The map outlines the patch this page covers.

Kerbside, forecourt, drive, car park: all of it is territory our technicians serve, and none of that asks the vehicle to move to us.

## Kerbside breakdowns around Canterbury

The chance to pull over anywhere sensible doesn't fall to everybody.

A common call for us and not an odd one: noticed after setting off, landed along the verge beside Best Lane or at a lay-by with your hazards on.

Fine right there? Remain by it. Not okay? Climb out and clear of it.

Do not start it up to reach a better place. It will go — a diesel on petrol generally obliges — and each mile of obliging drags that blend deeper into the fuel system.

Our van heading to a difficult place is no bother for us, and it's much better for the vehicle than carrying on.

It will fire up. It will drive off perfectly well. That's the issue, because a diesel on a thinned tank acts usually whilst wearing the components its fuel should be protecting. So no, never try the drive home from Cherry Tree — leave the Mercedes C-Class then phone.

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

The local M2 is the one which matters now, and runs under 10 miles from Canterbury.

It will usually take you onto it, and some way along, before you notice a thing. Then it is smoke, a rough idle and power falling away — not a tidy stop. Misfuelled diesels rarely give you one of those.

Pull off at the next sensible junction, switch off, and don't start it to reposition.

It alters what we bring, and so say so when you call: on a longer trip — anything approaching the under 25 miles to the nearest city — assume the mixture has been through the filter, your pump and the fuel injectors.

## Where is Canterbury?

Canterbury is a city situated in the county of Kent, in the South East region of England, and is located on the River Stour. Canterbury sits at an elevation of 17 metres, with the city's landscape dominated by the river and surrounding countryside. Canterbury has a mix of housing types, but semi-detached homes are particularly prevalent, and the city is close to nearby places such as Northgate, St Dunstans, and St Stephens. Canterbury is also within commuting distance of London, being approximately 54 miles away.

## Once our engineers reach you in Canterbury: what follows

- The responses shape the work, which is why our engineers ask before giving a price: what got in, how much of it, and whether your motor has run.

- The contaminated fuel is drawn from your tank.

- Fuel lines are purged through and the fuel filter cleaned, leaving nothing in your system that started any of this.

- Bleeding your system follows, once new diesel is in.

- When it's fired up, we check it runs smoothly on clean diesel.

From that point, you are ready to drive away.

Our engineers do all of this wherever the vehicle has stopped, which means it never needs to go to a garage, and when it has been noticed soon, it is very uncommon for there to be long-term damage.

Clearing your Vauxhall Astra, changing your filter where there is a serviceable one, cleaning the fuel lines, putting fresh fuel through the entire circuit: that is this job, and it is shaped by the worst of it sitting in the lines instead of in the tank by this point. Three things help when you call from near Geoffrey Chaucer — which side the filler is on, whether a technician can pull up alongside without blocking the road, and if your engine has run since you filled up. On-street is the commonest spot our engineers work, and so the location itself is rarely the trouble. A tight parking spot beats a car driven somewhere more handy.

## AdBlue in your diesel tank instead, around Canterbury?

If what was put in was AdBlue rather than petrol, the opening step is unchanged — don't fire it up — yet this problem is not.

Petrol thins your diesel and takes away the protection the fuel system depends on.

AdBlue? Urea dissolved in water. Put that in with your diesel and you get corrosion instead, plus deposits.

AdBlue removal in Canterbury has a page of its own with the details on it, including why it's usually the more significant of the two. Our engineers handle both.

Hire car or company car? Call them before you call us — some agreements want the hire firm to sign off the work, and sorting that out first is a great deal faster than sorting it afterwards. Then ring us about the Citroen C3 near The Beaney House of Art and Knowledge, and do not worry that you can't say how full your tank was. Nearly no one can, in a vehicle they collected two days ago, and our technicians work it out on site. The reason our engineers ask is that petrol in a diesel does its damage as a proportion: the same few litres in an almost empty tank is a far stronger blend than in a full one. Petrol is rated on how well it withstands igniting under pressure, which is the opposite of what a diesel needs — so the stronger that mixture, the more it rattles, smokes and goes flat.

## Canterbury prices for a petrol-in-diesel fuel drain

What moves the figure is listed below, as the job isn't one job and our engineers can't truthfully put a single number on this page.

- Has it been started or driven? Nothing else matters for as much.

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

- Which went in: petrol or AdBlue.

- Where is it? And can a technician reach it and work there safely?

The vehicle, the amount, whether it has run — give us those and the answer comes back clear instead of as a range.

For your car at home that's going nowhere and isn't urgent,  works too.

No dashboard light exists for this, which is why vehicles in that position typically get driven once more before anybody rings. Don't be one of them. The throttle went soft and your idle turned uneven after a couple of streets, and your diesel Volkswagen Touran is now sitting by Canterbury Library. Deadness there means fuel that can't build pressure properly rather than an engine failing. Turn off. Ring us.

## Things our technicians hear about petrol in diesel around Canterbury

## Fuel drains on a Canterbury petrol station forecourt

A large portion of this work gets done there, so yes.

Our technicians visit Morrisons and the other forecourts nearby routinely, with the station's permission — tell us which one you're at when you phone and we'll tell you whether our technicians can work there.

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

Proportion decides it instead of litres — and more than either, whether the motor has run.

What settles how much work is required is if that blend has been sucked through the fuel system — since even though five litres in an almost empty tank is a separate case from five in a full one, either way that is the query.

## I put petrol in my diesel and drove it. Now what?

Switch off somewhere sensible, then keep it that way after you stop.

It is salvageable much more frequently than drivers expect, even though driving is what moves the problem from the tank into your pump and injectors — and the single most valuable thing you can do now is not restart it.

## Will a fuel drain void my warranty?

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

Running a diesel on petrol is the thing more likely to cause an argument with one, which is another reason to leave the car switched off.

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

No. Two-stroke oil is an old remedy for a distinct fault and it doesn't put back what petrol has weakened.

Your tank still has petrol in it afterwards, and your pump still has to put up with it.

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

There is no need to bring it to a franchised dealer, because we drain and flush your car wherever it is.

## Standing next to it?

The engine stays off.

Switch it off somewhere safe and keep it off, if you have already driven it.

Cold and stationary, a vehicle is in the best position available — and drivers fear this much more than the recovery rate warrants.

Clearing misfuelled motors, Canterbury and the rest of Kent, wherever they are. Kerbside. Forecourt. Home.
