# Petrol in a Diesel Car in Cellarhill

Petrol in Diesel drains and flushes misfuelled cars where they stand, on the forecourt, by the roadside or on a driveway, across Cellarhill and the remainder of Kent. The very first thing to do is not to start your engine. While the engine has not run and the fuel is still inside that tank, a fuel drain is almost always all it needs, and the next few minutes settle that, not how much went in.

Ring us before anything else starts, and you'll know what follows from there.

## Your next five minutes: petrol in a diesel

- Don't fire it up. Started regardless? Then never depend on it. Diesel in a petrol car generally won't run, so the driver stops and the wear halts with them. Petrol in a diesel? It starts. It ticks over. It moves off normally, for a couple of miles. Drivers get that backwards. It is not fine — your fuel system is wearing down every mile you do.

- Switching your ignition on usually primes that system, and priming is what moves petrol out of your tank and into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it ignites. Petrol does the burning and none of the protecting. Leave the ignition be.

- Topping up clears nothing. It hands you a bigger tank of the same mixture, since a diesel fuel system will not tolerate petrol by percentage in the way that guidance suggests — so don't add diesel on top to thin it. Type is beside the point too: super unleaded is petrol.

- We'd sooner travel to an odd place than have it started — so if you reasonably can, stay still. Nothing is easier to sort out than a vehicle that has not shifted. On the verge on Pemberton Rise, that means hazards on then keep the car.

- The van arriving instead of circling rests on two things: a postcode that starts ME9 9, and whatever is next to you with a name on it. Get both ready before you phone.

- What got in, approximately how many litres, and whether your car has fired — those three facts shape the full call-out. Ring 0333 366 0103 and tell us.

## Clearing petrol from your diesel at the forecourt

Pumps are where this work usually kicks off, and where a large share of that closes.

The drain generally gets done right there. Still on the forecourt at Norton Cross Service Station? Given the station's permission, that is a spot we work, and regularly.

A filling station is the single place it gets halted before the motor has fired.

The few seconds between reading the till receipt and going for the keys determine how much needs rinsing. Anywhere other than the forecourt — a car park, a drive, a lay-by — the vehicle was fired up and driven to get there, so fuel was sucked from your tank, through your filter then into the high-pressure pump. That means your lines and the fuel filter need rinsing as well as the tank. It is not a catastrophe, and our engineers can still put it right where the vehicle is.

Staff will normally pitch in pushing it out from the petrol pump, which lets the next driver get through. Welcome the assistance.

Shifting it four bays doesn't justify cranking the motor.

Any start primes the fuel system and pulls more of that mix out of that tank and on to the pump — which is why a motor moved twice into a roomier bay has silently turned into a bigger job than one left precisely where it stopped. So if our technicians can't work alongside the diesel Renault Megane, our engineers move it without running it. None of that is fuss about a few seconds of running. Car parks like the one outside The Co-operative Food we visit often, and your fuel is hardly ever the awkward part: the bay is. Motors either side, a trolley shelter behind, sometimes a height limit at the way in deciding if our van can reach you at all. Tell us how penned in you are, and which way your car faces.

## Service around Cellarhill

These same journeys take us to Teynham, Barrow Green, Bogle, Teynham Street and Radfield as well as Cellarhill, which is a coastal area.

If yours isn't on this list it doesn't mean we do not come — there are dedicated pages for the majority of places in Kent, and the ones named above are just the nearest neighbours.

Ring us to enquire instead of assuming — county lines above all, and anywhere your satnav can get wrong.

This map outlines the area this page spans.

The lot is territory we cover: a roadside, a forecourt, a private drive, a car park. You do not bring your car anywhere.

## Cellarhill: stranded where you pulled up

Not everyone has a safe place to pull over.

A routine call for us instead of an unusual one: realised after setting off, finished up along the verge beside Nobel Close or in a lay-by with the hazard lights on.

Sit beside the car if it's sensible to wait there, but clear of it when it isn't.

Never start up the engine to nurse it somewhere handier — a diesel running on petrol will often oblige, and every mile it obliges for is drawing the mix further into your fuel system.

However inconvenient the location, it's no problem for us to get to it, and that's much better for the car than pressing on.

## Some miles on petrol in a diesel: what now?

Here is where the local M2 comes in — under 3 miles from Cellarhill.

A drop in power, a rough idle, some smoke: those are the symptoms when they appear, instead of a tidy stop — and a misfuelled diesel will often get you onto it and some way along before anything seems wrong at all.

The next safe exit is the one to take. Turn off there, then leave the restarting alone.

Presume the worst of that on a long drive. Anything close to the under 15 miles to the nearest city, and the petrol has been through the fuel filter, through the pump, through the injectors. Mention it when you call. What our technicians bring differs.

Your pump is not turning, so whatever your diesel Nissan Qashqai did on the way to Teynham Playing Fields, none of it is happening now. Nothing is getting worse while it stands. Take your time over this — but never drive it home to buy any.

## About Cellarhill

Cellarhill is a coastal locality in Kent, situated near the towns of Teynham and Canterbury, with semi-detached housing being the predominant type of accommodation. Cellarhill sits at an elevation of 23 metres, close to the Thames Estuary and approximately 42 miles from London. Cellarhill is part of a larger area that includes nearby places such as Barrow Green and Bogle.

## What our technicians do when our technicians reach you around Cellarhill

- Our engineers ask first, quote after. What was put in? How much? Has your motor run? Those replies change what the work actually is.

- Out comes the contaminated mixture.

- Our engineers clean the lines and clear your filter, and so what's left in the system isn't what started the issue.

- The fuel system gets bled, on new diesel.

- It is run with clean diesel in it, and our technicians confirm that it's running smoothly.

That has it ready to set off.

Our engineers do all of it wherever your car has stopped, which means it never needs to go to a workshop, and if it has been noticed early, it is very uncommon for there to be lasting damage.

The pump waits ahead of the fuel injectors, and so whatever a worn one gives off travels on with the fuel — which is why we're direct about not driving on. Ring us, then leave your diesel Audi A4 where it's near Teynham Village Hall.

## AdBlue in a diesel tank around Cellarhill is a different problem

The fault is not the same, though the opening instruction is — don't start it — if what was put in was AdBlue instead of petrol.

Petrol does two things to diesel: thins it, and removes the protection the fuel system relies on.

AdBlue is urea dissolved in water, and in a diesel tank it causes rust and residue instead.

Our technicians cover both, and AdBlue removal in Cellarhill has its own page with the details — including why it's usually the more significant of the two.

Petrol in a diesel does its harm as a proportion, which is the reason our technicians ask at all: the same few litres sitting in a nearly empty tank make a far stronger mixture 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 needs — so a stronger mixture rattles more, smokes more, goes flatter. None of which means you need an answer ready. Almost nobody knows how full the tank was in a vehicle picked up two days ago, and our technicians work that out on site. Do call the hire or company firm first, though: some agreements want them to sign off the work, and that's far quicker settled before than after. Then call us about the Mercedes E-Class close to St Mary.

## Paying for a petrol-in-diesel fuel drain around Cellarhill

What moves the figure is set out below, since the job is not one job and we cannot truthfully put a single figure on this page.

- Started? Driven? Either answer counts more than anything else on this list.

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

- The kind of fluid in the tank, unleaded or AdBlue.

- Access: the car's position, and if working on it there's sensible for our van.

The car, the amount, whether it has run — give us those and the answer comes back firm and not as a range.

Motor at home, going nowhere, nothing urgent about it —  is ideal for that.

A few streets, then it stopped. Throttle limp, idle ragged, and your diesel BMW 1 Series is parked up near Norton Village Hall. The engine is not failing — that deadness is fuel that will not build pressure. There's no light on the dash for it, so vehicles like yours generally get driven once more before anyone picks up the phone. Do not. Off, and ring us.

## Cellarhill drivers ask us these about petrol in diesel

## I am on a forecourt in Cellarhill. Can you drain the car here?

Yes — forecourts are where a fair share of this gets done.

Tell us which one you're at when you ring and we will tell you whether we can work there. With the station's permission we work at BP and the other forecourts nearby routinely.

## Is there a sensible amount of petrol in a diesel?

It depends on the proportion rather than the litres, and much more on whether your motor has run.

Five litres in an almost empty tank is a different matter from five in a full one — but either way, the thing that settles how much work is required is if that mixture has been sucked through your fuel system.

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

Somewhere safe, then stop, then switch off and leave it off.

Driving takes the problem along — out of your tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you is not restarting the car.

## Fuel drains and manufacturer warranties

No. Carried out correctly, draining and purging is no modification at all, and the warranty from your manufacturer is unaffected by it.

Running a diesel on petrol is the thing more likely to cause a disagreement with one, which is another good reason to leave it turned off.

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

Two-stroke oil solves a separate fault, and an old one at that. Nothing it does puts back what petrol thinned. No.

Petrol stays in that tank after that, whatever else goes in, and your pump gets no break from it.

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

No. We drain and flush your car wherever it is, so there's no need to bring it to a dealership.

## Standing next to it?

Your engine stays off.

Driven it already? Then somewhere safe, stop, switch off, and no restarting the vehicle later.

Cold, stationary, going nowhere: that is the best position to be in. Motorists fear this a lot more than they need to.
