Put Petrol in a Diesel Car in Goodwick? Don't Start It
If you have not fired up the motor yet, don't. A drain and nothing more is nearly always what a motor needs while the fuel is still sitting in that tank and the engine has not turned over, which is why it's the next few minutes that matter, not how much was put in. Petrol in Diesel goes to your car wherever it has stopped in Goodwick or the remainder of Pembrokeshire, on the forecourt, by the roadside or on a private drive, and drains and flushes it there. Ring us before everything else begins, and you'll hear what happens after that.
The next five steps: petrol in a diesel
- Feed a petrol motor diesel and it will generally fail to run at all, and so the driver stops there and so does the wear. Give a diesel petrol and the engine starts, it ticks over, it pulls away — all right for several miles. Motorists have that reversed, which is the bit they get wrong about petrol in a diesel specifically. So never crank it. And having started, don't depend on it: the fuel system is grinding while you drive.
- Leave your ignition off also. Diesel has two tasks: it burns, and before it combusts it greases that high-pressure pump and the injectors. Petrol manages the first but not the second. Flicking your ignition on is commonly enough to prime that system, which draws the petrol out of the tank then into exactly those components.
- Never add diesel on top to dilute it. A diesel fuel system will not accept petrol by percentage the way that advice presumes, and topping up takes out nothing — it only gives you a larger tank of the same blend. The grade makes no difference either: super unleaded is simply petrol.
- Wait where you are if you sensibly can. A motor that has never moved is the quickest one to handle, and we'd sooner get to an odd place than have it started. If you are parked on the verge on Main Street, turn those hazards on and keep it there.
- The van arriving rather than circling hinges on two things: a postcode starting SA64 0, and whatever is closest to you with a name on it. Get both prepared before you phone.
- Dial 0333 366 0103. Tell us what got in, approximately how much, and also whether your car has fired. These three facts decide the entire call-out.
Never take it home. Petrol-thinned diesel has passed through your injection pump in real volume on the road in, and the trip back would more or less double that for nothing at all. Call us — the platform is fine. There's no need to stand over your Volkswagen Passat outside Fishguard & Goodwick while the work goes on, and we would very much rather talk to you tonight than discover on Monday.
Twenty to nine outside the local primary school, already late, and your receipt in your hand says unleaded. Hazards on, engine off, call us. Three miles in your Skoda Octavia feels like nothing, but a diesel pump delivers fuel to demand — while a hurried morning drive asks for plenty.
Normal on the way out, flat on the way back. If that's how the run to The Rec went, the tank is where to look. Petrol thins diesel, and thinner fuel slips past the close-fitting components that are meant to build injection pressure — so the farther the Audi A4 went, the less well it held that pressure. Pull over somewhere sensible, turn off and phone us.
The pump rests upstream of your injectors, and so whatever a wearing one gives off travels on with your fuel — which is why we're blunt about not driving on. Call us, then leave the diesel Ford Focus where it is close to Phoenix Community Centre.
Somebody certain will tell you to drain the vehicle and put fresh diesel in. Only half right, that. Try it on a diesel Peugeot 208 close to Holy Name Church and your engine will start — which is precisely why it sounds like sense. Here's the problem: there is petrol left in your filter and the feed lines, and the first thing the engine does is pull it back through the pump a second time. Emptying a tank achieves nothing about fuel that already left your 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 vehicle from one that simply starts.
Clearing petrol from your diesel at the forecourt
A large chunk of the job ends up completed at a forecourt, as that is where it usually starts. If you are still at the forecourt at Esso, that is normally where the drain gets done — we operate on petrol station forecourts regularly, with the owner's permission.
Before your engine has fired — a forecourt is the only place it is caught. Fuel drawn out of that tank and through the fuel filter, all the way to the high-pressure pump, is what occurs when the engine is started and your car is driven to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush takes in your filter and the fuel lines together with that tank. That is still not a disaster, and our technicians deal with it where the vehicle is. What settles it is whether the key was reached for in the seconds after your receipt was checked.
Out from the pump, the next driver can get by — so yes, let the staff help you move it. Very much worth it. Shifting the car four bays doesn't warrant cranking the motor.
Service near Goodwick
These same runs carry us to Harbour Village, Stop-and-Call, Dyffryn, Cilau and Penyraber as well as Goodwick, which is a coastal town.
If yours isn't on this list it does not mean we do not come — there are separate pages for nearly all towns across Pembrokeshire, and the ones mentioned above are merely the closest neighbours. On a border, or somewhere the satnav misreads? Contact us and check rather than guessing.
This map shows the area this page spans. Our technicians work at the roadside, at forecourts, on driveways and in car parks throughout all of it, and the car does not need to move to us.
Stranded on the kerbside somewhere in Goodwick?
Not everyone has a safe place to stop. Set off, then realised? Finished up by the verge of Goodwick Hill, or sat in some lay-by with the hazard lights on? That's a routine call here. Not an unusual one.
Clear of the motor if it's not wise to wait inside, by it if it is. It will often oblige. A diesel running on petrol limps along perfectly willingly, and that's the catch: start it up to reach somewhere better and the mixture goes further into the system with every mile travelled. However inconvenient the location, it is no trouble for us to come to it, and that is far better for the car than carrying on.
Driven it already? Stop, and read this
The M4 is the one that matters here, and it runs under 50 miles from Goodwick. It will usually get you onto it, and some way along, before you spot a thing. Then it's some smoke, an uneven idle and power falling away — not a clean stop. Wrongly fuelled diesels rarely give you one of those.
Take the next exit that's safe, stop there, and do not start it to move it. Long run? Anything near the under 15 miles to the closest city and you should suppose the lot — filter, pump, injectors, all of it reached by the petrol. Say that on the call, as it changes what goes in the van.
Where is Goodwick?
Goodwick is a coastal town in Pembrokeshire, situated on the north side of the haven, with a mix of terraced housing and more modern developments. Goodwick has a population of around 2920 people and is located near the villages of Harbour Village, Stop-and-Call, and Dyffryn. Goodwick sits at an elevation of 24 metres, looking out over the sea. Goodwick is close to the smallest city in the UK, St Davids, which is 14 miles away.
What happens when our engineers arrive with you in Goodwick
- We find out what was put in, how much, and if your motor has run. The answers change the work, which is why our technicians ask before pricing.
- We drain your tank of all the tainted fuel.
- Our engineers rinse your fuel lines and clean the fuel filter, so what's remaining in the fuel system isn't what started the problem.
- Priming follows, once fresh diesel is in.
- It is fired up with clean diesel in it, and our engineers check that it is running smoothly.
After that it is ready to set off. There is no need to go to a garage at any stage, because the work is all done where the car is, and when it's noticed quickly, long-term damage is very unusual.
AdBlue in a diesel tank in Goodwick is a distinct matter
The issue is not the same, though the first rule is — never crank it — if what was put in was AdBlue rather than petrol. Thinned diesel, and no protection left for your fuel system that depends on it. That is petrol. Urea dissolved in water, AdBlue, and in a diesel tank that leads to corrosion and residue.
Both are ours. There is a separate Goodwick page for AdBlue removal, with the details on it — including the reasons it frequently turns out to be the worse of the two.
Goodwick prices for a petrol-in-diesel fuel drain
Our technicians cannot put one figure on this page frankly, as this job is not one job. What moves it:
- Whether your motor has been started or driven. This is the main one.
- Wrong fuel in, against what that tank takes — that proportion.
- The kind of liquid in the tank, petrol or AdBlue.
- Access: the car's position, and whether working on it there's safe for a technician.
A firm answer instead of a range is what you get for telling us three things: the vehicle, the quantity, and whether it has run. Not time-critical, with your car at home and going nowhere? Then is fine.
Questions we get about petrol in diesel in Goodwick
Fuel drains on a Goodwick petrol station forecourt
Plenty of what our engineers do takes place nowhere else. So yes. Often, provided the site consents: another forecourt nearby, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that place is something our engineers answer there and then.
A few litres of petrol in a diesel — too much?
Litres aren't the yardstick. Proportion is, and far more than either, it counts whether anything has been run. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same query in the end: has that blend been pulled right through, or has it not?
Already driven it with petrol in your diesel? Now what?
Turn off somewhere safe, then keep it that way after you stop. Not restarting it is the single most valuable thing available to you now. Driving does shift the issue out of the tank and into your pump and injectors, yes, and it remains recoverable far more often than people fear.
Is a fuel drain going to void my warranty?
A manufacturer's warranty withstands a drain then flush done to a proper standard, which is no modification at all. What is likelier to start a disagreement is a diesel that has been run on petrol. One more good reason for your engine to stay off.
Adding two-stroke oil, then driving home
What petrol has thinned isn't restored by two-stroke oil, which is an old workaround for a distinct problem. So no. Your pump still has to cope with it, because that tank still has petrol in it after that.
Do I need a main dealer for petrol in a diesel?
You don't need one. The car is drained and cleaned wherever it is, with no need to take it to a franchised dealer.
Still with your car?
Leave it turned off.
If you have already driven the vehicle, pull in somewhere sensible, switch it off then keep it off. Cold and parked, a motor is in the best place available — and people fear this far more than the recovery rate warrants.
