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

Petrol in Diesel drains and flushes misfuelled vehicles where they stand, on the forecourt, at the roadside or on a drive, across Goudhurst and the remainder of Kent. The first thing to do is not to fire up the engine. When your engine has not turned over and the petrol is still sitting in your tank, a tank drain is nearly always all it takes, and the coming few minutes settle that, not how much was put in.

Ring us before everything else starts, and you'll learn what happens after that.

## What to try now about petrol in a diesel

- While you drive, the pump and your injectors wear down. That is why you do not start it, and why you never depend on it once it has started. The thing about petrol in a diesel specifically — the bit motorists get wrong — is that it drives off happily for the first mile or two. Diesel in a petrol motor generally can't run at all, which stops the motorist and stops the damage with them. This one lets you carry on.

- Turning the ignition on usually primes the system, and priming is what pulls petrol out of that tank and into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it combusts. Petrol handles the burning and none of the protecting. Leave the car's ignition off.

- Don't tip diesel on top to weaken it. A diesel fuel system will not cope with petrol by percentage in the way that guidance implies, and topping up gets rid of nothing — it merely leaves you a larger tank of the same mix. The grade makes no difference either: super unleaded is simply petrol.

- We'd much rather travel to an awkward place than have it started — so if you reasonably can, stay still. Nothing is quicker to sort than a car that hasn't shifted. On the verge on North Road, that means hazards on and keep the car.

- Keep your location ready before you phone. A postcode beginning TN17 1 and whatever is next to you with a label on it is the difference between our van showing up and the van circling.

- Phone 0333 366 0103. Let us know what went in, roughly how much, and whether the engine has fired. These three answers shape the whole call-out.

## Clearing petrol from the diesel at the forecourt

The job kicks off at the pump, typically. Often enough the work wraps up there too.

Our technicians work on station forecourts regularly, with the station's agreement, so if you're still at Weald Service station that's normally where the drain takes place.

A forecourt is the only location it gets caught before the engine has fired.

Anywhere else — a car park, a drive, a lay-by — the car was started and driven to get there, which means fuel was sucked from that tank, through the fuel filter then into your high-pressure pump. That is not a calamity, and our engineers can still sort it out where it is. It does mean the fuel lines and the filter need cleaning as well as your tank, and that's decided by the few seconds between seeing the till receipt and going for the key.

The attendants will usually offer to wheel the car out from the petrol pump so the next driver can get past. That's worth doing.

Rolling it four spaces does not merit cranking the engine.

Petrol in your Volkswagen Passat, and it takes diesel? Shopping in your boot, you at Heath Stores, somewhere in Goudhurst? Then phone, and leave your engine out of that — not even to get out of that bay. Somebody heads your way. Tank cleared, fuel lines purged, new diesel in, and home you go. Easy throttle over a mile uses hardly anything, so these are usually the simple jobs.

## Goudhurst plus the places next to it

Brandfold, Smallbridge, Broad Ford, Iden Green, Capel Cross — each of them on our trips that take us out to Goudhurst as well, a rural village.

Not on the list? It means nothing. The places above are only the closest few, and most locations around Kent have a page of their own somewhere on this site.

Close to the boundary, or somewhere the satnav can't find? Phone to enquire rather than assuming.

That map shows the patch the page includes.

Kerbside, forecourt, drive, car park: the lot is territory our engineers cover, and none of it asks the car to move to us.

Put diesel in a petrol car and generally it won't run, so the motorist stops there and the damage stops with them. Flip it — petrol into a diesel — and the thing fires up, ticks over and drives off as though nothing had happened, while the high-pressure pump works without the protection your fuel is meant to be supplying. That is the snag, and it is why your diesel Skoda Octavia will have felt entirely ordinary coming back from Goudhurst and Kilndown Church of England Primary School. They all do. From the driver's seat there's nothing to alert you about, and so nothing alerts you. Ring us with roughly how far you went, and how hard; the second one matters more than the first.

## Roadside breakdowns in Goudhurst

Not everyone has a suitable spot to stop.

If you realised after setting off and ended up by the verge on High Street, or in a lay-by somewhere with your hazards going, that's a routine call for us and not an unusual one.

Stay with the car while it is safe to wait inside, but clear of the car when it's not.

Every mile a diesel obliges you for on petrol draws that mixture further into your fuel system — and oblige it often will, which is why the engine does not get restarted to limp somewhere safer.

However difficult the place, it is no trouble for us to come to it, and that is much better for the car than pressing on.

Park it overnight. Phone next morning. Nothing about a diesel Nissan Qashqai parked in the car park by The Vine degrades as it waits, tank of petrol or not, and the job remains a straightforward one right up till the moment it gets driven home. The query our technicians bring is about the run there: a cold motor over a short hop is where petrol ignites least well, and whatever fails to burn can work its way past the piston rings into the engine oil.

## Already driven it? Petrol in a diesel over some miles

Here is where the local M20 counts, under 15 miles out of Goudhurst.

Lost power, an uneven idle, some smoke: those are the signs when they appear, instead of a clean stop — and a wrongly fuelled diesel will frequently take you onto it and some distance along before anything seems wrong at all.

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

Long run? Anything near the under 50 miles to the closest city and you should assume the lot — filter, pump, injectors, all of it arrived at by the contamination. Say that on the phone, as it affects what goes in our van.

## Goudhurst itself

Goudhurst is a rural village in Kent, situated inland at an elevation of around 115 metres, and is located approximately 37 miles from London. Goudhurst has a mix of housing types, but semi-detached homes are predominant, and the village is surrounded by smaller settlements like Brandfold and Smallbridge. Goudhurst remains a small, quiet community with a population of around 1104 residents, and is near the larger city of Canterbury, which is about 29 miles away.

## Our visit in Goudhurst, step by step

- We ask first, quote after. What was put in? How much? Has the motor run? Those responses alter what the work actually is.

- The tank is drained of everything.

- Lines rinsed, filter cleared. Whatever remains later is not the thing that started the issue.

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

- We turn it on and check it runs properly on fresh diesel.

At that point it is ready to pull away.

Our technicians do everything wherever the vehicle has come to a stop, which means it never needs to be taken to a garage, and if it has been noticed soon, it's very unusual for there to be long-term damage.

Pulled off the forecourt, read the receipt, and parked your diesel Mercedes C-Class up by Goudhurst Parish Hall a couple of hundred yards later? That is about as well as this goes once your engine has turned. Call us and leave it off. The short distance truly assists, but it was still a start and a drive, and so weakened fuel has got to the fuel filter and the pump — which is why our engineers clean the lines rather than only emptying the tank.

## AdBlue in the diesel tank by mistake, around Goudhurst?

Do not fire it up: that first step holds whether what got in was AdBlue or petrol. What differs is the fault itself.

Diluted diesel, and no lubrication left for the fuel system that relies on it. That is petrol.

AdBlue? Urea dissolved in water. Pour that in with the diesel and you get corrosion instead, plus build-up.

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

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

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

- This is the main one: whether your engine has been started, or driven.

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

- The kind of liquid in the tank, petrol or AdBlue.

- Access: the vehicle's position, and if working on it there is safe for our van.

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

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

Put right and starting are not the same thing, and the difference is the system: our technicians flush it, and take your filter off where there's a working one. Compare that with the certain advice you will get — drain the car, refill with clean diesel. Only half right. Do exactly that to a diesel Audi A3 by Moat and it will start, which is exactly why the tip sounds plausible. Then the engine pulls the petrol left behind in the fuel filter, and in the feed lines, straight back through your pump, as draining a tank does nothing whatever about fuel that has already left it. Call us instead.

## Goudhurst drivers ask us these about petrol in diesel

## I'm on a forecourt around Goudhurst. Can you drain the vehicle on the spot?

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

Tell us which one you're at when you call and we will tell you whether we can work there. With the station's consent our technicians attend BP and the other forecourts locally routinely.

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

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

A nearly empty tank with five litres in it, against a full one with the same five: separate scenarios, certainly. Either way, the work required comes down to one thing, which is whether the system has had that mixture drawn through it.

## Already driven it with petrol in your diesel? What now?

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

Driving shifts the trouble along — out of your tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one truly valuable thing left to you isn't restarting it.

## Will a fuel drain void my warranty?

A manufacturer's warranty outlasts a drain then flush done to a proper standard, which is no alteration at all.

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

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

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

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

## Main dealers and petrol in a diesel

Not at all. We drain and clean your car wherever it is, so there's no need to take it to a franchised dealer.

## Still with your car?

Leave it switched off.

Driven it already? Then somewhere sensible, stop, turn off, and no restarting the car after that.

This is recoverable from far more regularly than people assume, and a still, cold vehicle is the best place to be in.

Mobile fuel draining around Goudhurst and throughout Kent — at the kerbside, on the forecourt or at home.
