Binley: Put Petrol in a Diesel Car?
Petrol in Diesel drains and flushes misfuelled cars where they stand, on the forecourt, by the roadside or on a drive, across Binley and the remainder of West Midlands. The first thing to do is not to start the motor. While the engine has not been started and the fuel is still in the tank, a drain is almost always all it needs, and the coming few minutes determine that, not how much went in. Phone before all else starts, so you'll hear what comes after that.
What now? Petrol in a diesel, in order
- Do not crank it. Fired up anyway? Then never trust it. Diesel in a petrol motor normally will not run, and so the driver stops and the wear halts with them. Petrol in a diesel? It starts. It ticks over. It moves off fine, for several miles. Most people get that confused. It isn't fine — your fuel system is wearing every mile you cover.
- Leave the ignition alone as well. Diesel does two roles: it combusts, and before it burns it lubricates the high-pressure fuel pump and the injectors. Petrol handles the first but not the second. Flicking your ignition on is often enough to prime that system, which draws that petrol out of that tank and into exactly those parts.
- Do not pour diesel on top to dilute it. A diesel fuel system won't cope with petrol by percentage the way that advice suggests, and topping up removes nothing — it simply gives you a larger tank of the same mixture. The type makes no difference either: super unleaded is still petrol.
- Wait where you are if you reasonably can. A motor that has not moved is the simplest one to sort, and we would sooner travel to a tricky spot than have it started. If you are pulled up on the verge on Princethorpe Way, switch the hazards on and keep it there.
- Before you ring, gather your location. Anything nearest to you with a sign on it, plus a postcode beginning CV3 2 — that's what decides whether the technician turns up or circles.
- Three answers decide the entire call-out: the liquid you tipped in, the ballpark volume involved, plus if it has been turning since. Our number is 0333 366 0103.
Forecourt draining for petrol in a diesel
Plenty of the work begins at a forecourt, meaning a big share of that gets done at one. The drain normally gets done there and then. Still on the forecourt at BP? Given the owner's consent, that is a spot we work, and regularly.
No place other than a garage can this be spotted with the engine still cold. The few seconds between checking your receipt and going for the key determine how much needs flushing. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the vehicle was switched on and driven to get there, so fuel was drawn from the tank, through the fuel filter and into the high-pressure fuel pump. That means your lines and the fuel filter need rinsing as well as the tank. It's not a disaster, and our technicians can still put it right where the car sits.
Staff will generally pitch in pushing it out from the pump, which lets the next driver get past. Take the help. Four car lengths isn't worth a restart.
How much fuel your pump has drawn is what we're really asking — not how long ago any of that was. So the phone call our technicians hope for sounds like this: diesel Skoda Octavia, a few litres of unleaded, a couple of miles covered, now shut off at Costcutter.
You will be told to move the car out of the gateway and fix it later. Don't. On the zig-zags outside Ernesford Grange Primary School, a misfuelled Nissan Qashqai running on diesel is in the way, and that is all it is. Fire it up three more times being courteous and you have turned a tank into a fuel system: every start primes the lines, every prime draws more petrol beyond your filter on to your pump. Let them grumble. Call us.
Leave it overnight. Call us first thing. Nothing about a diesel Audi A3 parked in the parking area at Miners Arms degrades as it sits, tank of petrol or not, and the job remains a simple one right up until the moment it gets driven home. The question our technicians bring is about that trip there: a cold motor over a short hop is where petrol burns least well, and whatever fails to burn can find its way past the rings into the oil.
Phoning from near St Bartholemew's? Three things help us. The filler — which side of the car it's on. Room for our van next to you, without the road being blocked. And if anything has run since the fill-up. The location itself scarcely counts: on-street is where our engineers work most, and we'd far rather have a tight spot than a car somebody has driven somewhere simpler. Then it is a drain for the Vauxhall Astra, a filter change where there is one worth changing, lines flushed, fresh fuel put round the entire system. By now the worst of that is in the fuel lines and not your tank.
Hire car? Company car? Phone them before us. Some contracts want the firm to authorise the work, and that's much faster dealt with up front than after that. Then phone us about the Kia Sportage, the diesel one, close to Meredith Road Baptist Church. Don't worry that you cannot say how full the tank was — almost nobody can two days into a motor, and it's something our engineers establish on the spot. The reason for asking: damage from petrol in a diesel is a matter of share. A few litres in a nearly empty tank make a far stronger blend 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 mix, more knocking, more smoke, flatter throttle.
Binley and the places near it
Binley is a residential suburb, so our technicians head out to it and to the areas near it on those same runs: Stoke, Stoke Aldermoor, Church End, Willenhall and Pinley Gardens.
If yours isn't on the list it does not mean we never come — there are separate pages for nearly all locations in West Midlands, and the ones mentioned above are merely the closest neighbours. Guessing is the habit to skip, above all on the boundary or somewhere the satnav gets lost. Phone to check.
The map shows the patch the page includes. Roadside, forecourt, driveway, car park: the lot is territory our technicians cover, and none of it requires the vehicle to move to us.
Stranded on the roadside anywhere around Binley?
Not everybody gets a safe spot to stop. If you worked it out after setting off and landed along the verge on George Marston Road, or at a lay-by somewhere with the hazards flashing, that is a routine call for us rather than a rare one.
Remain beside your car if it's sensible to sit inside, and out of it if it isn't. It will often oblige. A diesel running on petrol limps along very willingly, and that is the problem: fire it up to reach somewhere better and that blend goes further into the system with every mile covered. Carrying on causes your car far more harm than our van heading out to an inconvenient place, and that is no trouble for us.
Petrol in a diesel, but the vehicle has moved
under 3 miles from Binley, your M69 is what matters now. Some way along, and onto it in the first place: a wrongly fuelled diesel will usually do both before anything seems wrong. What you get then is rarely a clean stop. Power ebbs away, your idle goes rough, and there may be smoke.
Take the next exit that is sensible, pull up there, and don't restart the car to reposition. On a longer trip — anything approaching the under 3 miles to the closest city — take it the contamination has been through your filter, the pump and the injectors, and tell us when you phone. It alters what our engineers bring.
Where's Binley?
Binley is a suburban area in the West Midlands, situated near the River Sowe and approximately 2.3 miles from Coventry city centre. Binley has a mix of terraced housing and is located at an elevation of around 80 metres, with nearby places including Stoke and Church End. Binley is part of the larger Coventry urban area, with easy access to the city's amenities. Binley sits within the West Midlands region, about 83.6 miles northwest of London.
What happens when we reach you in Binley
- The responses shape the work, which is why our technicians ask before pricing: what got in, how much of it, and whether your motor has run.
- Out goes the contaminated mixture.
- Lines cleaned, filter cleared. Whatever is left later on isn't the thing that created the problem.
- Fresh diesel goes in, and then the system gets bled.
- The engine is turned on and tested to make sure it runs correctly on clean diesel.
That leaves your car ready to set off. All of it is done where the car is, so it never needs to be taken to a workshop, and when it has been caught soon, long-term damage is very rare.
Binley AdBlue removal is a separate matter
AdBlue instead of petrol? Then the first instruction is unchanged — the motor stays off — while the issue beneath it is a different one altogether. Petrol does two things to diesel: weakens it, and takes away the lubrication the fuel system depends on. Urea dissolved in water, AdBlue, and in a diesel tank that brings rust and deposits.
Both are ours. There's a separate Binley page for AdBlue removal, with the details on it — including the reasons it usually turns out to be the worse of the two.
Budgeting for a petrol-in-diesel drain around Binley
What shifts the price is laid out below, because this job isn't one job and our engineers can't frankly put a single price on this page.
- Started? Driven? Either answer matters more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel got into it.
- AdBlue or unleaded, whichever got in.
- Where the vehicle is, and whether a van can safely get to and work on it.
Tell us what the car is, how much got in, and whether the motor has run. A clear answer comes back, not a range. If it isn't time-critical — the car is at home and going nowhere — is fine too.
Binley motorists ask us these about petrol in diesel
Fuel drains on a Binley petrol station forecourt
Yes — forecourts are where a fair part of this happens. Tell us which one you're at when you phone and we'll tell you whether our technicians can work there. With the station's consent our engineers visit Morrisons and the other forecourts locally all the time.
A couple of litres of petrol in a diesel — too much?
Whether your motor has run matters a lot more, though the proportion matters too, rather than the litres. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same query in the end: has that blend been sucked right through, or has it not?
I put petrol in my diesel and drove it. Now what?
Switch off somewhere safe, then keep it that way after you stop. It's fixable far more commonly than motorists expect, even though driving is what takes the trouble from the tank into your pump and injectors — and the single most helpful thing you can do now is not restart it.
Is a fuel drain going to void my warranty?
No. Carried out correctly, clearing and purging is no alteration at all, and the warranty from your manufacturer is unaffected by it. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave the car turned off.
Two-stroke oil in your tank, and then home?
No. Two-stroke oil is an old fix for a different fault and it does not replace what petrol has diluted. Your tank still has petrol in it later on, and the pump still has to cope with it.
Main dealers and petrol in a diesel
There is no need to take it to a main dealer, since our technicians drain and flush your car wherever it is.
Still with the vehicle?
That engine remains off.
If you have already driven the vehicle, pull over somewhere sensible, switch it off and leave it off. A parked, cold motor is the best position to be in, and this is recoverable from far more frequently than motorists assume.
