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

Do not fire up your engine. If the petrol is still sitting in the tank and the motor has not yet run, a tank drain is nearly always all it requires — and that's determined in the next few minutes, not by how much went in. Petrol in Diesel drains and cleans misfuelled cars where they sit, across Broke Hall and the rest of Suffolk, on the forecourt, by the roadside or on a drive.

Our technicians can tell you what your next move is. Ring us — it goes before all else.

## Petrol in a diesel: what to do first

- Do not fire it up. Turned on all the same? Then do not depend on it. Diesel in a petrol vehicle typically will not run, and so the person stops and the wear stops with them. Petrol in a diesel? It starts. It ticks over. It drives off fine, for a couple of miles. Drivers get that muddled. It's not all right — that fuel system is wearing every mile you cover.

- Turning your ignition on frequently primes that system, and priming is what pulls petrol out of your tank and into the pump and injectors. Those are the components diesel keeps protected on its way through, before it ignites. Petrol does the burning and none of the protecting. Leave the ignition off.

- That guidance supposes a diesel fuel system copes with petrol by percentage. It won't. Tip diesel on top and nothing at all is taken out; what you have is a larger tank of the same mix. And no, the type makes no difference — super unleaded is just petrol.

- We'd sooner travel to a tricky spot than have it started — so if you safely can, stay still. Nothing is quicker to sort out than a motor that hasn't shifted. On the verge on Bucklesham Road, that means hazards on then keep the car.

- Our van arriving rather than circling hinges on two things: a postcode that starts IP3 8, and whatever is nearest to you with a sign on it. Get both ready before you ring.

- What got in, about how much, plus if the car has fired — those three details decide the full job. Phone 0333 366 0103 and tell us.

## Draining petrol from your diesel on a forecourt

Much of this work begins at a forecourt, meaning a fair share of it is completed on site.

The drain generally takes place there and then. Still on the forecourt at Sainsbury's? Given the site's permission, that's somewhere we work, and regularly.

The forecourt is the one spot it gets spotted before the engine has started.

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

The attendants will normally offer to roll the car away from the petrol pump so the next customer can get through. That is worth doing.

Cranking it to roll four vehicle lengths isn't.

## Service around Broke Hall

Being a residential suburb, Broke Hall has a regular call, whilst the areas nearby come along on the same run: Warren Heath and Racecourse, Priory Heath and Gainsborough, Rose Hill.

If yours isn't on that list it does not mean we don't come — there are dedicated pages for nearly all locations in Suffolk, and the ones listed above are merely the nearest neighbours.

Near the boundary, or anywhere the satnav gets wrong? Contact us to ask rather than guessing.

The area the page spans sits on the map.

The vehicle never needs to move to us. Our technicians work throughout the lot — kerbside, forecourts, driveways, car parks.

Twenty to nine outside Broke Hall Community Primary School, running late, and the receipt in your hand reads unleaded. Hazards on, engine off, phone us. Three miles in your Peugeot 308 sounds like nothing, but a diesel pump delivers fuel on demand — and a hurried morning run needs plenty.

## Stranded by the roadside anywhere around Broke Hall?

A chance to stop somewhere safe does not come to everyone.

If you realised after setting off and landed by the verge beside Warren Heath Avenue, or in a lay-by somewhere with your hazards on, that is a normal call for us instead of an odd one.

Out of the vehicle when it is not safe to wait in it, beside it when it is.

Never start up the engine to limp the vehicle somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is pulling the mixture further into your fuel system.

However awkward the spot, it is no problem for us to come to it, and that is a lot better for your car than pressing on.

A diesel Ford Focus in the car park at The Golden Hind carrying a tank of petrol in it is an easy job, right up till someone drives it home. Leave it there overnight then phone us in the morning. Nothing worsens while it waits. What we'll want to know is if that drive there was short and chilly, as that is where petrol is slowest to burn fully — and whatever does not burn can work past the piston rings and into the sump.

## Petrol in a diesel, but the motor has rolled

under 50 miles out of Broke Hall, the local M11 is what counts now.

It will frequently take you onto it, and some way along, before you feel a thing. Then it's smoke, a lumpy idle and power ebbing away — not a clean stop. Wrongly fuelled diesels seldom give you one of those.

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

It alters what our engineers bring, so tell us when you call: on a longer drive — anything approaching the under 25 miles to the closest city — take it the mixture has been through the filter, your pump and the fuel injectors.

None of that is the engine failing. That's the part worth hearing, and it's why the ordinary Cobham Road Recreation Ground call ends better than it sounds: a diesel Mercedes C-Class drives out there without fuss, comes back with the power gone, your idle lumpy and possibly a little smoke, and the cause is the fuel no longer behaving like diesel. Diesel has to be thick enough to seal the tightly fitted components it flows through; petrol dilutes it; and a diesel injection system is hydraulic as much as chemical, needing your fuel to hold pressure instead of only to burn. So pressure that should build then stay built bleeds past gaps, delivery arrives poorer and later and less even than built, and all of that stops once your fuel is put right.

## A little about Broke Hall

Broke Hall is a suburban area in Suffolk, situated near the coast and approximately 32 metres above sea level. Broke Hall is located near several other local places, including Warren Heath, Racecourse, and Priory Heath. Broke Hall has a population of around 4233 people and is characterised by predominantly semi-detached housing. Broke Hall is also within commuting distance of London, being around 67.8 miles away, and is closer to the city of Colchester, which is 16.6 miles away.

## Our job in Broke Hall, step by step

- The replies alter the work, which is why our technicians ask before quoting: what got in, how much of it, and whether your engine has run.

- The tank is drained completely.

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

- We pour new diesel in and bleed your system.

- When it's fired up, we check it runs properly on fresh diesel.

That leaves it ready to drive away.

There's no need for a workshop at any stage, as the work is all done where your car is, and when it is spotted quickly, long-term damage is very rare.

Emptying the BMW X1, changing your filter where there is a serviceable one, purging the fuel lines, putting clean fuel through the full system: that's the job, and it's shaped by the worst of that resting in your lines instead of in the tank by this point. Three things help when you call from close to St Augustines Church — which side the filler is on, whether a van can park next to without blocking the road, and if the engine has run since you filled up. On-street is the commonest spot we work, and so the spot itself is rarely the trouble. A tight parking spot beats a vehicle driven somewhere more handy.

## AdBlue in a diesel tank around Broke Hall is a different job

AdBlue instead of petrol? Then the opening instruction is unchanged — the motor remains off — whereas the problem under it is a separate one altogether.

Petrol does two things to diesel: weakens it, and removes the protection the fuel system relies on.

AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and residue instead.

Our engineers cover both, and AdBlue removal around Broke Hall has its own page with the details — including why it is frequently the more serious of the two.

Petrol in a diesel does its harm as a proportion, which is the reason our engineers ask at all: the same few litres sitting in a nearly empty tank make a far stronger blend than they would in a full one. And petrol is rated on how well it resists igniting under pressure — the opposite of what a diesel needs — so a stronger mix knocks more, smokes more, goes flatter. None of which means you need an answer ready. Nearly nobody knows how full your tank was in a car collected two days ago, and we work that out on site. Do phone the hire or company firm first, though: some agreements want them to authorise the work, and that is far quicker settled before than after. Then phone us about the Citroen C3 by St Augustine's Church Hall.

## Paying for a petrol-in-diesel drain around Broke Hall

One price wouldn't be honest here, since this is not one job. These are the things that shift it:

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

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

- Whether it is petrol or AdBlue.

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

Tell us the vehicle, the quantity and if it has run, and you'll get a firm answer instead of a range.

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

## Petrol in diesel questions from Broke Hall drivers

## I'm on a forecourt in Broke Hall. Can you drain it here?

Plenty of what we do takes place nowhere else. So yes.

Tell us which one you're at when you phone and we'll tell you whether our engineers can work there. With the owner's consent our technicians work at East of England Co-op and the other forecourts locally regularly.

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

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

Five litres in an almost empty tank is a different case from five in a full one — but either way, the thing that settles how much work is needed is whether that mix has been drawn through your fuel system.

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

Switch off somewhere safe, and keep it that way after you stop.

Driving moves the problem along — out of your tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting it.

## 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 modification at all.

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

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

Two-stroke oil solves a distinct issue, and an old one at that. Nothing it does puts back what petrol diluted. No.

Your pump still has to live with it, as that tank still has petrol in it later on.

## Main dealers and petrol in a diesel

There's no need to bring it to a franchised dealer, because our engineers drain and clean the vehicle wherever it is.

## You, and the car, still together?

Don't switch the car back on.

If you have already driven the car, pull in somewhere sensible, switch it off and leave it off.

This is recoverable from much more commonly than drivers assume, and a stationary, cold vehicle is the best place to be in.
