How Worried Should You Be? Petrol in a Diesel Car in Orsett
Not started? Then less anxious than you probably are. "Have I wrecked it?" is the first question anyone in Orsett asks, and the honest answer is normally no, since petrol resting in a diesel tank harms nothing till it is dragged through your fuel system — by ignition priming, by your starter, or by being driven. Leave your motor off and call Petrol in Diesel — that keeps it that way. Keep reading for three things: the effect petrol has inside a diesel engine, the signs of how far it has spread, and ways to make sure you don't do it again.
Inside the motor: what petrol in a diesel really does
Diesel does two tasks on its way through an engine. It protects to begin with, and only then does it burn. Very fine tolerances are built into your injectors and your high-pressure pump, and only the diesel running through stops their surfaces grinding together.
Poorly at the first, not at all at the second: that's petrol. It is runnier than diesel and removes the protection your fuel system rests on, and so a pump running on a petrol mixture is a pump wearing itself. And petrol is made to resist igniting under compression, which is the reverse of what a diesel needs from its fuel. That is where the clattering comes from.
Taken together, they show what shape the trouble has. Not contact but movement is what does the damage. All a tank with petrol in it amounts to is a fuel fault. A pump that has been labouring on that petrol is the start of a mechanical one, and whatever a worn pump sheds moves on with the fuel to your injectors further on.
How bad is petrol in a diesel? Four situations we see around Orsett
Filled up, and never started: no case is better. The petrol is inside your tank and just that tank, and the job is a drain and a flush where the car stands. This is the one scenario that can only really take place on a forecourt, since anywhere else your car has been driven to get there.
Started for a moment, or just your ignition on. With your system primed, the lines and filter now hold petrol that has come from your tank. Drain, flush, deal with the fuel filter: still usually straightforward.
Driven a couple of miles. Now the pump has spent these miles running on thinned fuel. How hard the car was driven counts as much as how far, and the work takes in that tank, the fuel lines, the filter and fresh fuel through the entire circuit. The school run to Orsett Church of England Primary School is one thing. Any mileage on the M25, under 5 miles from Orsett, means your engine has worked hard throughout, and a run to Southend-on-Sea, under 15 miles away, makes a very different task as well.
It complained, and only then stopped: smoke, clattering, a throttle gone soft, an idle gone lumpy. The fuel is not behaving like diesel any more, and your motor is telling you. Pull up wherever you are — the verge on Rectory Road, a lay-by, a side street — then leave the car where it is. Lasting damage is very rare if a vehicle is pulled over soon, and the drain and flush that still come first take care of it.
Petrol in a diesel stories Orsett motorists hear
"Top it up the rest of the way with diesel and it'll be fine" — a myth. It won't. A fuller tank of the same mixture is all you get, since topping up removes nothing. That guidance supposes a diesel fuel system tolerates petrol by percentage. It does not.
Myth: "A current diesel can cope with a bit of petrol." If anything, the opposite. A newer diesel runs its fuel through finer parts at higher pressure, which makes the protection count more, not less.
The myth that catches people off guard: if it starts and drives, it must be unharmed. The motorist of a petrol motor fed diesel normally stops, because it will not run, and the harm stops there. Whilst the pump wears, a diesel fed petrol usually starts, ticks over and drives away as though nothing has happened. Being able to run is not proof of being fine.
Myth: a two-stroke additive makes it safe to drive home. It is an old fix, meant for another problem. What petrol has weakened stays weakened, and the petrol remains in the tank anyway.
The next start draws petrol back round your pump out of the fuel lines and your filter, where some of that sits once your engine has run. That's why draining your tank yourself doesn't leave you sorted — a myth. Emptying petrol into a can by the kerbside is also truly dangerous.
How petrol ends up: petrol in a diesel
Nobody does it on purpose, and it is seldom carelessness. A diesel nozzle generally won't fit a petrol vehicle, but the smaller petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake simple, and only in one direction.
It happens when habit and the car stop matching. A new car, a hire car or a courtesy car. Two cars on one drive, one petrol, one diesel. The pumps in a different order on a familiar forecourt. Racing for a train at Stanford-Le-Hope and filling up en route. Exactly the moment it happens: after years of driving petrol, a driver fills a diesel Volkswagen Passat for the first time. With rain, a call coming in, or a car full of children to deal with, your hand just does what it has always done.
Orsett drivers: how to prevent petrol in a diesel next time
- A green handle for unleaded and black for diesel is usual in the UK — but not on each forecourt. Go by the label on the pump, not the colour.
- Many motors state the fuel inside your filler flap or on the cap, and so check it on the first fill in a motor you do not know.
- A coloured fob or a sticker on your diesel's key achieves more than any amount of meaning to remember, in a house with one of each.
- It sounds silly and it works: on the first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the pump.
- Mistakes like this are easy to make while your mind is on something else, so the phone goes away.
- Add-on devices exist for vehicles without one, and some diesels are built with a filler that won't take a petrol nozzle. Helpful — but a safety net at best, never a reason to stop checking the label.
- Less petrol makes a thinner mix, and so stop the moment you notice — though remembering that the next stage is unchanged. It's still not to crank it.
Orsett: already put petrol in a diesel?
Then the order of things is short. Do not crank it, and don't turn your ignition on. The attendants on the forecourt — whether at BP itself or wherever you filled up — will normally help roll it away from the pump if you ask. Ring 0333 366 0103 next, with three facts — your fuel, the rough quantity, and whether it has run.
Corrosion and deposits are the trouble with AdBlue, whereas petrol brings lost lubrication. So if it was AdBlue, say so — and read its own Orsett page.
Orsett petrol in a diesel tasks: why one costs more than another
Four separate tasks lie behind the four situations above — which is why there's no honest single quote. The situation itself does most of the work of moving your cost. After that it is the ratio — how much petrol got in against how much the tank takes — and then where your car is and whether a technician can get to it safely.
That's why our engineers ask three questions before pricing instead of after: what was put in, how much, and whether it has run. With those answers, you get a straight figure instead of a range.
