Turnpike Lane: Put Petrol in a Diesel Car?
If you have not turned on the engine yet, don't. A fuel drain and nothing else is almost always what a vehicle requires while the petrol is still inside that tank and your engine has not yet been started, which is why it's the next few minutes that count, not how much was put in. Petrol in Diesel travels to the car wherever it has stopped in Turnpike Lane or the remainder of Greater London, on the forecourt, at the roadside or on a private drive, and drains and flushes it there. One call our way will be sufficient: our team can tell you what follows next. Do this first.
The next five minutes: petrol in a diesel
- Feed a petrol motor diesel and it will typically fail to run at all, and so the motorist stops there and so does the harm. Give a diesel petrol and the car starts, it idles, it drives off — fine for several miles. Drivers have that muddled, which is the part they get wrong about petrol in a diesel in particular. So never crank it. And if started, do not trust it: the fuel system is wearing down as you drive.
- Leave the ignition alone as well. Diesel does two jobs: it ignites, and before it ignites it greases the injection pump and those injectors. Petrol manages the first but not the second. Switching the ignition on is often all it takes to prime the system, which draws that petrol out of that tank then into precisely those parts.
- Topping up clears nothing. It leaves you a larger tank of the same mix, because a diesel fuel system will not tolerate petrol by percentage as that advice assumes — so never tip diesel on top to thin it. Octane is beside the point too: super unleaded is petrol.
- Stay put if it is sensible to. Hazards on, motor off, keep the car. Wherever you have stopped — the verge on Turnpike Mews, anywhere — a difficult spot for us is better than a started diesel, and nothing is quicker for us to deal with than a car that never moved.
- The van turning up rather than circling depends on two things: a postcode starting N8 0, and whatever is nearest to you with a label on it. Have both ready before you dial.
- Ring 0333 366 0103. Anticipate three questions — what went in, about how much, plus if the motor has been started. The replies decide all that follows.
Can petrol be taken out of your diesel at the forecourt?
The work starts at the pump, generally. Frequently the work finishes on site too. We operate on station forecourts all the time, with the site's consent, and so if you are still at Esso that's typically where the drain gets done.
A filling station is the single location this can be halted before your engine has fired. Anywhere else — a car park, a driveway, a lay-by — your car was started and driven to get there, which means fuel was sucked from that tank, through the fuel filter and into your high-pressure pump. That is not a calamity, and we can still put it right where it stands. It does mean the fuel lines and your filter need rinsing as well as your tank, and that is decided by the few seconds between checking the till receipt and reaching for the keys.
Push it out of the way if the staff volunteer, and they usually will. The next customer gets through the petrol pump, and that's worth doing. Firing the car over four vehicle lengths? Never.
Simple, these ones, and the reason is the distance: a mile at easy throttle draws very little fuel. Petrol into a diesel Ford Focus somewhere in Turnpike Lane, a boot loaded with shopping, and you stranded at Olive Tree Organic — phone. Exiting that spot is never worth another start. Your tank gets emptied where it sits, the lines cleaned, new diesel in, and you get home.
You'll be advised to shift the car clear of that gateway and fix it later. Please don't. On the zig-zags at North Harringay Primary School, a wrongly fuelled Mercedes C-Class running on diesel is in the way, and that is all it is. Start it three more times being polite and you have turned a tank into a fuel system: every start primes your lines, every prime pulls more petrol past your filter towards your pump. Let them complain. Phone.
Three answers settle much of the work: what went in, roughly how much, and whether the motor has run since. We ask for those answers when we arrive at the car in the car park outside The Toll Gate. Then the polluted mixture comes out of that tank, the fuel lines are rinsed, and where your Audi A3 has a replaceable filter, it comes off. When clean diesel is in and the system primed, we start it and make sure it runs smoothly before you pull away.
Don't drive it home to buy yourself time. You already have it: nothing gets worse whilst the vehicle sits, because a diesel BMW 1 Series left outside Ducketts Common is doing none of what it did on the way there. The pump has stopped turning.
Hire car? Company car? Ring them before us. Some agreements want the firm to approve the work, and that is much quicker dealt with up front than after that. Then ring us about the Kia Sportage, the diesel one, close to Willoughby Methodist Church. Do not worry that you can't say how full that tank was — nearly nobody can two days into a car, and it is something our engineers check on the spot. The reason for asking: harm from petrol in a diesel is a matter of proportion. A couple of litres in a nearly empty tank make a far stronger mix than in a full one, and petrol is built to resist the very thing a diesel needs of that, which is igniting when compressed. Stronger blend, more rattling, more smoke, flatter throttle.
Turnpike Lane and the places next to it
Hornsey, Noel Park, Wood Green, Harringay, West Green — all of them on our trips that take us across to Turnpike Lane as well, a residential suburb.
There are pages for the majority of locations in Greater London, and the ones named above are merely the closest neighbours — so yours being missing from that list says nothing at all about whether our technicians come. Ring us and check rather than guessing, above all when you are on the boundary or somewhere your satnav gets wrong.
The patch this page includes appears on this map. Every bit of it is territory we serve: a kerbside, a forecourt, a driveway, a car park. You never move the car anywhere.
Roadside stops across Turnpike Lane
Not everyone has the chance to stop somewhere safe. Hazards going in a lay-by somewhere, or stopped on the verge beside Turnpike Lane since you noticed after setting off — we take that call often enough that it's the usual kind.
Remain with the motor if it is sensible to be there, and clear of the vehicle if it isn't. It will frequently oblige. A diesel running on petrol limps along quite willingly, and that is the problem: start it up to reach somewhere better and the blend goes further into the system with every mile driven. Our van coming to an awkward place is no problem for us, and it's far better for your car than carrying on.
So you've driven it? Petrol in a diesel after a couple of miles
Here is where the M1 comes in — under 10 miles away from Turnpike Lane. A misfilled diesel will often take you onto it and some distance along before anything seems wrong, and the symptoms when they arrive are generally a loss of power, a lumpy idle and some smoke instead of a tidy stop.
Do not start it to move it. Get off at the first safe junction and turn off. On a longer trip — anything near the under 10 miles to the closest city — take it the contamination has been through the filter, the pump and your injectors, and mention it when you phone. It affects what our technicians bring.
All about Turnpike Lane
Turnpike Lane is a suburban area in north London, situated near the River Moselle and close to the cities of London and surrounding neighbourhoods such as Hornsey and Wood Green. Turnpike Lane sits at a relatively low elevation of around 25 metres, with its population of approximately 18789 people residing predominantly in flat dwellings. Turnpike Lane is located near several local amenities and transport links, including those connecting it to nearby Noel Park. Turnpike Lane forms part of the wider London urban landscape, with the city centre just 5.8 miles away.
What we do when our technicians get to you around Turnpike Lane
- Our technicians establish what got in, how much, and whether the motor has run. The replies change the work, which is why our engineers ask before pricing.
- Our engineers empty that tank of the polluted fuel.
- Fuel lines are rinsed through and your filter cleaned, leaving nothing in your system that started any of this.
- The fuel system gets bled, on new diesel.
- Your engine is fired up and checked to confirm it runs smoothly on fresh diesel.
From that point, you are ready to drive away. Our technicians do all of it wherever your car has ended up, which means it never has to go to a workshop, and if it has been noticed soon, it's very rare for there to be long-term damage.
AdBlue in a diesel tank in Turnpike Lane is a distinct matter
Don't crank it: that opening instruction stands whether what got in was AdBlue or petrol. What changes is this fault itself. Weakened diesel, and no lubrication left for the fuel system that depends on it. That is petrol. AdBlue is urea dissolved in water, and in a diesel tank it leads to rust and residue in its place.
Frequently the more significant of the two, AdBlue — and the detail lives on its own Turnpike Lane page. Both are ours to deal with.
What a petrol-in-diesel drain costs in Turnpike Lane
Frankly, no single figure fits on a page like this. This job varies. Here is what varies it:
- Started? Driven? Either answer counts more than anything else on this list.
- How much of the wrong fuel went in, measured against how much your tank takes.
- AdBlue or petrol, whichever got in.
- Whether our van can safely reach your vehicle and work on it, which rests on where the car is.
Tell us what the car is, how much got in, and whether your engine has run. A straight answer comes back, not a range. Not pressing, with the vehicle at home and going nowhere? Then does this job.
Turnpike Lane motorists ask us these about petrol in diesel
At a petrol station around Turnpike Lane, can you do a fuel drain there?
Much of what we do takes place nowhere else. So yes. Often, provided the site consents: Texaco, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that location is something our engineers answer there and then.
Is there a sensible quantity of petrol in a diesel?
Litres aren't the measure. Ratio is, and far more than either, it matters whether anything has been run. Five litres in a nearly empty tank is a separate situation from five in a full one — but either way, the thing that determines how much work is needed is if that mixture has been pulled through your fuel system.
I put petrol in my diesel and drove it. Now what?
Stop sensibly. Off. Nothing after that. Not restarting it is the single most useful thing available to you now. Driving does move the problem out of your tank then into the pump and injectors, yes, and it remains fixable much more regularly than drivers fear.
Fuel drains and manufacturer warranties
It's not an alteration, and so a drain and flush carried out properly doesn't cancel a manufacturer's warranty. Running a diesel on petrol is the thing likelier to cause a disagreement with one, which is another reason to leave it switched off.
Could I put some two-stroke in and just drive?
Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol thinned. No. Your tank still has petrol in it afterwards, and the pump still has to cope with it.
Does petrol in a diesel have to go to a main dealer?
You do not need one. The vehicle is drained and flushed wherever it is, with no need to take it to a main dealer.
Still with the vehicle?
Your engine remains off.
Turn it off somewhere safe then keep it off, if you have already driven it. Cold, still, going nowhere: that's the best position to be in. People fear this much more than they need to.
