Should You Worry? Petrol in a Diesel Car in Egstow
Far less than you probably are, if it hasn't been started. Petrol resting in a diesel tank does nothing to your motor until something draws it through the system — your ignition priming the pump, your starter, or the drive itself. So the fair answer to the first question everyone around Egstow asks, "have I ruined it?", is generally no. To leave the car that way, call Petrol in Diesel then leave your motor alone. The rest of this page explains what petrol really does to a diesel, how to judge how far it has got, and how to make sure it does not happen to you again.
What petrol in a diesel does to the engine
On its way through a motor, diesel has two jobs. It protects to begin with, and after that does it burn. What stops the surfaces inside your high-pressure pump and your injectors from wearing down against one another is your diesel flowing through them — they're designed to extremely fine clearances.
The second job petrol doesn't do at all, and the first it does poorly. Being less viscous than diesel, petrol strips away the lubrication a fuel system needs, leaving a pump on that mixture to wear itself. It is equally made to resist igniting under compression — the reverse of what a diesel needs — which is why you hear the rattling.
Together, those leave the shape of the issue clear. Contact does not do the damage — movement does. Petrol in a tank is a fuel problem. The beginning of a mechanical problem is a pump that has been running on that petrol — and whatever a worn pump sheds travels on with the fuel to the injectors beyond it.
Petrol in a diesel in Egstow: how bad is it? Four cases
Fuelled up, not once started. The best case there can be. Being on a forecourt is what makes this the case: elsewhere, the vehicle has been driven there to begin with. With that petrol kept inside that tank alone, it is cleared and rinsed on the spot, and nothing more is needed.
Ignition on, or started for a moment. Your system has been bled, and so petrol has left that tank and got to the fuel filter and the lines. Usually little more than draining, flushing and sorting the filter, so still easy.
Those few miles on the road were the pump labouring on fuel weakened by petrol throughout. Tank, lines, filter, then fresh fuel put through the entire system: that is this work, and the way your car was driven counts as much as the distance. The school run to Sharley Park Community Primary School is one thing. Very different once more: a trip to Sheffield, under 15 miles away, or some distance on the M1, under 5 miles from Egstow, where the motor kept labouring hard.
It protested, and only then stopped: smoke, clattering, a throttle gone soft, an idle gone ragged. The fuel isn't acting like diesel any more, and the motor is telling you. Whether it is the verge on Furnace Hill Road, a lay-by or a side road, stop where you are then leave it. A vehicle stopped quickly very rarely has lasting damage, since the drain and the flush, which still go first, take care of it.
What Egstow motorists get told about petrol in a diesel — and the stories in it
Myth: "Fill it the rest of the way with diesel and it will be fine." It will not. Topping up takes out nothing; it gives you a bigger tank of the same mix. That advice supposes a diesel fuel system handles petrol by percentage. It does not.
Not so: a modern diesel copes with a bit of petrol. If anything, the opposite. A current diesel runs its fuel through smaller components at higher pressure, which makes the lubrication matter more, not less.
One myth that catches drivers off guard: if it starts and drives, it must be unharmed. The motorist of a petrol engine fed diesel normally has no choice but to stop, because it will not run, and the harm stops with them. A diesel fed petrol generally starts, idles and drives away as if nothing has happened, while your pump wears. Being able to run isn't proof of being fine.
Not so: a two-stroke additive lets you to drive home. It is an old fix, meant for another problem. It doesn't put back what petrol has diluted, and that petrol is still inside that tank later.
The next start sends petrol back round the pump from your lines and the fuel filter, where some of it sits once your engine has been run. That is why a DIY tank drain doesn't sort it — a myth. Also, a can of petrol filled at the roadside is genuinely hazardous.
How does petrol in a diesel occur?
On purpose? Never. Through carelessness? Rarely, if ever. A diesel nozzle mostly will not go into a petrol car, yet the slimmer petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one error simple, and only in one direction.
When habit and the car stop matching, it happens. A motor that is new to you — hired, on loan as a courtesy car, or just bought. One petrol and one diesel on the driveway of the same household. Your ordinary forecourt, its pumps now in a different order. A hurried fill en route to Chesterfield with a train to catch. Precisely the moment it occurs: after years of driving petrol, someone fills a diesel Renault Megane for the first time. Throw in a back seat full of kids, a phone call or rain, and habit wins.
How to avoid petrol in a diesel at your next fill-up around Egstow
- Check the petrol pump, not the colour. In the UK unleaded handles are normally green and diesel black, yet not on every forecourt. The label is what matters.
- In a vehicle you don't know, look inside the flap over the filler or at the cap before the first fill: plenty of vehicles print the fuel type there.
- A coloured fob or a sticker on your diesel's key does more than any amount of intending to remember, for a home with one of each.
- Before the nozzle comes off the pump the first time you fill a hired or new motor, say "diesel" aloud. Silly, perhaps, yet it works.
- Thinking about something else is when this becomes an easy mistake to make, and so tuck your phone away then keep your mind on the petrol pump.
- A misfuel inhibitor helps, up to a point. Some diesels have a filler built to block a petrol nozzle, and add-on devices are available for motors without one. They are a backstop, not a reason to stop checking the petrol pump.
- As soon as you notice, stop: less petrol inside the tank means a thinner blend. What to do next does not change, though — still do not crank it.
Put petrol in a diesel in Egstow already?
The order of things is brief, then. Never start the vehicle, and do not switch the ignition on. The attendants at the forecourt — whether at Tesco itself or wherever you filled up — will usually help roll it clear of the pump if you ask. Then call 0333 366 0103 and tell us what got in, about how much, and if it's run.
Say so if it was AdBlue rather than petrol: it's a separate issue, with its own page for Egstow, since AdBlue brings corrosion and deposits rather than lost lubrication.
Egstow petrol in a diesel tasks: why one costs more than another
Four different tasks sit behind the four scenarios above — which is why there's no fair single quote. What moves your cost is mostly which of them you are in. Two things follow that: the petrol that got in as a proportion of what your tank takes, then the place the vehicle is in and whether a van can get to it safely.
Before any quote, not after, come three questions: your fuel that was put in, the volume, and if it's run. That's why. A range becomes a straight figure when the replies are in.
