Put Petrol in a Diesel Car in Exley? Don't Start It
With the tank still holding the fuel and the engine not yet turned over, almost every job needs only a drain, so leave the engine off. That result is determined in the minutes straight after the fill-up, and not by the amount that was put in. Throughout Exley and the remainder of West Yorkshire, Petrol in Diesel drains your car and flushes it where it stands, whether by a roadside, on a drive or at a forecourt. A single call to us will be enough: we will tell you what follows from here. Make this straight away.
What to do now about petrol in a diesel
- Feed a petrol engine diesel and it will typically not run at all, and so the motorist stops there and so does the wear. Feed a diesel petrol and the car starts, it ticks over, it drives off — all right for several miles. People have that muddled, which is the thing they get wrong about petrol in a diesel specifically. So never fire it up. And having started, don't rely on it: your fuel system is wearing whenever you drive.
- Leave the car's ignition off as well. Diesel has two jobs: it combusts, and before it ignites it lubricates your high-pressure fuel pump and those injectors. Petrol manages the first and not the second. Turning the car's ignition on is commonly enough to prime the system, which moves this petrol out of that tank and into precisely those parts.
- Topping up takes out nothing. It gives you a larger tank of the same mixture, since a diesel fuel system does not cope with petrol by percentage as that advice suggests — so do not add diesel on top to thin it. Grade is beside the point too: super unleaded is petrol.
- Sit tight if it's wise to. Hazards on, ignition off, keep the car. Wherever you have stopped — the verge on Chevinedge Crescent, anywhere — a tricky location for us trumps a started diesel, and nothing is quicker for us to sort out than a vehicle that never moved.
- Have your whereabouts prepared before you phone. A postcode starting HX3 9 and whatever is nearest to you with a label on it is the difference between the van turning up and the van circling.
- Dial 0333 366 0103. Say what was put in, roughly how much, plus if the car has fired. Those three answers determine the full job.
Pump-side draining for petrol in a diesel
It starts at the pump, mostly. Frequently it finishes at one as well. If you are still on the forecourt at Shell, that is generally where the drain takes place — we work on station forecourts all the time, with the owner's consent.
Before your motor has started — the forecourt is the single setting this ends up spotted. Everywhere else — a car park, a driveway, a lay-by — the vehicle was started and moved to get there, which means fuel was drawn from that tank, through the fuel filter then into the high-pressure fuel pump. That is not a calamity, and our technicians can still sort it out where it is. It does mean your lines and the filter need rinsing as well as your tank, and that's settled by the few seconds between checking the receipt and reaching for your key.
The staff will usually happily move the vehicle out from the petrol pump so the next motorist can get past. It is worth doing. Four car lengths is not worth the risk.
How much fuel the pump has drawn is what we're really asking — not how long ago any of that was. So the phone call our engineers hope for runs like this: diesel Volkswagen Passat, a couple of litres of unleaded, a couple of miles driven, now switched off at Morrisons.
Twenty to nine outside All Saints' CofE Primary School, running late, and your receipt in your hand shows unleaded. Hazards on, engine off, call us. Three miles in your Skoda Octavia seems like nothing, but a diesel pump supplies fuel to demand — and a rushed morning run demands plenty.
Three answers decide most of the work: what went in, roughly how much, and whether the engine has run since. We ask for those answers as soon as we reach the vehicle in the car park at The Standard of Freedom. Next the tainted mixture comes out of that tank, the fuel lines are rinsed, and where your Nissan Qashqai has a replaceable filter, it comes off. When new diesel is in and the system bled, our technicians start it and confirm it runs properly before you drive away.
None of it is your engine failing. That's the bit worth hearing, and it's why the usual Bankhouse Wood call ends better than it sounds: a diesel Ford Focus drives out there without fuss, comes back with the power gone, the idle rough and possibly a little smoke, and the cause is your fuel no longer behaving like diesel. Diesel has to be thick enough to seal the precision components it passes through; petrol thins it; and a diesel injection system is hydraulic as much as chemical, needing the fuel to hold pressure rather than only to burn. So pressure that should build then stay built leaks past tolerances, delivery shows up weaker and later and less even than built, and all of that stops once the fuel is put right.
Hire car? Company car? Phone them before us. Some agreements want the firm to authorise the work, and that is much faster dealt with up front than later on. Then call us about the Audi A3, the diesel one, close to All Saints. Don't worry that you cannot say how full the tank was — almost nobody can two days into a motor, and it is something our engineers work out on the spot. The reason for asking: damage from petrol in a diesel is a matter of ratio. A few 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 it, which is igniting when compressed. Stronger mixture, more rattling, more smoke, flatter throttle.
Exley plus the places next to it
Being a residential suburb, Exley sees a routine call, while the places nearby come along on that same round: Salterhebble and Siddal, Skircoat Green and Lindwell, Copley.
Not on the list? It says nothing. The names above are only the nearest few, and nearly all towns across West Yorkshire have a page of their own somewhere on this site. Close to a border, or anywhere your satnav struggles with? Call us and ask rather than guessing.
The area this page includes is on our map. We work at the roadside, at forecourts, on driveways and in car parks across all of that, and the car does not need to move to us.
Stranded by the kerb somewhere around Exley?
Not everyone gets a chance to pull over somewhere sensible. A normal call for us rather than an unusual one: noticed after setting off, finished up along the verge beside Exley Gardens or at a lay-by with the hazards flashing.
Sit by your car when it is safe to be in it, yet clear of the car when it is not. It will often oblige. A diesel running on petrol limps along very willingly, and that is the trouble: start it up to reach somewhere safer and that mix goes further into the fuel system with every mile covered. Pressing on causes your car far more harm than a van driving out to an inconvenient location, and that's no bother for us.
Petrol in a diesel, and your car has travelled
Your M62 is the one that matters here, and lies under 3 miles from Exley. A wrongly fuelled diesel will often take you onto it and some distance along before anything seems wrong, and the symptoms when they arrive are normally a drop in power, a lumpy idle and smoke instead of a neat stop.
Take the first exit that's safe, pull up there, and don't start the car to reposition. On a longer trip — anything approaching the under 10 miles to the nearest city — take it the contamination has been through your filter, your pump and your injectors, and mention it when you call. It affects what our engineers bring.
Exley itself
Exley is a suburban area in West Yorkshire, situated near the River Calder and approximately 7.5 miles from Bradford. Exley sits at an elevation of around 120 metres, with semi-detached housing being the predominant type of accommodation in the area. Exley is located near other local places such as Salterhebble, Siddal, and Skircoat Green, and is about 167.7 miles from London.
What our technicians do when we get to you around Exley
- Our engineers check what got in, how much, and whether the motor has run. The replies alter the work, which is why our technicians ask before quoting.
- That tank gets drained completely.
- Fuel lines are rinsed through and the fuel filter cleaned, leaving nothing in the fuel system that caused any of this.
- The system gets bled, on clean diesel.
- Once it's fired up, our technicians confirm it runs smoothly on clean diesel.
Then it's ready to pull away. There's no need for a garage at any point, since the work is all done where the vehicle is, and when it's caught early, lasting damage is very unusual.
AdBlue in the diesel tank by mistake, in Exley?
The problem is not the same, though the opening instruction is — don't start it — if what went in was AdBlue rather than petrol. Thinned diesel, and no protection left for your fuel system that relies on it. That's petrol. Urea in water, AdBlue, and in a diesel tank that leads to rust and build-up.
AdBlue removal in Exley has a page of its own with the detail on it, including why it is usually the more serious of the two. Our technicians cover both.
Exley prices for a petrol-in-diesel drain
Our engineers cannot put one figure on this page truthfully, because this job is not one job. What moves it:
- Whether your motor has been started or driven. This is the big one.
- How much of the wrong fuel went in, measured against how much the tank can hold.
- Which went in: unleaded or AdBlue.
- Whether a van can safely get to your vehicle and work on it, which depends on where your vehicle is.
Tell us what your vehicle is, how much went in, and whether your engine has run. A straight answer comes back, not a range. Not time-critical, with the vehicle at home and going nowhere? Then does this job.
Questions our engineers hear about petrol in diesel around Exley
At a petrol station around Exley, can you do a fuel drain there?
Yes — forecourts are where a good part of this happens. Tell us which one you're at when you ring and we'll tell you if our technicians can work there. With the site's consent we visit Morrisons and the other forecourts nearby routinely.
A couple of litres of petrol in a diesel — too much?
It rests on the ratio instead of the litres, and a lot more on whether the motor has run. An almost empty tank with five litres in it, against a full one with the same five: different scenarios, of course. Either way, the work needed comes down to one thing, which is whether the system has had that mixture drawn through it.
Petrol in my diesel, and I have driven it
Somewhere safe, then stop, then turn off and leave it off. Not restarting it is the single most helpful thing available to you now. Driving does move the trouble out of the tank and into the pump and injectors, yes, and it stays fixable far more regularly than drivers expect.
Fuel drains and manufacturer warranties
No. Carried out correctly, emptying and cleaning is no change at all, and the warranty from your manufacturer is unaffected by it. What is likelier to start an argument is a diesel that has been run on petrol. One more reason for your engine to stay off.
Adding two-stroke oil, then driving home
No. It belongs to a distinct problem from a separate era, and petrol has thinned something no oil of that kind puts back. Petrol stays in that tank later, whatever else goes in, and your pump gets no reprieve from it.
Main dealers and petrol in a diesel
Wherever your car is, we drain and flush it there, so a visit to the main dealer doesn't come into it.
Is your car still with you?
Keep the car switched off.
Switch it off somewhere safe and keep it off, if you have already driven it. Cold, stationary, going nowhere: that is the best place to be in. People fear this a lot more than they need to.
