Riverside: Put Petrol in a Diesel Car?
With your tank still carrying the fuel and your engine not yet run, nearly every job requires only a drain, so keep the engine off. That result is determined in the minutes right after the fill-up, rather than by the amount that went in. All over Riverside and the remainder of Somerset, Petrol in Diesel drains your car and cleans it where it is, whether at a roadside, on a drive or at a forecourt. Call us before anything else begins, and you will see what comes from there.
Petrol in a diesel: what to try next
- Whenever you drive, the pump and the injectors suffer. That's why you do not crank it, and why you do not trust it once it has started. The trick about petrol in a diesel especially — the part most people get wrong — is that it drives away happily for the first mile or two. Diesel in a petrol engine typically cannot run at all, which stops the person and stops the damage with them. This one lets you drive on.
- Diesel ignites, and before it burns it lubricates — your injection pump, its injectors. Petrol manages only the burning. So leave your ignition be as well: turning it on is often all it takes to prime that system, and priming moves petrol from your tank into just those parts.
- Never add diesel on top to dilute it. A diesel fuel system does not tolerate petrol by percentage in the way that advice suggests, and topping up clears nothing — it simply hands you a bigger tank of the same blend. The grade makes no difference either: super unleaded is just petrol.
- Remain where you are if you safely can. A car that hasn't shifted is the simplest one to handle, and we would much rather drive to an awkward spot than have it started. If you are parked on the verge on Chilcompton Road, switch the hazards on and leave the vehicle there.
- Keep your whereabouts prepared before you call. A postcode starting BA3 2 and whatever is closest to you with a sign on it is the difference between the van arriving and a van circling.
- What went in, approximately how many litres, and if your car has fired — those three replies shape the full call-out. Dial 0333 366 0103 and tell us.
Tonight, please, not Monday. Running it home is the one thing not to do: a commute has pushed real quantity through the pump already, petrol-thinned diesel and plenty of that, and the return leg would more or less double the figure to no purpose. The Volkswagen Tiguan can stay at Oldfield Park perfectly safely. Ring from the platform if simpler; standing over us whilst our engineers work is not required.
The complicated part is the bay, not the fuel. Cars either side of you, a trolley shelter behind, and from time to time a height limit on the way in that decides if a technician can get to you at all — so when you call from a car park like the one outside Sainsbury's, tell us how much space there is about you and which way round the car is. Those our technicians cover frequently. Should there be no room to work alongside the diesel Skoda Octavia, it gets moved with the motor off, and not out of pedantry over a handful of seconds of running: priming occurs at every start, more of that blend leaves that tank for your pump, and two shunts into a nicer bay have gradually made a harder job of what was merely a vehicle standing still.
Twenty to nine. At the gates of Longvernal Primary School. Late already, and the receipt in your hand shows unleaded. Turn the hazard lights on, leave the motor alone, and phone us. You could think three miles is nothing, in your Audi A4 or anything else — except that fuel is supplied on demand, and a run taken in a hurry needs a great deal of that.
A car you collected two days ago gets driven further before anybody spots anything, which is the hire and courtesy issue in one sentence — and how far it went is what determines the amount of petrol getting to the injectors. Nothing careless about the mistake itself: a modern diesel filler neck accepts the narrower petrol nozzle with practically no resistance, and so unfamiliar locations see most of these. Ring us from wherever you are, near St John the Baptist or not, and we will get to the Vauxhall Insignia.
By this point that tank is not where most of the damage is. Once a diesel has run, the blend is in your filter, your lines, your pump and its rail — and it doesn't come back out with the tank contents. A diesel Citroen C4 that got near Midsomer Norton Children's Centre needs your circuit flushed, not drained.
Forecourt draining for petrol in a diesel
Forecourts are where this job usually begins, and where a large part of it closes. The drain normally happens there and then. Still on the forecourt at Esso? Given the owner's permission, that's a spot our engineers work, and regularly.
No place except the forecourt can the mistake be halted with the motor still unrun. Fuel drawn out of your tank and through the filter, right to your high-pressure pump, is what occurs when the motor is started and the vehicle is moved to where it is now: the car park, the driveway or the lay-by, everywhere other than the forecourt. So the flush takes in the filter and the fuel lines along with that tank. That is still not a catastrophe, and we deal with it where the vehicle is. What determines it is whether the ignition was reached for in the seconds after the till receipt was read.
Staff will generally chip in pushing it away from the pump, which lets the next driver get past. Accept the help. Firing it just to roll four vehicle lengths isn't.
Will our engineers reach your part of Riverside?
These same trips get us to Hillside, Providence Place, Midsomer Norton, Hayes Park and Norton Hill besides Riverside, which is a residential suburb.
Our technicians do come. Those names above are only the immediate neighbours, and a page exists for most locations around Somerset, so an absence from the list isn't an absence from the coverage. Call us and ask instead of presuming — boundaries especially, and wherever your satnav may get wrong.
See this map for the ground covered on this page. Roadside, forecourt, private drive, car park: the lot is territory our technicians cover, and none of that asks your vehicle to move to us.
Riverside: broken down wherever you parked
Some people have no sensible spot to pull in at all. Hazards flashing at a lay-by somewhere, or stopped on the verge on Redlands Terrace since you realised after setting off — we take that call so often that it is the usual kind.
Out of the car if it's not wise to wait there, beside it if it is. It will often oblige. A diesel running on petrol limps along perfectly willingly, and that is the trouble: fire it up to reach somewhere better and the mix goes further into the system with every mile travelled. A van coming to a tricky place is no problem for us, and it is much better for your car than carrying on.
So you've run it? Petrol in a diesel over a few miles
under 15 miles out of Riverside, the local M32 is what counts now. A loss of power, a rough idle, smoke: those are the signs when they appear, instead of a clean stop — and a misfilled diesel will frequently take you onto it and some way along before anything seems wrong at all.
The first sensible exit is the one to take. Turn off there, and leave the restarting alone. It changes what our technicians bring, and so tell us when you phone: on a longer trip — anything approaching the under 10 miles to the nearest city — assume the petrol has been through the fuel filter, your pump and your injectors.
A bit about Riverside
Riverside is a suburban area in Somerset, situated on the banks of a river at an elevation of around 104 metres. Riverside lies near the city of Wells and other nearby places such as Hillside and Midsomer Norton, forming part of the wider South West region. Riverside has a population of approximately 3696 people and predominantly consists of semi-detached housing.
The job in Riverside, step by step
- Three things get asked before any quote — the fuel that got in, the amount, and if anything has been run since. Each answer shapes the work.
- Out comes the contaminated fuel.
- What is left in your system shouldn't be what started the problem, and so your fuel lines get rinsed and your filter cleared.
- Our technicians pour clean diesel in and prime your system.
- It's fired up with new diesel in it, and our engineers check that it's running smoothly.
At that point it's ready to drive away. Our technicians do all of this wherever the car has ended up, which means it never has to go to a garage, and if it has been caught quickly, it's very uncommon for there to be long-term damage.
AdBlue in your diesel tank by mistake, in Riverside?
The fault isn't the same, though the first instruction is — never start it — if what got in was AdBlue rather than petrol. Petrol does two things to diesel: thins it, and takes away the protection your fuel system depends on. Urea in water, AdBlue, and in a diesel tank that leads to corrosion and build-up.
Both are ours. There's a separate Riverside page for AdBlue removal, with the details on it — including the reasons it often turns out to be the worse of the two.
What a petrol-in-diesel drain will cost in Riverside
What shifts the price is laid out below, because the job is not one job and we can't honestly put a single price on this page.
- Has it been run or driven? Nothing else matters for as much.
- How much of the wrong fuel was put in, against how much that tank holds.
- AdBlue or unleaded, whichever was put in.
- Where your vehicle is, and whether our van can safely get to and work on it.
Tell us what the car is, how much went in, and whether your motor has run. A clear answer comes back, not a range. For the vehicle at home that's going nowhere and isn't time-critical, works too.
Petrol in diesel queries from Riverside drivers
At a petrol station in Riverside, can you do a fuel drain there?
Yes, and it's where a large portion of this work gets done. Permission from the site is the condition. Given that, a forecourt like Tesco is somewhere we're regularly, along with the rest of them locally — so name yours on the call and you will hear if working there's possible.
Is there a sensible amount of petrol in a diesel?
It depends on the proportion rather than the litres, and far more on whether the engine has run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same query in the end: has that mixture been pulled right through, or has it not?
I put petrol in my diesel and drove it. What now?
Pull in somewhere safe, switch off, then leave it off. Not restarting it is the single most helpful thing available to you now. Driving does shift the problem out of that tank and into the pump and injectors, yes, and it remains salvageable much more frequently than motorists fear.
Fuel drains and manufacturer warranties
No. Carried out properly, draining and purging is no modification at all, and the warranty from your manufacturer is unaffected by it. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave it switched off.
Can I just add two-stroke oil and drive home?
No. It belongs to a different problem from a different era, and petrol has diluted something no oil of that kind puts back. Your pump still has to cope with it, since that tank still has petrol in it later.
Does petrol in a diesel have to go to a main dealer?
You don't need one. The car is drained and cleaned wherever it is, with no need to take it to a dealership.
Still with the vehicle?
Keep the engine switched off.
Already driven it? Then pull over somewhere sensible, switch off, then let the car remain that way. Cold, still, going nowhere: that's the best position to be in. People fear this much more than they need to.
