Pulborough: Put Petrol in a Diesel Car?
With the tank still carrying the fuel and the engine not yet run, almost every job needs only a drain, so keep your engine off. That outcome is determined in the minutes straight after filling up, rather than by the amount that was put in. All over Pulborough and the remainder of West Sussex, Petrol in Diesel drains the vehicle and cleans it where it sits, whether at a roadside, on a private drive or at a forecourt. A single call to us is enough: our technicians will explain what follows from here. Make it right away.
What to do now about petrol in a diesel
- Don't start the car. Started regardless? Then never believe it. Diesel in a petrol car normally won't run, and so the motorist stops and the harm halts with them. Petrol in a diesel? It starts. It ticks over. It moves off fine, for a few miles. Motorists get that confused. It isn't all right — that fuel system is wearing every mile you drive.
- Diesel burns, and before it ignites it greases — your high-pressure fuel pump, the injectors. Petrol handles only the burning. So leave your ignition off also: switching it on is frequently enough to prime the system, and priming draws petrol from that tank into just those parts.
- Topping up gets rid of nothing. It gives you a bigger tank of the same mixture, because a diesel fuel system doesn't handle petrol by percentage as that guidance assumes — so do not put diesel on top to water down it. Type is immaterial too: super unleaded is petrol.
- A vehicle that hasn't moved is the simplest one to handle, so wait where you are if you sensibly can. Stopped on the verge on Barnhouse Close? Hazards on, and keep it there. An awkward location works for us better than a started motor.
- A van arriving rather than circling turns on two things: a postcode that starts RH20 2, and whatever is closest to you with a label on it. Get both ready before you dial.
- Three replies determine the whole job: the stuff you poured in, the ballpark measure involved, and if anything has been running since. The number is 0333 366 0103.
How far you drove is what we query, not how long your vehicle has been stood — and this is why. Diesel performs two tasks on its way through a motor: it combusts, and before burning it protects its injection pump and the injectors. Petrol does the first only. So a quick fill-up on the drive in, it dawning on you at about eleven, and a diesel Volkswagen Golf left outside the nearest station since quarter past eight means those few miles were driven with the pump labouring on a fuel drained of a lot of its protection. Phone us and leave it exactly where it is.
The call we like goes like this: diesel BMW 3 Series, some litres of unleaded, done a couple of miles, now turned off at Tesco. What we are really asking is how much fuel your pump has pulled — not how long ago it was.
Move it out of the gateway and deal with it later — that is what a passer-by will say, and it is wrong. Sitting on the zig-zags by St Mary's Church of England Primary School, a misfilled diesel Ford Focus is a nuisance and nothing worse. Fired up three more times for politeness, it is no longer a tank problem but a fuel system one, because priming occurs with every start and more petrol goes past the fuel filter on to your pump. Let everyone complain. Give us a call.
Why so direct about leaving the keys alone? Since your pump is before the fuel injectors, and a worn one sends whatever it gives off downstream with your fuel. Ring us. Leave the Peugeot 208 by Pulborough Village Hall.
Drain it and put clean diesel in — that's the advice you will get, normally from somebody sure of themselves, and it's half true. Do exactly that to a diesel Mercedes GLC close to Moat and it would start, which is what makes the suggestion sound plausible. What happens next is the issue: your engine at once sucks the petrol still waiting in your filter and the feed lines straight back through your pump, as emptying a tank does nothing about fuel that has already left it. Ring us instead. Our engineers flush your circuit and take the fuel filter off where your vehicle has a workable one, which is the difference between your car being fixed and the vehicle simply starting.
Pump-side drains for petrol in a diesel
A large share of the work ends up done at a forecourt, since that is where it often kicks off. Our technicians work on petrol station forecourts routinely, with the site's permission, so if you're still at Elite Garages that's typically where the drain happens.
Before your engine has fired — a garage is the only spot the mistake is stopped. The few seconds between checking the receipt and reaching for the key settle how much needs rinsing. Anywhere other than a forecourt — a car park, a drive, a lay-by — the car was started and moved to get there, so fuel was drawn from your tank, through your filter and into the high-pressure fuel pump. That means your lines and the fuel filter require cleaning as well as that tank. It's not a calamity, and our engineers can still deal with it where the car stands.
The staff will normally happily wheel the vehicle away from the petrol pump so the next customer can get through. That is worth doing. Firing the car just to roll four car lengths is not.
Areas our team reach in Pulborough
As a village, Pulborough has a regular visit, whilst the places round about go along on the same round: Marehill and Broomershill, Codmore Hill and Lickfold, Wiggonholt.
We still come. Those places above are just the immediate neighbours, and a page exists for most places around West Sussex, so an absence from the list isn't an absence from our coverage. Call us and enquire rather than guessing, particularly if you're on a border or anywhere a satnav can't find.
This map marks the ground the page includes. Roadside, forecourt, private drive, car park: all of it is ground we work on, and none of that asks your vehicle to come to us.
Stranded at the kerbside near Pulborough
Not everyone has a safe spot to stop. Set off, then realised? Ended up along the verge on Carpenters Meadow, or parked in some lay-by with the hazards on? That's a routine call here. Not an odd one.
Whether you stay with the car or stand away from it rests on if sitting nearby looks sensible. Don't fire up the motor to nurse the vehicle somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling the mix further into the fuel system. However tricky the spot, it's no bother for us to get to it, and that is far better for your car than driving on.
A couple of miles on petrol in a diesel: now what?
The local M23 is the one which counts here, and lies under 25 miles from Pulborough. A misfuelled diesel will often get you onto it and some way along before anything seems wrong, while the signs when they arrive are normally a loss of power, a lumpy idle and some smoke rather than a clean stop.
Come off at the next sensible exit, switch off, and never restart it to move it. On a longer run — anything near the under 15 miles to the closest city — assume the mixture has been through the filter, the pump and the fuel injectors, and say so when you phone. It changes what our technicians bring.
A little about Pulborough
Pulborough is a village situated on the banks of the River Arun in West Sussex, with a low elevation of around 17 metres. Pulborough is located near several smaller settlements, including Marehill, Broomershill, and Codmore Hill, and is approximately 14.7 miles from the city of Chichester. Pulborough has a population of around 1917 people, predominantly living in semi-detached housing. Pulborough is also within commuting distance of London, being around 41.3 miles from the capital.
What follows when our engineers arrive with you in Pulborough
- The answers shape the work, which is why we ask before pricing: what went in, how much of that, and whether the engine has run.
- Your tank gets drained completely.
- Fuel lines are cleaned through and the fuel filter cleared, leaving nothing in the system that started any of this.
- The system gets bled, on clean diesel.
- Our technicians turn it on and make sure it runs smoothly on new diesel.
From that point, you're ready to set off. Our technicians do everything wherever the car has come to a stop, which means it never needs to go to a workshop, and when it has been noticed quickly, it is very uncommon for there to be long-term damage.
A different job: AdBlue in a diesel tank in Pulborough
If what got in was AdBlue rather than petrol, the opening rule is the same — never fire it up — yet the problem isn't. Petrol does two things to diesel: thins it, and takes away the lubrication the fuel system relies on. Urea dissolved in water, AdBlue, and in a diesel tank that causes rust and residue.
AdBlue removal around Pulborough has a page of its own with the detail on it, including why it's often the more serious of the two. Our engineers deal with both.
Budgeting for a petrol-in-diesel fuel drain in Pulborough
What moves the price is listed below, because this job is not one job and we cannot honestly put a single price on this page.
- Has it been started or driven? Nothing else matters for as much.
- How much of the wrong fuel was put in, set against how much the tank can hold.
- AdBlue or unleaded, whichever got in.
- Whether our van can safely reach the vehicle and work on it, which depends on where the car is.
The vehicle, the amount, whether it has run — give us those and the answer comes back straight rather than as a range. Not urgent, with the car at home and going nowhere? Then does this job.
Petrol in diesel: common questions in Pulborough
Fuel drains on a Pulborough petrol station forecourt
A big portion of this work gets done there, so yes. Permission from the site is the condition. Given that, a forecourt like JET is somewhere we're regularly, along with the rest of them locally — so name yours on the phone and you will hear whether working there's possible.
How much petrol in a diesel is too much?
Litres are not the yardstick. Ratio is, and much more than either, it matters whether anything has been run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same query in the end: has that mixture been drawn right through, or has it not?
Already driven it with petrol in the diesel? What then?
Stop sensibly. Off. Nothing after that. Driving is what takes the problem from the tank into the pump and injectors — but it's recoverable far more frequently than people assume, and the single most useful thing you can do now is not restart the car.
Fuel drains and manufacturer warranties
It isn't a change, and so a drain and flush carried out correctly does not cancel a manufacturer's warranty. Another good reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a disagreement with one.
Two-stroke oil in your tank, and then home?
Two-stroke oil solves a separate fault, and an old one at that. Nothing it does puts back what petrol weakened. No. Petrol stays in that tank after that, whatever else goes in, and the pump gets no reprieve from it.
Do I need a main dealer for petrol in a diesel?
Wherever your car is, our engineers drain and clean it there, so a visit to the main dealer doesn't come into it.
Is your car still with you?
Keep the car shut off.
Already driven it? Then pull over somewhere sensible, switch off, then let the vehicle remain that way. Cold and stationary, a car is in the best position available — and motorists fear this a lot more than the recovery rate warrants.
