Weakey: Put Petrol in a Diesel Car?
If you have not turned on your engine yet, don't. A fuel drain and nothing else is nearly always what a vehicle requires while the fuel is still sitting in that tank and the motor has not run, which is why it's the coming few minutes that count, not how much went in. Petrol in Diesel comes to your car wherever it has come to rest in Weakey or the rest of Greater Manchester, on the forecourt, by the roadside or on a drive, and drains and flushes it there. Just one call our way will be plenty: our technicians shall show you what happens next. Do it first.
Petrol in a diesel: what to try first
- While you drive, the pump and the fuel injectors wear. This is why you do not crank it, and why you never believe it once it has started. The trick about petrol in a diesel specifically — the part drivers get wrong — is that it drives off happily for the first mile or two. Diesel in a petrol motor generally can't run at all, which stops the person and stops the damage with them. This one lets you drive on.
- Two things, diesel: it ignites, and on the way through it keeps that high-pressure pump and injectors protected. Petrol only does the one. That is why the car's ignition stays off also — turn it on and you often prime the system, and that's petrol exiting the tank for just those parts.
- Never water down it. Diesel poured on top takes out nothing, and so all you get is more of what was already there, since percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Still petrol. The grade makes no difference.
- A vehicle that has never moved is the quickest one to deal with, and so remain where you are if you reasonably can. Stopped on the verge on Moor Crescent? Hazards on, and leave it there. A tricky place works for us better than a started diesel.
- Check where you are before calling. A postcode starting OL3 5, and the name of whatever is next to you. Otherwise our van circles instead of arriving.
- Phone 0333 366 0103. Expect three queries — what went in, roughly how much, plus if your car has been started. The answers shape whatever comes after.
Clearing petrol from your diesel on the forecourt
Pumps are where the job mostly begins, and where a big part of that finishes. Still at Gulf? Then that is generally where it happens. Garage forecourts are everyday for us, with the agreement of the owner.
Nowhere but a forecourt can the mistake be caught with your engine still unrun. The few seconds between seeing the till receipt and going for your key decide how much needs rinsing. Anywhere other than the forecourt — a car park, a drive, a lay-by — the vehicle was switched on and driven to get there, so fuel was pulled from the tank, through the filter and into the high-pressure pump. That means your lines and the fuel filter need rinsing as well as your tank. It is not a calamity, and our engineers can still put it right where the vehicle sits.
Attendants will normally chip in pushing it clear of the petrol pump, which lets the next customer get by. Accept the offer. Four car lengths isn't worth a start.
The tricky part is that bay, not the fuel. Cars either side of you, a trolley shelter behind, and from time to time a height barrier on the way in that decides whether our van can reach you at all — so when you call from a car park like the one outside Tesco, tell us how much clearance there's about you and which way round your car is. Those we cover regularly. Should there be no space to work beside your diesel Skoda Octavia, it gets rolled with your engine off, and not out of pedantry over a few seconds of running: priming happens at every start, more of that mix departs that tank for the pump, and two shunts into a nicer space have quietly made a harder job of what was simply a motor sitting still.
A diesel pump supplies fuel to demand, and a frantic morning dash needs plenty — so three miles in the BMW 3 Series sounds like nothing and isn't. Twenty to nine at the gates of Diggle School, already late, the receipt in your hand saying unleaded: hazards on, ignition off, call us.
Why so direct about leaving your keys alone? Because the pump is upstream of your injectors, and a worn one sends whatever it loses onward with your fuel. Call us. Leave the Mercedes E-Class by Thomas Telford.
Switch off where you have stopped, and do not restart it to find somewhere better — near Kilngreen Church or anywhere at all. Knocking, an uneven idle, white smoke and a limp throttle are a misfuelled diesel Audi A3 telling you what's wrong.
A person sure of themselves will tell you to drain the vehicle then put clean diesel in. Half true, that. Try it on a diesel Ford Kuga close to St Chad and your engine will start — which is precisely why it sounds like sense. Here's the catch: there is petrol left in the fuel filter and the feed lines, and the first thing your engine does is draw it back through the pump a second time. Emptying a tank achieves nothing about fuel that already left that tank. Ring us. Your circuit gets rinsed, the filter comes off where there is one worth removing, and that is what separates a fixed vehicle from one that simply starts.
Can our technicians serve your side of Weakey?
Diggle, Marslands, Holly Grove, Harrop Green, Woolroad — each of them on the rounds that carry us across to Weakey too, a residential suburb.
Our technicians do come. The places above are just the nearest neighbours, and a page exists for the majority of places across Greater Manchester, so an absence from the list is not an absence from our coverage. Presuming is the thing to avoid, especially on the border or somewhere your satnav goes wrong. Phone to ask.
The patch the page spans sits on the map. The car does not need to travel to us. Our technicians work across all of that — roadside, forecourts, driveways, car parks.
Kerbside breakdowns around Weakey
A chance to pull in anywhere sensible does not come to everybody. Hazards going at a lay-by somewhere, or pulled onto the verge on Lower Wrigley Green since you realised after setting off — our technicians take that call so often that it is the usual kind.
Wait beside the car when it's sensible to wait there, and out of the vehicle if it isn't. Don't start up your engine to limp the car somewhere safer — a diesel running on petrol will frequently oblige, and every mile it obliges for is drawing the mixture further into the fuel system. However inconvenient the place, it is no trouble for us to come to it, and that's much better for the vehicle than carrying on.
Petrol in a diesel, and the vehicle has gone
under 5 miles out of Weakey, your M62 is what matters here. A wrongly fuelled diesel will frequently take you onto it and some distance along before anything feels wrong, while the symptoms when they come are normally a loss of power, a lumpy idle and smoke rather than a tidy stop.
The first sensible exit is the one to take. Turn off there, and leave the restarting alone. Long run? Anything close to the under 15 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it got to by the mixture. Say that on the call, as it affects what goes in the van.
Weakey itself
Weakey is a suburban area in Greater Manchester, situated near the River Tame and close to the Pennine foothills. Weakey sits at an elevation of 191 metres, with views across the surrounding countryside. Weakey is characterized by its semi-detached housing stock and is located near other local places such as Diggle and Marslands. Weakey is approximately 11.6 miles from Manchester, making it a commuter base for the city.
Once our engineers arrive with you in Weakey: what we do
- Our engineers ask first, price after. What got in? How much? Has the engine run? Those replies alter what the work actually is.
- The polluted mixture comes from that tank.
- What is left in the system shouldn't be what caused the issue, so the lines get flushed and the fuel filter cleaned.
- Bleeding the system follows, once fresh diesel is in.
- It is started with fresh diesel in it, and we confirm that it's running smoothly.
From there, you are ready to set off. Our technicians do all of it wherever the car has stopped, which means it never has to be taken to a garage, and if it has been spotted early, it is very unusual for there to be permanent damage.
Weakey AdBlue removal is a distinct problem
If what got in was AdBlue instead of petrol, the opening instruction is unchanged — do not crank it — but this problem is not. Petrol does two things to diesel: weakens it, and strips out the lubrication the system relies on. AdBlue is urea dissolved in water, and in a diesel tank it leads to rust and build-up instead.
Both are ours. There's a separate Weakey page for AdBlue removal, with the full story on it — including the reasons it often turns out to be the worse of the two.
Weakey pricing for a petrol-in-diesel drain
What moves the price is laid out below, since this job is not one job and our engineers cannot truthfully put a single figure on this page.
- Has it been run or driven? Nothing else matters for as much.
- The tank's capacity, set against how much of the wrong fuel got into it.
- AdBlue or petrol, whichever went in.
- Access: the car's position, and if working on it there's sensible for our van.
A straight answer rather than a range is what you get for telling us three things: your car, the amount, and if it has run. If it's not pressing — the car is at home and going nowhere — is fine too.
Petrol in diesel: everyday queries around Weakey
Fuel drains on a Weakey petrol station forecourt
Yes, and it is where a big share of this work gets done. Our engineers visit Shell and the other forecourts around town all the time, with the station's permission — tell us which one you're at when you phone and we will tell you whether we can work there.
Is there a sensible quantity of petrol in a diesel?
Litres are not the measure. Proportion is, and a lot more than either, it matters if anything has been run. Five litres in a nearly empty tank is a distinct matter from five in a full one — but either way, the thing that settles how much work is needed is if that blend has been pulled through the system.
Already driven it with petrol in your diesel? What then?
Stop safely. Off. Nothing after that. Driving shifts the issue along — out of the tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you is not restarting it.
Will a fuel drain void my warranty?
A manufacturer's warranty survives a drain and flush done to a correct standard, which is no change at all. What is likelier to start a disagreement is a diesel that has been run on petrol. One more good reason for the motor to remain off.
Two-stroke oil in the tank, and then home?
No. Two-stroke oil is an old fix for a different issue and it doesn't restore what petrol has weakened. After that? Still petrol in that tank, and a pump that has to cope with the stuff.
Does petrol in a diesel have to go to a main dealer?
Wherever the car is, we drain and flush it there, so a trip to the main dealer does not come into it.
Standing next to it?
Switched off is how the car remains.
Turn it off somewhere sensible and leave it off, if you have already driven it. Cold and stationary, a motor is in the best place available — and drivers fear this a lot more than the recovery rate warrants.
