Put Petrol in a Diesel Car in Eachway? Don't Start It
Don't fire up your engine. While the petrol is still inside that tank and the engine has not yet run, a tank drain is nearly always all it requires — and that gets settled in the following few minutes, not by how much was put in. Petrol in Diesel drains and flushes wrong-fuelled cars where they sit, throughout Eachway and the rest of Worcestershire, on the forecourt, by the roadside or on a private drive. Just one call to us is plenty: we shall explain what follows from here. Make this straight away.
Petrol in a diesel: what to try first
- Feed a petrol engine diesel and it will usually refuse to run at all, so the driver stops there and so does the damage. Give a diesel petrol and the thing starts, it idles, it pulls away — all right for several miles. Motorists have that reversed, which is the thing they get wrong about petrol in a diesel specifically. So never start the car. And if started, do not depend on it: that fuel system is grinding while you drive.
- Diesel burns, and before it combusts it lubricates — your injection pump, its injectors. Petrol handles only the burning. So leave the ignition alone too: flicking it on is commonly enough to prime that system, and priming moves petrol from that tank into exactly those components.
- Topping up clears nothing. It hands you a larger tank of the same mix, because a diesel fuel system will not tolerate petrol by percentage the way that guidance implies — so never put diesel on top to dilute it. Octane is immaterial too: super unleaded is petrol.
- A motor that has never shifted is the easiest one to deal with, and so wait where you are if you safely can. Pulled up on the verge on Whitehouse Place? Hazards on, and keep the vehicle there. A difficult spot suits us better than a started engine.
- Before you call, have your position. Anything next to you with a sign on it, plus a postcode starting B45 9 — that's what determines whether our van shows up or circles.
- Dial 0333 366 0103. Anticipate three points — what was put in, roughly how many litres, and if the motor has been turned over. Your replies settle all that follows.
Quarter past eight, a hurried top-up on the road in, and the penny drops at about eleven — by then the diesel Renault Megane has been sitting at Longbridge for three hours. Phone us then keep the vehicle precisely where it is. The run in is the thing that matters most, since diesel performs two tasks on its way through the engine: it ignites, and before it ignites it lubricates that high-pressure fuel pump and the injectors. Petrol does the first and not the second. So those couple of miles were done with the pump labouring on a fuel that had shed much of the protection it is designed around — which is why the thing our technicians ask is how far you drove, not how long your vehicle has been stood.
Simple, these ones, and the reason is the miles: a mile at light throttle draws hardly any diesel. Petrol into a diesel BMW 3 Series somewhere in Eachway, a boot loaded with shopping, and you stranded outside Costcutter — call us. Leaving the space isn't worth a restart. The tank gets cleared where it waits, your fuel lines cleaned, clean diesel in, and you drive away.
It will fire up. It will move off quite happily. That's the issue, as a diesel on a weakened tank behaves normally while wearing the components its fuel should be lubricating. So no, do not try the journey home from The Toby Jug — leave the Citroen C3 then call us.
About as well as this goes, once your engine has turned: away from the pumps, receipt read, and your diesel Peugeot 2008 left close to The Beacon Church Centre hardly two streets on. Phone us, and leave the car off. A short hop does truly help. It was still a start and still a drive, though, so the filter and the pump have had weakened fuel through them — hence cleaning the lines instead of only clearing your tank.
Unfamiliar places are where this occurs most, and the reason is mechanical instead of sloppy: the smaller petrol nozzle goes into a modern diesel filler neck with practically no resistance at all. Filled up by The Toposcope without thinking, in a diesel Hyundai Tucson you have had for two days? Call us where you are. Hire and courtesy cars usually get driven further before anybody spots it, and miles is what settles how much petrol reaches the fuel injectors.
At a forecourt: removing petrol from a diesel
Plenty of the work begins at the pump, meaning a good chunk of it gets finished at one. The drain generally takes place right there. Still on the forecourt at Murco? Given the site's consent, that is somewhere our technicians work, and often.
The forecourt is the one place it can be spotted before the engine has started. Anywhere else — a car park, a private drive, a lay-by — your car was fired up and driven to get there, which means fuel was sucked from that tank, through the filter then into the high-pressure pump. That is not a calamity, and our technicians can still deal with it where it stands. It does mean the fuel lines and your filter need rinsing as well as that tank, and that is decided by the few seconds between reading the receipt and reaching for the key.
The attendants will normally happily wheel it away from the pump so the next motorist can get past. It is worth doing. Firing it just for four vehicle lengths? Not a chance.
Coverage in Eachway
Eachway is a small village, and so our team go out to it and to the villages near it on those same runs: Rubery, Lickey Hills, Lickey, Lydiate Ash and Rednal.
If yours isn't on that list that does not mean we don't come — there are separate pages for the majority of towns around Worcestershire, and the ones listed above are simply the closest neighbours. Phone and enquire instead of assuming, above all if you are on the boundary or somewhere a satnav can't find.
Check the map for the area shown on this page. Kerbside, forecourt, drive, car park: the lot is territory we cover, and none of that needs your car to move to us.
Eachway: stuck wherever you pulled up
Not everybody finds a safe place to stop. If you worked it out after setting off and landed on the verge of Shearwater Close, or at a lay-by somewhere with the hazard lights on, that is a routine call for us rather than an odd one.
Whether you stay beside your car or stand clear of it depends on if staying nearby seems wise. Do not restart it to reach a safer place. It'll go — a diesel on petrol generally obliges — and each mile of obliging draws the blend deeper into the system. We will send our van to an inconvenient spot without any trouble, and for the car that's much better than carrying on.
Petrol in a diesel, but the motor has rolled
This is where the M5 counts, under 3 miles from Eachway. A misfilled diesel will usually get you onto it and some distance along before anything seems wrong, and the symptoms when they appear are generally a drop in power, an uneven idle and some smoke rather than a neat stop.
The first sensible exit is the one to take. Switch off there, and leave the restarting alone. On a longer drive — anything near the under 10 miles to the closest city — take it the contamination has been through the fuel filter, your pump and your injectors, and say so when you call. It affects what we bring.
Where is Eachway?
Eachway is a locality in the West Midlands region of England, situated inland in Worcestershire at an elevation of 249 metres. Eachway lies approximately 8 miles west of Birmingham and is near the Lickey Hills, an area of woodland and heathland. Eachway has a population of around 862 people and is characterised by semi-detached housing. Eachway is also close to the nearby settlements of Rubery and Lickey.
What our technicians do when we reach you around Eachway
- Three things get checked before any price — the fuel that got in, the quantity, and if anything has been run since. Each answer changes the work.
- The tank gets cleared of everything.
- Fuel lines are flushed through and your filter cleared, leaving nothing in the fuel system that started any of this.
- Bleeding the system follows, once fresh diesel is in.
- When it is started, our engineers confirm it runs smoothly on new diesel.
Then it is ready to set off. All of this is done where the car is, so it never has to go to a garage, and when it has been noticed early, long-term damage is very uncommon.
Eachway AdBlue removal is a separate problem
The fault isn't the same, though the first instruction is — never start it — if what was put in was AdBlue instead of petrol. Petrol thins the diesel and removes the protection your fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it brings rust and deposits instead.
AdBlue removal around Eachway has a page of its own with the detail on it, including why it is frequently the more significant of the two. Our technicians cover both.
Paying for a petrol-in-diesel drain in Eachway
One number would not be honest here, because this isn't one job. These are the things that shift it:
- Has it been run or driven? Nothing else matters for as much.
- Wrong fuel in, against what your tank holds — that proportion.
- Which got in: petrol or AdBlue.
- Where is it? And can a van reach it and work there safely?
The car, the amount, whether it has run — give us those and the answer comes back firm rather than as a range. If it isn't time-critical — your car is at home and going nowhere — works too.
Petrol in diesel questions from Eachway motorists
Fuel drains on a Eachway petrol station forecourt
Yes, and it is where a fair share of this work gets done. Our technicians work at Morrisons and the other forecourts locally all the time, with the owner's permission — tell us which one you're at when you ring and we will tell you if our technicians can work there.
How much petrol is too much for a diesel?
Proportion decides it rather than litres — and more than either, whether the engine has run. Five litres in a nearly empty tank is a separate case from five in a full one — but either way, the thing that determines how much work is needed is whether that blend has been drawn through the fuel system.
Already driven it with petrol in your diesel? What then?
Somewhere sensible, then stop, then turn off and leave it off. Driving takes the issue along — out of that tank, into the pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting the vehicle.
My warranty — does a fuel drain void it?
A manufacturer's warranty outlasts a drain and flush done to a good standard, which is no alteration at all. What is likelier to start an argument is a diesel that has been run on petrol. One more good reason for the motor to stay off.
Can I just add two-stroke oil and drive home?
Two-stroke oil solves a distinct fault, and an old one at that. Nothing it does puts back what petrol diluted. No. Later on? Still petrol in your tank, and a pump that has to live with the stuff.
Do I need a main dealer for petrol in a diesel?
Wherever your car is, our engineers drain and flush it there, so a visit to the main dealer does not come into it.
You, and your vehicle, still together?
Do not turn it back on.
Already driven it? Then pull in somewhere sensible, turn off, and let the car stay that way. Cold, parked, going nowhere: that's the best position to be in. Drivers fear this a lot more than they need to.
