Ashton under Hill: Put Petrol in a Diesel Car?

With that tank still holding the fuel and the motor not yet run, almost every job needs only a drain, so leave the motor off. That outcome is determined in the minutes immediately after the fill-up, and not by the amount that was put in. Across Ashton under Hill and the rest of Worcestershire, Petrol in Diesel drains your car and cleans it where it stands, whether by a roadside, on a driveway or at a forecourt. Just one call our way is enough: our engineers will explain what follows next. Make this first.

The next five steps: petrol in a diesel

  • Do not start it. Started anyway? Then do not depend on it. Diesel in a petrol car normally cannot run, and so the person stops and the wear halts with them. Petrol in a diesel? It starts. It idles. It moves off normally, for a couple of miles. People get that reversed. It is not all right — the fuel system is wearing every mile you drive.
  • Two things, diesel: it ignites, and on the way through it keeps your high-pressure fuel pump and injectors lubricated. Petrol only manages the one. That is why your ignition remains off also — turn it on and you often prime the system, and that's petrol exiting that tank for just those components.
  • Never pour diesel on top to dilute it. A diesel fuel system doesn't accept petrol by percentage the way that guidance assumes, and topping up clears nothing — it only hands you a bigger tank of the same mix. The octane makes no difference either: super unleaded is just petrol.
  • Wait where you are if you safely can. A car that has never moved is the simplest one to handle, and we would rather come to an odd location than have it started. If you're pulled up on the verge on Cottons Lane, turn your hazards on then leave it there.
  • Before you ring, gather your position. Anything nearest to you with a sign on it, plus a postcode beginning WR11 7 — that is what settles whether the van turns up or circles.
  • Ring 0333 366 0103. Anticipate three queries — what got in, about how much, and if the engine has been turned over. Your responses settle all that follows.

Draining petrol from the diesel at the forecourt

Pumps are where this work mostly starts, and where a large chunk of that ends. If you're still at the forecourt at BP, that's normally where this drain gets done — our technicians work on station forecourts routinely, with the owner's consent.

Nowhere except the forecourt can it be halted with your motor still cold. Fuel pulled out of the tank and through the filter, all the way to the high-pressure fuel pump, is what happens when your engine is fired up and your car is moved to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush takes in the filter and the lines together with your tank. That is still not a disaster, and our engineers put it right where the car sits. What settles it is whether the key was turned in the seconds after the till receipt was read.

Staff will usually help out pushing it out from the petrol pump, which lets the next driver get past. Accept the help. Shifting the car four spaces doesn't warrant cranking the engine.

Parts our vans cover near Ashton under Hill

Ashton under Hill is a rural village, so our technicians go out to it and to the villages near it on those same trips: Grafton, Kersoe, Sedgeberrow, Dumbleton and Hinton on the Green.

If yours is not on this list it does not mean we don't come — there are pages for the majority of places across Worcestershire, and the ones named above are just the immediate neighbours. Close to the border, or somewhere the satnav struggles with? Call us to check rather than assuming.

The map outlines the area the page includes. The lot is territory our technicians serve: a kerbside, a forecourt, a driveway, a car park. You never move your car anywhere.

Nothing alerts you, because from behind the wheel there's nothing to be warned about. Your diesel Skoda Octavia will have felt perfectly normal on the way back from Ashton-under-Hill First School, and they all do — which is the trap with petrol in a diesel rather than the reverse. Diesel in a petrol motor generally refuses to run, stopping the motorist and stopping the harm with them. Petrol in a diesel starts, ticks over, moves off as though nothing had happened, and all the while the pump does its work without the protection its fuel is meant to supply. Tell us about how far, and how hard. The harder matters more.

What we'll ask about is if the trip there was short and chilly, since that is where petrol is slowest to burn correctly — and anything that won't burn can get past the rings then into the oil. Right up to the moment someone drives it home, a diesel Nissan Qashqai sitting in the car park at The Star Inn carrying a tank of petrol in it is a straightforward job. Nothing worsens while it stands, so park it overnight then phone us in the morning.

Don't drive it home to buy yourself time. You already have it: nothing gets worse whilst the vehicle stands, since a diesel BMW 5 Series left at Nap Coppice is doing none of what it did on the way there. Your pump has stopped turning.

A motor you collected two days ago gets driven further before anyone sees anything, which is the hire and courtesy fault in one sentence — and how far it went is what decides the quantity of petrol getting to the injectors. Nothing sloppy about the mistake itself: a current diesel filler neck takes the slimmer petrol nozzle with practically no resistance, so new spots see most of these. Phone us from wherever you are, close to Ashton Hall or not, and we will get to the Audi Q5.

By now the tank is the least of it. Run a diesel and that mix goes into the fuel filter, into your lines, into your pump, into its rail — and none of that leaves with that tank contents. A diesel Mercedes GLC that got close to War Memorial needs its system purged. Emptying is not the same thing.

Stuck on the kerbside somewhere around Ashton under Hill?

Not everybody gets a chance to stop anywhere sensible. If you noticed after setting off and ended up by the verge beside Elmley Road, or in a lay-by somewhere with your hazards on, that's a routine call for us instead of an unusual one.

Clear of your car when it's not safe to be there, by it if it is. It will usually oblige. A diesel running on petrol limps along quite willingly, and that is the catch: restart the vehicle to get to somewhere safer and the mixture goes further into the fuel system with every mile travelled. However awkward the place, it's no trouble for us to get to it, and that is a lot better for your car than carrying on.

Run it already? Stop, and check this

This is where your M5 comes into it — under 10 miles from Ashton under Hill. Some way along, and onto it in the first place: a misfuelled diesel will often do both before anything feels wrong. What you get then is seldom a clean stop. Power ebbs away, your idle goes lumpy, and there may be smoke.

Take the next junction that's sensible, pull up there, and never start it to move it. Long run? Anything approaching the under 15 miles to the closest city and you should suppose the lot — filter, pump, injectors, all of that arrived at by the petrol. Say that on the phone, as it alters what goes in our van.

What happens when our engineers reach you in Ashton under Hill

  • We ask first, quote after. What got in? How much? Has the engine run? Those replies shape what the work actually is.
  • The contaminated mixture is pulled from the tank.
  • Fuel lines are flushed through and the filter cleared, leaving nothing in the system that created any of this.
  • We pour clean diesel in and bleed the system.
  • We turn it on and confirm it runs correctly on clean diesel.

The car is then ready for you to pull away. There is no need for a workshop at any stage, as the work is all done where the vehicle is, and when it's spotted early, lasting damage is very unusual.

A distinct matter: AdBlue in a diesel tank around Ashton under Hill

AdBlue instead of petrol? Then the first instruction is unchanged — your engine stays off — whereas this problem beneath it's a distinct one altogether. Petrol thins the diesel and removes the protection the system relies on. Urea dissolved in water, AdBlue, and in a diesel tank that causes corrosion and build-up.

Usually the more significant of the two, AdBlue — and the detail lives on its own Ashton under Hill page. Both are ours to deal with.

What a petrol-in-diesel fuel drain costs around Ashton under Hill

One number would not be fair here, because this isn't one job. These are the things that shift it:

  • Started? Driven? Either answer counts more than anything else on this list.
  • Wrong fuel in, against what your tank holds — that proportion.
  • Whether it was unleaded or AdBlue.
  • Access: the car's position, and whether working on it there's sensible for our van.

The vehicle, the quantity, whether it has run — give us those and the answer comes back straight and not as a range. For the vehicle at home that is going nowhere and isn't time-critical, works too.

Ashton under Hill motorists ask us these about petrol in diesel

At a petrol station around Ashton under Hill, can you do a fuel drain there?

A big share of this work happens there, so yes. Our technicians attend Texaco and the other forecourts around town routinely, with the site's agreement — tell us which one you're at when you call and we'll tell you whether we can work there.

Is there a safe quantity of petrol in a diesel?

Whether your engine has run counts a lot more, though the ratio counts too, instead of the litres. A nearly empty tank with five litres in it, against a full one with the same five: separate scenarios, definitely. Either way, the work required comes down to one thing, which is whether your fuel system has had that mix pulled through it.

I put petrol in my diesel and drove the vehicle. What now?

Stop somewhere sensible, turn off, and keep it off. Not restarting it is the single most valuable thing available to you now. Driving does shift the problem out of that tank then into your pump and injectors, yes, and it remains salvageable far more frequently than motorists assume.

Is a fuel drain going to void my warranty?

No. Carried out correctly, draining and flushing is no modification at all, and the warranty from your manufacturer is unaffected by it. Running a diesel on petrol is the thing likelier to cause a disagreement with one, which is another reason to leave the car switched off.

Could I put some two-stroke in and just drive?

Two-stroke oil solves a separate issue, and an old one at that. Nothing it does puts back what petrol diluted. No. Petrol stays in that tank after that, whatever else goes in, and your pump gets no break from it.

Does petrol in a diesel have to go to a main dealer?

Wherever the car is, our technicians drain and clean it there, so a trip to the main dealer doesn't come into it.

You, and the car, still together?

The motor stays off.

Switch it off somewhere sensible then leave it off, if you have already driven it. Cold, stationary, going nowhere: that is the best place to be in. Motorists fear this much more than they need to.
