Petrol in a Diesel Car in Brookfield: How Worried Should You Be?
Likely less than you already are — provided no one has started the car. Everyone in Brookfield starts with "have I ruined it?", and the fair answer is usually no: petrol left inside the tank of a diesel stays harmless until priming, cranking or driving pulls it into your fuel system. Keep it that way: leave your motor off and ring Petrol in Diesel. Keep reading for three things: the effect petrol has inside a diesel motor, the signs of how far it has spread, and the way to make sure you don't repeat it.
What petrol in a diesel does to the engine
Two tasks fall to diesel on its journey round a motor. It combusts, and before it burns it protects. Designed to extremely fine clearances, the fuel injectors and your pump rely on the diesel moving through them to stop their surfaces wearing against one another.
Of these two tasks, petrol handles the first badly and the second not at all. A pump working on a petrol mix is wearing itself out, because petrol is thinner than diesel and takes away the lubrication your fuel system depends on. Petrol is also designed to resist igniting under compression — the reverse of what a diesel needs from its fuel — and that's where the rattling starts.
Together, those make the shape of the issue clear. Contact doesn't do the damage — circulation does. Where the petrol is only inside your tank, it's a problem of fuel, nothing more. A pump that has been running on that petrol is the beginning of a mechanical one, and whatever a worn pump sheds travels on with the fuel to the injectors downstream.
Petrol in a diesel in Brookfield: how serious is it? Four cases
Fuelled, and not started: no case is better. The petrol is inside that tank and just the tank, and the task is a drain and a flush where the vehicle stands. This is the one scenario that can only truly happen at a forecourt, since anywhere else your car has been driven to get there.
Ignition on, or started for a second. With the system primed, the fuel lines and filter now hold petrol that came from the tank. That's usually still an easy task — a drain, a flush, and the filter seen to.
Your pump now spent a couple of miles on thinned fuel — that's what driving the car does. The work is the tank, the fuel lines, your filter and clean fuel through the whole circuit, and how hard your car was driven counts as much as how far. Short trips, such as the school run to Ashford Oaks Community Primary School, are one thing. Getting as far as Canterbury, under 15 miles away, makes a very different task — as does any mileage on the M20, under 3 miles from Brookfield, with the engine working hard all the way.
It complained, and only then stopped: smoke, clattering, a throttle gone soft, an idle gone lumpy. The fuel is not acting like diesel any more, and the engine is telling you. Pull up on the spot — on the verge on Allen Field, at the kerb, down a side road — and don't move it again. A car pulled over early very seldom has long-term damage, as the drain and the flush, which still go first, sort it out.
Petrol in a diesel myths Brookfield people hear
Myth: "Fill it the rest of the way with diesel and it will be fine." It will not. Nothing comes out when you top up — your tank just holds more of the same blend. Percentage is not how a diesel fuel system copes with petrol, whatever that advice presumes.
Myth: "A current diesel can cope with a bit of petrol." If anything, the opposite. More precise parts and higher pressure are how a current diesel runs its fuel, and that makes the protection matter more, not less.
The myth that catches drivers 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 damage stops there. While your pump wears, a diesel fed petrol usually starts, ticks over and drives away as if nothing has happened. Being able to run isn't proof of being fine.
An old workaround for a different problem lies behind this one. Myth: "Add some two-stroke oil and drive the vehicle home." It doesn't put back what petrol has diluted, and that petrol is still in your tank afterwards.
If the motor has been run, part of the petrol sits in your filter and the fuel lines, not that tank — and the next start pulls it straight back through your pump. So the myth "drain the tank yourself and you are sorted" doesn't stand up. Emptying petrol into a can at the kerbside is also genuinely dangerous.
Petrol in a diesel: how does it happen?
It is seldom carelessness, and nobody does it on purpose. One way only, since of the nozzles: the slimmer petrol one slips inside a diesel filler with almost no resistance, whereas the diesel one generally won't fit a petrol vehicle. That is how the forecourt makes it easy.
When routine and the car stop matching, it occurs. Any car that's new to you — a hire car, on loan as a courtesy car, or brand new. Two cars on one drive, one petrol, one diesel. A forecourt you know, but with its pumps arranged differently. A train to catch, and a hurried fill en route to Ashford International. The first fill-up in a diesel Renault Clio after years of driving petrol is exactly the moment it occurs. Your hand does what it has always done when you add rain, a phone call or a back seat full of children.
How to avoid petrol in a diesel on your next fill-up in Brookfield
- Not every forecourt in the UK follows green for unleaded and black for diesel, though most generally do. Check the pump's label; the colour is just a hint.
- Many vehicles state the fuel inside your filler flap or on the cap, and so check there on the first fill in a vehicle you don't know.
- Good intentions do less than a sticker or a fob in a vivid colour on your diesel's key when a home has one of each. So label it.
- "Diesel", out loud, before you lift the nozzle — each time a new or hired car needs its first tank. It seems daft. It works.
- While you're thinking about something else, this is an easy mistake to make — so put your phone away.
- Some diesels come with 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 backstop, not a reason to stop checking the pump.
- Stop as soon as you notice. Less petrol in your tank means a thinner mix. It does not change what to do next, which is still not to crank it.
Brookfield: already put petrol in a diesel?
Then, there is just a short order of things. Do not crank it, and don't turn the ignition on. If you are still on the forecourt — BP or anywhere else — ask the attendants to help you push it away from the pump. Next, 0333 366 0103. We will ask what got in, roughly how much, and if it's been run.
AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost lubrication, make it a different problem — Brookfield has a page just for it.
What makes one Brookfield petrol in a diesel job cost more than the next
There is no honest single quote for this, because the four scenarios above are four different jobs. Which of them you are in is chiefly what shifts the cost. Where your car is matters too, and whether a technician can safely get to it, after the ratio of petrol to what the tank takes.
That's why our technicians ask three questions before pricing rather than after: what was put in, how much, and whether it has run. A range becomes a straight figure when those replies are in.
