Petrol in Diesel

Petrol in a Diesel Car in Highfield

If you have not turned on the motor yet, don't. A fuel drain and nothing else is nearly always what a car needs while the petrol is still inside your tank and your engine has not run, which is why it's the next few minutes that count, not how much went in. Petrol in Diesel goes to the vehicle wherever it has come to rest in Highfield or the rest of Gloucestershire, on the forecourt, by the roadside or on a drive, and drains and cleans it there. A single ring to us will be enough: our team can show you what follows after this. Do that right away.

Your first five minutes: petrol in a diesel

  • As you drive, the pump and the fuel injectors wear down. That's why you do not crank it, and why you never depend on it once it has started. The trick about petrol in a diesel specifically — the point people get wrong — is that it drives off fine for the first mile or two. Diesel in a petrol engine normally cannot run at all, which stops the person and stops the harm with them. This one lets you carry on.
  • Two jobs, diesel: it burns, and on the way through it keeps that high-pressure pump and injectors greased. Petrol only does the one. Which is why the car's ignition remains off too — switch it on and you often prime that system, and that's petrol exiting the tank for just those parts.
  • That guidance supposes a diesel fuel system accepts petrol by percentage. It doesn't. Put diesel on top and nothing at all is cleared; what you get is a bigger tank of the same blend. And no, the grade makes no difference — super unleaded is just petrol.
  • A car that has never shifted is the simplest one to handle, and so wait where you are if you reasonably can. Parked on the verge on Hillfield? Hazards on, then keep the vehicle there. An awkward place works for us better than a started motor.
  • A van turning up rather than circling depends on two things: a postcode that starts GL5 4, and whatever is next to you with a name on it. Get both prepared before you ring.
  • Call 0333 366 0103. Expect three things — what was put in, approximately how much, and whether your car has been started. Those replies shape all that happens next.

Can petrol be drained out of a diesel on the forecourt?

Most of the work begins at a forecourt, so a good share of that gets done on site. We work on station forecourts routinely, with the site's consent, and so if you're still at Esso that is typically where this drain takes place.

Before the engine has fired — a garage is the single spot it is halted. Anywhere else — a car park, a driveway, a lay-by — the car was fired up and driven to get there, which means fuel was sucked from that tank, through the fuel filter then into the high-pressure fuel pump. That is not a catastrophe, and our technicians can still sort it out where it is. It does mean the lines and the fuel filter need rinsing as well as your tank, and that is determined by the few seconds between reading the receipt and going for the keys.

Clear of the petrol pump, the next motorist can get past — so yes, let the staff help you move the car. Well worth doing. Starting it just to move four vehicle lengths isn't.

Coverage around Highfield

Those same rounds take us to Park End, Cainscross, Paganhill, Puckshole and Hamwell Leaze along with Highfield, which is a residential suburb.

We do come. Those names above are merely the nearest neighbours, and a page exists for the majority of towns across Gloucestershire, so an absence from the list isn't an absence from the coverage. Phone to enquire instead of guessing — boundaries above all, and anywhere your satnav may misread.

The area the page includes appears on the map. Kerbside, forecourt, drive, car park: all of that is territory our engineers work on, and none of it requires your vehicle to travel to us.

Stuck by the kerbside in Highfield

Some drivers get no suitable place to pull over at all. A common call for us and not an unusual one: worked out after setting off, finished up on the verge of Marling Crescent or at a lay-by with the hazard lights on.

Whether you stay beside the vehicle or step clear of it rests on whether being there is safe. Every mile a diesel obliges you for on petrol draws that mix further into the fuel system — and oblige it often will, which is why the motor does not get restarted to limp somewhere better. We will take the van to an inconvenient place without any trouble, and for the car that's far better than carrying on.

Three replies settle most of the work: what was put in, about how much, and whether your engine has run since. We ask for those answers when we reach the car in the car park at The Old Crown. After that the tainted blend comes out of your tank, the fuel lines are flushed, and where your Vauxhall Astra has a replaceable filter, it comes off. After fresh diesel is in and your system primed, we fire it up and make sure it runs correctly before you pull away.

Here's the whole mechanism. Diesel needs enough body to seal the close clearances it goes through, and petrol takes that away. That's it. Which explains the usual Rounders Field call — a diesel Citroen C3, out there without a murmur and back down on power, lumpy at idle, maybe a bit of smoke. Injection systems work hydraulically as well as chemically, so your fuel has to hold pressure and not just burn; weakened, it bleeds past those clearances and not building, and delivery comes weaker, later, less even than the motor was built round. Not a failing engine, though. Fuel that has stopped acting like diesel. Put that right and it stops.

Why we're blunt about not driving on: your pump waits ahead of the injectors, so whatever a worn pump loses travels downstream with your fuel. Leave the Kia Sportage near Church of the Holy Spirit and ring us.

Hire car or company car? Call them before you phone us — some agreements want the hire firm to approve the work, and sorting that out first is a great deal faster than sorting it later on. Then ring us about the Volvo XC60 by Maypole Hall, and don't worry that you can't say how full your tank was. Almost no one can, in a motor they picked up two days ago, and our technicians work it out there. The reason our technicians ask is that petrol in a diesel does its harm as a ratio: the same few litres in a nearly empty tank is a far stronger mixture than in a full one. Petrol is rated on how well it withstands igniting under pressure, which is the opposite of what a diesel needs — so the stronger the mixture, the more it rattles, smokes and goes flat.

Drain it then put new diesel in — that is the tip you will get, generally from a person sure of themselves, and it's half true. Do precisely that to a diesel Hyundai Tucson near Anti-Slavery Memorial Arch and it would start, which is what makes the tip sound sensible. What occurs next is the problem: the motor straight away draws the petrol still sitting in your filter and the feed lines straight back through the pump, as draining a tank does nothing about fuel that has already left it. Phone us instead. We flush the circuit and take the fuel filter off where the car has a serviceable one, which is the difference between your car being put right and the car just starting.

So you've run it? Petrol in a diesel over a few miles

The local M5 is the road that matters now, and it sits under 5 miles from Highfield. Some way along, and onto it in the first place: a misfuelled diesel will frequently do both before anything seems wrong. What you get then is seldom a tidy stop. Power ebbs away, the idle gets lumpy, and there may be smoke.

Do not restart it to reposition. Get off at the first safe junction then turn off. Assume the worst of it on a long run. Anything close to the under 10 miles to the nearest city, and the mixture has been through the fuel filter, through your pump, through the injectors. Say so when you phone. What our engineers bring differs.

About Highfield

Highfield is a suburban area located on the riverside in Gloucestershire, with a relatively low elevation of 73 metres. Highfield sits near the city of Gloucester, approximately 8 miles away, and is close to other nearby places such as Park End and Cainscross. Highfield has a population of around 4909 people and predominantly consists of semi-detached housing. Highfield is situated in the South West region of England, about 92 miles west of London.

What follows when we reach you around Highfield

  • Our technicians find out what was put in, how much, and whether your engine has run. The answers alter the work, which is why we ask before pricing.
  • The tainted mixture is drawn out of that tank.
  • Fuel lines are rinsed through and your filter cleaned, leaving nothing in your system that created any of this.
  • Our technicians pour new diesel in and prime the fuel system.
  • Once it's fired up, we make sure it runs smoothly on new diesel.

From there, you are ready to drive away. All of this is done where your car is, so it never needs to be taken to a workshop, and when it has been caught soon, lasting damage is very uncommon.

Highfield AdBlue removal is a different job

Never fire it up: that first instruction holds whether what was put in was AdBlue or petrol. What changes is this problem itself. Petrol does two things to diesel: weakens it, and strips out the lubrication your fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it brings corrosion and deposits in its place.

Our engineers cover both, and AdBlue removal around Highfield has its own page with the details — including why it's often the more significant of the two.

How much is a petrol-in-diesel fuel drain in Highfield?

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

  • Has it been started or driven? Nothing else counts for as much.
  • Wrong fuel in, against what your tank holds — that ratio.
  • Which was put in: unleaded or AdBlue.
  • Access: the car's position, and whether working on it there is safe for our van.

Tell us what your car is, how much got in, and if your motor has run. A firm answer comes back, not a range. Not urgent, with the car at home and going nowhere? Then is fine.

Things our engineers hear about petrol in diesel in Highfield

Fuel drains on a Highfield petrol station forecourt

Yes — forecourts are where a good portion of this happens. Regularly, provided the site agrees: Tesco, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our technicians can work in that spot is something our engineers answer there and then.

Is there a safe amount of petrol in a diesel?

Ratio decides it rather than litres — and more than either, whether the motor has run. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same question in the end: has that mixture been pulled right through, or has it not?

I put petrol in my diesel and drove it. What now?

Stop safely. Off. Nothing after that. It is fixable a lot more commonly than people expect, even though driving is what moves the problem from that tank into your pump and injectors — and the single most helpful thing you can do now isn't restart it.

Is a fuel drain going to void my warranty?

A manufacturer's warranty withstands a drain and flush done to a correct standard, which is no change at all. Another good reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a dispute with one.

Adding two-stroke oil, then driving home

No. It belongs to a separate problem from a different era, and petrol has thinned something no oil of that kind replaces. Later? Still petrol in the tank, and a pump that has to put up with the stuff.

Main dealers and petrol in a diesel

You don't need one. The vehicle is drained and flushed wherever it is, with no need to take it to a franchised dealer.

You, and your vehicle, still together?

Turned off is the way it stays.

Already driven it? Then pull in somewhere sensible, switch off, and let the vehicle stay that way. Cold, parked, going nowhere: that's the best place to be in. Drivers fear this a lot more than they need to.
