Maney: Put Petrol in a Diesel Car?
Don't turn on your engine. While the fuel is still in that tank and your engine has not been started, a tank drain is nearly always all it needs — and that is determined in the following few minutes, not by how much was put in. Petrol in Diesel drains and cleans misfuelled cars where they are, throughout Maney and the rest of West Midlands, on the forecourt, by the roadside or on a driveway. Ring us before anything else starts, and you will hear what comes from there.
What next? Petrol in a diesel, step by step
- Give a petrol motor diesel and it will normally not run at all, and so the person stops there and so does the wear. Give a diesel petrol and the engine starts, it idles, it drives off — fine enough for a few miles. Motorists have that muddled, which is the thing they get wrong about petrol in a diesel specifically. So never start the car. And having started, don't rely on it: that fuel system is wearing whenever you drive.
- Two tasks, diesel: it burns, and on the way through it keeps your high-pressure fuel pump and injectors protected. Petrol only does the one. Which is why your ignition remains off also — switch it on and you usually prime that system, and that's petrol leaving the tank for precisely those parts.
- Never pour diesel on top to thin it. A diesel fuel system will not accept petrol by percentage in the way that advice presumes, and topping up removes nothing — it simply gives you a fuller tank of the same mixture. The octane makes no difference either: super unleaded is simply petrol.
- We would rather come to a tricky place than have it started — so if you sensibly can, stay put. Nothing is simpler to sort out than a car that has never shifted. On the verge on Kathleen Road, that means hazards on then leave it.
- Before you dial, gather your position. Anything nearest to you with a sign on it, plus a postcode that starts B72 1 — that's what decides whether our van arrives or circles.
- Call 0333 366 0103. Tell us what got in, about how much, and also whether your car has fired. Those three details shape your whole job.
The trip back would more or less double it, for no gain at all. One commute has already pushed a real amount of petrol-thinned diesel through the high-pressure fuel pump of your Volkswagen Golf. So leave the car where it stands. Ring us from the platform if that's quicker — no one needs you standing over the car outside Sutton Coldfield while our technicians get on, and tonight trumps finding out on Monday.
Car parks like the one at Aldi are somewhere our engineers attend regularly, and your fuel is seldom the awkward part. That bay is: motors either side, a trolley shelter behind, occasionally a height barrier on the way in that decides whether a van can access you at all. So tell us how penned in you are when you call, and which way the vehicle is facing. When our technicians cannot work beside your diesel Renault Clio we will roll the car without firing it — and that isn't pedantry about a couple of seconds of running. Each start primes that fuel system and pulls more of the blend out of that tank and toward the pump, so a car shunted twice into a roomier bay has silently turned into a bigger job than one left exactly where it stopped.
Do not drive it home to buy yourself time. You already have it: nothing gets worse whilst the car waits, as a diesel Nissan Qashqai parked outside Trinity Park is doing none of what it did on the way there. Your pump has stopped turning.
Why we're firm about not driving on: your pump sits ahead of the injectors, and so whatever a wearing pump loses passes downstream with the fuel. Leave the Mercedes C-Class near Methodist Church and ring us.
Repaired and starting aren't the same thing, and the difference is your circuit: we flush it, and take the filter off where there's a workable one. Compare that with the confident tip you will get — drain the car, refill with new diesel. Only half right. Do precisely that to a diesel Audi A3 by Elmsdale Social Club and it'll start, which is precisely why the tip sounds plausible. Then the motor pulls the petrol left behind in your filter, and in the feed lines, straight back through the pump, since emptying a tank does nothing whatever about fuel that has already left it. Phone us instead.
Pump-side draining for petrol in a diesel
A large portion of the work ends up done at the pump, since that is where it mostly starts. If you're still at the forecourt at Texaco, that is typically where the drain takes place — we operate on garage forecourts routinely, with the station's permission.
At a forecourt, this is spotted with your motor never started, and nowhere else manages it. Anywhere else — a car park, a drive, a lay-by — the car was started and moved to get there, which means fuel was pulled from that tank, through the fuel filter then into the high-pressure fuel pump. That's not a disaster, and our technicians can still put it right where it is. It does mean the fuel lines and your filter need rinsing as well as the tank, and that is settled by the few seconds between reading the receipt and reaching for your key.
Out from the pump, the next motorist can get by — so yes, let the staff help you push the car. Worth it. Firing the car just to roll four vehicle lengths is not.
Maney and the places near it
These same runs take us to Royal Sutton Coldfield, Sutton Coldfield, Tudor Hill, Four Oaks Park and Wylde Green along with Maney, which is a residential suburb.
Our engineers do come. Those names above are only the immediate neighbours, and a page is there for nearly all places across West Midlands, and so an absence from the list isn't an absence from our coverage. Ring us to enquire instead of guessing — county lines above all, and anywhere your phone may struggle with.
Look at the map for the ground included here. The car does not need to move to us. Our technicians work over every bit of that — roadside, forecourts, driveways, car parks.
Maney: stuck where you parked
The opportunity to pull in anywhere suitable doesn't come to everybody. If you noticed after setting off and ended up on the verge on Upper Holland Road, or in a lay-by somewhere with the hazard lights on, that's a routine call for us and not an unusual one.
Sit with your car while it's safe to wait inside, but out of the car when it is not. Every mile a diesel obliges you for on petrol draws the mix further into the fuel system — and oblige it often will, which is why the engine does not get restarted to limp somewhere handier. Carrying on does your car far more harm than our van heading out to an inconvenient spot, and that is no trouble for us.
Already run it? Petrol in a diesel over some miles
The M6 Toll is the road which counts here, and sits under 3 miles from Maney. It will often take you onto it, and some way along, before you spot a thing. Then it's smoke, a lumpy idle and power falling away — not a clean stop. Wrongly fuelled diesels rarely give you one of those.
The first safe junction is the one to take. Turn off there, and leave the restarting alone. Suppose the worst of that on a long trip. Anything close to the under 10 miles to the nearest city, and the mixture has been through your filter, through the pump, through your injectors. Tell us when you call. What our engineers bring differs.
All about Maney
Maney is a suburban area in the West Midlands, situated near the River Tame and close to the city of Birmingham. Maney has a mix of housing types, but semi-detached homes are particularly prevalent in the area. Maney sits at an elevation of around 110 metres, with nearby Royal Sutton Coldfield and Sutton Coldfield providing local amenities. Maney is located approximately 6.6 miles from Birmingham city centre, making it a commuter-friendly location.
What comes next when our engineers reach you in Maney
- The answers change the work, which is why our engineers ask before quoting: what got in, how much of it, and whether the engine has run.
- Our technicians drain that tank of the tainted fuel.
- We rinse your fuel lines and clean the fuel filter, so what's remaining in your system is not what started the problem.
- New diesel goes in, and then the system gets primed.
- The motor is fired up and tested to make sure it runs properly on new diesel.
That has the car ready to drive away. There's no need to go to a garage at any stage, because the work is all done where your car is, and when it's caught soon, permanent damage is very unusual.
A different job: AdBlue in a diesel tank around Maney
The problem isn't the same, though the opening instruction is — don't start it — if what was put in was AdBlue instead of petrol. The lubrication a fuel system relies on gets stripped away by petrol, which dilutes the diesel. Urea dissolved in water, AdBlue, and in a diesel tank that causes rust and residue.
Usually the more serious of the two, AdBlue — and the details sits on its own Maney page. Both are ours to handle.
Maney pricing for a petrol-in-diesel fuel drain
What moves the price is listed below, as this job is not one job and our technicians can't honestly put a single figure on this page.
- Started? Driven? Either answer counts more than anything else on this list.
- How much of the wrong fuel got in, compared with how much that tank takes.
- AdBlue or petrol, whichever got in.
- Access: the vehicle's position, and whether working on it there is sensible for our van.
The car, the amount, whether it has run — give us those and the answer comes back firm instead of as a range. Not pressing, with the car at home and going nowhere? Then is fine.
Questions our technicians get about petrol in diesel in Maney
Fuel drains on a Maney petrol station forecourt
Plenty of what our engineers do gets done nowhere else. So yes. Routinely, provided the site consents: Esso, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that location is something our technicians answer straight away.
How much petrol in a diesel is too much?
Proportion decides it instead of litres — and more than either, whether your motor has run. A nearly empty tank with five litres in it, against a full one with the same five: different situations, definitely. Either way, the work needed comes down to one thing, which is if the fuel system has had that mix pulled through it.
I put petrol in my diesel and drove it. What next?
Stop somewhere sensible, switch off, and keep the car off. Driving is what takes the problem from the tank into the pump and injectors — but it is fixable a lot more regularly than people assume, and the single most useful thing you can do now is not restart the car.
Will a fuel drain void my warranty?
No. Carried out correctly, clearing and flushing is no change at all, and the warranty from your manufacturer is untouched by it. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Two-stroke oil in that tank, and then home?
Two-stroke oil solves a different fault, 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.
A main dealer for petrol in a diesel — needed?
No. Our engineers drain and clean the vehicle wherever it is, so there's no need to bring it to a main dealer.
Standing next to it?
Switched off is the way it remains.
Driven it already? Then somewhere safe, stop, switch off, and no restarting the vehicle after that. A still, cold vehicle is the best position to be in, and this is recoverable from far more often than people expect.
