How Worried Should You Be? Petrol in a Diesel Car in Lower Walton
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 fuel system — your ignition priming your pump, your starter, or driving on its own. So the fair answer to the first query everyone in Lower Walton asks, "have I ruined it?", is normally no. Petrol in Diesel is who to phone, with the motor left off, so it remains that way. Further down, you will find what petrol really does inside a diesel, how far it might have got, and how to stop it happening to you again.
Inside your engine: what petrol in a diesel really does
On its way through an engine, diesel has two jobs. Oiling comes before burning; it does both. What keeps the surfaces inside the high-pressure fuel pump and the injectors from wearing against each other is your diesel passing through them — they're designed to extremely fine clearances.
Of those two jobs, 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 strips out the protection your fuel system relies on. Petrol is also designed to resist igniting under compression — the reverse of what a diesel wants from its fuel — and that's where the knocking starts.
The shape of the problem is clear once you put those together. Contact does not do the damage — circulation does. Petrol in a tank is a fuel issue. 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 fuel injectors downstream.
How bad is petrol in a diesel? Four situations our technicians see in Lower Walton
Fuelled, and not started: no case is better. The petrol is in the tank and just that tank, and the task is a drain and a flush where your car sits. This is the one situation that can only truly happen on a forecourt, because anywhere else the vehicle has been driven to get there.
The ignition turned on, or a short start. With your system primed, your lines and filter now hold petrol that has come from that tank. That's generally still a straightforward task — a drain, a flush, and the filter seen to.
Those few miles on the road were your pump labouring on fuel weakened by petrol throughout. Tank, lines, filter, then fresh fuel put through the entire circuit: that's this work, and the way the vehicle was driven matters as much as the distance. On the school run to Stockton Heath Primary School, the distance is short. A run as far as Salford, under 15 miles away, is a very different task. So is any distance on the M56, under 3 miles from Lower Walton, where the motor has been labouring hard the whole time.
Clattering, a lumpy idle, smoke, a throttle gone soft: driven till it complained. That is your engine telling you its fuel has stopped acting like diesel. Leave it where it stops: a lay-by, a side street, the verge on Hill Cliffe Road. A vehicle stopped soon very seldom has permanent damage, since the fuel drain and the flush, which still go first, deal with it.
Stories Lower Walton drivers hear about petrol in a diesel
"Top it up the rest of the way with diesel and it'll be fine" — a myth. It won't. Topping up takes out nothing; it gives you a fuller tank of the same mix. That advice assumes a diesel fuel system tolerates petrol by percentage. It does not.
"Current diesels can handle a little petrol" — a myth, and closer to the reverse. Protection counts more on newer diesels, not less, since their fuel runs through more precise parts at higher pressure.
One myth that catches drivers off guard: if it starts and drives, it must be unharmed. A petrol motor fed diesel usually will not run, so the driver stops and the damage stops with them. While your pump grinds, a diesel fed petrol usually starts, ticks over and drives away as if nothing has happened. Running doesn't mean fine.
"A drop of two-stroke oil and drive it home" — a myth, taken from a fix from years ago, for a separate fault. It doesn't put back what petrol has thinned, and the petrol is still inside your tank afterwards.
Myth: "Drain that tank yourself and you are sorted." After your engine has run, some of that petrol is no longer inside the tank: it is in your filter and your lines, and it goes right back through your pump at the next start. On top of that, petrol drained into a can by the road is genuinely hazardous.
Petrol in a diesel: how does it occur?
Carelessness is seldom the cause, and no one means to do it. One way only, since of the nozzles: the narrower petrol one slides inside a diesel filler with almost no resistance, while the diesel one generally won't fit a petrol car. That's how the forecourt makes it simple.
Habit and the vehicle falling out of step is how it takes place. A new vehicle, a hire car or a courtesy car. Households running one of each, petrol and diesel. A forecourt you know, only with its pumps arranged differently. Racing for a train outside Warrington Bank Quay and filling up en route. A new-to-you diesel Volkswagen Tiguan, its first fuelling, and a motorist accustomed to petrol: exactly when it occurs. Add a back seat full of kids, a phone call or rain, and habit wins.
Lower Walton drivers: how to avoid petrol in a diesel next time
- Not every forecourt in the UK keeps to green for unleaded and black for diesel, though most usually do. Read the pump's label; the colour is only a hint.
- The first fill in a strange car is the time to check your filler flap — inside it, or on the cap, plenty of vehicles state which fuel they take.
- Label the key. In a house with one of each, a coloured fob or a sticker on your diesel's key does more than any amount of meaning to remember.
- Before the nozzle leaves the pump the first time you fill a hired or new motor, say "diesel" aloud. Daft, perhaps, yet it does the trick.
- Thinking about something else is when this becomes an easy mistake to make, and so tuck the phone away then keep your mind on the pump.
- Add-on devices exist for vehicles without one, and some diesels are built with a filler that will not take a petrol nozzle. Helpful — but a backstop at best, never a reason to stop checking the label.
- Less petrol means a weaker mix, so stop the moment you notice — though remembering that the next step is unchanged. It is still not to crank it.
Already put petrol in a diesel around Lower Walton?
Then the order of things is brief. Leave it unstarted, with your ignition switched off too. Ask the staff to help you roll it away from the pump if you are still at the forecourt, whether that's Texaco or anywhere else. Next, 0333 366 0103. We will ask what got in, about how much, and if it has been run.
AdBlue, not petrol? Then say so. Corrosion and deposits, not lost lubrication, make it a separate fault — Lower Walton has a page all for it.
Lower Walton petrol in a diesel jobs: why one costs more than another
Four different jobs sit behind the four scenarios above — which is why there is no fair single price. Which of them you're in is chiefly what shifts your cost. Where the car is matters too, and whether a van can safely reach it, after the ratio of petrol to what the tank takes.
That's why we ask three questions before pricing instead of after: what got in, how much, and whether it has run. With the answers, you get a straight figure rather than a range.
