Northwood: Put Petrol in a Diesel Car?
Never turn on the motor. While the fuel is still inside your tank and the engine has not run, a drain is nearly always all it takes — and that gets determined in the following few minutes, not by how much went in. Petrol in Diesel drains and cleans misfuelled vehicles where they sit, throughout Northwood and the rest of Kent, on the forecourt, at the roadside or on a driveway. A single ring our way is sufficient: our team can show you what happens from here. Try that right away.
Now what? Petrol in a diesel, in turn
- Never start the vehicle. Turned on regardless? Then don't depend on it. Diesel in a petrol vehicle normally can't run, so the motorist stops and the damage stops with them. Petrol in a diesel? It starts. It ticks over. It moves off happily, for a few miles. People get that confused. It is not all right — that fuel system is wearing down every mile you do.
- Switching the ignition on commonly primes the system, and priming is what moves petrol out of your tank and into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it combusts. Petrol manages the burning and none of the protecting. Leave the ignition alone.
- Topping up removes nothing. It hands you a fuller tank of the same blend, since a diesel fuel system will not cope with petrol by percentage the way that guidance suggests — so do not tip diesel on top to water down it. Type is beside the point too: super unleaded is petrol.
- Sit tight if it's sensible to. Hazards on, motor off, leave the vehicle. Wherever you have stopped — the verge on Northwood Road, anywhere — a tricky place for us is better than a started diesel, and nothing is simpler for us to handle than a vehicle that never shifted.
- Find out where you are before calling. A postcode that starts CT12 6, and the name of whatever is closest to you. Otherwise the van circles rather than showing up.
- Dial 0333 366 0103. Expect three questions — what got in, about how many litres, and whether the car has been run. The responses settle whatever happens next.
Don't take it home. The journey in has already forced a real amount of petrol-thinned diesel through your high-pressure pump of your Ford Focus, and the trip back would about double it for no gain at all. Call us from the platform if that's handier. Our technicians do not need you standing over the car at Ramsgate while we get on, and we would far rather speak to you tonight than find out on Monday.
Straightforward, these ones, and the reason is the miles: a mile at light throttle uses very little diesel. Petrol into a diesel Peugeot 3008 somewhere around Northwood, a boot loaded with shopping, and you sat outside Lidl — phone us. Getting out of the space is never worth another start. That tank gets drained where it waits, the lines rinsed, fresh diesel in, and you head home.
Here's what a job in the car park at Northwood Club normally looks like. We get to the vehicle, ask what was put in, about how much, and whether the motor has run since — these three answers decide most of the work. Then the tainted mixture comes out of that tank, your lines get flushed, and the filter comes off where your BMW X1 has a replaceable one. Clean diesel goes in and the system is bled. Then our engineers fire it up, check it runs properly, and you drive away.
Off the forecourt, receipt read, a couple of hundred yards, left near St Mark's Church. For a diesel Volvo XC60 whose engine has turned, that's about the best version there is. Ring us, and let the vehicle stand with the ignition alone. Short helps, really — but a start is a start and a drive is a drive, and your filter has had thinned fuel through it, and so has the pump. Which is why your lines get flushed and not just your tank drained.
Drain it and put clean diesel in — that is the advice you'll get, generally from someone sure of themselves, and it's half right. Do precisely that to a diesel Hyundai Tucson by Newington Library and it would start, which is what makes the tip sound sensible. What takes place next is the problem: your engine immediately pulls the petrol left sitting in your filter and the feed lines straight back through the pump, as emptying a tank does nothing about fuel that has already left it. Phone us instead. Our engineers flush your circuit and take the filter off where the vehicle has a workable one, which is the difference between your car being put right and the vehicle only starting.
At the forecourt: removing petrol from your diesel
A good part of the job is done at a pump, since that's where it often starts. Still at Tesco? Then that is typically where it happens. Garage forecourts are everyday for us, with the consent of the site.
The forecourt is the single location the mistake gets spotted before your motor has run. We can still put it right where it stands, even away from the forecourt. In a car park, on a drive or in a lay-by, the car has been switched on 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 catastrophe, though the flush then has to go past the tank to your lines and the filter, and the few seconds between checking your receipt and reaching for the keys are what settle that.
The staff will normally happily roll the car out from the pump so the next customer can get past. It is worth doing. Shifting the car four spaces does not warrant starting the engine.
Northwood plus the villages near it
Northwood is a residential suburb, and so our team are out to it and to the areas by it on the same runs: Whitehall, Westwood, Bromstone, Newington and Haine.
Not on that list? That tells you nothing. The names above are simply the nearest few, and nearly all locations in Kent have a page of their own elsewhere on our site. Contact us and ask rather than assuming, particularly when you're on a border or somewhere a satnav misreads.
Look at the map for the patch shown here. Roadside, forecourt, driveway, car park: all of it is ground our engineers serve, and none of it asks the vehicle to come to us.
Stuck at the roadside around Northwood
Some people find no suitable spot to pull in whatsoever. If you realised after setting off and ended up along the verge beside Coxes Lane, or in a lay-by somewhere with your hazards going, that's a common call for us instead of an unusual one.
Whether you sit beside your car or move away from it turns on if being in it looks sensible. Never start up your engine to nurse it somewhere handier — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling the blend further into your fuel system. However awkward the place, it's no trouble for us to get to it, and that's much better for the vehicle than pressing on.
Driven it already? Stop, then check this
This is where the local M20 comes into it — under 25 miles away from Northwood. A drop in power, an uneven idle, smoke: those are the signs when they arrive, rather than a neat stop — and a wrongly fuelled diesel will usually get you onto it and some distance along before anything feels wrong at all.
The next safe junction is the one to take. Switch off there, then leave the restarting alone. Suppose the worst of that on a long drive. Anything close to the under 25 miles to the closest city, and the contamination has been through the fuel filter, through the pump, through the injectors. Mention it when you call. What our technicians bring changes.
All about Northwood
Northwood is a suburban area in Kent, situated near the coast and approximately 15 miles from Canterbury. Northwood sits at an elevation of around 52 metres, with a mix of semi-detached housing and other residential properties. Northwood is one of several suburban areas in the region, including nearby Whitehall, Westwood, and Bromstone. Northwood has a population of around 3746 people, making it a small but established community.
What happens when we get to you around Northwood
- Our technicians check what was put in, how much, and whether the motor has run. The responses change the work, which is why our engineers ask before quoting.
- We empty your tank of all the contaminated fuel.
- Our technicians flush the fuel lines and clear the fuel filter, so what is left in the fuel system isn't what started the trouble.
- Bleeding your system follows, once new diesel is in.
- It is fired up with clean diesel in it, and our technicians make sure that it's running properly.
After that it's ready to pull away. There's no need for a garage at any stage, because the work is all done where your car is, and when it is spotted soon, lasting damage is very rare.
AdBlue in the diesel tank by mistake, in Northwood?
AdBlue instead of petrol? Then the first instruction is unchanged — the engine stays off — whereas this issue underneath it's a separate one altogether. Petrol dilutes your diesel and removes the lubrication the fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and residue in its place.
Often the more serious of the two, AdBlue — and the detail lives on its own Northwood page. Both are ours to deal with.
What a petrol-in-diesel drain costs in Northwood
Truthfully, no single figure belongs on a page like this. The job changes. Here's what varies it:
- Started? Driven? Either answer counts more than anything else on this list.
- Wrong fuel in, against what that tank holds — that ratio.
- The kind of fluid in the tank, unleaded or AdBlue.
- Where your vehicle is, and whether our van can safely get to and work on it.
Tell us what your car is, how much went in, and whether your engine has run. A clear answer comes back, not a range. Not time-critical, with the vehicle at home and going nowhere? Then does the job.
Things we hear about petrol in diesel around Northwood
I am on a forecourt in Northwood. Can you drain it on the spot?
Yes, and it is where a large portion of this work gets done. Tell us which one you are at when you phone and we will tell you if our technicians can work there. With the site's consent our engineers attend Sainsbury's and the other forecourts nearby all the time.
How much petrol in a diesel is too much?
Whether your engine has run matters far more, though the ratio counts too, rather than the litres. An almost empty tank with five litres in it, against a full one with the same five: distinct scenarios, definitely. Either way, the work required comes down to one thing, which is whether the fuel system has had that mix drawn through it.
Already driven it with petrol in your diesel? What now?
Somewhere sensible, then stop, then turn off and leave it off. Not restarting it is the single most helpful thing available to you now. Driving does move the problem out of your tank and into your pump and injectors, yes, and it remains fixable far more frequently than drivers assume.
Fuel drains and manufacturer warranties
It isn't a modification, so a drain and flush carried out properly does not invalidate a manufacturer's warranty. What is likelier to start a disagreement is a diesel that has been run on petrol. One more good reason for the motor to stay off.
Adding two-stroke oil, then driving home
Two-stroke oil solves a different problem, and an old one at that. Nothing it does puts back what petrol diluted. No. After that? Still petrol in that tank, and a pump that has to put up with the stuff.
Do I need a main dealer for petrol in a diesel?
No. Our engineers drain and clean the vehicle wherever it is, so there's no need to take it to a main dealer.
Standing next to it?
Don't switch your engine on again.
Already driven it? Then stop somewhere safe, turn off, and let the vehicle stay that way. Cold and stationary, a vehicle is in the best place available — and people fear this a lot more than the recovery rate warrants.
