How Worried Should You Be? Petrol in a Diesel Car in Dolcliffe Common
Likely less than you already are — as long as no one has started the vehicle. Until the ignition primes your pump, the starter cranks, or the vehicle is driven, petrol in a diesel tank just waits there and does no harm. Which makes the truthful reply to that first Dolcliffe Common query — "have I ruined it?" — normally no. Petrol in Diesel is who to phone, with the engine kept off, and so it remains that way. What petrol actually does to a diesel, how to gauge how far it has gone, and how to keep it from happening a second time: that's the rest of this page.
The motor and petrol in a diesel: what happens
Diesel does two jobs on its way through a motor. Lubricating comes before burning; it does both. What stops the surfaces inside the high-pressure fuel pump and your injectors from grinding against one another is the diesel passing through them — they are designed to very fine clearances.
Petrol does the first job badly and the second not at all. A pump working on a petrol blend is wearing itself out, because petrol is runnier than diesel and strips out the lubrication your fuel system depends on. Petrol is also designed to resist igniting under compression — the opposite of what a diesel wants from its fuel — and that is where the knocking comes.
Put these together and the shape of the trouble is plain. Contact doesn't do the harm — movement does. All a tank with petrol in it amounts to is a fuel issue. The start of a mechanical one is a pump that has been working on that petrol — and whatever a worn pump sheds moves on with your fuel to the fuel injectors downstream.
Petrol in a diesel around Dolcliffe Common: how serious is it? Four situations
Fuelled up, not once started. The best case there is. Just that tank has petrol in it, and so the job is draining the tank and flushing the system where your car sits. This scenario can only really take place on a forecourt: anywhere else, the vehicle got there by being driven.
Your ignition switched on, or a brief start. With your system primed, the fuel lines and filter already contain petrol that came from your tank. Normally nothing more than draining, flushing and sorting the filter, so still straightforward.
Driven a few miles. Now the pump has spent those miles working on diluted fuel. Mileage is only half of it; how hard it was driven matters just as much. Either way the work includes your tank, your lines, your filter and fresh fuel through the whole circuit. Short trips, such as the school run to Montagu Academy, are one thing. Very different a second time: a trip to Doncaster, under 10 miles away, or any mileage on the M18, under 5 miles from Dolcliffe Common, where your engine never stopped labouring hard.
Clattering, a ragged idle, smoke, a throttle gone soft: driven till it complained. The engine is telling you your fuel is no longer acting like diesel. Pull up on the spot — on the verge on West View Road, at the kerb, down a side road — and don't move it. The fuel drain and flush still go first, and they deal with it: when a car is pulled over quickly, lasting damage is very unusual.
What Dolcliffe Common people get told about petrol in a diesel — and the myths in it
It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." Nothing is removed by topping up — you are left with a bigger tank, still the same mix. Percentage is not how a diesel fuel system tolerates petrol, however much that advice supposes.
Myth: a newer diesel copes with a bit of petrol. Rather, the reverse. At higher pressure, through finer components: that is how a modern diesel handles its fuel, and so the lubrication counts for more, not less.
Myth: "If it starts and drives, there's no damage done." This is the one that fools motorists. Diesel in a petrol motor normally means a motor that won't run: the motorist stops, and so does the damage. A diesel fed petrol generally starts, ticks over and drives away as though nothing has happened, whilst your pump grinds. Running isn't the same as fine.
Not so: a two-stroke additive lets you to drive home. It was an old fix, meant for another problem. What petrol has thinned stays thinned, and the petrol remains inside your tank regardless.
"Drain it yourself and you are sorted" — a myth, since after it's been running some petrol lies in your filter and lines, waiting to go right back through your pump at your next start. It is also truly dangerous to drain petrol into a can by the roadside.
Why petrol in a diesel happens at all
Nobody does it on purpose, and it's seldom carelessness. A diesel nozzle generally won't fit a petrol motor, yet the narrower petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one mistake easy, and just in that direction.
It occurs when routine and your car stop matching. Hire cars, courtesy cars, and cars that are new to you. One petrol and one diesel on the driveway of the same household. A forecourt you know, only with its pumps laid out differently. Fuelling up in a hurry en route to Mexborough, with a train to catch. Years of petrol cars behind you, a diesel Volkswagen Golf in front of you on the forecourt for its first tank — that is when. With rain, a call coming in, or children to deal with, the hand simply does what it has always done.
Preventing petrol in a diesel next time you fill up around Dolcliffe Common
- The label is what counts, and so check the petrol pump rather than the colour: in the UK unleaded handles are usually green and diesel black, but not on each forecourt.
- Many vehicles state the fuel type inside the filler flap or on the cap, and so check it on the first fill in any motor you don't know.
- Mark the 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 meaning to remember.
- It seems silly and it works: on the first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the petrol pump.
- Thinking about something else is when this becomes an easy mistake to make, so tuck the phone away then keep your mind on the pump.
- Some diesels come with a filler designed to refuse a petrol nozzle, and devices you can add exist for cars without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop reading the pump.
- Stop as soon as you realise. Less petrol in the tank means a thinner mixture. It doesn't change what to do next, which is still not to fire it up.
Put petrol in a diesel around Dolcliffe Common already?
Short and simple, then, is the order of things. Starting it is out, and so is switching on the ignition. If you're still at the forecourt — JET or anywhere else — ask the staff to help you push the vehicle clear of the pump. Ring 0333 366 0103 next, with three answers — your fuel, the approximate quantity, and if it has run.
AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost lubrication, make it a different issue — Dolcliffe Common has a page just for it.
One petrol in a diesel job in Dolcliffe Common costs more than another. Why?
Four different jobs sit behind the four situations above — which is why there's no fair single price. Chiefly, the cost shifts with which situation you're in. The ratio counts next, meaning how much of the tank is petrol, and then the location of the car and whether getting to it is safe for our van.
Three queries come first, before any quote, rather than after — what got in, how much, has it run — and this is the reason. A range becomes a straight figure once the answers are in.
