# Put Petrol in a Diesel Car in Handsworth Hill? Don't Start It

Don't turn on your engine. While the petrol is still sitting in that tank and the motor has not turned over, a fuel drain is almost always all it requires — and that gets determined in the coming few minutes, not by how much got in. Petrol in Diesel drains and cleans wrong-fuelled cars where they are, throughout Handsworth Hill and the remainder of South Yorkshire, on the forecourt, by the roadside or on a private drive.

Call us before everything else happens, and you'll know what follows after that.

## What to try now about petrol in a diesel

- Feed a petrol engine diesel and it will normally not run at all, so the driver stops there and so does the damage. Feed a diesel petrol and the engine starts, it idles, it drives off — all right for several miles. Drivers have that reversed, which is the part they get wrong about petrol in a diesel especially. So never crank it. And having started, do not rely on it: your fuel system is grinding as you drive.

- Leave the car's ignition be also. Diesel has two tasks: it ignites, and before it ignites it greases the injection pump and its injectors. Petrol handles the first but not the second. Turning the ignition on is commonly all it takes to prime your system, which moves the petrol out of the tank and into exactly those parts.

- Don't weaken it. Diesel added on top takes out nothing, and so all you have is more of what was already there, since percentage isn't how a diesel fuel system handles petrol. Super unleaded? Simply petrol. The octane makes no difference.

- Stay where you are if you reasonably can. A car that has not moved is the simplest one to handle, and our team would much rather travel to an odd place than have it started. If you are parked on the verge on Main Road, turn the hazards on then keep the car there.

- Before you call, get your whereabouts. Anything next to you with a label on it, plus a postcode beginning S9 4 — that is what determines whether the van arrives or circles.

- Three details settle the whole job: the stuff you tipped in, the rough quantity involved, plus if anything has been going since. Our number is 0333 366 0103.

Your high-pressure pump did that morning run working on a fuel that had shed much of the protection it is built around. Diesel greases that pump, and your injectors with it, before any of your fuel combusts; petrol does the burning and none of the oiling. So picture a diesel Renault Megane, topped up at quarter past eight, taken in to work, and parked sitting outside Darnall till the penny drops around eleven. Three hours of sitting have altered nothing about it. The few miles before that altered a lot, which is why the thing our technicians put to you is about distance not hours. Call us. Keep the car just where it stands.

## On the forecourt: draining petrol from the diesel

Pumps are where the work usually starts, and where a big share of it finishes.

If you're still on the forecourt at BP, that's usually where the drain happens — we work on station forecourts regularly, with the owner's consent.

No place but a forecourt can it be caught with your engine still unrun.

The few seconds between reading the till receipt and reaching for the keys settle how much needs flushing. Everywhere other than a forecourt — a car park, a private drive, a lay-by — the car was fired up and driven to get there, so fuel was drawn from your tank, through your filter and into the high-pressure pump. That means the lines and the filter need cleaning as well as the tank. It's not a catastrophe, and our technicians can still deal with it where your car stands.

The attendants will usually happily wheel the vehicle clear of the pump so the next driver can get through. That is worth doing.

Firing the car just to roll four vehicle lengths isn't.

The difficult part is the bay, not the fuel. Vehicles either side of you, a trolley shelter behind, and from time to time a height barrier on the way in that settles if a technician can get to you at all — so when you phone from a car park like the one outside Lidl, mention how much room there's round you and which way round the vehicle is. Those our technicians attend often. Should there be no space to work next to the diesel Volkswagen Passat, it gets shifted with the engine off, and not out of fuss over a couple of seconds of running: priming happens at every start, more of that blend departs the tank for your pump, and two shunts into a roomier bay have silently made a worse job of what was just a car sitting still.

## Handsworth Hill plus the areas beside it

Being a residential suburb, Handsworth Hill has a frequent visit, and its neighbours nearby go with it on the same run: Darnall and Greenland, Handsworth and Manor Estate, Richmond.

Not on this list? It says nothing. The places above are just the closest few, and the majority of places in South Yorkshire have a page of their own elsewhere on this site.

Close to a border, or somewhere your phone misreads? Phone and check rather than guessing.

The map is the patch this page spans.

We work by the road, on forecourts, on driveways and in car parks throughout all of that, and the car does not need to travel to us.

## Stranded on the kerb anywhere around Handsworth Hill?

Some people have no suitable spot to pull over whatsoever.

A normal call for us instead of an odd one: worked out after setting off, ended up by the verge of High Hazels Close or in a lay-by with the hazards on.

Remain beside the vehicle while it's safe to be inside, but clear of the car if it's not.

It will frequently oblige. A diesel running on petrol limps along perfectly willingly, and that's the problem: fire it up to reach somewhere safer and that mix goes further into the fuel system with every mile driven.

Our van coming to an inconvenient location is no bother for us, and it is a lot better for the vehicle than carrying on.

## Run it already? Stop, and check this

Your M1 is the road which counts here, and sits under 3 miles from Handsworth Hill.

Some way along, and onto it in the first place: a misfuelled diesel will usually do both before anything seems wrong. What you get then is seldom a tidy stop. Power drains away, your idle goes rough, and there may be smoke.

Get off at the next sensible exit, switch off, and never restart the car to move it.

Assume the worst of it on a long run. Anything near the under 3 miles to the closest city, and the petrol has been through the filter, through the pump, through the injectors. Mention it when you call. What our engineers bring differs.

## All about Handsworth Hill

Handsworth Hill is a suburban area in South Yorkshire, situated near the River Don and close to the city of Sheffield. Handsworth Hill has a mix of housing types, but semi-detached homes are the most prevalent, and its elevation is around 81 metres above sea level. Handsworth Hill is located near several other suburbs, including Darnall and Greenland, and is about 2.7 miles from Sheffield's centre.

## When we reach you around Handsworth Hill: what follows

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

- Out goes the tainted fuel.

- What is remaining in the fuel system shouldn't be what started the trouble, and so your fuel lines get flushed and your filter cleared.

- Our technicians pour new diesel in and bleed your system.

- Our engineers start the car and check it runs smoothly on new diesel.

From that point, you are ready to drive away.

Lasting damage is very rare when it has been spotted quickly, and because all of this is done where your car is, it never needs to go to a workshop.

Seldom the problem, the location. On-street is the commonest spot our engineers work, and a cramped parking space is far preferable to a car that has been driven somewhere more convenient. What does help, when you phone from close to Church of Jesus Christ Apostolic, is three things: the side the filler is on, whether our van can park next to without blocking the road, and if anything has run since you filled up. Then the Ford Focus gets emptied, the filter changed where a usable one exists, your lines cleaned and fresh fuel put through the entire system — as by now the worst of that is in your lines, not that tank.

## AdBlue in the diesel tank instead, around Handsworth Hill?

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

Diluted diesel, and no protection left for the fuel system that depends on it. That's petrol.

AdBlue? Urea dissolved in water. Tip that in with the diesel and you get corrosion instead, plus residue.

Both are ours. There's a separate Handsworth Hill page for AdBlue removal, with the detail on it — including the reasons it frequently turns out to be the worse of the two.

A car you collected two days ago gets driven further before anyone spots anything, which is the hire and courtesy problem in one sentence — and how far it went is what determines the quantity of petrol getting to your injectors. Nothing sloppy about the mistake itself: a modern diesel filler neck accepts the narrower petrol nozzle with practically no resistance, and so strange spots see most of these. Phone us from wherever you are, near Church Of Christ or not, and we'll get to the Dacia Duster.

## What a petrol-in-diesel drain will cost in Handsworth Hill

What changes the price is laid out below, because this job isn't one job and we can't truthfully put a single price on this page.

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

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

- Whether it's unleaded or AdBlue.

- Where is it? And can a technician get to it and work there sensibly?

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

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

It got a couple of streets and stopped. The throttle went dead, the idle turned lumpy, and the diesel Mercedes A-Class is now resting near Darnall Library. That softness is the fuel failing to build pressure fully instead of the engine giving up — and since there's no dashboard light for it, vehicles in that position normally get driven once more before somebody phones. Don't. Turn it off and phone us.

## Petrol in diesel questions from Handsworth Hill drivers

## At a petrol station around Handsworth Hill, can you do a fuel drain there?

Plenty of what our engineers do gets done nowhere else. So yes.

Often, provided the site consents: Shell, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that spot is something we answer there and then.

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

Litres aren't the measure. Ratio is, and a lot more than either, it matters whether anything has been run.

Five litres in a nearly empty tank is a distinct case from five in a full one — but either way, the thing that determines how much work is required is whether that mixture has been sucked through your fuel system.

## I drove the car after putting petrol in my diesel. Now what?

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

Not restarting it is the single most useful thing available to you now. Driving does shift the problem out of the tank and into your pump and injectors, yes, and it stays recoverable far more commonly than motorists fear.

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

A manufacturer's warranty withstands a drain and flush done to a good standard, which is no alteration at all.

A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.

## Adding two-stroke oil, then driving home

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

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

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

You don't need one. The car is drained and flushed wherever it is, with no need to take it to a franchised dealer.

## Is the vehicle still with you?

That engine remains off.

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

Cold and parked, a motor is in the best place available — and motorists fear this a lot more than the recovery rate warrants.

At the kerbside, on the forecourt or at home — mobile fuel draining in Handsworth Hill and across South Yorkshire.
