Ainsdale: Put Petrol in a Diesel Car?
With that tank still carrying the fuel and the engine not yet run, nearly every job takes only a drain, so leave the motor off. That result is settled in the minutes immediately after filling up, rather than by the amount that went in. Throughout Ainsdale and the rest of Merseyside, Petrol in Diesel drains your car and cleans it where it stands, whether by a roadside, on a driveway or at a forecourt. Call us and our engineers will explain what happens after that before you try anything else.
Your first five steps: petrol in a diesel
- Don't crank it. Started all the same? Then do not believe it. Diesel in a petrol vehicle generally won't run, and so the person stops and the wear ends with them. Petrol in a diesel? It starts. It idles. It pulls away normally, for a few miles. Most people get that muddled. It isn't okay — your fuel system is grinding every mile you cover.
- Two jobs, diesel: it ignites, and on the way through it keeps the high-pressure fuel pump and injectors lubricated. Petrol only does the one. Which is why the ignition stays off too — turn it on and you commonly prime that system, and that's petrol exiting that tank for exactly those components.
- That advice supposes a diesel fuel system accepts petrol by percentage. It won't. Add diesel on top and nothing at all is cleared; what you end with is a bigger tank of the same mixture. And no, the octane makes no difference — super unleaded is still petrol.
- Stay where you are if you safely can. A motor that hasn't moved is the easiest one to sort, and we'd sooner come to an odd location than have it started. If you are pulled up on the verge on Village Row, turn the hazards on and keep it there.
- The van turning up instead of circling turns on two things: a postcode starting PR8 3, and whatever is next to you with a label on it. Have both ready before you dial.
- What was put in, approximately how many litres, and whether the car has started — these three replies shape your whole call-out. Dial 0333 366 0103 then tell us.
Never take it home. Petrol-thinned diesel has run through that high-pressure pump in real quantity on the way in, and the trip back would about double that for nothing at all. Phone us — the platform is good. There's no need to stand over the Volkswagen Golf outside the nearest station while the work happens, and our team would very much rather talk to you tonight than realise on Monday.
Diesel Renault Megane. Some litres of unleaded. Done a couple of miles. Shut off now, at Co-op Food. That is the call our technicians want, because the real question underneath it is about volume through your pump instead of hours on the clock.
Hazards on. Motor off. Ring us. It's twenty to nine at the gates of Ainsdale St John's Church of England Primary School, you're late, and your receipt says unleaded — and even though three miles in the Peugeot 308 seems like nothing, fuel gets delivered on demand, and a frantic drive asks for plenty of it.
Don't drive it home to buy yourself time. You already have it: nothing gets worse whilst your car sits, since a diesel Mercedes A-Class parked at Ainsdale Village Park is doing none of what it did on the way there. Your pump has stopped turning.
By this point the tank is not where most of the damage is. Once a diesel has run, that mix is in the filter, the fuel lines, the pump and its rail — and it doesn't come back out with that tank contents. A diesel Citroen C4 Picasso that made it near Ainsdale Methodist Church needs your circuit purged, not drained.
Clearing petrol from the diesel on the forecourt
Much of the job begins at a pump, so a large part of it gets completed on site. Still at Shell? Then that is generally where it takes place. Petrol station forecourts are normal for us, with the agreement of the owner.
The forecourt is the one place this is stopped before your engine has started. We can still sort it out where it stands, even away from the forecourt. In a car park, on a private drive or in a lay-by, your car has been switched on and driven there, and that sucked fuel through the filter and into the high-pressure fuel pump, all the way from that tank. None of that is a disaster, although the flush then has to reach past that tank to the lines and your filter, and the few seconds between reading the receipt and going for your key are what settle that.
Staff will generally help out pushing it away from the petrol pump, which lets the next motorist get past. Welcome the offer. Shifting the car four bays does not justify firing it.
Ainsdale plus the areas next to it
Ainsdale is a residential suburb, and we are out to the town and to the villages near it on the same runs: Woodvale, Ainsdale-on-Sea, Hillside, Birkdale and Freshfield.
We do come. The places above are just the nearest neighbours, and a page exists for nearly all places around Merseyside, so an absence from the list isn't an absence from our coverage. Guessing is the thing to avoid, particularly on a border or somewhere a satnav gets lost. Ring us to check.
The ground the page covers appears on the map. Kerbside, forecourt, drive, car park: all of that is ground we cover, and none of that asks your car to come to us.
Stranded at the roadside around Ainsdale
Not everybody has a sensible spot to pull over. Hazards going at a lay-by somewhere, or pulled onto the verge of Burnley Road as you realised after setting off — our technicians take that call so often that it's the normal kind.
Whether you wait by the car or keep away from it hangs on if sitting in it is wise. Every mile a diesel obliges you for on petrol pulls that blend further into your fuel system — and oblige it frequently will, which is why your engine does not get restarted to limp somewhere better. Carrying on does the car far more harm than our van heading out to an awkward spot, and that is no trouble for us.
A couple of miles on petrol in a diesel: what next?
Here is where your M58 comes in, under 10 miles from Ainsdale. A wrongly fuelled diesel will often get you onto it and some way along before anything feels wrong, while the signs when they arrive are typically a drop in power, a lumpy idle and smoke instead of a neat stop.
The first sensible exit is the one to take. Turn off there, then leave the restarting alone. On a longer run — anything approaching the under 15 miles to the nearest city — assume the contamination has been through the fuel filter, your pump and your injectors, and tell us when you ring. It alters what our engineers bring.
A bit about Ainsdale
Ainsdale is a suburban area located on the coast of Merseyside, with Ainsdale sitting near the mouth of the River Alt and looking out over the Irish Sea. Ainsdale has a relatively low elevation of 16 metres above sea level and Ainsdale is situated approximately 13.6 miles north of Liverpool. Ainsdale is characterised by its predominantly detached housing stock and Ainsdale is close to nearby places such as Woodvale and Hillside.
Our visit in Ainsdale, step by step
- We ask first, price after. What went in? How much? Has your engine run? Those responses shape what the work actually is.
- We clear the tank of the tainted mixture.
- Fuel lines are rinsed through and your filter cleared, leaving nothing in the fuel system that started any of this.
- The fuel system gets primed, on new diesel.
- Our technicians start the car and check it runs properly on clean diesel.
From there, you're ready to drive away. There's no need to go to a garage at any stage, since the work is all done where the car is, and when it's noticed early, lasting damage is very unusual.
AdBlue in the diesel tank instead, in Ainsdale?
AdBlue rather than petrol? Then the first instruction is unchanged — your engine stays off — whereas the issue underneath it is a distinct one altogether. Petrol dilutes your diesel and strips the protection the fuel system relies on. Rust and deposits are what a diesel tank gets instead, because AdBlue is urea dissolved in water.
We cover both, and AdBlue removal in Ainsdale has its own page with the details — including why it's usually the more significant of the two.
Paying for a petrol-in-diesel fuel drain around Ainsdale
What shifts the figure is laid out below, as the job isn't one job and we can't truthfully put a single price on this page.
- Whether your engine has been started or driven. This is the big one.
- How much of the wrong fuel was put in, weighed against how much that tank can hold.
- AdBlue or petrol, whichever was put in.
- Where is it? And can our van get to it and work there safely?
The vehicle, the quantity, whether it has run — give us those and the answer comes back clear instead of as a range. For the car at home that is going nowhere and isn't time-critical, works too.
Questions we get about petrol in diesel around Ainsdale
I'm on a forecourt in Ainsdale. Can you drain the vehicle here?
Yes — forecourts are where a big portion of this takes place. Our engineers attend EG On the Move and the other forecourts locally routinely, with the station's consent — tell us which one you are at when you ring and we'll tell you if we can work there.
Is there a sensible quantity of petrol in a diesel?
It rests on the ratio rather than the litres, and much more on whether your motor has run. Five litres in an almost empty tank is a different matter from five in a full one — but either way, the thing that settles how much work is required is if that blend has been pulled through your fuel system.
I put petrol in my diesel and drove the car. Now what?
Stop safely. Off. Nothing after that. Driving is what takes the problem from that tank into the pump and injectors — but it's recoverable far more commonly than drivers fear, and the single most useful thing you can do now is not restart it.
Is a fuel drain going to void my warranty?
A drain and flush carried out correctly is not a change and doesn't void a manufacturer's warranty. What is likelier to start a dispute is a diesel that has been run on petrol. One more good reason for your engine to stay off.
Can I just add two-stroke oil and drive home?
Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol diluted. No. The tank still has petrol in it after that, and the pump still has to live with it.
Main dealers and petrol in a diesel
Not at all. Our technicians drain and clean your car wherever it is, so there's no need to take it to a main dealer.
Is the car still with you?
Do not switch your engine on again.
Switch it off somewhere sensible then leave it off, if you have already driven it. A stationary, cold motor is the best position to be in, and this is recoverable from a lot more regularly than drivers fear.
