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

Don't start the motor. While the fuel is still in the tank and the motor has not yet run, a tank drain is almost always all it requires — and that's settled in the next few minutes, not by how much went in. Petrol in Diesel drains and cleans wrong-fuelled cars where they are, throughout Havannah and the rest of Cheshire, on the forecourt, by the roadside or on a driveway.

Call us so we will explain what happens after that before you try any more.

## Petrol in a diesel: what to try first

- Never crank it. Turned on anyway? Then don't depend on it. Diesel in a petrol car typically will not run, so the driver stops and the harm halts with them. Petrol in a diesel? It starts. It idles. It pulls away happily, for a couple of miles. Most people get that muddled. It's not all right — your fuel system is grinding every mile you drive.

- Two jobs, diesel: it combusts, and on the way through it keeps your high-pressure fuel pump and injectors greased. Petrol only handles the one. Which is why your ignition remains off also — turn it on and you commonly prime your system, and that's petrol exiting that tank for just those components.

- That advice presumes a diesel fuel system handles petrol by percentage. It won't. Put diesel on top and nothing at all is cleared; what you have is a larger tank of the same mix. And no, the grade makes no difference — super unleaded is just petrol.

- A vehicle that has not shifted is the simplest one to sort out, so wait where you are if you reasonably can. Parked on the verge on Gordale Close? Hazards on, and keep it there. An awkward location works for us better than a started diesel.

- Keep your location ready before you call. A postcode beginning CW12 2 and whatever is nearest to you with a name on it is the difference between our van turning up and our van circling.

- Three details determine the full job: the fuel you poured in, the rough measure involved, plus if anything has been running since. Our line is 0333 366 0103.

Quarter past eight, a fast top-up on the trip in, and the penny drops around eleven — by that point the diesel Volkswagen Golf has been standing at Congleton for three hours. Phone us and leave it exactly where it is. The journey in is the part that is key most, as diesel performs two tasks on its way through a motor: it ignites, and before it burns it protects the high-pressure pump and the injectors. Petrol handles the first and not the second. So those couple of miles were driven with the pump running on a liquid that had shed most 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 sitting.

## At the forecourt: draining petrol from a diesel

The work starts at a forecourt, typically. Often enough the work wraps up at one too.

We operate on station forecourts all the time, with the owner's permission, so if you are still at the nearest petrol station that is typically where the drain takes place.

At a forecourt, this is spotted with the engine never fired, and nowhere else does that.

Our engineers can still deal with it where it stands, even away from the pumps. In a car park, on a drive or in a lay-by, the vehicle has been fired up and moved there, and that sucked fuel through the fuel filter then into your high-pressure pump, all the way from the tank. None of that is a disaster, though the flush then has to reach past your tank to your lines and the fuel filter, and the few seconds between reading the receipt and going for the keys are what settle that.

The attendants will generally happily wheel the vehicle out from the petrol pump so the next motorist can get past. That's worth doing.

Four car lengths isn't worth a start.

If you have put petrol in your diesel Renault Megane around Havannah and you're now stuck at The Co-operative Food with a boot loaded with shopping, phone us. Do not fire it up a second time to exit the spot. We will come out to you, drain your tank, purge the fuel lines and put fresh diesel in so you can get home. A mile or so at easy throttle uses very little of it, which is why these are usually the simple jobs.

## Havannah and the places near it

These same trips get us to Buglawton, Bath Vale, Eaton, Lower Heath and Key Green as well as Havannah, which is a small village.

If yours is not on that list that does not mean we don't come — there are separate pages for the majority of towns across Cheshire, and the ones listed above are just the closest neighbours.

Near a border, or anywhere your phone misreads? Contact us to ask rather than presuming.

See the map for the area covered on this page.

We work at the roadside, on forecourts, on driveways and in car parks throughout all of it, and the vehicle never needs to come to us.

Twenty to nine at the gates of Havannah Primary School, running late, and the till receipt in your hand says unleaded. Hazards on, ignition off, ring us. Three miles in your BMW 3 Series sounds like nothing, but a diesel pump supplies fuel to demand — while a hurried morning drive asks for plenty.

## Roadside stops across Havannah

Not everyone gets a sensible spot to pull in.

Hazards going in a lay-by somewhere, or stopped on the verge of Swaledale Avenue as you worked it out after setting off — our engineers take that call often enough that it's the ordinary kind.

Whether you wait beside the car or keep away from it rests on whether staying there looks sensible.

Never start up your motor to limp the vehicle somewhere safer — a diesel running on petrol will frequently oblige, and every mile it obliges for is drawing the mixture further into the system.

Pressing on does your car far more harm than our van driving out to a difficult place, and that is no trouble for us.

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

Here is where the M6 comes into it — under 10 miles away from Havannah.

Some distance along, and onto it in the first place: a misfuelled diesel will usually do both before anything feels wrong. What you get then is rarely a clean stop. Power falls away, your idle goes lumpy, and there may be some smoke.

Take the next exit that's safe, pull up there, and never restart it to reposition.

Suppose the worst of it on a long drive. Anything close to the under 15 miles to the nearest city, and the mixture has been through the fuel filter, through the pump, through the fuel injectors. Mention it when you phone. What our engineers bring differs.

## All about Havannah

Havannah is a locality in Cheshire, situated on the riverside with a mix of detached housing and open spaces. Havannah has a population of around 877 people and is located near other small places like Buglawton and Eaton. Havannah sits at an elevation of 124 metres, close to the city of Stoke-on-Trent, and is about 144.5 miles from London. Havannah is part of the wider North West region of England, with its own distinct character and setting.

## What we do when we arrive with you around Havannah

- Three things get checked before any price — the fuel that went in, the amount, and whether anything has been run since. Each answer alters the work.

- The tainted fuel comes from the tank.

- What is left in your system should not be what started the trouble, and so the lines get flushed and the filter cleared.

- Priming follows, once fresh diesel is in.

- We start the engine and make sure it runs properly on new diesel.

The car is then ready for you to drive away.

There's no need for a workshop at any point, since the work is all done where the vehicle is, and when it's spotted quickly, permanent damage is very unusual.

Clearing the Dacia Duster, changing the fuel filter where there's a usable one, cleaning the fuel lines, putting clean fuel through the entire circuit: that is this job, and it's shaped by the worst of that sitting in the fuel lines instead of in that tank by this point. Three things help when you phone from close to 1st Buglawton Scout Group — which side the filler is on, whether a technician can stand next to without blocking the road, and whether the motor has run since you filled up. On-street is the usual spot our engineers work, and so the location itself is rarely the issue. A tight parking bay trumps a vehicle driven somewhere more convenient.

## A different matter: AdBlue in a diesel tank around Havannah

AdBlue instead of petrol? Then the opening rule is unchanged — the engine stays off — while the problem under it's a separate one altogether.

The protection a fuel system depends on gets taken away by petrol, which weakens the diesel.

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

Our engineers handle both, and AdBlue removal around Havannah has its own page with the full story — including why it's frequently the more significant of the two.

Switch off where you have stopped, and never start it to find somewhere better — near Parish Church of St John the Evangelist or anywhere at all. Rattling, a lumpy idle, white smoke and a dead throttle are a misfilled diesel Kia Sportage telling you what's wrong.

## Havannah costs for a petrol-in-diesel fuel drain

One price would not be honest here, as this isn't one job. These are the things that move it:

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

- How much of the wrong fuel was put in, weighed against how much the tank takes.

- Which got in: petrol or AdBlue.

- Whether a van can sensibly get to the vehicle and work on it, which hinges on where the car is.

A clear answer rather than a range is what you get for telling us three things: the vehicle, the quantity, and if it has run.

If it's not pressing — your car is at home and going nowhere —  works too.

## Havannah drivers ask us these about petrol in diesel

## At a petrol station in Havannah, can you do a fuel drain there?

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

Tell us which one you're at when you phone and we will tell you if our engineers can work there. With the owner's agreement our engineers attend Cheshire Town & Country Fuels and the other forecourts nearby all the time.

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

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

Five litres in a nearly empty tank is a separate matter from five in a full one — but either way, the thing that determines how much work is needed is if that blend has been pulled through the system.

## Petrol in my diesel, and I have driven it

Turn off somewhere sensible, and keep it that way after you stop.

Not restarting it is the single most helpful thing available to you now. Driving does move the issue out of that tank and into your pump and injectors, yes, and it stays salvageable a lot more regularly than drivers fear.

## Fuel drains and manufacturer warranties

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

What is likelier to start an argument is a diesel that has been run on petrol. One more reason for the motor to stay off.

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

No. It belongs to a separate fault from a different era, and petrol has thinned something no oil of that kind replaces.

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

## Main dealers and petrol in a diesel

There's no need to bring it to a dealership, since we drain and clean your car wherever it is.

## Still with the vehicle?

Don't switch it on again.

If you have already driven the vehicle, stop somewhere sensible, turn it off and keep it off.

A parked, cold car is the best place to be in, and this is recoverable from much more frequently than people assume.

Across Cheshire and around Havannah: call-out fuel draining, at home or on the forecourt or at the roadside.
