Put Petrol in a Diesel Car in Westwood?
If you have not fired up the engine yet, do not. A drain and nothing more is nearly always what a vehicle needs while the fuel is still inside that tank and the engine has not yet been started, 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 Westwood or the rest of Devon, on the forecourt, at the roadside or on a drive, and drains and flushes it there. Ring us before everything else starts, and you will see what happens next.
Petrol in a diesel: what to do next
- Feed a petrol motor diesel and it will typically not run at all, and so the motorist stops there and so does the damage. Give a diesel petrol and the car starts, it idles, it moves off — all right for a couple of miles. Drivers have that muddled, which is the thing they get wrong about petrol in a diesel specifically. So never crank it. And once started, never depend on it: that fuel system is grinding while you drive.
- Two things, diesel: it burns, and on the way through it keeps that high-pressure pump and injectors protected. Petrol only does the one. Which is why your ignition stays off also — switch it on and you usually prime that system, and that is petrol exiting your tank for exactly those parts.
- Don't thin it. Diesel added on top gets rid of nothing, so all you get is more of what was already there, since percentage isn't how a diesel fuel system handles petrol. Super unleaded? Simply petrol. The octane makes no difference.
- Our team would much rather get to an odd location than have it started — so if you reasonably can, sit tight. Nothing is simpler to sort out than a vehicle that hasn't moved. On the verge on Westwood Road, that means hazards on and leave the car.
- Find out where you are before calling. A postcode starting EX17 3, and the name of whatever is closest to you. Otherwise the van circles rather than showing up.
- Call 0333 366 0103. Tell us what was put in, roughly how many litres, and if the engine has run. Those three details shape your whole job.
Removing petrol from the diesel on a forecourt
Pumps are where this job usually kicks off, and where a large part of it finishes. Still at Shell? Then that is normally where it happens. Petrol station forecourts are routine for us, with the permission of the owner.
Before your motor has run — a garage is the only place this is caught. Fuel drawn out of your tank and through the fuel filter, right to the high-pressure pump, is what occurs when the motor is switched on and your car is driven to where it is now: the car park, the private drive or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and the lines as well as your tank. That is still not a calamity, and our technicians sort it out where the car stands. What decides it is whether the ignition was reached for in the seconds after the receipt was checked.
Away from the pump, the next customer can get through — so yes, let the staff help you push the car. Very much worth it. Rolling the car four spaces doesn't merit firing the motor.
The complicated part is the bay, not the fuel. Vehicles either side of you, a trolley shelter behind, and now and then a height barrier on the way in that settles if our van can reach you at all — so when you ring from a car park like the one at Morrisons, mention how much clearance there's about you and which way round the car is. Those our engineers visit regularly. Should there be no room to work next to your diesel Audi A4, it gets moved with your engine off, and not out of pedantry over a handful of seconds of running: priming takes place at every start, more of that blend leaves that tank for your pump, and two shunts into a nicer bay have quietly made a harder job of what was simply a car sitting still.
Twenty to nine outside Landscore Primary School, already late, and the receipt in your hand reads unleaded. Hazards on, engine off, call us. Three miles in the Ford Focus feels like nothing, but a diesel pump delivers fuel on demand — while a rushed morning drive needs plenty.
Diesel has to be heavy enough to seal the precision components it flows through, and petrol dilutes it. That's the full mechanism, and it explains the ordinary the green space at the edge of the village call: a diesel BMW 1 Series that travelled out there without a murmur and came back down on power, lumpy at idle, possibly smoking a little. A diesel injection system works hydraulically as well as chemically — it needs your fuel to hold pressure, not just to burn — so when your fuel dilutes, pressure that should build then stay built starts bleeding past clearances instead, and your engine gets a poorer, later, less even delivery than it was engineered around. None of that is your engine failing, which is the bit worth hearing: it's the fuel no longer acting like diesel, and it stops when your fuel is put right.
Hardly ever the problem, the place. On-street is the most common spot our engineers work, and a cramped parking space is far preferable to a motor that has been driven somewhere more handy. What does help, when you ring from near Old Landscore School, is three things: the side the filler is on, whether a technician can pull up alongside without blocking the road, and whether anything has run since you filled up. Then your Vauxhall Astra gets emptied, the fuel filter changed where a workable one exists, the fuel lines cleaned and fresh fuel put through the entire circuit — since by now the worst of it is in your lines, not the tank.
The slimmer petrol nozzle goes into a newer diesel filler neck with almost no resistance at all, which makes this mechanical instead of careless. New spots see most of that for that reason. So: filled up near St Lawrence Chapel without thinking, in a diesel Mercedes A-Class you have had for two days? Ring us where you are. Hire and courtesy cars usually get driven further before anyone realises, and distance determines how much petrol gets to your injectors.
Parts our vans cover in Westwood
Westwood is a residential suburb, and so our vans head out to it and to the areas by it on the usual runs: West Town, Crediton, Salmonhutch, East Town and Uton.
If yours is not on this list that does not mean we don't come — there are separate pages for nearly all places in Devon, and the ones listed above are just the immediate neighbours. Presuming is the habit to skip, especially on the boundary or somewhere a satnav goes wrong. Call us and check.
The ground this page spans is on this map. The vehicle never needs to travel to us. We work throughout the lot — kerbside, forecourts, driveways, car parks.
Kerbside breakdowns around Westwood
The chance to pull over somewhere suitable does not fall to everyone. If you realised after setting off and ended up by the verge beside Tuckers Meadow, or in a lay-by somewhere with your hazards flashing, that is a normal call for us rather than an unusual one.
Remain by the motor when it is sensible to sit there, and clear of the vehicle when it is not. Never start up the motor to nurse it somewhere handier — a diesel running on petrol will often oblige, and every mile it obliges for is drawing that blend further into your fuel system. A van heading to an inconvenient spot is no problem for us, and it is much better for your car than driving on.
So you've driven it? Petrol in a diesel over a few miles
This is where the local M5 comes into it — under 10 miles away from Westwood. It will frequently take you onto it, and some way along, before you feel a thing. Then it is smoke, a rough idle and power falling away — not a neat stop. Misfuelled diesels rarely give you one of those.
Don't restart it to move it. Come off at the first sensible exit and switch off. On a longer run — anything near the under 10 miles to the nearest city — assume the contamination has been through your filter, the pump and the fuel injectors, and mention it when you call. It affects what we bring.
Where's Westwood?
Westwood is a suburban area in Devon, situated inland at an elevation of 66 metres, approximately 7.6 miles from Exeter. Westwood has a population of around 2306 people and is characterised by predominantly detached housing. Westwood is located near other small settlements such as West Town and Crediton, and is part of the wider Exeter urban area. Westwood sits in a region of gentle hills and valleys, typical of the South West of England.
What follows when our technicians get to you in Westwood
- Our technicians establish what was put in, how much, and if your engine has run. The responses change the work, which is why our engineers ask before pricing.
- Away goes the tainted mixture.
- Our engineers flush your fuel lines and clear the filter, and so what's left in the fuel system is not what caused the problem.
- Clean diesel goes in, and then the fuel system gets primed.
- After it's started, our technicians make sure it runs properly on new diesel.
From there, you're ready to pull away. Lasting damage is very rare when it has been caught quickly, and since all of it is done where the car is, it never needs to be taken to a workshop.
AdBlue in your diesel tank instead, around Westwood?
The problem isn't the same, though the first rule is — don't crank it — if what was put in was AdBlue rather than petrol. The protection a fuel system relies on gets taken away by petrol, which thins your diesel. Urea in water, AdBlue, and in a diesel tank that causes rust and residue.
Often the more serious of the two, AdBlue — and the details lives on its own Westwood page. Both are ours to deal with.
How much is a petrol-in-diesel drain around Westwood?
Honestly, no single figure fits on a page like this. The job changes. Here's what changes it:
- Whether the engine has been run or driven. This is the big one.
- Wrong fuel in, against what your tank takes — that proportion.
- Whether it was petrol or AdBlue.
- Where is it? And can our van get to it and work there sensibly?
The vehicle, the amount, whether it has run — give us those and the answer comes back firm rather than as a range. For the car at home that is going nowhere and is not time-critical, is fine too.
Westwood drivers ask us these about petrol in diesel
At a petrol station around Westwood, can you do a fuel drain there?
Much of what our engineers do gets done nowhere else. So yes. Our engineers work at Tesco and the other forecourts locally regularly, with the site's agreement — tell us which one you're at when you phone and we'll tell you whether our engineers can work there.
How much petrol is too much for a diesel?
Whether your engine has run counts much more, though the ratio matters too, rather than the litres. Five litres into an almost dry tank is not five into a full one, no. But both land on the same question in the end: has that mixture been drawn right through, or has it not?
I put petrol in my diesel and drove it. What next?
Pull over somewhere sensible, switch off, and leave the vehicle off. It is salvageable a lot more often than motorists expect, even though driving is what moves the problem from your tank into the pump and injectors — and the single most valuable thing you can do now isn't restart it.
Will a fuel drain void my warranty?
A manufacturer's warranty outlasts a drain then flush done to a correct standard, which is no modification at all. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Two-stroke oil in that tank, and then home?
What petrol has diluted is not replaced by two-stroke oil, which is an old workaround for a different fault. So no. The pump still has to live with it, because that tank still has petrol in it later.
A main dealer for petrol in a diesel — needed?
Wherever the vehicle is, our technicians drain and flush it there, so a visit to the main dealer does not come into it.
You, and the vehicle, still together?
Shut off is the way the car stays.
Already driven it? Then stop somewhere safe, switch off, and let the vehicle stay that way. A parked, cold vehicle is the best position to be in, and this is recoverable from far more commonly than motorists assume.
