Bockhanger: Put Petrol in a Diesel Car?
With the tank still holding the petrol and the engine not yet run, nearly every job takes only a drain, so leave the motor off. That outcome is settled in the minutes straight after the fill-up, and not by the amount that got in. Throughout Bockhanger and the rest of Kent, Petrol in Diesel drains the vehicle and flushes it where it sits, whether at a roadside, on a private drive or at a forecourt. A single ring to us is enough: we can show you what comes from here. Make it right away.
What to try now about petrol in a diesel
- Whenever you drive, the pump and the fuel injectors wear. That's why you don't fire it up, and why you do not depend on it once it has started. The catch about petrol in a diesel especially — the point most people get wrong — is that it pulls away happily for the first mile or two. Diesel in a petrol motor normally can't run at all, which stops the person and stops the damage with them. This one lets you keep going.
- Two things, diesel: it combusts, and on the way through it keeps your high-pressure pump and injectors oiled. Petrol only manages the one. That is why your ignition is left off also — flick it on and you often prime your system, and that's petrol leaving your tank for exactly those parts.
- Topping up takes out nothing. It gives you a bigger tank of the same mix, since a diesel fuel system does not tolerate petrol by percentage the way that advice implies — so do not tip diesel on top to thin it. Octane is beside the point too: super unleaded is petrol.
- A car that hasn't moved is the easiest one to sort out, so wait where you are if you safely can. Parked on the verge on Belmont Road? Hazards on, and keep it there. A tricky spot works for us better than a started motor.
- Check where you are before ringing. A postcode that starts TN24 9, and the name of whatever is closest to you. Otherwise the van circles instead of turning up.
- Three facts determine the full visit: the liquid you put in, the ballpark volume involved, and whether anything has been turning since. The line is 0333 366 0103.
The drive in is what drew diluted diesel through the pump. Sitting still has pulled nothing. Petrol in a diesel Renault Megane, parked at Ashford International all day, rests harmless in that tank while it waits. Ring us first — before the keys go in.
Any start primes that fuel system and pulls more of the mix out of that tank and towards your pump — which is why a motor moved twice into a better spot has quietly become a worse job than one left exactly where it stopped. So if our technicians can't work next to your diesel Audi A4, our technicians shift it without starting it. None of that is fuss about a handful of seconds of running. Car parks like the one at M&S Foodhall our technicians work in all the time, and your fuel is seldom the awkward part: that bay is. Vehicles either side, a trolley shelter behind, sometimes a height limit at the entrance determining whether our van gets to you at all. Tell us how penned in you are, and which way the car points.
Here is what a job in the car park by Bybrook Tavern normally looks like. Our technicians get to your car, ask what got in, roughly how much, and whether your engine has run since — these three replies decide much of the work. Then the contaminated blend comes out of the tank, the lines get flushed, and the filter comes off where your BMW 5 Series has a replaceable one. New diesel goes in and the fuel system is primed. Then our engineers start it, check it runs properly, and you drive away.
Most of these occur somewhere unfamiliar, and the cause is mechanical instead of careless — almost no resistance meets a smaller petrol nozzle entering a modern diesel filler neck. Two days into a diesel Vauxhall Insignia, a fill-up near The Church of Jesus Christ of Latter-day Saints that you did not think about? Call us from where you are. Courtesy and hire cars go further before anyone spots it, and the further they go, the more petrol winds up at your injectors.
A person certain will tell you to drain the car and put clean diesel in. Half right, that. Try it on a diesel Citroen C4 Picasso by Kennington United Reformed Methodist Church and the engine will start — which is precisely why it sounds like sense. Here is the catch: there is petrol left in the filter and the feed lines, and the first thing the motor does is pull it back through the pump again. Draining a tank achieves nothing about fuel that already left that tank. Call us. Your circuit gets purged, the fuel filter comes off where there's one worth removing, and that is what separates a fixed car from one that only starts.
Pump-side drains for petrol in a diesel
Forecourts are where the work usually starts, and where a fair share of that finishes. We work on petrol station forecourts routinely, with the station's consent, so if you're still at Willesborough Kennington Garages that's usually where this drain happens.
Nowhere except the forecourt can it be caught with your engine still untouched. Fuel sucked out of the tank and through the filter, all the way to the high-pressure pump, is what happens when the engine is started and your car is moved to where it is now: the car park, the driveway or the lay-by, everywhere other than the forecourt. So the flush includes your filter and your lines as well as that tank. That is still not a disaster, and our engineers sort it out where your car sits. What determines it is whether the ignition was reached for in the seconds after the till receipt was checked.
Move the car out of the way if the attendants volunteer, and they usually will. The next motorist gets through the petrol pump, and that's worth doing. Four car lengths is not worth the risk.
Areas our team serve in Bockhanger
Bockhanger is a residential suburb, and our technicians are out to it and to the places near it on the usual journeys: Bybrook, Kennington Lees, Kennington, Goat Lees and Barrow Hill.
Not on that list? That says nothing. The names above are just the nearest few, and most towns around Kent have a page of their own somewhere on this site. Close to a boundary, or somewhere the satnav misreads? Contact us and check instead of guessing.
This map is the area this page includes. We work at the roadside, at forecourts, on driveways and at car parks over all of it, and the vehicle does not need to travel to us.
Stranded at the kerbside anywhere around Bockhanger?
The chance to stop anywhere sensible does not come to everyone. Set off, then realised? Landed by the verge on Grasmere Road, or sat in some lay-by with the hazards going? That's a normal call here. Not a rare one.
Wait with the vehicle if it's sensible to sit in it, and clear of it when it's not. It will often oblige. A diesel running on petrol limps along quite willingly, and that's the trouble: fire it up to get to somewhere better and the mix goes further into the fuel system with every mile travelled. A technician driving to an awkward place is no trouble for us, and it is much better for the car than pressing on.
Petrol in a diesel, but the vehicle has gone
This is where your M20 comes into it — under a mile away from Bockhanger. Some way along, and onto it in the first place: a misfuelled diesel will usually do both before anything feels wrong. What you get then is seldom a neat stop. Power ebbs away, your idle goes lumpy, and there may be some smoke.
Take the next junction that is safe, pull up there, and never restart it to reposition. On a longer drive — anything near the under 15 miles to the nearest city — assume the petrol has been through the fuel filter, your pump and the injectors, and say so when you ring. It affects what our technicians bring.

What we do when we arrive with you in Bockhanger
- Our engineers ask first, price after. What went in? How much? Has the motor run? Those responses shape what the work really is.
- The polluted mixture comes out of that tank.
- What is remaining in the fuel system should not be what created the trouble, and so the lines get purged and your filter cleared.
- Your system gets primed, on clean diesel.
- It is started with clean diesel in it, and we check that it's running correctly.
Your car is then ready for you to pull away. There is no need to go to a garage at any stage, since the work is all done where the car is, and when it is spotted early, lasting damage is very unusual.
AdBlue in a diesel tank in Bockhanger is a separate problem
If what went in was AdBlue instead of petrol, the first instruction is unchanged — never fire it up — but the problem is not. Thinned diesel, and no lubrication left for the fuel system that depends on it. That's petrol. AdBlue? Urea dissolved in water. Put that in with your diesel and you get corrosion instead, plus residue.
Often the more serious of the two, AdBlue — and the details sits on its own Bockhanger page. Both are ours to deal with.
What a petrol-in-diesel drain costs around Bockhanger
One price wouldn't be fair here, as this is not one job. These are the things that move it:
- Has it been started or driven? Nothing else counts for as much.
- Wrong fuel in, against what the tank holds — that proportion.
- Which was put in: unleaded or AdBlue.
- Where the car is, and if a technician can sensibly reach and work on it.
Tell us your car, the quantity and whether it has run, and you will get a clear answer instead of a range. Not time-critical, with your car at home and going nowhere? Then is fine.
Things our engineers get about petrol in diesel in Bockhanger
At a petrol station around Bockhanger, can you do a fuel drain there?
Yes — forecourts are where a large share of this gets done. Routinely, provided the site agrees: Sainsbury's, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that place is something our engineers answer there and then.
Is there a sensible quantity of petrol in a diesel?
Proportion decides it instead of litres — and more than either, whether your motor has run. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same query in the end: has that mixture been pulled right through, or has it not?
I put petrol in my diesel and drove it. What now?
Stop sensibly. Off. Nothing after that. Driving moves the problem along — out of the tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one genuinely helpful thing left to you isn't restarting it.
Will a fuel drain void my warranty?
A drain and flush carried out properly isn't an alteration and doesn't cancel a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Can I just add two-stroke oil and drive home?
Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol weakened. No. That tank still has petrol in it after that, and your pump still has to put up with it.
Do I need a main dealer for petrol in a diesel?
Wherever your car is, we drain and clean it there, so a drive to the main dealer does not come into it.
Standing next to it?
Don't turn it on again.
If you have already driven it, stop somewhere sensible, turn it off then keep it off. Cold and stationary, a motor is in the best place available — and people fear this a lot more than the recovery rate warrants.
