# Ladywood: Put Petrol in a Diesel Car?

If you have not started the motor yet, do not. A drain and nothing else is nearly always what a car requires while the petrol is still inside the tank and the motor has not yet run, which is why it is the following few minutes that matter, not how much was put in. Petrol in Diesel travels to your car wherever it has ended up in Ladywood or the rest of West Midlands, on the forecourt, by the roadside or on a private drive, and drains and flushes it there.

A single call to us is sufficient: our technicians will tell you what happens next. Make it straight away.

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

- Feed a petrol motor diesel and it will typically refuse to run at all, so the person stops there and so does the harm. Feed a diesel petrol and the car starts, it ticks over, it pulls away — fine enough for several miles. People have that reversed, which is the thing they get wrong about petrol in a diesel in particular. So don't start the car. And once started, do not believe it: your fuel system is wearing down whenever you drive.

- Flicking your ignition on commonly primes your system, and priming is what carries petrol out of that tank and into your pump and injectors. Those are the components diesel keeps lubricated on its way through, before it combusts. Petrol manages the burning and none of the oiling. Leave the ignition off.

- Topping up clears nothing. It leaves you a bigger tank of the same blend, since a diesel fuel system doesn't accept petrol by percentage as that advice presumes — so never pour diesel on top to dilute it. Grade is immaterial too: super unleaded is petrol.

- Stay where you are if you safely can. A motor that has never shifted is the easiest one to sort, and we would much rather get to an odd location than have it started. If you're stopped on the verge on Stoneleigh Close, put your hazards on then leave the vehicle there.

- Find out where you are before ringing. A postcode starting B74 2, and the name of whatever is closest to you. Otherwise the technician circles instead of showing up.

- Three facts decide the entire visit: the liquid you poured in, the approximate measure involved, and if it has been running since. The number is 0333 366 0103.

Petrol in a diesel Volkswagen Golf, sitting outside Four Oaks since first thing? The wait has lost you nothing — fuel sitting in a tank is inert. It was the drive in that drew diluted diesel through the pump. Phone us before you collect it.

## Clearing petrol from the diesel at the forecourt

Most of this work starts at a pump, which means a big chunk of that gets completed at one.

Still at Shell? Then that's normally where it happens. Garage forecourts are everyday for us, with the permission of the owner.

At a forecourt, this is caught with the engine never run, and no place else manages it.

The few seconds between checking the till receipt and going for your key settle how much requires flushing. Anywhere other than the forecourt — a car park, a private drive, a lay-by — the car was fired up and moved to get there, so fuel was drawn from your tank, through the fuel filter and into your high-pressure pump. That means the lines and the fuel filter need flushing as well as that tank. It is not a catastrophe, and our technicians can still sort it out where the vehicle is.

Clear of the pump, the next motorist can get by — so yes, let the staff help you push the vehicle. Very much worth it.

Four vehicle lengths isn't worth the risk.

Petrol in your BMW 3 Series, and it takes diesel? Shopping in your boot, you at M&S Foodhall, somewhere in Ladywood? Then ring us, and leave the engine out of that — not even to leave that bay. A technician comes to you. Tank drained, fuel lines flushed, new diesel in, and home you go. Easy throttle over a mile pulls very little, and so these are often the simple cases.

## Ladywood plus the villages beside it

Ladywood is a residential suburb, and our team go out to the town and to the places near it on the same journeys: Ley Hill, Four Oaks Park, Tudor Hill, Doe Bank and Moor Hall.

If yours is not on this list it does not mean we never come — there are pages for most places in West Midlands, and the ones listed above are simply the immediate neighbours.

Near a border, or anywhere your satnav gets wrong? Contact us to check rather than presuming.

Check this map for the patch included here.

Your car never needs to travel to us. We operate throughout all of it — roadside, forecourts, driveways, car parks.

## Stopped at the roadside somewhere in Ladywood?

Not everybody finds a safe spot to stop.

If you realised after setting off and ended up on the verge of Hartopp Road, or in a lay-by somewhere with the hazards on, that's a routine call for us instead of a rare one.

Safe right there? Sit by it. Not fine? Climb out and clear of it.

Don't restart it to reach a safer spot. It will go — a diesel on petrol normally obliges — and each mile of obliging pulls that mix deeper into the system.

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

Leave it overnight. Call us in the morning. Nothing about a diesel Audi A4 standing in the parking area by The Green House deteriorates as it waits, tank of petrol or not, and this job stays an easy one right up till the moment it gets driven home. The query we arrive with is about the run there: a cold motor over a short distance is where petrol combusts least well, and whatever fails to burn can get past the rings into the sump.

## Already driven it? Petrol in a diesel after a couple of miles

under 3 miles from Ladywood, your M6 Toll is what counts now.

A wrongly fuelled diesel will often take you onto it and some distance along before anything seems wrong, while the signs when they arrive are usually a drop in power, a lumpy idle and some smoke instead of a neat stop.

The first sensible exit is the one to take. Turn off there, and leave the restarting alone.

Suppose the worst of it on a long trip. Anything near the under 10 miles to the nearest city, and the mixture has been through the filter, through your pump, through your injectors. Say so when you call. What our technicians bring alters.

Diesel has to be thick enough to seal the tightly fitted parts it passes through, and petrol dilutes it. That is the whole mechanism, and it accounts for the usual Upper Nut Hurst call: a diesel Ford Focus that drove 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 needs the fuel to hold pressure, not just to burn — so when the fuel dilutes, pressure that should build and stay built starts escaping past tolerances instead, and your engine gets a weaker, 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 your fuel no longer acting like diesel, and it stops when the fuel is put right.

## A bit about Ladywood

Ladywood is a suburban area located on the riverside in the West Midlands, with an elevation of around 152 metres. Ladywood sits approximately 7 miles from Birmingham city centre and 103 miles from London. Ladywood is characterised by its predominantly detached housing stock and is near to several local amenities, including Ley Hill and Four Oaks Park. Ladywood is a relatively small community with a population of around 1073 residents.

## What follows when our engineers reach you in Ladywood

- We ask first, price after. What got in? How much? Has the engine run? Those responses shape what the work really is.

- Away comes the contaminated mixture.

- What is remaining in the system should not be what started the problem, so the fuel lines get cleaned and the filter cleaned.

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

- Our technicians start it and confirm it runs properly on new diesel.

That leaves your car ready to pull away.

Everything is done where your car is, so it never needs to be taken to a workshop, and when it has been caught quickly, long-term damage is very rare.

About as well as this goes, once the engine has turned: away from the pumps, receipt read, and your diesel Peugeot 3008 parked close to Four Oaks Methodist Church barely two streets on. Call us, then leave the vehicle off. A short hop does really help. It was still a start and still a drive, though, so the fuel filter and the pump have had weakened fuel through them — hence cleaning the fuel lines instead of only emptying that tank.

## A separate job: AdBlue in a diesel tank around Ladywood

If what went in was AdBlue instead of petrol, the opening instruction is unchanged — do not start it — but the problem isn't.

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

Urea dissolved in water, AdBlue, and in a diesel tank that brings rust and deposits.

Both are ours. There is a separate Ladywood page for AdBlue removal, with the full story on it — including the reasons it often turns out to be the worse of the two.

## How much is a petrol-in-diesel drain in Ladywood?

Truthfully, no single price fits on a page like this. This job changes. Here is what varies it:

- Whether your motor has been started or driven. This is the main one.

- How much of the wrong fuel was put in, against how much that tank holds.

- Whether it is unleaded or AdBlue.

- Whether a technician can sensibly reach the car and work on it, which depends on where your car is.

Tell us what your car is, how much got in, and if the engine has run. A firm answer comes back, not a range.

If it is not pressing — your car is at home and going nowhere —  is fine too.

## Ladywood drivers ask us these about petrol in diesel

## I am on a forecourt around Ladywood. Can you drain the car on the spot?

Much of what we do happens nowhere else. So yes.

Tell us which one you are at when you call and we will tell you whether we can work there. With the station's permission our engineers attend Texaco and the other forecourts nearby routinely.

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

Whether your engine has run matters much more, though the proportion matters too, rather than the litres.

Five litres in a nearly empty tank is a different matter from five in a full one — but either way, the thing that decides how much work is required is whether that blend has been sucked through the system.

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

Stop sensibly. Off. Nothing after that.

It's recoverable a lot more commonly than drivers assume, even though driving is what takes the problem from your tank into your pump and injectors — and the single most helpful thing you can do now is not restart it.

## My warranty — does a fuel drain void it?

It is not a modification, so a drain then flush carried out properly doesn't invalidate a manufacturer's warranty.

Another good reason to leave it switched off: running a diesel on petrol is the thing likelier to cause a disagreement with one.

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

What petrol has diluted isn't restored by two-stroke oil, which is an old fix for a different issue. So no.

Petrol remains in that tank later on, whatever else goes in, and the pump gets no break from it.

## Do I need a main dealer for petrol in a diesel?

You do not need one. The vehicle is drained and flushed wherever it is, with no need to take it to a franchised dealer.

## You, and the car, still together?

Turned off is how the car stays.

Switch it off somewhere safe then leave it off, if you have already driven it.

This is recoverable from much more frequently than people expect, and a stationary, cold vehicle is the best position to be in.

Call-out fuel draining around Ladywood and across West Midlands — at the kerbside, on the forecourt or at home.
