Petrol in a Diesel Car in Frimley

With your tank still carrying the fuel and the engine not yet turned over, almost every job requires only a drain, so keep the motor off. That result is decided in the minutes immediately after filling up, rather than by the amount that got in. All over Frimley and the rest of Surrey, Petrol in Diesel drains your car and cleans it where it sits, whether by a roadside, on a private drive or at a forecourt. Phone and then our team shall tell you what follows next before you attempt anything else.

Petrol in a diesel: what to do first

  • Give a petrol motor diesel and it will normally not run at all, and so the person stops there and so does the wear. Feed a diesel petrol and the car starts, it ticks over, it moves off — fine enough for a few miles. Drivers have that reversed, which is the part they get wrong about petrol in a diesel especially. So never crank it. And having started, never depend on it: your fuel system is wearing down while you drive.
  • Switching your ignition on often primes the system, and priming is what draws petrol out of the tank and into the pump and injectors. Those are the components diesel keeps greased on its way through, before it combusts. Petrol does the burning and none of the lubricating. Leave the ignition be.
  • Do not dilute it. Diesel tipped on top takes out nothing, and so all you have is more of what was already there, since percentage is not how a diesel fuel system accepts petrol. Super unleaded? Still petrol. The type makes no difference.
  • Stay put if it's safe to. Hazards on, engine off, leave the vehicle. Wherever you have stopped — the verge on Frimley Green Road, anywhere — a tricky location for us beats a started motor, and nothing is easier for us to handle than a car that never shifted.
  • Our van showing up instead of circling turns on two things: a postcode beginning GU16 8, and whatever is nearest to you with a label on it. Get both prepared before you phone.
  • Dial 0333 366 0103. Let us know what went in, approximately how much, plus if the motor has fired. These three details settle the whole job.

Quarter past eight, a fast top-up on the drive in, and it dawns on you at about eleven — by that point the diesel Volkswagen Golf has been sitting at the nearest station for three hours. Call us and keep the vehicle right where it sits. The run in is the part that counts now, since diesel has two roles on its way through an engine: it combusts, and before it burns it greases that high-pressure pump and those injectors. Petrol manages the first and not the second. So those couple of miles were driven with your pump running on a liquid that had given up a great deal of the protection it is made for — which is why the thing our technicians ask is how far you went, not how long your motor has been parked.

How much fuel your pump has pulled is what we are actually asking — not how long ago any of it was. So the call our engineers hope for sounds like this: diesel Peugeot 308, a couple of litres of unleaded, a couple of miles covered, now switched off outside Waitrose.

This is what a job in the car park outside White Hart generally looks like. We arrive at the car, ask what got in, about how much, and whether the engine has run since — these three answers determine most of the work. Then the tainted mix comes out of that tank, the fuel lines get cleaned, and the filter comes off where your BMW 1 Series has a serviceable one. Clean diesel goes in and the fuel system is bled. Then we start the engine, make sure it runs correctly, and you set off.

Petrol in a diesel does its damage as a share, which is the reason we ask at all: the same few litres resting 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 wants — so a stronger mix knocks more, smokes more, goes flatter. None of which means you need an answer prepared. Nearly nobody knows how full your tank was in a vehicle picked up two days ago, and our engineers 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 faster settled before than after. Then phone us about the Audi Q5 close to Brethern's Meeting Room (place of worship).

What occurs next is the issue. The engine at once pulls the petrol left waiting in your filter and the feed lines back round through the pump a second time, as draining a tank does nothing about fuel that has already left it. Drain it then put clean diesel in, a person certain will tell you — and that tip is only half right, because do it to a diesel Volvo XC60 parked up, Our Lady Queen of Heaven say, and the thing starts, which is what makes it sound reasonable. Phone us instead. We flush your circuit and take your filter off where the car has a workable one, and that's the difference between the vehicle being repaired and the car just starting.

At a forecourt: removing petrol from the diesel

Most of the job begins at the pump, so a big share of that gets completed on site. Still at Texaco? Then that's typically where it takes place. Station forecourts are routine for us, with the permission of the site.

At a garage, it gets halted with your engine never fired, and no place else does that. Everywhere else — a car park, a driveway, a lay-by — the vehicle was fired up and driven to get there, which means fuel was sucked from your tank, through the filter then into the high-pressure pump. That's not a catastrophe, and our engineers can still put it right where it is. It does mean your lines and the filter need rinsing as well as that tank, and that's decided by the few seconds between seeing your receipt and reaching for the keys.

Attendants will normally chip in pushing it out from the petrol pump, which lets the next customer get past. Take the offer. Firing the car over four car lengths? No.

Can our technicians serve your part of Frimley?

These same rounds bring us to Farnborough Green, Frimley Green, Hawley Lane, Frimley Ridge and Farnborough Street along with Frimley, which is a riverside town.

If yours is not on that list it doesn't mean we never come — there are separate pages for most towns around Surrey, and the ones listed above are merely the immediate neighbours. Ring us and enquire instead of guessing — boundaries above all, and anywhere a satnav can struggle with.

The map is the area this page covers. We operate roadside, on forecourts, on driveways and at car parks across all of that, and the vehicle never needs to travel to us.

Kerbside call-outs in Frimley

The opportunity to pull over anywhere suitable does not come to everyone. If you worked it out after setting off and ended up along the verge beside Church Road, or at a lay-by somewhere with the hazards going, that's a common call for us instead of an unusual one.

Safe where you are? Sit with it. Not fine? Get out and clear of it. Don't start it up to get to a better location. It will go — a diesel on petrol usually obliges — and each mile of obliging pulls the mix deeper into the system. Driving on causes your car far more harm than a technician heading out to an inconvenient location, and that's no problem for us.

Run it already? Pull in, and check this

under a mile from Frimley, the M3 is what matters here. A drop in power, a lumpy idle, smoke: those are the signs when they arrive, rather than a neat stop — and a misfuelled diesel will frequently take you onto it and some way along before anything feels wrong at all.

Come off at the next safe junction, turn off, and don't restart it to reposition. Long run? Anything near the under 50 miles to the closest city and you should presume the lot — filter, pump, injectors, all of it got to by the petrol. Say that on the call, because it affects what goes in the van.

A bit about Frimley

Frimley is a town situated in the north-west of Surrey, on the banks of the River Blackwater and the Basingstoke Canal. Frimley sits at an elevation of around 71 metres, with a mix of residential and green spaces. Frimley is located near several smaller communities, including Farnborough Green and Frimley Green, and is characterized by its predominantly detached housing stock. Frimley is also within commuting distance of London, being approximately 29.5 miles from the city centre.

Once we get to you around Frimley: what we do

  • The answers alter the work, which is why we ask before quoting: what was put in, how much of it, and whether the engine has run.
  • The contaminated mixture is drawn out of that tank.
  • Our technicians purge the fuel lines and clear the fuel filter, so what is remaining in your system is not what started the issue.
  • We pour fresh diesel in and prime your system.
  • It's run with fresh diesel in it, and our engineers check that it's running correctly.

That has your car ready to pull away. Our technicians do everything wherever the vehicle has ended up, which means it never needs to be taken to a garage, and if it has been caught quickly, it's very rare for there to be permanent damage.

AdBlue in a diesel tank around Frimley is a distinct matter

The issue isn't the same, though the first step is — don't crank it — if what got in was AdBlue rather than petrol. The lubrication a fuel system depends on is taken away by petrol, which weakens the diesel. AdBlue? Urea dissolved in water. Pour that in with your diesel and you get rust instead, plus build-up.

Our technicians deal with both, and AdBlue removal in Frimley has its own page with the full story — including why it is usually the more serious of the two.

Paying for a petrol-in-diesel drain in Frimley

Our engineers can't put one price on this page truthfully, since the job isn't one job. What moves it:

  • Started? Driven? Either answer matters more than anything else on this list.
  • Wrong fuel in, against what that tank takes — that proportion.
  • AdBlue or unleaded, whichever went in.
  • Where the vehicle is, and whether a van can safely get to and work on it.

The vehicle, the amount, whether it has run — give us those and the answer comes back firm instead of as a range. Vehicle at home, going nowhere, nothing time-critical about it — is ideal for that.

Questions our technicians hear about petrol in diesel in Frimley

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

Yes — forecourts are where a big portion of this happens. Tell us which one you are at when you ring and we'll tell you if our engineers can work there. With the site's agreement our technicians work at Shell and the other forecourts locally all the time.

How much petrol is too much for a diesel?

It hinges on the proportion instead of the litres, and much more on whether the engine has run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same question in the end: has that mix been sucked right through, or has it not?

I put petrol in my diesel and drove the vehicle. Now what?

Turn off somewhere safe, then keep it that way after you stop. Not restarting it is the single most helpful thing available to you now. Driving does shift the trouble out of the tank then into the pump and injectors, yes, and it remains salvageable far more frequently than drivers assume.

Is a fuel drain going to void my warranty?

A drain and flush carried out correctly isn't a modification and does not cancel a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause an argument with one, which is another reason to leave the car turned off.

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

What petrol has weakened isn't replaced by two-stroke oil, which is an old fix for a distinct issue. So no. The pump still has to put up with it, since your tank still has petrol in it after that.

Main dealers and petrol in a diesel

Not at all. We drain and flush the vehicle wherever it is, so there's no need to take it to a franchised dealer.

Is the car still with you?

Switched off is how the car stays.

Driven it already? Then somewhere safe, stop, turn off, and no restarting it later. Cold and still, a motor is in the best position available — and motorists fear this much more than the recovery rate warrants.
