Put Petrol in a Diesel Car in Blue Town? Don't Start It
Never fire up the engine. If the fuel is still sitting in your tank and your engine has not yet run, a tank drain is almost always all it requires — and that is settled in the coming few minutes, not by how much went in. Petrol in Diesel drains and flushes misfuelled cars where they sit, across Blue Town and the rest of Kent, on the forecourt, at the roadside or on a driveway. Phone before everything else starts, so you'll learn what happens after that.
What now? Petrol in a diesel, in turn
- Whenever you drive, the pump and the injectors wear down. This is why you do not start the vehicle, and why you do not trust it once it has started. The thing about petrol in a diesel especially — the bit motorists get wrong — is that it pulls away happily for the first mile or two. Diesel in a petrol engine generally won't run at all, which stops the motorist and stops the harm with them. This one lets you carry on.
- Diesel ignites, and before it burns it protects — that high-pressure fuel pump, those injectors. Petrol manages only the burning. So leave the car's ignition alone too: turning it on is frequently enough to prime your system, and priming pulls petrol from the tank into exactly those components.
- Do not dilute it. Diesel poured on top clears nothing, and so all you get is more of what was already there, since percentage isn't how a diesel fuel system handles petrol. Super unleaded? Still petrol. The grade makes no difference.
- Stay still if it's sensible to. Hazards on, engine off, leave the car. Wherever you have stopped — the verge on Sheppey Street, anywhere — an odd spot for us is better than a started engine, and nothing is simpler for us to deal with than a motor that never shifted.
- Find out where you are before ringing. A postcode that starts ME12 1, and the name of whatever is nearest to you. Otherwise the technician circles instead of turning up.
- Three facts determine the whole visit: the liquid you poured in, the rough amount involved, and if anything has been going since. The line is 0333 366 0103.
How many miles you travelled is what we ask about, not how long the car has been parked — and this is why. Diesel has two roles on its way through an engine: it combusts, and before burning it lubricates that high-pressure fuel pump and its injectors. Petrol handles the first only. So a rushed top-up on the trip in, the realisation coming at about eleven, and a diesel Volkswagen Passat standing at Sheerness-On-Sea since quarter past eight shows those few miles were travelled with your pump labouring on a liquid robbed of most of its protection. Ring us and keep the vehicle just where it is.
Tell us this much and our technicians can work with it: a diesel Renault Clio, some litres of unleaded in it, two miles or so, turned off outside Tesco now. Time passed isn't the thing our engineers need. Fuel sucked by your pump is.
Twenty to nine outside St Edward's Catholic Primary School, already late, and your receipt in your hand reads unleaded. Hazards on, engine off, phone us. Three miles in the BMW 3 Series feels like nothing, but a diesel pump meters fuel to demand — while a hurried morning dash demands plenty.
A diesel Nissan Qashqai parked in the parking area by Red Lion holding a tank full of petrol in it is a straightforward job, right up until somebody takes it home. Park it overnight and phone next morning. Nothing worsens whilst it waits. What we'll ask about is whether that drive there was short and cold, as that's where petrol is slowest to burn properly — and anything that does not burn can work past the piston rings then into the sump.
Diesel has to be viscous enough to seal the tightly fitted parts it flows through, and petrol weakens it. That's the entire process, and it accounts for the ordinary Vincent Gardens call: a diesel Dacia Duster that drove out there without complaint and came back down on power, rough at idle, possibly smoking a little. A diesel injection system works hydraulically as well as chemically — it requires the fuel to hold pressure, not merely to burn — so when the fuel weakens, pressure that should build then stay built starts leaking past gaps instead, and your engine gets a weaker, later, less even delivery than it was built about. None of that is the motor failing, which is the part worth hearing: it's the fuel no longer acting like diesel, and it stops when your fuel is sorted.
Draining petrol from your diesel on the forecourt
A good share of the work ends up completed at a pump, since that is where it often starts. The drain usually happens on the spot. Still on the forecourt at Tesco? Given the station's consent, that is somewhere our engineers work, and routinely.
At a garage, the mistake gets spotted with the motor never run, and nowhere else does that. We can still put it right where it stands, even away from the pumps. In a car park, on a private drive or in a lay-by, the car has been switched on and moved there, and that pulled fuel through your filter and into the high-pressure pump, right from your tank. None of that is a calamity, though the flush then has to go past the tank to the lines and your filter, and the few seconds between seeing your receipt and reaching for the keys are what determine that.
Away from the pump, the next motorist can get past — so yes, let the staff help you move it. Very much worth doing. Four car lengths is not worth the risk.
Places our team reach in Blue Town
Sheerness, Mile Town, West Minster, Marine Town, Halfway Houses — all of those on our trips that bring us over to Blue Town as well, a residential suburb.
Our technicians still come. Those names above are just the immediate neighbours, and a page exists for the majority of locations across Kent, and so an absence from the list is not an absence from our coverage. Near a boundary, or somewhere your phone struggles with? Call us and check rather than guessing.
That map shows the area this page spans. The lot is territory our technicians work: a kerbside, a forecourt, a drive, a car park. You don't drive the vehicle anywhere.
Kerbside breakdowns in Blue Town
Some drivers find no sensible spot to stop whatsoever. If you noticed after setting off and finished up on the verge beside East Lane, or in a lay-by somewhere with the hazards flashing, that is a routine call for us instead of an unusual one.
Whether you remain beside the car or keep away from it turns on whether sitting nearby seems wise. Don't start it up to get to a nicer location. It'll go — a diesel on petrol normally obliges — and each mile of obliging draws the mix deeper into the system. Carrying on does the car far more harm than our van coming out to an awkward place, and that's no trouble for us.
Run it already? Pull over, and see this
Your M2 is the road that counts here, and sits under 10 miles from Blue Town. Lost power, an uneven idle, some smoke: those are the signs when they arrive, instead of a tidy stop — and a misfuelled diesel will often take you onto it and some distance along before anything seems wrong at all.
Take the first exit that is safe, pull up there, and never restart the vehicle to reposition. Long trip? Anything near the under 10 miles to the closest city and you should presume the lot — filter, pump, injectors, all of it reached by the contamination. Say that on the phone, as it affects what goes in our van.
A bit about Blue Town
Blue Town is a small suburban area located on the coast of Kent, with a low elevation of around 2 metres above sea level. Blue Town sits near the mouth of the Medway estuary, close to the nearby towns of Sheerness and Southend-on-Sea. Blue Town is characterized by its predominantly terraced housing stock, reflecting its development as a residential area. Blue Town is situated within commuting distance of London, approximately 38 miles to the west.
Once our engineers get to you around Blue Town: what follows
- The replies change the work, which is why our technicians ask before giving a price: what went in, how much of that, and whether your engine has run.
- We drain that tank of the tainted mixture.
- Lines cleaned, filter cleaned. Whatever is left later on is not the thing that caused the trouble.
- Priming follows, once fresh diesel is in.
- It's started with clean diesel in it, and our engineers make sure that it is running smoothly.
The car is then ready for you to pull away. Everything is done where your car is, so it never needs to be taken to a garage, and when it has been noticed early, lasting damage is very uncommon.
A different job: AdBlue in a diesel tank in Blue Town
The fault is not the same, though the first instruction is — never fire it up — if what got in was AdBlue rather than petrol. Petrol weakens your diesel and removes the lubrication the fuel system depends on. AdBlue? Urea dissolved in water. Tip that in with the diesel and you get rust instead, plus deposits.
Often the more significant of the two, AdBlue — and the full story lives on its own Blue Town page. Both are ours to handle.
Blue Town prices for a petrol-in-diesel fuel drain
What changes the figure is listed below, since the job isn't one job and our technicians cannot honestly put a single price on this page.
- Has it been started or driven? Nothing else counts for as much.
- How much of the wrong fuel got in, weighed against how much your tank holds.
- Whether it's unleaded or AdBlue.
- Whether a technician can safely get to the vehicle and work on it, which hinges on where the car is.
The car, the amount, whether it has run — give us those and the answer comes back straight instead of as a range. For the vehicle at home that's going nowhere and isn't urgent, is fine too.
Blue Town motorists ask us these about petrol in diesel
Fuel drains on a Blue Town petrol station forecourt
Much of what our technicians do happens nowhere else. So yes. Consent from the site is the condition. Given that, a forecourt like Shell is somewhere we're frequently, along with the rest of them locally — so name yours on the call and you will hear if working there's possible.
How much petrol is too much for a diesel?
It depends on the proportion instead of the litres, and a lot more on whether the motor has run. Five litres in a nearly empty tank is a different matter from five in a full one — but either way, the thing that determines how much work is needed is if that blend has been sucked through your fuel system.
Petrol in my diesel, and I have driven the car
Somewhere safe, then stop, then switch off and keep it off. Driving takes the problem along — out of your tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you is not restarting the vehicle.
Is a fuel drain going to void my warranty?
A drain and flush carried out properly isn't a change and doesn't invalidate a manufacturer's warranty. Running a diesel on petrol is the thing likelier to cause an argument with one, which is another good reason to leave the car turned off.
Two-stroke oil in that tank, and then home?
No. It belongs to a different issue from a different era, and petrol has thinned something no oil of that kind replaces. The pump still has to live with it, since your tank still has petrol in it afterwards.
A main dealer for petrol in a diesel — essential?
Not at all. Our technicians drain and clean the vehicle wherever it is, so there's no need to bring it to a franchised dealer.
You, and the car, still together?
Don't turn it on again.
Driven it already? Then somewhere sensible, stop, switch off, and no restarting it later. This is recoverable from much more commonly than motorists fear, and a parked, cold vehicle is the best position to be in.
At the kerbside, on the forecourt or at home — on-site fuel draining around Blue Town and throughout Kent.
