Petrol in a Diesel Car in Bilson Green: How Worried Should You Be?
Unstarted? Then less anxious than you probably are. Petrol sitting in a diesel tank does nothing to your engine until something pulls it through the system — your ignition priming the pump, the starter, or driving on its own. So the honest answer to the first question anyone around Bilson Green asks, "have I ruined it?", is usually no. Keep it like that: leave the engine off then call Petrol in Diesel. Read on for three things: the effect petrol has inside a diesel motor, the clues of how far it has got, and the way to make sure you don't repeat it.
What petrol in a diesel does to the engine
Passing through an engine, diesel does two jobs at the same time. Before it burns, it protects — and then it combusts. The high-pressure pump and the fuel injectors are built to very fine clearances, and the diesel passing through them is what keeps those surfaces from wearing down against one another.
The second task petrol does not do at all, and the first it does poorly. The rattling comes from petrol being made not to ignite when compressed, which is exactly the opposite of what a diesel needs. On top of that it is runnier than diesel, it strips away the lubrication the fuel system depends on, and any pump working on such a blend is wearing itself.
Together, those make the shape of the trouble clear. Not contact but movement is what does the damage. Petrol in a tank is a fuel issue. After the pump has been working on that petrol, a mechanical problem has begun: anything shed by a pump that's grinding travels onward to your injectors with your fuel.
Petrol in a diesel in Bilson Green: how bad is it? Four cases
Fuelled but never started — as good as it gets. That petrol is inside the tank and just that tank, and the job is a drain and a flush where the car sits. This is the one scenario that can only really happen at a forecourt, since anywhere else your car has been driven to get there.
Started for a moment, or just your ignition on. Petrol has left your tank and got to the fuel filter and the lines, since the fuel system has been bled. Still generally easy: drain, flush, and your filter seen to.
The pump now spent a couple of miles on diluted fuel — that is what driving it meant. The work is that tank, the fuel lines, your filter and fresh fuel through the entire system, and how hard the car was driven matters as much as how far. Driving the children to St White's Primary School is one kind of trip. Very different a second time: a trip to Gloucester, under 15 miles away, or some distance on the M50, under 10 miles from Bilson Green, where the engine kept running hard.
Driven on till it complained — clattering, smoke, a ragged idle, a dead throttle. What you are hearing is the engine reporting fuel that no longer acts like diesel. Leave it where it has stopped: a lay-by, a side street, the verge on Forest Vale Road. What goes first is still the drain and flush, and that deals with it, with lasting damage very unusual when a vehicle is stopped early.
Stories Bilson Green people hear about petrol in a diesel
Myth: "Fill it the rest of the way with diesel and it'll be fine." It will not. Nothing is removed when you top up — your tank just holds more of the same blend. Percentage is not how a diesel fuel system copes with petrol, however much that guidance presumes.
Myth: "A current diesel can cope with a bit of petrol." If anything, the opposite. Protection counts more on modern diesels, not less, since their fuel passes through finer components at higher pressure.
"It starts, it drives, so no harm done" — the myth that catches more drivers than any other. Diesel in a petrol motor usually means a motor that will not run: the driver stops, and so does the damage. Nothing looks to have happened when a diesel fed petrol fires up, ticks over and drives away, which it usually does; meanwhile your pump wears. Running isn't the same as fine.
"A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a distinct fault. It doesn't put back what petrol has thinned, and the petrol is still in the tank afterwards.
Myth: "Drain the tank yourself and you are sorted." Once the motor has run, some of the petrol is no longer in that tank: it's in the filter and the fuel lines, and it goes right back through your pump on your next start. Clearing petrol into a can at the roadside is also truly dangerous.
How petrol ends up: petrol in a diesel
It's seldom carelessness, and nobody does it on purpose. One way only, because of the nozzles: the narrower petrol one slips inside a diesel filler with almost no resistance, whereas the diesel one mostly will not fit a petrol vehicle. That is how the forecourt makes it simple.
When routine and the vehicle stop matching, it occurs. Courtesy car, hire car, or a motor that's brand new. A household with one petrol and one diesel on the drive. A forecourt you know, but with its pumps arranged differently. Fuelling up in a hurry en route to Lydney, with a train to catch. A new-to-you diesel Volkswagen Golf, its first fuelling, and a motorist used to petrol: exactly when it happens. The hand repeats what it has always done when you add rain, a phone call or a back seat full of children.
Next time you fill up in Bilson Green: avoiding petrol in a diesel
- Green for unleaded and black for diesel is usual in the UK — yet not on every forecourt. Trust the label on the pump, not the colour.
- Check your filler flap. Many vehicles state the fuel inside the flap or on the cap. Look at it on the first fill in any motor you do not know.
- Label your key. In a household with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of intending to remember.
- Say it before you lift it. On your first fill in a new or hired car, say "diesel" aloud before you lift the nozzle off the pump. It sounds daft and it does the trick.
- Put your phone away. This is an easy mistake to make while you are thinking about something else.
- Up to a point, a misfuel inhibitor helps: some diesels come with a filler designed to block a petrol nozzle, and add-on devices exist for the rest. Treat it as a safety net, then keep checking the petrol pump.
- The moment you notice, stop: less petrol in your tank means a weaker blend. What to do next doesn't change, though — still don't fire it up.
Bilson Green: already put petrol in a diesel?
Then the order of things is short. Do not fire it up, and do not switch the ignition on. Ask the staff to help you push it clear of the pump if you're still at the forecourt, whether that is Shire Fuels or anywhere else. Then ring 0333 366 0103 and tell us what went in, roughly how much, and if it's run.
Corrosion and deposits are the issue with AdBlue, whereas petrol means lost lubrication. So if it was AdBlue, say so — and see its own Bilson Green page.
What makes one Bilson Green petrol in a diesel job cost more than the next
An honest single quote doesn't exist here: four scenarios, four separate jobs. Which of them you are in is mostly what moves the cost. Where the car is matters too, and whether our van can safely get to it, after the proportion of petrol to what the tank holds.
That's why our engineers ask three questions before quoting instead of after: what went in, how much, and if it has run. Those replies change a range into a straight figure.
