Tinhay: Put Petrol in a Diesel Car?
If you have not turned on your engine as yet, do not. A drain and nothing else is almost always what a vehicle needs while the fuel is still inside that tank and the engine has not turned over, which is why it is the next few minutes that count, not how much got in. Petrol in Diesel goes to the vehicle wherever it has ended up in Tinhay or the remainder of Devon, on the forecourt, by the roadside or on a driveway, and drains and cleans it there. One ring our way will be plenty: our team will tell you what follows from here. Make that straight away.
What to try next about petrol in a diesel
- Don't fire it up — and do not depend on it if it starts. This is the thing most people have wrong about petrol in a diesel especially. A petrol motor filled with diesel normally just can't run, and so the driver stops and the harm halts with them. A diesel fed petrol normally starts, ticks over and drives away just fine for several miles. It's not okay. It is eating into your fuel system while you drive.
- Diesel ignites, and before it combusts it lubricates — your high-pressure pump, those injectors. Petrol handles only the burning. So leave your ignition off too: switching it on is commonly all it takes to prime your system, and priming pulls petrol from your tank into exactly those parts.
- That advice assumes a diesel fuel system tolerates petrol by percentage. It won't. Put diesel on top and nothing at all is removed; what you end with is a bigger tank of the same mix. And no, the octane makes no difference — super unleaded is still petrol.
- Remain where you are if you reasonably can. A motor that hasn't shifted is the easiest one to handle, and our team would rather get to a tricky location than have it started. If you're stopped on the verge on Station Road, put your hazards on and keep it there.
- Find out where you are before ringing. A postcode that starts PL16 0, and the name of whatever is closest to you. Otherwise the technician circles rather than arriving.
- Ring 0333 366 0103. Let us know what was put in, roughly how much, and also if the engine has started. These three details determine the full job.
Your high-pressure pump spent that morning commute labouring on a fuel that had given up most of the protection it is built around. Diesel lubricates that pump, and your injectors with it, before any of the fuel burns; petrol does the burning and none of the oiling. So imagine a diesel Volkswagen Passat, topped up at quarter past eight, taken in to work, and left sitting at Gunnislake until the penny drops at about eleven. Three hours of sitting have altered nothing about it. The couple of miles before that did plenty, which is why the question we ask you is about miles instead of time. Call us. Leave it right where it is.
Put diesel in a petrol vehicle and usually it will not run, so the motorist stops there and the damage stops with them. Flip it — petrol into a diesel — and the thing starts, idles and drives off as though nothing had happened, whilst your high-pressure pump works without the protection your fuel is meant to be providing. That is the snag, and it is why your diesel Nissan Qashqai will have felt completely ordinary coming back from Lifton Community Academy. They do. From behind the wheel there's nothing to alert you about, so nothing warns you. Phone with roughly how far you travelled, and how hard; the second answer counts more than the first.
Straightforward job, this one — until somebody takes it home. A diesel Mercedes E-Class sitting at the pub in the village with petrol in that tank loses nothing by standing there overnight, so park the vehicle then phone us once it's light. Expect a query about that run there, though. Short and cold is precisely where petrol battles to burn, and what won't burn can slip past the rings then into the oil.
Leave the Ford Kuga close to St Mary the Virgin and phone us. We are direct about not driving on as a worn pump gives off, and what it loses travels on with your fuel to the fuel injectors further along.
Petrol in a diesel does its harm as a ratio, which is the reason we ask at all: the same few litres sitting in an almost empty tank make a far stronger blend than they would in a full one. And petrol is rated on how well it resists igniting under pressure — the opposite of what a diesel wants — so a stronger blend rattles more, smokes more, goes flatter. None of which means you need an answer prepared. Nearly nobody knows how full the tank was in a motor collected two days ago, and our technicians work that out there. Do ring the hire or company firm first, though: some contracts want them to authorise the work, and that is far faster settled before than after. Then call us about the Skoda Superb close to Lifton Community Centre.
Can petrol be pumped from your diesel at the forecourt?
The job starts at the pump, generally. Often enough the work finishes on site too. If you are still at the forecourt at Tesco, that's generally where this drain happens — we operate on petrol station forecourts regularly, with the owner's consent.
Nowhere except the forecourt can it be stopped with the engine still cold. We can still put it right where it is, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been fired up and moved there, and that pulled fuel through the filter then into the high-pressure pump, right from your tank. None of that is a catastrophe, although the flush then has to go past that tank to your lines and your filter, and the few seconds between checking your receipt and going for the keys are what decide that.
Attendants will generally chip in pushing it out from the pump, which lets the next customer get by. Accept the offer. Shifting the car four spaces does not justify firing it.
Service in Tinhay
The same runs carry us to Lifton, Sprytown, Portgate, Liftondown and Gatherley along with Tinhay, which is a village.
There are separate pages for most towns around Devon, and the ones listed above are just the immediate neighbours — so yours being missing from that list says nothing whatsoever about if our engineers come. Assuming is the habit to resist, especially on the border or somewhere a satnav gets lost. Call us and ask.
The area the page includes is on the map. We work by the road, at forecourts, on driveways and at car parks across all of that, and the vehicle doesn't need to move to us.
Stuck on the roadside around Tinhay
A chance to pull over somewhere sensible doesn't fall to everybody. If you realised after setting off and landed along the verge beside Old Tinhay, or in a lay-by somewhere with the hazard lights on, that's a common call for us instead of an odd one.
Remain with your car when it's safe to sit there, and out of the vehicle when it is not. Don't start it up to get to a nicer location. It will go — a diesel on petrol normally obliges — and each mile of obliging pulls the blend deeper into the system. Carrying on causes the car far more harm than our van coming out to a tricky spot, and that is no problem for us.
A few miles on petrol in a diesel: what next?
Here is where the M5 comes into it — under 50 miles from Tinhay. It will frequently get you onto it, and some way along, before you feel a thing. Then it's smoke, a lumpy idle and power draining away — not a tidy 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. It affects what our technicians bring, and so say so when you phone: on a longer drive — anything near the under 25 miles to the closest city — take it the contamination has been through your filter, your pump and your injectors.
Tinhay itself
Tinhay is a small village in Devon, situated on the riverside at an elevation of around 60 metres. Tinhay lies near the villages of Lifton and Sprytown, and is close to the hamlet of Portgate. Tinhay has a population of approximately 502 people, predominantly living in detached houses. Tinhay is located near the city of Plymouth, which is 19.7 miles away.
When our engineers get to you in Tinhay: what follows
- The responses shape the work, which is why our technicians ask before quoting: what went in, how much of it, and if the engine has run.
- The polluted fuel is drawn from the tank.
- What is remaining in the system should not be what started the problem, so the fuel lines get cleaned and your filter cleared.
- Our engineers pour clean diesel in and prime the system.
- The motor is started and checked to confirm it runs smoothly on clean diesel.
That has it ready to pull away. All of this is done where the vehicle is, so it never needs to be taken to a garage, and when it has been spotted early, permanent damage is very unusual.
Tinhay AdBlue removal is a different problem
AdBlue rather than petrol? Then the opening step is unchanged — your motor stays off — whereas this problem under it is a distinct one altogether. Diluted diesel, and no lubrication left for the fuel system that relies on it. That's petrol. AdBlue is urea in water, and in a diesel tank it leads to rust and deposits instead.
AdBlue removal around Tinhay has a page of its own with the details on it, including why it's frequently the more serious of the two. We cover both.
What a petrol-in-diesel drain will cost around Tinhay
One price wouldn't be honest here, since this is not one job. These are the things that change it:
- Has it been run or driven? Nothing else matters for as much.
- How much of the wrong fuel went in, measured against how much the tank can hold.
- AdBlue or unleaded, whichever went in.
- Access: the vehicle's position, and if working on it there is safe for a van.
The car, the quantity, whether it has run — give us those and the answer comes back straight rather than as a range. If it is not pressing — your car is at home and going nowhere — is fine too.
Tinhay drivers ask us these about petrol in diesel
At a petrol station in Tinhay, can you do a fuel drain there?
Yes, and it's where a large share of this work happens. Our technicians attend BP and the other forecourts around town routinely, with the owner's consent — tell us which one you're at when you phone and we'll tell you whether our engineers can work there.
A few litres of petrol in a diesel — too much?
Proportion decides it rather than litres — and more than either, whether the motor has run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that blend been drawn right through, or has it not?
Petrol in my diesel, and I have driven the vehicle
Somewhere sensible, then stop, then switch off and leave it off. Driving moves 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 truly valuable thing left to you isn't restarting the vehicle.
My warranty — does a fuel drain void it?
No. Carried out properly, draining and flushing is no modification at all, and the warranty from your manufacturer is untouched by it. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Can I just add two-stroke oil and drive home?
No. It belongs to a distinct fault from a bygone era, and petrol has diluted something no oil of that kind replaces. Your pump still has to live with it, because the tank still has petrol in it afterwards.
Does petrol in a diesel have to go to a main dealer?
Not at all. Our engineers drain and flush the car wherever it is, so there's no need to bring it to a main dealer.
Is the vehicle still with you?
Leave the engine switched off.
Driven it already? Then somewhere sensible, stop, switch off, and no restarting the car later. This is recoverable from far more regularly than drivers fear, and a stationary, cold car is the best place to be in.
