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

Petrol in Diesel drains and cleans wrong-fuelled cars where they sit, on the forecourt, at the roadside or on a drive, all over Staindrop and the rest of Durham. The first thing to do is not to turn on the engine. While the motor has not run and the petrol is still sitting in your tank, a tank drain is nearly always all it needs, and the following few minutes settle that, not how much got in.

Call us so our team will show you what comes next before you try any more.

## Petrol in a diesel: what to try now

- As you drive, the pump and your injectors suffer. This is why you do not start the car, and why you don't believe it once it has started. The thing about petrol in a diesel specifically — the point people get wrong — is that it pulls away happily for the first mile or two. Diesel in a petrol motor generally cannot run at all, which stops the motorist and stops the damage with them. This one lets you drive on.

- Two tasks, diesel: it combusts, and on the way through it keeps the high-pressure fuel pump and injectors protected. Petrol only handles the one. That is why the ignition remains off also — flick it on and you frequently prime that system, and that is petrol exiting your tank for exactly those components.

- Do not dilute it. Diesel put on top clears nothing, so all you have is more of what was already there, because percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Simply petrol. The grade makes no difference.

- Our team would much rather come to a difficult place than have it started — so if you sensibly can, stay still. Nothing is easier to deal with than a vehicle that has never moved. On the verge on Dovecote Street, that means hazards on and keep it.

- Find out where you are before phoning. A postcode that starts DL2 3, and the name of whatever is next to you. Otherwise our van circles instead of showing up.

- Call 0333 366 0103. Prepare for three questions — what was put in, roughly how many litres, and if the engine has been turned over. The answers shape all that happens next.

The trip back would roughly double it, for no reason at all. One commute has already pushed a real load of petrol-thinned diesel through your high-pressure pump of your Volkswagen Golf. So leave it where it sits. Call us from the platform if that is easier — no one needs you standing over your car outside Bishop Auckland whilst we work, and tonight trumps finding out on Monday.

## Forecourt draining for petrol in a diesel

Most of the job starts at a pump, which means a large portion of it is finished there.

The drain normally happens right there. Still on the forecourt at the nearest petrol station? Given the site's agreement, that is a place we work, and often.

Before the engine has started — the forecourt is the one place it gets caught.

Our engineers can still put it right where it sits, even away from the forecourt. In a car park, on a drive or in a lay-by, the car has been switched on and moved there, and that pulled fuel through your filter then into the high-pressure pump, right from the tank. None of that is a catastrophe, although the flush then has to reach past the tank to your lines and your filter, and the few seconds between checking your receipt and reaching for the key are what decide that.

Away from the pump, the next customer can get past — so yes, let the attendants help you move it. Worth it.

Four car lengths isn't worth a start.

Tell us this much and we can work with it: a diesel Skoda Octavia, a few litres of unleaded in it, two miles or so, turned off at Lidl now. Time elapsed isn't the thing our engineers need. Fuel pulled by the pump is.

## Can our technicians cover your end of Staindrop?

Staindrop is a village, so our team are out to the town and to the areas near it on the usual rounds: Raby, Cleatlam, South Cleatlam, Little Newsham and Wackerfield.

If yours isn't on this list that does not mean we don't come — there are pages for nearly all places across Durham, and the ones mentioned above are simply the nearest neighbours.

On the border, or anywhere the satnav misreads? Call us and enquire rather than assuming.

The patch this page spans is on this map.

Kerbside, forecourt, drive, car park: all of that is ground we work on, and none of it asks your car to travel to us.

Nothing alerts you, as from the driver's seat there's nothing to be warned about. The diesel BMW 3 Series will have felt entirely normal on the way back from Staindrop CofE (Controlled) Primary School, and they all do — which is the snag with petrol in a diesel rather than the reverse. Diesel in a petrol motor usually refuses to run, stopping the driver and stopping the harm with them. Petrol in a diesel starts, ticks over, drives off as though nothing had happened, and all the while your pump keeps working without the lubrication its fuel is meant to supply. Tell us about how far, and how hard. The harder matters more.

## Kerbside breakdowns in Staindrop

Not everyone has the chance to stop anywhere safe.

Set off, then twigged? Ended up on the verge on Office Square, or parked in some lay-by with your hazards going? That's a routine call here. Not an odd one.

Safe there? Remain with it. Not safe? Step out and clear of it.

Don't restart the engine to limp the car somewhere safer — a diesel running on petrol will frequently oblige, and every mile it obliges for is pulling that mix further into your fuel system.

We'll send our van to a difficult location without any bother, and for the car that is much better than driving on.

Leave it overnight. Phone in the morning. Nothing about a diesel Audi A4 parked in the car park at Wheatsheaf Inn degrades as it sits, tank of petrol or not, and the job stays a straightforward one right up until the moment it gets driven home. The query our technicians bring is about that run there: a cold engine over a short run is where petrol burns least well, and whatever fails to burn can work its way past the rings into the oil.

## Petrol in a diesel, and the motor has travelled

Your A1(M) is the road which matters here, and it sits under 10 miles from Staindrop.

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

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

It alters what our engineers bring, and so tell us when you call: on a longer trip — anything close to the under 25 miles to the closest city — assume the mixture has been through the filter, the pump and the injectors.

Diesel has to be viscous enough to seal the precision parts it runs through, and petrol thins it. That is the entire mechanism, and it explains the usual West Middle Lodge Wood call: a diesel Peugeot 3008 that went out there without fuss and came back down on power, rough at idle, possibly smoking a little. A diesel injection system works hydraulically as well as chemically — it needs your fuel to hold pressure, not merely to burn — so when your fuel weakens, pressure that should build then stay built starts leaking past clearances instead, and the motor gets a poorer, later, less even delivery than it was built around. No part of that is the engine failing, which is the part worth hearing: it is your fuel no longer acting like diesel, and it stops when your fuel is corrected.

## A little about Staindrop

Staindrop is a village in County Durham, situated on the riverside in the North East of England, with a population of around 792 people. Staindrop has a mix of housing types, but terraced houses are the most predominant, and it is located near other small settlements such as Raby and Cleatlam. Staindrop sits at an elevation of 112 metres, approximately 16 miles from the city of Durham and 223 miles from London. Staindrop remains a small, quiet community with a strong sense of local identity.

## When our engineers get to you around Staindrop: what follows

- We ask first, quote after. What got in? How much? Has your engine run? Those answers shape what the work really is.

- Away flows the tainted mixture.

- Fuel lines are rinsed through and your filter cleared, leaving nothing in the fuel system that caused any of this.

- Your system gets primed, on new diesel.

- It's fired up with fresh diesel in it, and our engineers confirm that it is running smoothly.

From that point, you're ready to drive away.

There is no need to go to a garage at any stage, because the work is all done where your car is, and when it's spotted soon, lasting damage is very unusual.

## A different job: AdBlue in a diesel tank in Staindrop

AdBlue instead of petrol? Then the first instruction is unchanged — your engine remains off — whereas this problem underneath it's a different one altogether.

The protection a fuel system relies on is taken away by petrol, which dilutes the diesel.

Urea dissolved in water, AdBlue, and in a diesel tank that brings rust and residue.

Usually the more significant of the two, AdBlue — and the full story sits on its own Staindrop page. Both are ours to handle.

## Staindrop costs for a petrol-in-diesel drain

What moves the price is listed below, as the job isn't one job and we cannot truthfully put a single figure on this page.

- This is the key one: whether your motor has been started, or driven.

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

- Which went in: petrol or AdBlue.

- Access: the car's position, and if working on it there's sensible for our van.

Tell us your car, the amount and if it has run, and you'll get a clear answer instead of a range.

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

## Petrol in diesel: everyday questions in Staindrop

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

Yes, and it is where a big part of this work gets done.

Tell us which one you're at when you call and we will tell you whether our engineers can work there. With the station's permission we attend Simpson Fuels and the other forecourts nearby all the time.

## Is there a sensible quantity of petrol in a diesel?

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

Five litres in a nearly empty tank is a distinct matter from five in a full one — but either way, the thing that decides how much work is required is whether that mix has been drawn through the fuel system.

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

Stop sensibly. Off. Nothing after that.

Driving is what moves the issue from that tank into the pump and injectors — but it's recoverable much more often than drivers expect, and the single most valuable thing you can do now isn't restart the vehicle.

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

A drain then flush carried out properly is not a change and doesn't void a manufacturer's warranty.

Another good reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a disagreement with one.

## Can I just add two-stroke oil and drive home?

Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol thinned. No.

Later on? Still petrol in the tank, and a pump that has to put up with the stuff.

## A main dealer for petrol in a diesel — necessary?

There is no need to take it to a main dealer, since we drain and flush the vehicle wherever it is.

## You, and your car, still together?

Shut off is how it remains.

If you have already driven it, pull in somewhere safe, switch it off then leave it off.

Cold, still, going nowhere: that is the best position to be in. Motorists fear this a lot more than they need to.

On-site fuel draining in Staindrop and throughout Durham — at the roadside, on the forecourt or at home.
