Should You Worry? Petrol in a Diesel Car in Lynch Hill
Likely less than you are now — provided no one has started it. Petrol resting in a diesel tank does nothing to your engine until something pulls it through the system — the ignition priming your pump, the starter, or the drive on its own. So the fair answer to the first query everyone around Lynch Hill asks, "have I wrecked it?", is normally no. Leave your engine off and call Petrol in Diesel — that is how you keep it like that. Further down, you will find what petrol actually does inside a diesel, how far it may have got, and how to stop it happening to you again.
Inside the motor: what petrol in a diesel really does
On its way through an engine, diesel does two jobs. It lubricates first, and after that does it burn. Designed to very fine tolerances, the injectors and your pump depend on your diesel moving through them to stop their surfaces wearing against one another.
Of those two tasks, petrol handles the first badly and the second not at all. Being less viscous than diesel, petrol strips away the lubrication a fuel system needs, leaving a pump running on the blend wearing itself. It's equally made to resist igniting under compression — the reverse of what a diesel needs — which is why you hear the rattling.
The shape of the issue is clear once you put those together. Contact doesn't do the harm — circulation does. Where the petrol is only inside your tank, it is a fault of fuel, nothing more. After the pump has been working on that petrol, a mechanical problem has begun: whatever is shed by a pump that's wearing down is carried onward to the injectors with your fuel.
Lynch Hill, petrol in a diesel: four cases, from mild to significant
Fuelled, and never started: nothing beats it. Being at a forecourt is what makes this possible: elsewhere, the car has been driven there to begin with. With the petrol held inside your tank alone, it's drained and purged right where it stands, and nothing more is needed.
Ignition on, or started for a second. With your system primed, your lines and filter now hold petrol that has come from that tank. Normally little more than emptying, rinsing and seeing to your filter, and so still simple.
The pump now worked a few miles on weakened fuel — that is what driving it does. The work is your tank, the fuel lines, the filter and fresh fuel through the entire system, and how hard the vehicle was driven counts as much as how far. On the school run to Whitchurch Church of England Primary School, the distance is short. Very different a second time: a trip to Winchester, under 15 miles away, or any miles on the M3, under 10 miles from Lynch Hill, where the engine kept working hard.
Driven till it protested. Rattling, a ragged idle, smoke, a throttle that has gone soft. The motor is telling you the fuel is no longer acting like diesel. Stop on the spot — on the verge on Lynch Hill Park, at the kerb, down a side road — and don't move it. What goes first is still the fuel drain and flush, and that takes care of it, with permanent damage very rare if a vehicle is pulled over quickly.
Petrol in a diesel myths Lynch Hill people hear
"Top it up the rest of the way with diesel and it will be fine" — a myth. It won't. Topping up takes out nothing; it gives you a bigger tank of the same mix. The assumption 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. More precise components and higher pressure are the way a newer diesel runs its fuel, and that makes the protection matter more, not less.
This is the one that fools drivers. Myth: "If it starts and drives, there's no damage done." Feed diesel to a petrol motor and it generally won't run, and so the motorist stops — and the harm stops with them. A diesel fed petrol normally starts, idles and drives away as if nothing has happened, whilst your pump grinds. Running isn't the same as fine.
An outdated fix for a different fault lies behind this one. Myth: "Add some two-stroke oil and drive the car home." The petrol is still inside your tank afterwards, and what it has thinned isn't put back.
Myth: "Drain your tank yourself and you are sorted." After the engine has run, some of the petrol is no longer inside the tank: it's in your filter and the lines, and it goes straight back through the pump on the next start. Emptying petrol into a can at the roadside is also genuinely hazardous.
Why petrol in a diesel takes place so easily
A careless moment is seldom the cause, and no one means to do it. A diesel nozzle mostly will not go into a petrol vehicle, but the smaller petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one mistake straightforward, and only in that direction.
When habit and the car stop matching, it takes place. Hire cars, courtesy cars, and motors that are new to you. Two motors on one drive, one petrol, one diesel. A forecourt you know, but with its pumps arranged differently. Racing for a train outside Whitchurch (Hampshire) and fuelling up en route. A new-to-you diesel Skoda Octavia, its first fuelling, and a motorist used to petrol: exactly when it happens. Your hand does what it has always done once you add rain, a phone call or a back seat full of children.
Lynch Hill people: how to prevent petrol in a diesel next time
- The label is what counts, so read the petrol pump rather than the colour: in the UK unleaded handles are normally green and diesel black, yet not on each forecourt.
- In a car you don't know, look inside the flap over the filler or at the cap before your first fill: many vehicles state the fuel there.
- A coloured fob or a sticker on your diesel's key does more than any amount of meaning to remember, in a house with one of each.
- It seems silly and it does the trick: on the first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the pump.
- Thinking about something else is when this becomes an easy mistake to make, and so put your phone away then keep your mind on the pump.
- A misfuel inhibitor helps, up to a point. Some diesels have a filler built to reject a petrol nozzle, and add-on devices are available for vehicles without one. They are a safety net, not a reason to stop reading the pump.
- Noticing it halfway? Stop there and then. A thinner mixture results from less petrol inside that tank, yet the next step stays the same: do not fire it up.
Put petrol in a diesel around Lynch Hill already?
The order of things is brief, then. Never fire it up, and don't switch your ignition on. Still on the forecourt, at Whitchurch Filling Station or anywhere else? Ask the attendants to help you push the car clear of the petrol pump. Phone 0333 366 0103 next, with three answers — your fuel, the approximate quantity, and if it has run.
Say so if it was AdBlue instead of petrol: it is a different issue, with its own page for Lynch Hill, because AdBlue brings corrosion and deposits rather than lost protection.
What makes one Lynch Hill petrol in a diesel task cost more than the next
There's no fair single price for this, because the four scenarios above are four separate tasks. The scenario itself does most of the work of moving the cost. Two things follow that: the petrol that was put in as a proportion of what your tank takes, then the spot the car is in and whether a technician can reach it safely.
That is why our technicians ask three questions before costing instead of after: what was put in, how much, and if it has run. Those replies turn a range into a straight figure.
