Put Petrol in a Diesel Car in Barshare? Don't Start It
Petrol in Diesel drains and flushes wrongly fuelled vehicles where they stand, on the forecourt, by the roadside or on a driveway, all over Barshare and the remainder of East Ayrshire. The very first thing to do is not to start your engine. When the engine has not turned over and the petrol is still sitting in the tank, a drain is nearly always all it needs, and the coming few minutes settle that, not how much got in. Our engineers shall show you what the following part is. Call us — it comes ahead of anything else.
The next five minutes: petrol in a diesel
- Feed a petrol motor diesel and it will typically fail to run at all, and so the motorist stops there and so does the damage. Give a diesel petrol and the thing starts, it idles, it drives off — all right for a few miles. Motorists have that reversed, which is the part they get wrong about petrol in a diesel specifically. So don't fire it up. And once started, never believe it: that fuel system is wearing down as you drive.
- Turning the ignition on usually primes that system, and priming is what carries petrol out of the tank and into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it combusts. Petrol handles the burning and none of the protecting. Leave the car's ignition alone.
- Topping up takes out nothing. It gives you a bigger tank of the same blend, since a diesel fuel system doesn't tolerate petrol by percentage in the way that guidance suggests — so don't tip diesel on top to water down it. Grade is immaterial too: super unleaded is petrol.
- Remain where you are if you reasonably can. A motor that has never shifted is the easiest one to deal with, and we'd sooner come to an odd spot than have it started. If you are pulled up on the verge on Barshare Road, turn the hazards on then keep the vehicle there.
- Keep your location prepared before you phone. A postcode that starts KA18 1 and whatever is next to you with a name on it is the difference between a van arriving and a van circling.
- Dial 0333 366 0103. Expect three things — what was put in, roughly how many litres, plus whether the engine has been turned over. Those replies decide everything that comes after.
The drive back would roughly double it, for no gain at all. One commute has already sent a real quantity of petrol-thinned diesel through the high-pressure pump of that Volkswagen Golf. So leave the car where it stands. Phone us from the platform if that is handier — nobody needs you hovering over the vehicle outside Auchinleck while our engineers get on, and tonight trumps finding out on Monday.
You'll be told to shift the car clear of that gateway and sort it out later. Please don't. On the zig-zags by the local primary school, a misfilled Skoda Octavia running on diesel is in the way, and that's all it is. Fire it up three more times being polite and you have turned a tank into a fuel system: every start primes the fuel lines, every prime draws more petrol past the fuel filter toward your pump. Let them complain. Call us.
Fine on the way out, sluggish on the way back. If that's how that trip to Shankston Wood went, that tank is where to look. Petrol thins diesel, and thinner fuel seeps past the precision components that are meant to build injection pressure — so the further the Peugeot 308 went, the less well it held that pressure. Stop somewhere safe, switch off and phone us.
Three things help when you phone from close to Townhead Park: which side the filler is on, whether a van can pull up next to without blocking the road, and whether the motor has run since you filled up. On-street is the most common spot our technicians work, so the location itself is rarely the issue — we would much rather deal with a tight parking space than with a car that has been driven to somewhere more handy. We'll drain your Audi A4, change your filter where there's a serviceable one, flush the lines and put fresh fuel through the full circuit, because by this point the worst of it is sitting in the lines instead of in that tank.
Someone certain will tell you to drain the car then put clean diesel in. Half right, that. Try it on a diesel Mercedes E-Class near St John's RC Church and the motor will start — which is exactly why it sounds like sense. Here's the trouble: there is petrol left in the filter and the feed lines, and the first thing the engine does is suck it back through your pump again. Emptying a tank achieves nothing about fuel that already left that tank. Call us. Your system gets flushed, the fuel filter comes off where there's one worth removing, and that is what separates a fixed car from one that just starts.
Pump-side drains for petrol in a diesel
A good share of the work ends up done at a forecourt, since that's where it mostly begins. We work on garage forecourts routinely, with the site's consent, so if you are still at the nearest petrol station that's normally where this drain happens.
At a forecourt, this gets caught with the engine never run, and no place else does that. Our engineers can still put it right where it is, even away from the pumps. In a car park, on a drive or in a lay-by, the vehicle has been switched on and moved there, and that drew fuel through the fuel filter then into the high-pressure pump, right from the tank. None of that is a calamity, but the flush then has to reach past your tank to the lines and the fuel filter, and the few seconds between reading your receipt and reaching for the keys are what decide that.
The attendants will generally help you move the car clear of the pump so the next motorist can get by. That's worth doing. Shifting it four bays doesn't warrant cranking it.
Can we cover your corner of Barshare?
Craigens, Netherthird, Cumnock, Logan, Holmhead — each of those on the rounds that carry us over to Barshare as well, a residential suburb.
There are separate pages for the majority of locations around East Ayrshire, and the ones named above are simply the immediate neighbours — so yours being absent from this list says nothing whatsoever about if we come. Contact us to enquire rather than assuming — boundaries above all, and anywhere a satnav tends to misread.
That map marks the area the page spans. Kerbside, forecourt, drive, car park: every bit of it is ground we work on, and none of it requires the vehicle to move to us.
Stopped by the kerb somewhere around Barshare?
A chance to stop somewhere safe does not come to everybody. If you realised after setting off and finished up along the verge on Jubilee Court, or in a lay-by somewhere with the hazards going, that's a normal call for us and not a rare one.
Remain by the vehicle while it is sensible to sit there, but clear of it when it is not. Every mile a diesel obliges you for on petrol draws that blend further into the fuel system — and oblige it frequently will, which is why the engine doesn't get restarted to limp somewhere better. However difficult the location, it is no bother for us to get to it, and that's much better for your car than driving on.
Run it already? Stop, then see this
Here is where the M77 comes into it — under 25 miles away from Barshare. A misfuelled diesel will usually get you onto it and some distance along before anything feels wrong, while the signs when they come are generally a loss of power, a rough idle and smoke rather than a tidy stop.
Take the next junction that is safe, stop there, and never restart the car to move it. Long drive? Anything close to the under 50 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that got to by the mixture. Say that on the call, as it changes what goes in our van.
Barshare itself
Barshare is a suburban area situated on the riverside in East Ayrshire, with a mix of terraced housing and a population of around 2385 residents. Barshare sits at an elevation of 137 metres, near the communities of Craigens, Netherthird, and Cumnock. Barshare is located approximately 28 miles from Glasgow, making it a commuter base for the city. Barshare's riverside setting provides a distinctive character to the area.
The call-out around Barshare, step by step
- Three things get checked before any price — the fuel that went in, the quantity, and whether anything has been run since. Each answer changes the work.
- Away comes the tainted fuel.
- What is left in your system shouldn't be what created the issue, and so your fuel lines get cleaned and your filter cleared.
- Clean diesel goes in, and then your system gets primed.
- It is started with new diesel in it, and our technicians make sure that it is running properly.
Your car is then ready for you to pull away. All of this is done where the car is, so it never needs to be taken to a workshop, and when it has been noticed early, permanent damage is very uncommon.
AdBlue in the diesel tank instead, in Barshare?
AdBlue instead of petrol? Then the first step is unchanged — your motor remains off — while the issue underneath it is a different one altogether. The lubrication a fuel system depends on is taken away by petrol, which thins your diesel. AdBlue is urea in water, and in a diesel tank it leads to rust and build-up instead.
AdBlue removal in Barshare has a page of its own with the details on it, including why it is often the more serious of the two. Our technicians handle both.
Barshare pricing for a petrol-in-diesel drain
One figure wouldn't be honest here, as this isn't one job. These are the things that shift it:
- Started? Driven? Either answer counts more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Which went in: petrol or AdBlue.
- Access: the car's position, and whether working on it there is safe for our van.
A firm answer instead of a range is what you get for telling us three things: the vehicle, the amount, and if it has run. Vehicle at home, going nowhere, nothing pressing about it — is ideal for that.
Questions our technicians get about petrol in diesel in Barshare
At a petrol station in Barshare, can you do a fuel drain there?
Yes — forecourts are where a good portion of this happens. Our technicians visit JET and the other forecourts locally routinely, with the owner's consent — tell us which one you're at when you phone and we will tell you if our technicians can work there.
How much petrol in a diesel is too much?
It rests on the ratio instead of the litres, and far more on whether the motor has run. Five litres in an almost empty tank is a separate matter from five in a full one — but either way, the thing that determines how much work is required is if that mix has been sucked through the fuel system.
I drove the car after putting petrol in my diesel. Now what?
Pull over somewhere sensible, turn off, and leave it off. Driving shifts the issue along — out of the tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really valuable thing left to you isn't restarting the car.
Will a fuel drain void my warranty?
It isn't an alteration, and so a drain then flush carried out correctly does not invalidate a manufacturer's warranty. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Adding two-stroke oil, then driving home
No. It belongs to a different fault from a bygone era, and petrol has diluted something no oil of that kind replaces. The pump still has to put up with it, because your tank still has petrol in it after that.
Main dealers and petrol in a diesel
Wherever the vehicle is, our engineers drain and flush it there, so a trip to the main dealer does not come into it.
You, and your car, still together?
Leave it shut off.
Already driven it? Then stop somewhere sensible, turn off, then let the vehicle remain that way. Cold and stationary, a vehicle is in the best position available — and drivers fear this much more than the recovery rate warrants.
Throughout East Ayrshire and in Barshare: call-out fuel draining, at home or on the forecourt or at the roadside.
