Put Petrol in a Diesel Car in Fontwell?
Petrol in Diesel drains and flushes misfuelled vehicles where they are, on the forecourt, at the roadside or on a private drive, across Fontwell and the rest of West Sussex. The first thing to do is not to turn on your engine. When the engine has not turned over and the petrol is still inside your tank, a fuel drain is nearly always all it takes, and the following few minutes settle that, not how much got in. Call us before all else happens, so you will know what comes next.
Your first five minutes: petrol in a diesel
- While you drive, the pump and your injectors wear. That is why you never crank it, and why you never believe it once it has started. The thing about petrol in a diesel especially — the bit drivers get wrong — is that it drives away normally for the first mile or two. Diesel in a petrol engine normally will not run at all, which stops the person and stops the damage with them. This one lets you drive on.
- Diesel combusts, and before it ignites it protects — the high-pressure pump, its injectors. Petrol handles only the burning. So leave your ignition alone too: switching it on is usually enough to prime that system, and priming pulls petrol from that tank into just those parts.
- Do not weaken it. Diesel poured on top clears nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The octane makes no difference.
- A car that has not moved is the simplest one to sort out, and so wait where you are if you reasonably can. Parked on the verge on Fontwell Avenue? Hazards on, and leave the car there. A difficult location works for us better than a started engine.
- Keep your location prepared before you phone. A postcode beginning BN18 0 and whatever is closest to you with a sign on it is the difference between the van arriving and the van circling.
- Three details shape your whole call-out: the liquid you poured in, the ballpark volume of it, plus whether anything has been running since. The line is 0333 366 0103.
Clearing petrol from a diesel on the forecourt
Forecourts are where this work usually kicks off, and where a large chunk of it closes. Still at Shell? Then that is generally where it happens. Station forecourts are everyday for us, with the agreement of the owner.
A filling station is the only setting the mistake can be stopped before the engine has started. Our technicians can still sort it out where it is, even away from the pumps. In a car park, on a driveway or in a lay-by, the car has been fired up and driven there, and that pulled fuel through your filter then into the high-pressure pump, all the way from that tank. None of that is a disaster, though the flush then has to reach past that tank to the fuel lines and the filter, and the few seconds between reading your receipt and going for the keys are what decide that.
Wheel the vehicle out of the way if the attendants offer, and they generally will. The next driver gets through the pump, and that's worth doing. Four vehicle lengths is not worth a restart.
Petrol in the Renault Megane, and it takes diesel? Shopping in your boot, you outside Co-op Food, somewhere in Fontwell? Then call us, and leave the engine out of it — not even to leave the bay. Somebody gets to you. Tank emptied, fuel lines rinsed, clean diesel in, and home you go. Gentle throttle over a mile pulls very little, and so these are usually the simple jobs.
Easy job, this one — until someone takes it home. A diesel Nissan Qashqai parked at The Old Stables with petrol in your tank loses nothing by sitting there overnight, so park the car and phone us once it is light. Expect a query about that run there, though. Brief and cold is exactly where petrol battles to burn, and what will not burn can get past the piston rings and into the engine oil.
Rarely the trouble, the spot. On-street is the most common location our technicians work, and a tight parking space is far preferable to a vehicle that has been driven somewhere more convenient. What does help, when you call from close to Fontwell Park Racecourse, is three things: the side the filler is on, whether a technician can pull up beside without blocking the road, and if anything has run since you filled up. Then the Mercedes E-Class gets drained, the filter changed where a workable one exists, the fuel lines rinsed and fresh fuel put through the whole system — as by now the worst of that is in the lines, not your tank.
Knocking, a ragged idle, white smoke, a throttle gone soft. That is a wrongly fuelled diesel BMW 5 Series telling you what's wrong. Switch off where you have stopped, near Eastergate Village Hall or anywhere else, and do not start the vehicle to find a better location.
Somebody certain will tell you to drain the vehicle then put new diesel in. Half right, that. Try it on a diesel Audi A6 by St Mary's Church and the engine will start — which is exactly why it sounds like sense. Here is the catch: there is petrol left in the fuel filter and the feed lines, and the first thing the engine does is draw it back through the pump a second time. Draining a tank achieves nothing about fuel that already left your tank. Phone us. Your system gets cleaned, the fuel filter comes off where there is one worth removing, and that is what separates a fixed vehicle from one that simply starts.
Service around Fontwell
These same runs take us to Little Heath, Slindon, Eastergate, Slindon Common and Nyton besides Fontwell, which is a rural village.
Not on that list? That tells you nothing. The names above are just the closest few, and nearly all locations around West Sussex have a page of their own somewhere on the site. Ring us and enquire instead of assuming — county lines particularly, and wherever your phone might get wrong.
Look at our map for the ground included here. All of that is ground our engineers work: a kerbside, a forecourt, a drive, a car park. You don't move your car anywhere.
Kerbside breakdowns in Fontwell
Not everybody gets a chance to pull over somewhere suitable. If you worked it out after setting off and landed by the verge beside Arundel Road, or at a lay-by somewhere with your hazards on, that's a common call for us instead of an odd one.
Out of your car when it isn't safe to be inside, by it when it is. Every mile a diesel obliges you for on petrol pulls the blend further into the fuel system — and oblige it usually will, which is why the motor does not get restarted to limp somewhere safer. A technician driving to an inconvenient spot is no bother for us, and it's far better for the vehicle than driving on.
A couple of miles on petrol in a diesel: what next?
The local Waterlooville Bypass is the one that matters now, and it runs under 25 miles from Fontwell. A misfuelled diesel will usually get you onto it and some distance along before anything feels wrong, and the symptoms when they appear are typically a drop in power, a lumpy idle and smoke rather than a clean stop.
Take the first junction that is safe, stop there, and do not start it to reposition. On a longer drive — anything close to the under 10 miles to the nearest city — take it the contamination has been through the fuel filter, the pump and the fuel injectors, and mention it when you ring. It changes what we bring.

What comes next when our technicians arrive with you in Fontwell
- Our engineers find out what was put in, how much, and if the engine has run. The responses shape the work, which is why we ask before giving a price.
- Your tank gets emptied completely.
- Fuel lines are rinsed through and the filter cleared, leaving nothing in your system that caused any of this.
- The system gets bled, on new diesel.
- The engine is fired up and checked to confirm it runs properly on fresh diesel.
From there, you're ready to drive away. Everything is done where the car is, so it never needs to be taken to a garage, and when it has been caught quickly, long-term damage is very rare.
AdBlue in your diesel tank by mistake, around Fontwell?
If what got in was AdBlue rather than petrol, the first rule is unchanged — never start the vehicle — yet the fault isn't. The lubrication a fuel system depends on is stripped away by petrol, which weakens your diesel. Corrosion and build-up are what a diesel tank gets instead, as AdBlue is urea dissolved in water.
Frequently the more significant of the two, AdBlue — and the detail lives on its own Fontwell page. Both are ours to handle.
Fontwell costs for a petrol-in-diesel drain
One price wouldn't be honest here, since this isn't one job. These are the things that move it:
- Whether your motor has been run or driven. This is the big one.
- How much of the wrong fuel was put in, weighed against how much that tank takes.
- AdBlue or unleaded, whichever got in.
- Access: the car's position, and if working on it there is safe for a technician.
Tell us what your car is, how much got in, and if your engine has run. A straight answer comes back, not a range. Not time-critical, with your car at home and going nowhere? Then works.
Petrol in diesel questions from Fontwell drivers
Can you do a fuel drain at a petrol station in Fontwell?
A fair share of this work happens there, so yes. Tell us which one you're at when you call and we'll tell you whether our technicians can work there. With the station's consent our technicians work at Esso and the other forecourts locally all the time.
Is there a sensible amount of petrol in a diesel?
Litres aren't the yardstick. Proportion 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 mix been drawn right through, or has it not?
Petrol in my diesel, and I have driven the vehicle
Pull in somewhere sensible, turn off, then keep it off. Driving takes the problem along — out of that tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one truly valuable thing left to you isn't restarting the car.
Fuel drains and manufacturer warranties
A drain then flush carried out properly isn't a modification and doesn't void a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a disagreement with one.
Adding two-stroke oil, then driving home
What petrol has weakened is not put back by two-stroke oil, which is an old workaround for a separate problem. So no. Your tank still has petrol in it after that, and your pump still has to live with it.
Main dealers and petrol in a diesel
Wherever the vehicle is, our technicians drain and flush it there, so a drive to the main dealer does not come into it.
Still with the car?
Switched off is the way it stays.
Already driven it? Then pull over somewhere sensible, switch off, and let the vehicle remain that way. Cold, parked, going nowhere: that's the best position to be in. Motorists fear this much more than they need to.
Throughout West Sussex and in Fontwell: on-site fuel draining, at home or on the forecourt or at the kerbside.
