Petrol in Diesel

Petrol in a Diesel Car in Netherton

Never start the motor. If the fuel is still sitting in that tank and your engine has not been started, a fuel drain is nearly always all it needs — and that's decided in the next few minutes, not by how much went in. Petrol in Diesel drains and flushes wrongly fuelled cars where they sit, all over Netherton and the remainder of Devon, on the forecourt, at the roadside or on a private drive. A single ring our way will be sufficient: our engineers will tell you what comes after this. Try this right away.

Now what? Petrol in a diesel, step by step

  • Give a petrol motor diesel and it will generally fail to run at all, and so the person stops there and so does the damage. Feed a diesel petrol and the car starts, it ticks over, it pulls away — fine for several miles. Drivers have that backwards, which is the thing they get wrong about petrol in a diesel specifically. So don't fire it up. And having started, never depend on it: that fuel system is wearing while you drive.
  • Diesel burns, and before it burns it protects — that injection pump, those injectors. Petrol handles only the burning. So leave your ignition off too: switching it on is often enough to prime your system, and priming carries petrol from the tank into precisely those components.
  • That advice supposes a diesel fuel system handles petrol by percentage. It will not. Add diesel on top and nothing at all is taken out; what you end with is a bigger tank of the same blend. And no, the type makes no difference — super unleaded is simply petrol.
  • A car that has never moved is the easiest one to deal with, and so stay where you are if you sensibly can. Stopped on the verge on Cross Hill? Hazards on, then leave the vehicle there. An awkward place suits us better than a started motor.
  • Our van turning up instead of circling rests on two things: a postcode beginning TQ12 4, and whatever is nearest to you with a label on it. Keep both prepared before you dial.
  • Dial 0333 366 0103. Anticipate three points — what went in, approximately how much, plus if the engine has been started. Those replies determine whatever comes after.

The high-pressure fuel pump did that morning run labouring on a liquid that had shed much of the protection it is designed around. Diesel protects that pump, and the injectors with it, before any of the fuel burns; petrol does the burning and none of the lubricating. So imagine a diesel Volkswagen Golf, filled at quarter past eight, driven in to work, and parked sitting at Newton Abbot until you realise around eleven. Three hours of standing have changed nothing about it. The few miles before that altered a good deal, which is why the question our engineers ask you is about distance instead of time. Ring us. Keep the car exactly where it stands.

Don't risk it. The trip home from The Wild Goose Inn is entirely possible, which is precisely the trouble — a diluted tank doesn't stop a diesel starting or pulling away, it just wears down the components the fuel is meant to protect. Phone us, and let the Audi A4 stay where it sits.

Nothing gets worse whilst it sits. Whatever your diesel Mercedes C-Class did on the way to Stokeinteignhead Cricket Club, it's doing none of it now: the pump is not turning. So take your time — but do not drive it home to buy yourself any.

Clearing your Dacia Duster, changing the fuel filter where there's a workable one, flushing the lines, putting fresh fuel through the whole system: that is this job, and it's shaped by the worst of it sitting in the lines rather than in that tank by this point. Three things help when you call from near Combeinteignhead Village Hall — which side the filler is on, whether a van can stand alongside without blocking the road, and whether the motor has run since you filled up. On-street is the commonest spot our engineers work, and so the spot itself is seldom the trouble. A cramped parking spot is better than a car driven somewhere more handy.

Drain it and put clean diesel in — that's the suggestion you will get, generally from a person sure of themselves, and it is half right. Do precisely that to a diesel Citroen C3 by St Blaise and it would start, which is what makes the advice sound sensible. What takes place next is the issue: your engine straight away sucks the petrol left resting in the fuel filter and the feed lines straight back through your pump, because emptying a tank does nothing about fuel that has already left it. Ring us instead. Our technicians flush your circuit and take your filter off where the vehicle has a workable one, which is the difference between your car being repaired and the vehicle just starting.

Pump-side draining for petrol in a diesel

A fair portion of the work gets finished at the pump, as that's where it often starts. If you're still at the forecourt at Sainsbury's, that is usually where this drain gets done — we work on station forecourts all the time, with the station's consent.

Before the engine has run — a garage is the single spot the mistake is spotted. The few seconds between checking the receipt and going for the keys decide how much requires flushing. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the car was switched on and driven to get there, so fuel was pulled from the tank, through your filter then into your high-pressure pump. That means the lines and the fuel filter require flushing as well as your tank. It's not a calamity, and our technicians can still sort it out where the vehicle is.

Wheel the vehicle out of the way if the attendants volunteer, and they usually will. The next customer gets past the petrol pump, and that's worth doing. Rolling it four lengths does not warrant starting it.

Netherton and the places next to it

Combeinteignhead, Haccombe, Buckland, Newtake, Aller Park — every one of these on our journeys that take us across to Netherton as well, a rural hamlet.

If yours is not on this list it doesn't mean we do not come — there are dedicated pages for the majority of places around Devon, and the ones listed above are just the nearest neighbours. Ring us to check rather than guessing — borders above all, and anywhere your phone might get wrong.

See our map for the patch shown on this page. The vehicle doesn't need to move to us. We operate over every bit of it — roadside, forecourts, driveways, car parks.

Netherton: broken down wherever you pulled up

A chance to pull in anywhere safe does not come to everybody. A routine call for us rather than an odd one: worked out after setting off, ended up on the verge beside Shaldon Road or at a lay-by with your hazards going.

Safe where you are? Stay beside it. Not okay? Step out and away from it. Do not start up your engine to limp the vehicle somewhere better — a diesel running on petrol will frequently oblige, and every mile it obliges for is drawing that mixture further into your fuel system. A technician driving to a tricky place is no trouble for us, and it is much better for the vehicle than carrying on.

Some miles on petrol in a diesel: what next?

under 15 miles out of Netherton, the local M5 is what counts here. A loss of power, a lumpy idle, some smoke: those are the signs when they arrive, instead of a neat stop — and a misfilled diesel will frequently get you onto it and some way along before anything feels wrong at all.

Pull off at the first sensible exit, switch off, and never start the vehicle to reposition. Suppose the worst of that on a long trip. Anything approaching the under 15 miles to the nearest city, and the petrol has been through the filter, through the pump, through your injectors. Tell us when you ring. What our engineers bring differs.

About Netherton

Netherton is a small coastal hamlet in Devon, situated near the towns of Combeinteignhead and Haccombe. Netherton lies at a low elevation of around 12 metres, close to the sea and approximately 13 miles from the city of Exeter. Netherton is characterised by its predominantly detached housing stock, reflecting its rural setting. Netherton is part of a wider network of small settlements in the area, including Buckland.

Once our technicians reach you in Netherton: what follows

  • We ask first, quote after. What was put in? How much? Has the motor run? Those answers alter what the work actually is.
  • Out comes the polluted fuel.
  • Fuel lines are cleaned through and your filter cleared, leaving nothing in your system that caused any of this.
  • Priming follows, once new diesel is in.
  • Your engine is started and checked to confirm it runs correctly on clean diesel.

Your car is then ready for you to pull away. Our technicians do all of it wherever the vehicle has come to a stop, which means it never has to go to a garage, and if it has been spotted quickly, it's very rare for there to be permanent damage.

Netherton AdBlue removal is a distinct matter

Never crank it: that opening step stands whether what was put in was AdBlue or petrol. What differs is this problem itself. The protection a fuel system depends on gets taken away by petrol, which dilutes your diesel. Corrosion and deposits are what a diesel tank gets instead, since AdBlue is urea dissolved in water.

Both are ours. There is a separate Netherton page for AdBlue removal, with the full story on it — including the reasons it frequently turns out to be the worse of the two.

How much is a petrol-in-diesel fuel drain in Netherton?

One price wouldn't be fair here, since this isn't one job. These are the things that change it:

  • This is the big one: whether your engine has been started, or driven.
  • The tank's capacity, set against how much of the wrong fuel went into it.
  • AdBlue or unleaded, whichever was put in.
  • Whether a van can safely get to the car and work on it, which rests on where the car is.

A straight answer rather than a range is what you get for telling us three things: the car, the quantity, and whether it has run. If it's not pressing — the vehicle is at home and going nowhere — is fine too.

Petrol in diesel: frequent queries around Netherton

At a petrol station around Netherton, can you do a fuel drain there?

A good share of this work takes place there, so yes. Tell us which one you're at when you phone and we will tell you whether our engineers can work there. With the site's consent our technicians attend Tesco and the other forecourts around town regularly.

A few litres of petrol in a diesel — too much?

It depends on the ratio rather than the litres, and far more on whether your engine has run. A nearly empty tank with five litres in it, against a full one with the same five: distinct scenarios, certainly. Either way, the work required comes down to one thing, which is whether the fuel system has had that blend drawn through it.

I drove the vehicle after putting petrol in my diesel. What now?

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

Is a fuel drain going to void my warranty?

No. Carried out correctly, clearing and rinsing is no alteration at all, and the warranty from your manufacturer is untouched by it. Another good reason to leave it turned off: running a diesel on petrol is the thing likelier to cause an argument with one.

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

No. Two-stroke oil is an old fix for a separate issue and it does not replace what petrol has weakened. The pump still has to live with it, since the tank still has petrol in it afterwards.

A main dealer for petrol in a diesel — needed?

There's no need to take it to a franchised dealer, since our technicians drain and flush your car wherever it is.

You, and your car, still together?

Never turn the engine on again.

Turn it off somewhere sensible and keep it off, if you have already driven it. This is recoverable from much more commonly than motorists assume, and a parked, cold vehicle is the best position to be in.

At the roadside, on the forecourt or at home — on-site fuel draining in Netherton and throughout Devon.
