Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Sandford Hill?

With the tank still carrying the fuel and the motor not yet started, nearly every job requires only a drain, so keep the engine off. That outcome is decided in the minutes right after filling up, and not by the amount that was put in. All over Sandford Hill and the remainder of Staffordshire, Petrol in Diesel drains your car and flushes it where it stands, whether at a roadside, on a driveway or at a forecourt. Call us so we can explain what follows next before you try anything else.

Your first five minutes: petrol in a diesel

  • Feed a petrol engine diesel and it will typically not run at all, so the person stops there and so does the harm. Feed a diesel petrol and the car starts, it ticks over, it drives off — all right for a few miles. Drivers have that backwards, which is the thing they get wrong about petrol in a diesel specifically. So never crank it. And having started, never believe it: that fuel system is grinding while you drive.
  • Diesel combusts, and before it burns it lubricates — that injection pump, its injectors. Petrol manages only the burning. So leave the ignition off as well: turning it on is frequently all it takes to prime your system, and priming draws petrol from your tank into exactly those components.
  • Do not tip diesel on top to dilute it. A diesel fuel system will not cope with petrol by percentage in the way that advice suggests, and topping up removes nothing — it only leaves you a bigger tank of the same mix. The grade makes no difference either: super unleaded is just petrol.
  • We'd much rather get to a tricky spot than have it started — so if you safely can, stay still. Nothing is easier to handle than a vehicle that has never shifted. On the verge on Somerton Way, that means hazards on and keep the car.
  • Before you call, get your position. Anything closest to you with a name on it, plus a postcode beginning ST3 5 — that's what decides whether the van arrives or circles.
  • Call 0333 366 0103. Let us know what went in, roughly how many litres, and also whether your car has fired. These three replies decide the entire job.

Pump-side draining for petrol in a diesel

Plenty of this work begins at a pump, meaning a large portion of that ends up finished there. If you're still on the forecourt at Esso, that's normally where this drain gets done — we work on petrol station forecourts regularly, with the station's consent.

No place but a forecourt can this be spotted with the engine still unrun. Everywhere else — a car park, a driveway, a lay-by — your car was started and moved to get there, which means fuel was sucked from that tank, through your filter then into the high-pressure fuel pump. That is not a catastrophe, and we can still deal with it where it is. It does mean the fuel lines and the fuel filter need rinsing as well as that tank, and that's decided by the few seconds between reading your receipt and going for the keys.

The attendants will generally happily wheel it out from the pump so the next motorist can get through. That is worth doing. Shifting it four bays doesn't justify firing the motor.

Mobile fuel drain van at a diesel car in Sandford Hill

How much fuel the pump has drawn is what we're actually asking — not how long ago any of that was. So the phone call our engineers like runs like this: diesel Nissan Qashqai, a few litres of unleaded, a couple of miles driven, now shut off outside The Co-operative Food.

Nothing tells you, because from behind the wheel there is nothing to be warned about. Your diesel Dacia Duster will have seemed entirely usual on the way back from Gladstone Primary Academy, and they all do — which is the snag with petrol in a diesel instead of the reverse. Diesel in a petrol motor generally refuses to run, stopping the driver and stopping the harm with them. Petrol in a diesel starts, idles, moves off as though nothing had happened, and all the while the pump does its work without the protection its fuel is supposed to supply. Tell us roughly how far, and how hard. The harder matters more.

Diesel has to be thick enough to seal the tightly fitted components it passes through, and petrol dilutes it. That is the entire process, and it accounts for the normal Springfields Short call: a diesel Vauxhall Astra that travelled out there without fuss and came back down on power, lumpy at idle, perhaps smoking a little. A diesel injection system works hydraulically as well as chemically — it requires 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 the motor gets a poorer, later, less even delivery than it was designed about. None of that is your engine failing, which is the bit worth hearing: it's your fuel no longer behaving like diesel, and it stops when your fuel is sorted.

Ringing from near SS Mary and Chad Parish Church? Three things help us. The filler — which side of the car it is on. Room for a van alongside you, without the road being blocked. And if anything has run since the fill-up. The spot itself scarcely counts: on-street is where we work most, and we would far rather have a cramped space than a car a person has driven somewhere quicker. Then it's a drain for the Audi A6, a filter change where there's one worth changing, lines flushed, fresh fuel put round the entire system. By now the worst of it is in the lines and not the tank.

It got a few streets and stopped. The throttle went limp, the idle turned ragged, and the diesel Citroen C3 is now waiting near St John Oratory Chapel. That softness is the fuel failing to build pressure properly not your engine packing up — and as there is no warning light for it, vehicles in that position generally get driven a second time before somebody calls. Do not. Switch it off then phone us.

Areas our team cover near Sandford Hill

Sandford Hill is a residential suburb, and our vans go out to the town and to anywhere around it on the same rounds: Adderley Green, Longton, Meir Hay, Weston Coyney and Normacot.

If yours isn't on that list it doesn't mean we do not come — there are separate pages for most locations in Staffordshire, and the ones named above are simply the immediate neighbours. Contact us and enquire instead of presuming — boundaries particularly, and anywhere the satnav may struggle with.

This map shows the patch this page spans. Our technicians work at the roadside, at forecourts, on driveways and at car parks across all of that, and the vehicle doesn't need to travel to us.

Kerbside breakdowns across Sandford Hill

The opportunity to pull in somewhere sensible doesn't fall to everyone. If you noticed after setting off and finished up on the verge on Addington Way, or in a lay-by somewhere with your hazards on, that is a common call for us rather than a rare one.

Out of your car when it's not safe to sit inside, by it if it is. Never restart the engine to nurse the vehicle somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling the blend further into the fuel system. A van coming to a tricky spot is no bother for us, and it is much better for the vehicle than pressing on.

Already driven it? Petrol in a diesel over a couple of miles

under 5 miles from Sandford Hill, the local M6 is what matters now. A misfuelled diesel will frequently get you onto it and some distance along before anything feels wrong, and the symptoms when they come are usually a drop in power, a lumpy idle and smoke rather than a clean stop.

Take the next exit that is sensible, stop there, and don't start the vehicle to reposition. It changes what our technicians bring, so mention it when you ring: on a longer run — anything approaching the under 3 miles to the nearest city — take it the mixture has been through your filter, your pump and your injectors.

Our job around Sandford Hill, step by step

  • Three things get checked before any quote — your fuel that got in, the quantity, and if anything has been run since. Each answer changes the work.
  • That tank is drained completely.
  • Our technicians flush your fuel lines and clear the filter, and so what's remaining in your system isn't what created the problem.
  • New diesel goes in, and then the fuel system gets bled.
  • The engine is started and tested to make sure it runs properly on clean diesel.

At that point it is ready to set off. Our engineers do all of this wherever the vehicle has come to a stop, which means it never needs to go to a workshop, and when it has been caught soon, it is very uncommon for there to be lasting damage.

AdBlue in a diesel tank in Sandford Hill is a separate problem

The problem isn't the same, though the first rule is — don't crank it — if what was put in was AdBlue instead of petrol. Petrol does two things to diesel: thins it, and strips out the lubrication your fuel system relies on. AdBlue? Urea dissolved in water. Put that in with the diesel and you get corrosion instead, plus build-up.

AdBlue removal around Sandford Hill has a page of its own with the detail on it, including why it is often the more significant of the two. We cover both.

How much is a petrol-in-diesel drain in Sandford Hill?

Honestly, no single price fits on a page like this. This job differs. Here is what changes 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 your tank holds.
  • Whether it is unleaded or AdBlue.
  • Access: the vehicle's position, and whether working on it there's safe for our van.

Tell us what your car is, how much got in, and whether the motor has run. A firm answer comes back, not a range. If it isn't time-critical — the vehicle is at home and going nowhere — works too.

Things our technicians get about petrol in diesel around Sandford Hill

I'm on a forecourt around Sandford Hill. Can you drain it on the spot?

Yes — forecourts are where a big part of this gets done. Consent from the site is the condition. Given that, a forecourt like BP is somewhere we're frequently, along with the rest of them locally — so name yours on the call and you'll hear if working there's possible.

How much petrol in a diesel is too much?

Litres are not the yardstick. Proportion is, and a lot more than either, it matters if anything has been run. What settles how much work is needed is whether that mixture has been drawn through your fuel system — because though five litres in an almost empty tank is a distinct matter from five in a full one, either way that is the query.

Already driven it with petrol in your diesel? Now what?

Pull in somewhere safe, turn off, then keep it off. It's fixable far more frequently than motorists assume, even though driving is what takes the trouble from the tank into your pump and injectors — and the single most helpful thing you can do now is not restart it.

Is a fuel drain going to void my warranty?

No. Carried out correctly, emptying and rinsing is no alteration at all, and the warranty from your manufacturer is unaffected by it. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.

Two-stroke oil in that tank, and then home?

What petrol has weakened is not put back by two-stroke oil, which is an old workaround for a separate fault. So no. Later? Still petrol in the tank, and a pump that has to cope with the stuff.

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

No. Our engineers drain and flush the car wherever it is, so there is no need to take it to a dealership.

Still with your vehicle?

The motor remains off.

Driven it already? Then somewhere sensible, stop, switch off, and no restarting the vehicle afterwards. Cold, parked, going nowhere: that's the best position to be in. Motorists fear this a lot more than they need to.
