Should You Worry? Petrol in a Diesel Car in Brownhills West
Not started? Then less worried than you likely feel. "Have I ruined it?" is the first thing everyone in Brownhills West asks, and the honest answer is generally no, because petrol left in a diesel tank harms nothing till it's drawn through the fuel system — by ignition priming, by your starter, or by driving. Keep it that way: leave the engine off then call Petrol in Diesel. Read on for three things: the effect petrol has inside a diesel motor, the signs of how far it has spread, and ways to make sure you never repeat it.
Your engine and petrol in a diesel: what goes on
Diesel has two tasks on its way through an engine. It lubricates to begin with, and only then does it burn. Your high-pressure pump and the injectors are designed to extremely fine tolerances, and the diesel passing through them is what stops those surfaces from grinding against one another.
Petrol does the first task poorly and the second not at all. It's runnier than diesel and removes the lubrication your fuel system rests on, and so a pump running on a petrol mix is a pump wearing itself. And petrol is made to resist igniting under compression, which is the opposite of what a diesel needs from its fuel. That is where the clattering comes from.
The shape of the issue is clear when you put those together. It's movement that causes the damage, not contact. Petrol in a tank is a fuel fault. Once the pump has been working on that petrol, a mechanical problem has started: anything shed by a pump that is wearing travels downstream to the fuel injectors with your fuel.
Brownhills West, petrol in a diesel: four situations, from mild to serious
The best case there is: filled up, not once started. The petrol is in your tank and only the tank, and the task is a drain and a flush where the car stands. This is the one scenario that can only really take place at a forecourt, as anywhere else the car has been driven to get there.
Your ignition turned on, or a brief start. Your system has been bled, and so petrol has left your tank and got to the fuel filter and the lines. Still usually simple: drain, flush, and the fuel filter sorted.
Those few miles driven were your pump labouring on fuel thinned by petrol the whole way. Tank, lines, filter, then clean fuel put through the whole system: that is this work, and the way your car was driven matters as much as the distance. The school run to Brownhills West Primary School is one matter. A run as far as Lichfield, under 10 miles away, is a very different job. So is any distance on the M6 Toll, under a mile from Brownhills West, where the motor has been running hard throughout.
Driven on till it protested — clattering, smoke, a ragged idle, a dead throttle. The motor is telling you your fuel is no longer acting like diesel. Stop on the spot — on the verge on Wilkin Road, 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 lasting damage very uncommon when a car is stopped soon.
Brownhills West drivers and that petrol in a diesel stories they hear
It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." Topping up takes out nothing; it gives you a fuller tank of the same mixture. Percentage isn't how a diesel fuel system tolerates petrol, however much that guidance assumes.
Myth: a newer diesel copes with a bit of petrol. Rather, the opposite. A newer diesel runs its fuel through more precise parts at higher pressure, which makes the lubrication matter more, not less.
"It starts, it drives, so no harm done" — the myth that trips up most people than any other. Feed diesel to a petrol engine and it normally won't run, so the motorist stops — and the harm stops with them. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, as it usually does; meanwhile your pump wears. Being able to run isn't proof of being fine.
"A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a different fault. It doesn't put back what petrol has thinned, and the petrol is still inside the tank later on.
Once your engine has run, part of that petrol sits in your filter and your lines, not that tank — and your next start pulls it straight back through the pump. So the myth "drain your tank yourself and you are sorted" doesn't stand up. Emptying petrol into a can by the roadside is also genuinely dangerous.
How it happens: petrol in a diesel
It's rarely 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 mostly will not fit a petrol car. That is how the forecourt makes it easy.
It takes place when habit and the car stop matching. A new car, a hire car or a courtesy car. Households running one of each, petrol and diesel. The pumps in a different order on a familiar forecourt. A train to catch, and a hurried fill en route to Landywood. Exactly the moment it takes place: after years of driving petrol, a driver fills a diesel Volkswagen Golf for the first time. Your hand repeats what it has always done once you add rain, a phone call or a back seat full of children.
Next time you fill up in Brownhills West: avoiding petrol in a diesel
- A green handle for unleaded and black for diesel is usual in the UK — yet not on each forecourt. Go by the label on the petrol pump, not the colour.
- The first fill in a new motor is the time to check your filler flap — on it, or on the cap, many vehicles state the fuel they take.
- Mark 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.
- Before the nozzle comes off the pump the first time you fill a hired or new car, say "diesel" out loud. Daft, perhaps, yet it works.
- Thinking about something else is when this becomes an easy mistake to make, and so tuck the phone away and keep your mind on the pump.
- Add-on devices are available for vehicles without one, and some diesels come with a filler that will not take a petrol nozzle. Useful — but a backstop at best, never a reason to stop checking the label.
- Noticing it halfway? Stop there and then. A thinner mixture results from less petrol in the tank, but your next step remains the same: don't fire it up.
Petrol already in a diesel in Brownhills West? Begin here
Short and simple, then, is the order of things. Don't turn the ignition on, and do not fire it up. The staff on the forecourt — whether at Esso itself or wherever you filled up — will usually help roll it clear of the pump if you ask. Next, 0333 366 0103. We'll ask what went in, roughly how much, and if it has been run.
Say so if it was AdBlue rather than petrol: it's a separate issue, with its own page for Brownhills West, because AdBlue brings corrosion and deposits rather than lost lubrication.
Brownhills West petrol in a diesel jobs: why one costs more than another
There is no honest single quote for this, because the four scenarios above are four separate jobs. The situation itself does most of the work of moving your cost. Two things follow that: the petrol that got in as a proportion of what that tank takes, then the place your car is in and whether a van can reach it safely.
What went in, how much, and whether it's run — three queries we ask before pricing, not after, for exactly that reason. With the replies, you get a straight figure rather than a range.
