Petrol in a Diesel Car in Georgetown: How Worried Should You Be?
Probably less than you are now — provided nobody has started the car. Until the ignition primes the pump, the starter cranks, or your vehicle is driven, petrol in a diesel tank simply waits there and does nothing. Which makes the honest reply to the first Georgetown question — "have I ruined it?" — usually no. To leave it that way, call Petrol in Diesel and leave the motor switched off. Below, you will find what petrol actually does inside a diesel, how far it might have gone, and how to stop it happening to you again.
The engine and petrol in a diesel: what goes on
Two jobs fall to diesel on its journey through a motor. It burns, and before it burns it lubricates. Very fine gaps are built into your injectors and the high-pressure pump, and just the diesel flowing through keeps those surfaces from grinding together.
The second task petrol does not do at all, and the first it does badly. It is thinner than diesel and removes the lubrication the system depends on, and so a pump running on a petrol mix is a pump wearing itself. And petrol is designed to resist igniting under compression, which is the opposite of what a diesel needs from its fuel. That's where the knocking comes from.
Together, those leave the shape of the trouble plain. The damage is done by movement, not by contact. Petrol in the tank is a fuel issue. The start of a mechanical problem is a pump that has been labouring on that petrol — and whatever a worn pump sheds moves on with your fuel to the injectors downstream.
How bad is petrol in a diesel? Four situations our technicians see around Georgetown
The best case there is: filled up, not once started. On a forecourt, and truly only there, that petrol is still confined to the tank — because anywhere else your car was driven to reach it. The task is emptying and rinsing on the spot.
Started for a second, or just the ignition on. Once primed, your system has drawn petrol out of that tank as far as the filter and your lines. Drain, flush, deal with the fuel filter: still usually straightforward.
Driven a couple of miles. Now the pump has spent those miles labouring on weakened fuel. The work is the tank, the lines, the fuel filter and clean fuel through the entire system, and how hard the vehicle was driven counts as much as how far. Driving the children to the local primary school is one sort of trip. A run as far as Newport, under 25 miles away, is a very different job. So is any distance on the M4, under 25 miles from Georgetown, where your engine has been running hard the whole time.
Rattling, a ragged idle, smoke, a throttle gone soft: driven until it complained. The fuel isn't behaving like diesel any more, and your motor is saying so. Pull up wherever you are — the verge on Mount Pleasant View, a lay-by, a side street — then leave it there. What goes first is still the fuel drain and flush-through, and that sorts it out, with lasting damage very rare if a vehicle is stopped soon.
What Georgetown motorists get told about petrol in a diesel — and the stories in it
Myth: topping up to full with diesel makes it fine. It does not. Nothing comes out when you top up — your tank simply holds more of the same mixture. The idea behind that advice — that diesel fuel systems tolerate petrol by percentage — is wrong.
Myth: "A modern diesel can cope with a bit of petrol." If anything, the reverse. A newer diesel sends its fuel through finer parts at higher pressure, which makes the lubrication matter more, not less.
One myth that catches motorists off guard: if it starts and drives, it must be unharmed. Any petrol motor fed diesel normally won't run, so the motorist stops and the harm stops with them. A diesel fed petrol usually starts, idles and drives away as if nothing has happened, whilst your pump grinds. Being able to run is not the same as being fine.
Myth: a two-stroke additive lets you to drive home. It was an old fix, meant for another problem. It does not put back what petrol has thinned, and that petrol is still in that tank later.
Myth: "Drain your tank yourself and you are sorted." Once the engine has run, some of that petrol is no longer in your tank: it is in the fuel filter and your lines, and it goes straight back through the pump at the next start. Besides, petrol drained into a can by the road is genuinely dangerous.
Why petrol in a diesel takes place so easily
Nobody does it on purpose, and it's rarely carelessness. The forecourt makes it easy: the petrol nozzle is the smaller of the two, and it slides into a diesel filler with almost no resistance, whilst a diesel nozzle generally will not go into a petrol vehicle at all. So the slip runs one way.
When habit and the vehicle stop matching, it takes place. Courtesy car, hire car, or a car that is new. A household with one petrol and one diesel on the drive. Your normal forecourt, its pumps now in a different order. A train to catch, and a hurried fill on the way to Ebbw Vale Town. Years of petrol motors behind you, a diesel Volkswagen Golf in front of you on the forecourt for its first tank — that's when. The hand does what it has always done when you add rain, a phone call or a back seat full of kids.
Next time you fill up in Georgetown: preventing petrol in a diesel
- A green handle for unleaded and black for diesel is usual in the UK — yet not on each forecourt. Trust the label on the petrol pump, not the colour.
- Many cars state the fuel type inside the filler flap or on the cap, so check there on your first fill in a vehicle you don't know.
- Label the key. In a home with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember.
- Say it before you lift it. On your first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the petrol pump. It sounds daft and it does the trick.
- Mistakes like this are easy to make while your mind is on something else, and so the phone goes away.
- Some diesels have a filler designed to refuse a petrol nozzle, and devices you can add are available for vehicles without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop reading the petrol pump.
- Less petrol means a weaker blend, so stop as soon as you realise — while remembering that the next stage is unchanged. It's still not to crank it.
Petrol already in a diesel in Georgetown? Begin here
Short and simple, then, is the order of things. Leave it unstarted, with your ignition off as well. Yet at the forecourt, at Gulf or anywhere else? Ask the attendants to help you push it clear of the pump. Next, 0333 366 0103. We'll ask what got in, about how much, and if it has been run.
Say so if it was AdBlue rather than petrol: it is a different fault, with its own page for Georgetown, since AdBlue brings corrosion and deposits instead of lost lubrication.
What makes one Georgetown petrol in a diesel task cost more than the next
There's no honest single price for this, since the four scenarios above are four different tasks. Which of them you are in is mostly what moves your cost. Where the car is matters too, and whether a van can safely reach it, after the ratio of petrol to what your tank takes.
Three questions come first, before any quote, rather than after — what went in, how much, has it run — and that is the reason. Those answers are what turn a range into one firm number.
