Bottom Boat: Put Petrol in a Diesel Car?

If you have not started your engine as yet, do not. A fuel drain and nothing else is almost always what a vehicle needs while the petrol is still sitting in your tank and your engine has not turned over, which is why it's the following few minutes that count, not how much went in. Petrol in Diesel travels to your car wherever it has come to rest in Bottom Boat or the rest of West Yorkshire, on the forecourt, at the roadside or on a driveway, and drains and cleans it there. Just one call to us will be plenty: our engineers will explain what follows next. Make that straight away.

Your next five steps: petrol in a diesel

  • Don't start it — and do not depend on it when it starts. This is the bit most people have wrong about petrol in a diesel especially. A petrol motor given diesel generally just can't run, so the person stops and the harm ends with them. A diesel fed petrol generally starts, idles and pulls away perfectly well for several miles. It is not all right. It's eating into that fuel system as you drive.
  • Leave the ignition off also. Diesel does two jobs: it burns, and before it burns it greases that high-pressure fuel pump and its injectors. Petrol manages the first but not the second. Flicking your ignition on is commonly enough to prime your system, which carries that petrol out of the tank and into exactly those parts.
  • Never weaken it. Diesel added on top clears nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system handles petrol. Super unleaded? Simply petrol. The octane makes no difference.
  • Stay where you are if you safely can. A motor that has not shifted is the easiest one to deal with, and our team would sooner get to a tricky spot than have it started. If you're parked on the verge on Bottomboat Road, turn your hazards on then leave it there.
  • A van showing up instead of circling rests on two things: a postcode beginning WF3 4, and whatever is nearest to you with a label on it. Get both prepared before you dial.
  • Phone 0333 366 0103. Expect three points — what was put in, approximately how many litres, plus if the engine has been turned over. Your replies determine all that happens next.

How many miles you drove is what our technicians care about, not how long your car has been stood — and this is why. Diesel does two jobs on its way through an engine: it combusts, and before burning it lubricates its high-pressure pump and its injectors. Petrol handles the first only. So a fast fill-up on the drive in, the penny dropping around eleven, and a diesel Renault Clio standing outside Normanton since quarter past eight shows those few miles were done with the pump labouring on a fuel robbed of much of its protection. Ring us then leave the vehicle exactly where it sits.

Easy, these ones, and the reason is the distance: a mile at gentle throttle draws little diesel. Petrol into a diesel Dacia Duster somewhere around Bottom Boat, a boot full of shopping, and you sat at Co-op Food — phone us. Exiting that spot is not worth a restart. That tank gets drained where it sits, your fuel lines cleaned, new diesel in, and you get home.

Three replies decide much of the work: what was put in, roughly how much, and whether the engine has run since. We ask for them when we reach your car in the car park by The Rising Sun. Then the contaminated mix comes out of that tank, your lines are flushed, and where your Audi A3 has a replaceable filter, it comes off. Once clean diesel is in and your system primed, we fire it up and check it runs smoothly before you pull away.

Diesel has to be viscous enough to seal the tightly fitted components it flows through, and petrol thins it. That's the whole mechanism, and it accounts for the ordinary Stanley Marsh Nature Reserve call: a diesel BMW 5 Series that travelled out there without complaint and came back down on power, rough at idle, maybe smoking a little. A diesel injection system works hydraulically as well as chemically — it requires the fuel to hold pressure, not just to burn — so when the fuel dilutes, pressure that should build and stay built starts leaking past clearances instead, and the motor gets a poorer, later, less even delivery than it was engineered around. No part of that is the engine failing, which is the part worth hearing: it is your fuel no longer acting like diesel, and it stops when the fuel is sorted.

Most of these happen somewhere strange, and the cause is mechanical instead of careless — practically no resistance meets a smaller petrol nozzle entering a newer diesel filler neck. Two days into a diesel Ford Kuga, a fill-up near St Peters Church Centre that you did not think about? Phone us from where you are. Courtesy and hire cars go further before anybody notices it, and the further they go, the more petrol arrives at the fuel injectors.

Forecourt drains for petrol in a diesel

It kicks off at the pump, typically. Regularly the job ends on site too. Our technicians work on garage forecourts regularly, with the owner's consent, and so if you're still at Shell that's generally where this drain takes place.

At a garage, it is halted with the motor never started, and nowhere else does that. Fuel sucked out of your tank and through the fuel filter, all the way to the high-pressure pump, is what happens when your engine is started and the vehicle is moved to where it is now: the car park, the private drive or the lay-by, anywhere other than the forecourt. So the flush includes the fuel filter and your lines together with that tank. That's still not a disaster, and our engineers deal with it where the car is. What determines it is whether the key was reached for in the seconds after the receipt was checked.

The staff will generally help you wheel it out from the pump so the next customer can get past. That is worth doing. Four vehicle lengths isn't worth the risk.

Bottom Boat and the villages beside it

Stanley Ferry, Patrick Green, Stanley, Lee Moor, Methley Lanes — every one of these on our journeys that take us over to Bottom Boat too, a village.

If yours is not on the list it does not mean we never come — there are pages for the majority of locations around West Yorkshire, and the ones mentioned above are just the closest neighbours. Assuming is the habit to resist, above all on the border or anywhere a satnav gets lost. Call us to ask.

Check this map for the ground covered here. The vehicle never needs to travel to us. Our technicians work over all of that — kerbside, forecourts, driveways, car parks.

Bottom Boat: stuck where you parked

Not everyone finds a sensible spot to pull in. Set off, then noticed? Ended up on the verge on St Peters Crescent, or parked in some lay-by with the hazards going? That is a common call here. Not a rare one.

Safe there? Stay beside it. Not okay? Climb out and clear of it. Don't start up your motor to limp the vehicle somewhere safer — a diesel running on petrol will usually oblige, and every mile it obliges for is drawing the mix further into the fuel system. Carrying on causes the vehicle far more harm than our van heading out to an awkward spot, and that is no bother for us.

A few miles on petrol in a diesel: now what?

This is where your M62 matters, under a mile away from Bottom Boat. A loss of power, a lumpy idle, smoke: those are the symptoms when they appear, instead of a neat stop — and a misfilled diesel will often take you onto it and some distance along before anything feels wrong at all.

The next safe exit is the one to take. Switch off there, then leave the restarting alone. Suppose the worst of it on a long drive. Anything near the under 3 miles to the nearest city, and the mixture has been through your filter, through your pump, through your injectors. Tell us when you phone. What our engineers bring differs.

Where is Bottom Boat?

Bottom Boat is a small village in West Yorkshire, situated on the banks of the River Calder, with a mix of semi-detached housing and local amenities. Bottom Boat sits near the town of Wakefield, approximately 2.8 miles away, and is part of the larger urban area surrounding the city. Bottom Boat has a population of around 1191 residents and is located at an elevation of 37 metres above sea level, in a riverside setting that influences its character. Bottom Boat is close to nearby places such as Stanley Ferry and Stanley, which share similar geographical features.

The call-out around Bottom Boat, step by step

  • The replies change the work, which is why we ask before quoting: what got in, how much of it, and if the engine has run.
  • That tank gets emptied of it.
  • Our engineers flush the lines and clear the fuel filter, and so what is left in the system is not what started the trouble.
  • Our technicians put new diesel in and bleed your system.
  • We fire it up and make sure it runs properly on new diesel.

Then it's ready to pull away. Our technicians do all of it wherever the vehicle has come to a stop, which means it never needs to be taken to a garage, and if it has been noticed quickly, it is very unusual for there to be lasting damage.

AdBlue in a diesel tank in Bottom Boat is a separate problem

If what got in was AdBlue instead of petrol, the first instruction is unchanged — never crank it — yet the issue is not. The protection a fuel system relies on is taken away by petrol, which dilutes the diesel. AdBlue? Urea dissolved in water. Put that in with your diesel and you get rust instead, plus deposits.

We handle both, and AdBlue removal around Bottom Boat has its own page with the full story — including why it's frequently the more serious of the two.

Bottom Boat pricing for a petrol-in-diesel fuel drain

Our technicians cannot put one number on this page honestly, because the job is not one job. What shifts it:

  • Has it been run or driven? Nothing else matters for as much.
  • How much of the wrong fuel was put in, weighed against how much the tank can hold.
  • Whether it was unleaded or AdBlue.
  • Whether a technician can sensibly reach the car and work on it, which depends on where your vehicle is.

A straight answer rather than a range is what you get for telling us three things: your vehicle, the amount, and if it has run. Not pressing, with the vehicle at home and going nowhere? Then is fine.

Petrol in diesel questions from Bottom Boat drivers

Fuel drains on a Bottom Boat petrol station forecourt

Much of what our technicians do happens nowhere else. So yes. Tell us which one you are at when you ring and we will tell you whether we can work there. With the station's agreement our engineers work at JET and the other forecourts around town all the time.

How much petrol is too much for a diesel?

Litres aren't the measure. Proportion is, and far more than either, it counts whether anything has been run. A nearly empty tank with five litres in it, against a full one with the same five: different situations, certainly. Either way, the work needed comes down to one thing, which is whether the fuel system has had that mix sucked through it.

Petrol in my diesel, and I have driven it

Stop safely. Off. Nothing after that. Driving takes the issue along — out of the tank, into the pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one truly helpful thing left to you is not restarting the vehicle.

My warranty — does a fuel drain void it?

It is not a change, and so a drain and flush carried out correctly doesn't invalidate a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause an argument with one.

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

What petrol has thinned isn't restored by two-stroke oil, which is an old fix for a distinct issue. So no. After that? Still petrol in your tank, and a pump that has to cope with the stuff.

A main dealer for petrol in a diesel — necessary?

There's no need to bring it to a franchised dealer, as our engineers drain and flush the vehicle wherever it is.

Waiting next to it?

Shut off is how the car stays.

Already driven it? Then stop somewhere safe, turn off, then let it stay that way. This is recoverable from far more commonly than drivers expect, and a stationary, cold car is the best place to be in.
