Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Old Town?

With that tank still carrying the fuel and the motor not yet turned over, nearly every job needs only a drain, so leave the motor off. That outcome is settled in the minutes immediately after filling up, and not by the amount that went in. Throughout Old Town and the remainder of Scottish Borders, Petrol in Diesel drains your car and cleans it where it is, whether at a roadside, on a drive or at a forecourt. Ring us before all else starts, so you'll hear what comes next.

Petrol in a diesel: what to try now

  • While you drive, the pump and your injectors suffer. That's why you don't fire it up, and why you don't believe it once it has started. The trick about petrol in a diesel in particular — the point most people get wrong — is that it pulls away happily for the first mile or two. Diesel in a petrol engine generally cannot run at all, which stops the motorist and stops the harm with them. This one lets you drive on.
  • Flicking the car's ignition on frequently primes the system, and priming is what draws petrol out of your tank and into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it ignites. Petrol handles the burning and none of the lubricating. Leave the ignition off.
  • Topping up gets rid of nothing. It gives you a bigger tank of the same mixture, because a diesel fuel system does not cope with petrol by percentage in the way that advice implies — so do not put diesel on top to weaken it. Octane is irrelevant too: super unleaded is petrol.
  • Remain where you are if you reasonably can. A motor that has never shifted is the simplest one to sort, and our team would much rather get to an odd location than have it started. If you're stopped on the verge on Tea Street, put those hazards on and leave the vehicle there.
  • Before you ring, get your position. Anything nearest to you with a name on it, plus a postcode starting TD1 3 — that's what decides whether the technician shows up or circles.
  • Three replies decide your whole job: the stuff you put in, the rough volume involved, plus whether it has been going since. The line is 0333 366 0103.

Quarter past eight. A quick refuel on the way in. Somewhere around eleven it dawns on you, and by then the diesel Volkswagen Golf has waited at Galashiels for three hours. Phone and keep the car where it is. What counts is the run in, because diesel both burns and — before that — lubricates the pump and the fuel injectors, but petrol only ever combusts. Those couple of miles worked your pump on a fuel robbed of a great deal of its protection, and no volume of standing in a car park puts any of it back. Hence the thing we ask about mileage instead of hours standing, and hence the advice to leave your keys be until our engineers arrive.

Our technicians will come out to you, drain your tank, rinse your fuel lines then put clean diesel in so you can drive home. So if petrol went into your diesel Renault Megane around Old Town and you are sat at Tesco Extra with a boot full of shopping, phone us — and never crank it a second time to get out of the spot. A mile or so at light throttle uses little diesel, which is why these are often the simple ones.

Twenty to nine. Outside the local primary school. Late already, and the till receipt in your hand reads unleaded. Put the hazard lights on, leave the engine alone, and call us. You might think three miles is nothing, in your Skoda Octavia or anything else — except that fuel is metered on demand, and a drive taken in a hurry asks for a great deal of that.

Do not drive it home to buy yourself time. You already have it: nothing gets worse while the vehicle sits, because a diesel Peugeot 308 left outside Scott Park is doing none of what it did on the way there. The pump has stopped turning.

Why so firm about leaving the keys alone? Since your pump is upstream of the injectors, and a wearing one sends whatever it sheds downstream with your fuel. Ring us. Leave the Nissan Qashqai close to Mercat Cross.

Mobile fuel drain van at a diesel car in Old Town

Can petrol be drained out of a diesel on a forecourt?

Forecourts are where the job usually begins, and where a good portion of that finishes. The drain generally gets done on the spot. Still on the forecourt at Asda? Given the site's consent, that is a place we work, and regularly.

No place except a forecourt can the mistake be spotted with the engine still unstarted. Anywhere else — a car park, a private drive, a lay-by — the vehicle was fired up and driven to get there, which means fuel was pulled from that tank, through your filter then into your high-pressure pump. That is not a catastrophe, and our technicians can still deal with it where it is. It does mean the lines and the filter need rinsing as well as that tank, and that's decided by the few seconds between seeing the receipt and reaching for the key.

Clear of the petrol pump, the next driver can get past — so yes, let the staff help you wheel the vehicle. Well worth it. Firing the car just to roll four vehicle lengths isn't.

Places we cover in Old Town

Galashiels, Gala Park, Balmoral, Glenfield, Halliburton — each of these on the runs that take us across to Old Town as well, a residential suburb.

Not on the list? That tells you nothing. The names above are just the nearest few, and the majority of places across Scottish Borders have a page of their own elsewhere on the site. Guessing is the thing to resist, particularly on a border or anywhere a satnav struggles. Ring us to ask.

See the map for the patch included on this page. The lot is territory our engineers serve: a roadside, a forecourt, a drive, a car park. You do not move your vehicle anywhere.

Stopped by the kerb somewhere in Old Town?

Not everyone finds a decent place to pull in. Hazards on in a lay-by somewhere, or stopped on the verge of Elm Row since you realised after setting off — our engineers take that call often enough that it's the normal kind.

Whether you remain with your car or step clear of it hangs on whether staying nearby seems sensible. Never fire up the engine to limp the car somewhere better — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling that mixture further into the fuel system. However tricky the location, it's no problem for us to come to it, and that's far better for the vehicle than carrying on.

Driven it already? Pull over, and read this

under 50 miles out of Old Town, your M8 is what counts here. Some way along, and onto it in the first place: a misfuelled diesel will often do both before anything seems wrong. What you get then is seldom a neat stop. Power ebbs away, the idle turns rough, and there may be smoke.

The next sensible exit is the one to take. Turn off there, then leave the restarting alone. Assume the worst of that on a long run. Anything approaching the under 50 miles to the closest city, and the mixture has been through the filter, through the pump, through the fuel injectors. Say so when you call. What we bring alters.

All about Old Town

Old Town is a suburban area situated on the riverside in the Scottish Borders, with a mix of flat housing and other residential properties. Old Town sits at an elevation of around 130 metres, close to the nearby towns of Galashiels and Gala Park. Old Town is located near Edinburgh, which is approximately 27.8 miles away, and is part of the wider Scottish Borders region. Old Town has a population of around 3636 people, according to recent estimates.

What we do when we arrive with you around Old Town

  • Three things get asked before any price — your fuel that got in, the amount, and whether anything has been run since. Each answer alters the work.
  • Our engineers drain that tank of the tainted mixture.
  • Lines cleaned, filter cleared. Whatever is left after that isn't the thing that started the trouble.
  • New diesel goes in, and then the fuel system gets primed.
  • It is fired up with new diesel in it, and our technicians check that it is running properly.

The vehicle is then ready for you to pull away. There is no need for a workshop at any stage, since the work is all done where the car is, and when it's noticed quickly, long-term damage is very rare.

A different problem: AdBlue in a diesel tank in Old Town

AdBlue rather than petrol? Then the opening step is unchanged — your engine stays off — while the issue beneath it is a distinct one altogether. Petrol does two things to diesel: weakens it, and removes the protection your fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it brings corrosion and build-up in its place.

Usually the more serious of the two, AdBlue — and the details lives on its own Old Town page. Both are ours to deal with.

Old Town costs for a petrol-in-diesel fuel drain

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

  • Has it been started or driven? Nothing else matters for as much.
  • Wrong fuel in, against what your tank holds — that ratio.
  • Which was put in: unleaded or AdBlue.
  • Where your vehicle is, and whether a van can safely get to and work on it.

The vehicle, the quantity, whether it has run — give us those and the answer comes back firm instead of as a range. For your car at home that's going nowhere and is not urgent, is fine too.

Petrol in diesel queries from Old Town drivers

Fuel drains on a Old Town petrol station forecourt

A big share of this work gets done there, so yes. Agreement from the site is the condition. Given that, a forecourt like Shell is somewhere we are often enough, along with the rest of them locally — so name yours on the call and you'll hear whether working there's possible.

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

Litres aren't the yardstick. Ratio is, and far more than either, it matters if anything has been run. Five litres in a nearly empty tank is a different case from five in a full one — but either way, the thing that settles how much work is required is if that mix has been drawn through your fuel system.

Petrol in my diesel, and I have driven the vehicle

Somewhere sensible, then stop, then switch off and leave it off. Not restarting it is the single most useful thing available to you now. Driving does move the trouble out of the tank and into the pump and injectors, yes, and it stays fixable far more often than drivers expect.

My warranty — does a fuel drain void it?

No. Carried out correctly, emptying and purging is no change 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 a dispute with one.

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

Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol thinned. No. The pump still has to cope with it, since that 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, as we drain and flush the vehicle wherever it is.

Waiting next to it?

Keep the engine turned off.

If you have already driven the vehicle, pull in somewhere safe, switch it off then keep it off. This is recoverable from much more frequently than motorists fear, and a stationary, cold car is the best position to be in.

At the roadside, on the forecourt or at home — on-site fuel draining around Old Town and across Scottish Borders.
