# Lower Willingdon: Put Petrol in a Diesel Car?

If you have not started the engine as yet, do not. A fuel drain and nothing more is almost always what a vehicle requires while the petrol is still in your tank and your engine has not run, which is why it's the following few minutes that count, not how much was put in. Petrol in Diesel goes to the vehicle wherever it has ended up in Lower Willingdon or the remainder of East Sussex, on the forecourt, at the roadside or on a driveway, and drains and cleans it there.

Our technicians can tell you what your next step will be. Call us — this happens before everything else.

## Your first five steps: petrol in a diesel

- While you drive, the pump and the injectors wear down. This is why you don't crank it, and why you do not believe it once it has started. The trick about petrol in a diesel specifically — the point most people get wrong — is that it drives away happily for the first mile or two. Diesel in a petrol engine generally will not run at all, which stops the driver and stops the wear with them. This one lets you keep going.

- Leave the car's ignition be too. Diesel has two tasks: it combusts, and before it combusts it lubricates that injection pump and those injectors. Petrol handles the first but not the second. Flicking the car's ignition on is commonly sufficient to prime the system, which pulls this petrol out of the tank then into exactly those parts.

- Do not add diesel on top to weaken it. A diesel fuel system will not handle petrol by percentage the way that advice assumes, and topping up takes out nothing — it simply gives you a larger tank of the same blend. The octane makes no difference either: super unleaded is just petrol.

- Remain where you are if you sensibly can. A motor that has never moved is the simplest one to handle, and we would rather travel to an awkward place than have it started. If you're parked on the verge on Coppice Avenue, put those hazards on and leave it there.

- Get your location ready before you phone. A postcode that starts BN20 9 and whatever is next to you with a label on it is the difference between our van arriving and a van circling.

- Three replies decide the whole job: the liquid you poured in, the rough amount of it, plus if it has been going since. Our line is 0333 366 0103.

Quarter past eight, a rushed fill-up on the trip in, and it dawns on you somewhere around eleven — by that point your diesel Peugeot 308 has been standing outside Polegate for three hours. Ring us and leave it just where it is. The run in is the part that is key here, as diesel does two tasks on its way through the engine: it ignites, and before it combusts it protects the injection pump and its injectors. Petrol manages the first and not the second. So those few miles were travelled with your pump labouring on a liquid that had shed much of the protection it is built around — which is why the question our engineers ask is how many miles you travelled, not how long the vehicle has been parked.

## Removing petrol from your diesel at a forecourt

A fair share of the job ends up finished at a forecourt, because that's where it often begins.

We work on petrol station forecourts all the time, with the owner's agreement, so if you're still at BP that's typically where the drain gets done.

Before the motor has run — a forecourt is the one spot this ends up stopped.

We can still put it right where it is, even away from the pumps. In a car park, on a private drive or in a lay-by, the car has been fired up and moved there, and that drew fuel through your filter then into your high-pressure pump, all the way from the tank. None of that is a catastrophe, but the flush then has to go past that tank to the fuel lines and your filter, and the few seconds between reading your receipt and going for the keys are what decide that.

The attendants will normally happily push the vehicle away from the petrol pump so the next driver can get by. That's worth doing.

Moving the car four lengths doesn't merit starting the motor.

Diesel Nissan Qashqai. A couple of litres of unleaded. Done a couple of miles. Turned off now, at Lidl. That's the phone call our engineers hope for, because the real question beneath it's about quantity through your pump not hours on the clock.

## Lower Willingdon plus the villages near it

These same runs get us to Foulride Green, Willingdon, Wannock, Polegate and Filching as well as Lower Willingdon, which is a rural village.

Our engineers do come. Those names above are just the closest neighbours, and a page exists for the majority of locations in East Sussex, so an absence from the list is not an absence from our coverage.

Ring us to check instead of assuming — borders above all, and wherever the satnav can get wrong.

Use the map for the ground covered here.

All of that is territory our technicians cover: a kerbside, a forecourt, a drive, a car park. You never move your car anywhere.

Each restart primes your lines and drags more petrol through your filter then into the pump. So a misfilled diesel Ford Kuga on the zig-zags by Willingdon Primary School is a nuisance, whereas the same vehicle fired up three more times to be polite is a fuel system rather than a tank. Somebody will urge you to shift the vehicle out of the gateway and deal with it later. Don't. Stay put, let people grumble, then phone us.

## Lower Willingdon: stranded wherever you stopped

Not everyone finds a safe spot to stop.

Set off, then realised? Landed along the verge on The Triangle, or parked in some lay-by with the hazard lights on? That's a routine call here. Not an unusual one.

Whether you sit beside your car or keep away from it hangs on if staying nearby seems sensible.

Don't start it up to get to a safer location. It'll go — a diesel on petrol normally obliges — and each mile of obliging drags the blend deeper into the system.

However tricky the location, it's no bother for us to get to it, and that is far better for your car than pressing on.

## Petrol in a diesel, but your car has travelled

The local M23 is the one which matters now, and runs under 50 miles from Lower Willingdon.

A drop in power, an uneven idle, some smoke: those are the symptoms when they come, rather than a neat stop — and a wrongly fuelled diesel will often take you onto it and some way along before anything seems wrong at all.

Take the next exit that is sensible, pull up there, and don't start the vehicle to reposition.

Long trip? Anything near the under 25 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it got to by the mixture. Say that on the phone, as it affects what goes in the van.

Sitting still, it gets no worse. The pump is not turning, so whatever happened on the way to Huggets Lane Recreation ground in that diesel Citroen C3 is finished happening. Time is yours. Just do not take it home on the motor to find more of it.

## About Lower Willingdon

Lower Willingdon is a village in East Sussex, situated inland at a low elevation of around 14 metres. Lower Willingdon lies near the towns of Willingdon and Wannock, and is approximately 17 miles from the city of Brighton and Hove. Lower Willingdon has a population of around 2343 people, predominantly living in semi-detached housing. Lower Willingdon is also within commuting distance of London, being around 51 miles from the capital.

## What our technicians do when we get to you around Lower Willingdon

- The responses change the work, which is why we ask before giving a price: what was put in, how much of that, and if your motor has run.

- We clear that tank of the polluted mixture.

- Our technicians flush the lines and clean the fuel filter, so what is left in the fuel system is not what created the trouble.

- We put new diesel in and bleed your system.

- Once it's fired up, we confirm it runs smoothly on fresh diesel.

That has the car ready to pull away.

All of it is done where the vehicle is, so it never has to go to a workshop, and when it has been noticed early, permanent damage is very rare.

## AdBlue in a diesel tank in Lower Willingdon is a different job

AdBlue instead of petrol? Then the opening rule is unchanged — the engine remains off — whereas the problem beneath it is a separate one altogether.

Petrol dilutes your diesel and removes the lubrication your fuel system relies on.

Rust and residue are what a diesel tank ends up with instead, because AdBlue is urea dissolved in water.

Often the more serious of the two, AdBlue — and the detail sits on its own Lower Willingdon page. Both are ours to handle.

## How much is a petrol-in-diesel drain around Lower Willingdon?

One price wouldn't be fair here, since this isn't one job. These are the things that change it:

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

- How much of the wrong fuel got in, against how much the tank can hold.

- Whether it's unleaded or AdBlue.

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

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

Not pressing, with the car at home and going nowhere? Then  does the job.

Somebody sure of themselves will tell you to drain the car then put new diesel in. Half true, that. Try it on a diesel Renault Captur near Willingdon Library and your engine will start — which is exactly why it sounds like sense. Here is the problem: there's petrol left in the fuel filter and the feed lines, and the first thing your engine does is draw it back through your pump a second time. Emptying a tank achieves nothing about fuel that already left that tank. Phone us. The circuit gets purged, your filter comes off where there's one worth removing, and that's what separates a fixed motor from one that merely starts.

## Petrol in diesel questions from Lower Willingdon motorists

## Can you do a fuel drain at a petrol station around Lower Willingdon?

Yes — forecourts are where a big part of this happens.

Tell us which one you're at when you phone and we will tell you whether we can work there. With the owner's agreement our engineers attend Esso and the other forecourts nearby regularly.

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

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

What decides how much work is needed is if that mixture has been sucked through your fuel system — because though five litres in an almost empty tank is a separate matter from five in a full one, either way that's the question.

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

Pull in somewhere safe, switch off, and keep the vehicle off.

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

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

A manufacturer's warranty withstands a drain then flush done to a correct standard, which is no change at all.

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

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

No. Two-stroke oil is an old fix for a separate issue and it doesn't replace what petrol has thinned.

The pump still has to put up with it, as that tank still has petrol in it later.

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

Not at all. We drain and flush your car wherever it is, so there is no need to take it to a main dealer.

## Is your vehicle still with you?

The engine remains off.

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

A stationary, cold car is the best position to be in, and this is recoverable from much more often than people assume.

Call-out fuel draining around Lower Willingdon and across East Sussex — at the kerbside, on the forecourt or at home.
