Don't Start It Petrol in Diesel drains and cleans wrongly fuelled cars where they stand, on the forecourt, by the roadside or on a driveway, all over Hurst Green and the rest of East Sussex. The first thing to do is not to start the engine. While your engine has not been started and the petrol is still sitting in that tank, a fuel drain is nearly always all it takes, and the following few minutes settle that, not how much was put in. Just one ring our way is sufficient: our technicians will explain what happens after this. Do it right away. ## Petrol in a diesel: what to try first - While you drive, the pump and your injectors suffer. That's why you never fire it up, and why you never believe it once it has started. The thing about petrol in a diesel especially — the bit people get wrong — is that it drives away fine for the first mile or two. Diesel in a petrol motor typically cannot run at all, which stops the driver and stops the damage with them. This one lets you drive on. - Leave your ignition off too. Diesel performs two tasks: it combusts, and before it ignites it protects that high-pressure pump and its injectors. Petrol manages the first but not the second. Flicking your ignition on is frequently enough to prime that system, which moves that petrol out of your tank and into just those parts. - Don't weaken it. Diesel put on top gets rid of nothing, so all you get is more of what was already there, since percentage isn't how a diesel fuel system tolerates petrol. Super unleaded? Just petrol. The grade makes no difference. - We would rather travel to a difficult location than have it started — so if you sensibly can, stay still. Nothing is simpler to sort than a car that has not shifted. On the verge on London Road, that means hazards on then leave the vehicle. - Before you phone, get your position. Anything next to you with a label on it, plus a postcode that starts TN19 7 — that's what settles whether our van turns up or circles. - Three facts decide the whole visit: the fuel you tipped in, the ballpark measure of it, plus if it has been running since. The number is 0333 366 0103. Petrol in a diesel Volkswagen Passat, left at Etchingham since this morning? The afternoon has lost you nothing — fuel sitting in a tank is dormant. It was the journey in that drew diluted diesel through the pump. Phone us before you move the car. ## Can petrol be drained from your diesel at the forecourt? Pumps are where this job often starts, and where a big chunk of it closes. Still at Shell? Then that is generally where it gets done. Garage forecourts are normal for us, with the consent of the station. Before your motor has run — the forecourt is the one spot it is spotted. Fuel pulled out of your tank and through your filter, all the way to the high-pressure pump, is what happens when your engine is fired up and your car is moved to where it is now: the car park, the private drive or the lay-by, everywhere other than the forecourt. So the flush covers your filter and your lines along with your tank. That is still not a calamity, and our engineers deal with it where your car is. What decides it is whether the ignition was reached for in the seconds after the receipt was checked. The staff will usually happily roll the car clear of the petrol pump so the next driver can get by. It is worth doing. Moving it four spaces doesn't merit cranking the motor. ## Service around Hurst Green Coopers Corner, Burgh Hill, Silver Hill, Swiftsden, Etchingham — each of those on the runs that bring us out to Hurst Green itself, a rural village. There are pages for most locations across East Sussex, and the ones named above are just the closest neighbours — so yours being absent from the list means nothing whatsoever about if our engineers come. Contact us and enquire rather than presuming, above all if you're on a border or somewhere the satnav struggles with. This map outlines the area the page includes. The lot is ground we serve: a roadside, a forecourt, a private drive, a car park. You do not move the car anywhere. You'll be told to shift it clear of that gateway and sort it out later. Don't. On the zig-zags by Hurst Green Church of England Primary School and Nursery, a misfuelled Mercedes C-Class running on diesel is in the way, and that is all it is. Crank it three more times being courteous and you have turned a tank into a fuel system: every start primes the fuel lines, every prime drags more petrol past your filter on to the pump. Let them moan. Call us. ## Kerbside stops in Hurst Green Not everybody has a decent spot to pull in. Set off, then twigged? Ended up along the verge of McMichaels Way, or stuck in some lay-by with the hazard lights flashing? That is a common call here. Not a rare one. Whether you wait by your car or move away from it rests on if being in it seems safe. It will usually oblige. A diesel running on petrol limps along perfectly willingly, and that's the problem: start it up to get to somewhere better and the blend goes further into the fuel system with every mile driven. Our van coming to a tricky location is no bother for us, and it is much better for your car than carrying on. ## Petrol in a diesel, and the car has moved The M20 is the one which matters here, and runs under 25 miles from Hurst Green. A misfilled diesel will frequently take you onto it and some distance along before anything seems wrong, while the symptoms when they come are usually a loss of power, an uneven idle and some smoke instead of a clean stop. The next safe exit is the one to take. Switch off there, then leave the restarting alone. It alters what we bring, and so say so when you ring: on a longer run — anything near the under 50 miles to the nearest city — assume the petrol has been through the fuel filter, your pump and the fuel injectors. Here is the whole mechanism. Diesel needs enough body to seal the fine gaps it goes through, and petrol takes that away. That's it. Which accounts for the normal Hurst Green Park call — a diesel BMW 5 Series, out there without complaint and back down on power, rough at idle, possibly a bit of smoke. Injection systems work hydraulically as well as chemically, and so the fuel has to hold pressure and not just burn; weakened, it escapes past those gaps and not building, and delivery comes poorer, later, less even than the engine was designed round. Not a failing engine, though. Fuel that has stopped behaving like diesel. Put that right and it stops. ## Hurst Green itself Hurst Green is a rural village in East Sussex, situated inland at an elevation of around 75 metres. Hurst Green lies near several small settlements, including Coopers Corner, Burgh Hill, and Silver Hill, and is approximately 29.9 miles from Brighton and Hove. Hurst Green has a population of around 921 people and is characterised by predominantly detached housing. Hurst Green is also within commuting distance of London, being around 42.6 miles from the capital. ## Once our engineers reach you around Hurst Green: what happens - Three things get checked before any quote — your fuel that was put in, the amount, and whether anything has been run since. Each answer changes the work. - The tainted mixture comes out of the tank. - Lines cleaned, filter cleared. Whatever is left later is not the thing that caused the trouble. - Priming follows, once new diesel is in. - The engine is fired up and tested to confirm it runs correctly on fresh diesel. From there, you're ready to drive away. We do all of it wherever your car has stopped, which means it never has to be taken to a workshop, and if it has been caught soon, it's very unusual for there to be lasting damage. Our engineers purge the lines rather than only emptying that tank, and the reason is that diluted fuel has already reached the filter and your pump: it was a start and a drive, however short. The hop genuinely helps — pulled off the forecourt, receipt read, a diesel Kia Sportage parked up by Hurst Green Village Hall a few hundred yards later is about as well as this goes once the engine has turned. Ring us and leave it off. ## A distinct matter: AdBlue in a diesel tank around Hurst Green Do not start it: that opening step stands whether what was put in was AdBlue or petrol. What changes is this fault itself. The lubrication a fuel system relies on gets taken away by petrol, which weakens the diesel. Urea in water, AdBlue, and in a diesel tank that leads to rust and deposits. Frequently the more serious of the two, AdBlue — and the detail sits on its own Hurst Green page. Both are ours to handle. Hire car or company car? Call them before you call us — some contracts want the hire firm to authorise the work, and sorting that out first is a great deal faster than sorting it after that. Then ring us about the Vauxhall Insignia close to Holy Trinity, and do not worry that you cannot say how full that tank was. Almost no one can, in a vehicle they collected two days ago, and we work it out on site. The reason our technicians ask is that petrol in a diesel does its damage as a proportion: the same few litres in a nearly empty tank is a far stronger mixture than in a full one. Petrol is rated on how well it withstands igniting under pressure, which is the opposite of what a diesel needs — so the stronger the blend, the more it rattles, smokes and goes flat. ## What a petrol-in-diesel fuel drain will cost in Hurst Green Frankly, no single price fits on a page like this. The job changes. Here's what varies it: - Has it been run or driven? Nothing else counts for as much. - The tank's capacity, set against how much of the wrong fuel went into it. - The kind of liquid in the tank, unleaded or AdBlue. - Where the vehicle is, and whether our van can safely reach and work on it. Tell us the vehicle, the amount and if it has run, and you will get a firm answer rather than a range. If it is not time-critical — the car is at home and going nowhere — is fine too. ## Petrol in diesel: common queries around Hurst Green ## Fuel drains on a Hurst Green petrol station forecourt Yes, and it is where a big part of this work happens. Permission from the site is the condition. Given that, a forecourt like BP is somewhere we're often enough, along with the rest of them locally — so name yours on the call and you'll hear whether working there is possible. ## Is there a safe amount of petrol in a diesel? Litres are not the yardstick. Proportion is, and far more than either, it matters whether anything has been run. An almost empty tank with five litres in it, against a full one with the same five: different situations, of course. Either way, the work needed comes down to one thing, which is whether your fuel system has had that mix pulled through it. ## I drove the car after putting petrol in my diesel. What next? Switch off somewhere sensible, and keep it that way after you stop. It is salvageable much more commonly than people assume, even though driving is what moves the problem from that tank into the pump and injectors — and the single most helpful thing you can do now isn't restart it. ## Is a fuel drain going to void my warranty? It's not an alteration, and so a drain then flush carried out properly does not 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 disagreement with one. ## Could I put some two-stroke in and just drive? Two-stroke oil solves a separate fault, and an old one at that. Nothing it does puts back what petrol thinned. No. Your tank still has petrol in it after that, and the pump still has to live with it. ## Main dealers and petrol in a diesel No. Our engineers drain and clean your car wherever it is, so there is no need to bring it to a franchised dealer. ## You, and your car, still together? Don't switch your engine on again. Switch it off somewhere safe then leave it off, if you have already driven it. A parked, cold motor is the best place to be in, and this is recoverable from a lot more regularly than motorists expect. Emptying misfuelled motors, Hurst Green and the rest of East Sussex, wherever they are. Kerbside. Forecourt. Home.
