Put Petrol in a Diesel Car in Millway Rise?
With your tank still holding the petrol and the motor not yet run, almost every job takes only a drain, so keep the engine off. That outcome is determined in the minutes right after filling up, rather than by the amount that got in. All over Millway Rise and the remainder of Devon, Petrol in Diesel drains your car and cleans it where it is, whether at a roadside, on a private drive or at a forecourt. Contact us and our engineers will explain what happens after that before you try any more.
What to do first about petrol in a diesel
- Feed a petrol engine diesel and it will normally fail to run at all, and so the person stops there and so does the damage. Give a diesel petrol and the engine starts, it ticks over, it drives off — all right for a couple of miles. Drivers have that backwards, which is the bit they get wrong about petrol in a diesel especially. So do not crank it. And once started, don't trust it: that fuel system is wearing while you drive.
- Two jobs, diesel: it ignites, and on the way through it keeps your injection pump and injectors lubricated. Petrol only manages the one. Which is why the ignition is left off too — switch it on and you frequently prime your system, and that is petrol exiting the tank for precisely those components.
- Topping up clears nothing. It leaves you a larger tank of the same mixture, since a diesel fuel system will not handle petrol by percentage the way that advice implies — so do not tip diesel on top to dilute it. Octane is beside the point too: super unleaded is petrol.
- A vehicle that hasn't shifted is the easiest one to sort, so stay where you are if you safely can. Pulled up on the verge on Chard Road? Hazards on, then leave it there. An odd location works for us better than a started engine.
- Keep your location ready before you call. A postcode that starts EX13 5 and whatever is next to you with a sign on it is the difference between a van showing up and the van circling.
- Phone 0333 366 0103. Prepare for three queries — what was put in, roughly how much, and whether the car has been started. Those answers determine whatever comes after.
Clearing petrol from a diesel on the forecourt
Forecourts are where the work mostly kicks off, and where a large chunk of it ends. The drain typically takes place there and then. Still on the forecourt at Harvest Energy? Given the owner's consent, that's a place our technicians work, and routinely.
A forecourt is the only spot it gets caught before the motor has fired. Anywhere else — a car park, a drive, a lay-by — the car was started and driven to get there, which means fuel was pulled from your tank, through the fuel filter and into the high-pressure pump. That is not a disaster, and our technicians can still put it right where it sits. It does mean your lines and the fuel filter need flushing as well as your tank, and that is settled by the few seconds between reading the receipt and going for the keys.
Roll the vehicle out of the way if the staff volunteer, and they generally will. The next motorist gets through the pump, and that's worth doing. Cranking it to move four car lengths isn't.
Car parks like the one outside Co-op Food are a place we work in often, and the fuel is hardly ever the complicated part. The bay is: vehicles either side, a trolley shelter behind, at times a height barrier on the way in that decides whether a technician can access you at all. So tell us how penned in you are when you call, and which way the car is facing. When our technicians cannot work alongside your diesel Skoda Octavia we will roll it without running it — and that's not fussiness about a couple of seconds of running. Every start primes the fuel system and pulls more of that mixture out of that tank and towards your pump, and so a motor moved twice into a better bay has gradually become a harder job than one left exactly where it stopped.
Your diesel BMW 3 Series will have seemed completely normal on the way back from Axminster Community Primary Academy. They do, and that is the trap with petrol in a diesel and not the other way round. Put diesel in a petrol motor and it generally won't run, so the person stops and the damage stops with them. Put petrol in a diesel and it starts, ticks over and drives off as though nothing has happened — all the while the high-pressure pump does its work without the lubrication the fuel is meant to be giving. Nothing alerts you, as from the driver's seat there's nothing to caution you about. Ring us with approximately how far you went and how hard you drove it; the second answer counts more than the first.
Risk the trip home from The Castle Inn? Not a chance. It will start and it will drive off just fine, which is the issue — a diesel on a thinned tank acts generally whilst wearing the components the fuel should be protecting. Park the Peugeot 308 and call us.
Out there normal, back flat. If that was the trip to Sector Wood, look at that tank. Diesel gets diluted by petrol, and thin fuel leaks past the fine gaps supposed to build injection pressure — so every additional mile the diesel Nissan Qashqai covered, the less pressure it held onto. Somewhere safe, turn off, ring us.
It got a few streets and stopped. The throttle went soft, the idle turned ragged, and the diesel Kia Sportage is now sitting near St Mary's Catholic Church. That softness is the fuel failing to build pressure fully not the motor packing up — and as there is no dashboard light for it, vehicles in that position typically get driven again before anybody phones. Do not. Switch it off then ring us.
Can we serve your part of Millway Rise?
Millway Rise is a small village, and so our team get out to the town and to the places near it on those same rounds: Weycroft, Axminster, Smallridge, Sector and All Saints.
Not on this list? That means nothing. The places above are only the closest few, and nearly all locations around Devon have a page of their own elsewhere on our site. Presuming is the mistake to avoid, particularly on the boundary or anywhere your satnav fails. Contact us and check.
The ground this page covers sits on our map. Your car does not need to travel to us. We work over all of that — kerbside, forecourts, driveways, car parks.
Kerbside call-outs across Millway Rise
Not everybody gets a sensible place to stop. If you realised after setting off and ended up by the verge on Millwey Court, or at a lay-by somewhere with your hazards going, that's a common call for us rather than a rare one.
Okay where you are? Wait with it. Not safe? Get out and away from it. Every mile a diesel obliges you for on petrol drags the mixture further into your fuel system — and oblige it frequently will, which is why the engine doesn't get restarted to limp somewhere better. Our van heading to an awkward location is no trouble for us, and it's far better for your car than carrying on.
Petrol in a diesel, and the motor has moved
Here is where the local M5 comes in, under 15 miles from Millway Rise. A wrongly fuelled diesel will often get you onto it and some way along before anything feels wrong, while the signs when they arrive are normally lost power, a lumpy idle and smoke instead of a tidy stop.
Pull off at the next safe exit, turn off, and don't restart the vehicle to reposition. On a longer trip — anything approaching the under 25 miles to the nearest city — take it the petrol has been through the fuel filter, the pump and your injectors, and mention it when you ring. It affects what our technicians bring.

Once we arrive with you in Millway Rise: what we do
- Our engineers ask first, quote after. What went in? How much? Has the motor run? Those replies change what the work really is.
- The tainted mixture is pulled out of your tank.
- Lines purged, filter cleared. Whatever remains after that isn't the thing that started the problem.
- Fresh diesel goes in, and then the fuel system gets primed.
- It is started with new diesel in it, and our technicians make sure that it's running smoothly.
Your car is then ready for you to drive away. We do everything wherever the vehicle has ended up, which means it never has to be taken to a garage, and if it has been noticed soon, it is very unusual for there to be permanent damage.
AdBlue in the diesel tank by mistake, around Millway Rise?
The fault isn't the same, though the opening instruction is — do not crank it — if what went in was AdBlue rather than petrol. Petrol does two things to diesel: dilutes it, and takes away the protection the system relies on. AdBlue is urea dissolved in water, and in a diesel tank it causes corrosion and residue instead.
Our engineers deal with both, and AdBlue removal in Millway Rise has its own page with the detail — including why it is often the more significant of the two.
What a petrol-in-diesel fuel drain will cost in Millway Rise
One price wouldn't be honest here, because this isn't one job. These are the things that change it:
- Whether your motor has been started or driven. This is the main one.
- How much of the wrong fuel went in, compared with how much your tank holds.
- Whether it's petrol or AdBlue.
- Where your car is, and if our van can safely get to and work on it.
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 isn't time-critical, is fine too.
Millway Rise motorists ask us these about petrol in diesel
Can you do a fuel drain at a petrol station around Millway Rise?
A big share of this work takes place there, so yes. Tell us which one you're at when you call and we will tell you if our technicians can work there. With the station's permission we work at Tesco and the other forecourts around town all the time.
Is there a safe amount of petrol in a diesel?
Whether your motor has run counts a lot more, though the ratio counts too, rather than the litres. Five litres in a nearly empty tank is a distinct case from five in a full one — but either way, the thing that settles how much work is needed is whether that mix has been drawn through the fuel system.
Already driven it with petrol in the diesel? What then?
Stop sensibly. Off. Nothing after that. Driving takes the problem 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 genuinely useful thing left to you is not restarting it.
Fuel drains and manufacturer warranties
A manufacturer's warranty outlasts a drain then flush done to a proper standard, which is no change at all. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Could I put some two-stroke in and just drive?
What petrol has diluted isn't restored by two-stroke oil, which is an old fix for a distinct problem. So no. Your pump still has to live with it, since the tank still has petrol in it later.
Main dealers and petrol in a diesel
You do not need one. The car is drained and cleaned wherever it is, with no need to take it to a dealership.
Waiting next to it?
Turned off is how it remains.
Driven it already? Then somewhere sensible, stop, turn off, and no restarting it later on. Cold, still, going nowhere: that's the best place to be in. People fear this much more than they need to.
