How Worried Should You Be? Petrol in a Diesel Car in Newlands
Not started? Then less anxious than you probably feel. Petrol sitting in a diesel tank does nothing to the engine till something pulls it through the fuel system — the ignition priming your pump, your starter, or the drive on its own. So the fair answer to the first question anyone in Newlands asks, "have I wrecked it?", is normally no. Petrol in Diesel is who to ring, with the engine kept off, and so it remains that way. The rest of this page explains what petrol actually does to a diesel, how to judge how far it has got, and how to make sure it does not happen to you a second time.
Inside your engine: what petrol in a diesel really does
On its way through an engine, diesel does two jobs. It ignites, and before it ignites it protects. Made to very fine tolerances, the fuel injectors and your pump rely on your diesel moving through them to stop their surfaces wearing against one another.
The second job petrol does not do at all, and the first it does poorly. A pump running on a petrol mix 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 needs from its fuel — and that's where the clattering starts.
The shape of the trouble is plain when you put those together. Contact doesn't do the damage — movement does. Where the petrol is only inside that tank, it is a fault 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 moves on with the fuel to the fuel injectors downstream.
Newlands, petrol in a diesel: four situations, from mild to major
Filled up, and never started: no case is better. Just that tank has petrol in it, and so the job is draining that tank and purging the fuel system where the car stands. This scenario can only really happen on a forecourt: anywhere else, the car got there by being driven.
A brief spell of running, or merely your ignition on. With your system primed, the lines and filter already contain petrol that came from that tank. Still generally straightforward: drain, flush, and your filter seen to.
Driven a couple of miles. Now the pump has spent these miles labouring on thinned fuel. The work is the tank, the fuel lines, the fuel filter and fresh fuel through the whole circuit, and how hard the vehicle was driven counts as much as how far. Short trips, such as the school run to St Peter's Catholic Primary School - a Catholic voluntary academy, are one thing. Any miles on the Petuaria Way, under 50 miles from Newlands, means the engine working hard throughout, and a run to York, under 50 miles away, makes a very different job as well.
Driven on until it protested — knocking, smoke, a lumpy idle, a soft throttle. That is your motor telling you its fuel has stopped behaving like diesel. Leave it wherever it has stopped: a lay-by, a side street, the verge on Cross Lane. Lasting damage is very unusual when a vehicle is pulled over quickly, and the drain and flush that still come first sort it out.
Petrol in a diesel myths Newlands drivers hear
"Top it up the rest of the way with diesel and it will be fine" — a myth. It will not. Nothing is removed by topping up — you are left with a bigger tank, still the same mix. That advice assumes a diesel fuel system tolerates petrol by percentage. It doesn't.
Not so: a current diesel copes with a bit of petrol. If anything, the reverse. A newer diesel sends its fuel through finer components at higher pressure, which makes the lubrication count more, not less.
This is the one that fools drivers. Myth: "If it starts and drives, there is no damage done." Feed diesel to a petrol engine and it usually will not run, so the motorist stops — and the damage stops with them. While the pump grinds, a diesel fed petrol usually starts, ticks over and drives away as though nothing has happened. Being able to run isn't the same as being fine.
Myth: "Add some two-stroke oil and drive it home." It's an old workaround for a distinct problem. What petrol has weakened stays thinned, and the petrol remains inside your tank anyway.
Myth: "Drain your tank yourself and you are sorted." After the motor has been run, some of that petrol is no longer inside the tank: it is in the fuel filter and the lines, and it goes right back through the pump at the next start. It is also genuinely risky to drain petrol into a can by the kerbside.
How does petrol in a diesel happen?
It is rarely carelessness, and nobody does it on purpose. A diesel nozzle generally will not fit a petrol car, but the narrower petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake simple, and only in one direction.
The moment habit stops matching the vehicle is the moment it occurs. Hire cars, courtesy cars, and motors that are new to you. Households running one of each, petrol and diesel. A forecourt you know, only with its pumps laid out differently. Filling up in a hurry en route to Scarborough, with a train to catch. The first fill-up in a diesel BMW 3 Series after years of driving petrol is exactly the moment it takes place. Throw in rain, a phone call or a back seat full of kids, and your hand does what it has always done.
Newlands people: how to avoid petrol in a diesel next time
- Green for unleaded and black for diesel is usual in the UK — yet not on every forecourt. Go by the label on the pump, not the colour.
- Many vehicles state the fuel inside your filler flap or on the cap, so check there on the first fill in any motor you don't know.
- A coloured fob or a sticker on the diesel's key achieves more than any amount of intending to remember, in a house with one of each.
- "Diesel", out loud, before you pick up the nozzle — every time a new or hired car gets its first tank. It sounds silly. It works.
- Mistakes like this are easy to make while your mind is on something else, and so your phone goes away.
- Some diesels have a filler built to reject a petrol nozzle, and devices you can add are available for vehicles without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop reading the pump.
- Noticing it mid-fill? Stop there and then. A thinner mix follows from less petrol inside your tank, yet your next stage stays the same: don't fire it up.
Put petrol in a diesel around Newlands already?
Then the order of things is brief. Leave it unstarted, with the ignition switched off too. If you are still on the forecourt — Gulf or anywhere else — ask the staff to help you roll it clear of the pump. Phone 0333 366 0103 next, with three answers — your fuel, the approximate amount, and if it's run.
AdBlue, not petrol? Then say so. Corrosion and deposits, not lost lubrication, make it a separate issue — Newlands has a page all for it.
Newlands petrol in a diesel tasks: why one costs more than another
An honest single quote doesn't exist here: four situations, four separate jobs. Chiefly, the cost moves with which situation you are in. The ratio counts next, meaning how much of the tank is petrol, and then the position of the car and whether reaching it is safe for our van.
Before any quote, not after, we ask three questions: your fuel that got in, the quantity, and whether it's run. That's why. A range becomes a straight figure once the replies are in.
