Motor off. Keep it like that — no moment on, no moving it at all. Emptied and rinsed, right where it sits: that is generally all an unrun diesel with petrol in it needs. Whether it stays that straightforward depends on the minutes to come far more than on everything else. From here on, step by step, for anywhere around Guston: ## Petrol in a diesel, engine off — the first minute In this sequence, and before anything else: - The keys out of the ignition. Turning your ignition on can be enough to prime your fuel system, while priming pulls petrol out of your tank towards the components it damages. Keep the vehicle off altogether. - No diesel on top. More fuel in removes none of that petrol — it just leaves you with more of the same mixture. - Close to passing traffic? Then your hazards go on before anything else, so your car is easy to see. - Off the petrol pump by hand. On a forecourt, ask the attendants to help you push it away from the petrol pump. Do not crank it to move it, however short the way. - Which fuel, and roughly how much? The receipt replies that, and that is where our first question starts. Never throw it away. Noticed on the move? Get off at the next junction if you're on the M20, under 10 miles from Guston, and pull over somewhere sensible — not at the services farther on. Stage one starts after that. ## Every Guston fuel drain starts here: has your engine run? Everything after this point depends on one answer. If it has not once been started: - That petrol is still inside your tank and nowhere else. - Where the car stands is usually where this work is done: a drain, then a flush. - No spot is better, and it is why the first stage counts so much. If it has been started, even for a second: - The fuel lines and your filter already carry petrol pulled from the tank. - A bigger run takes it right through to your high-pressure pump and your injectors. - The job grows with the miles — lines flushed, filter seen to, occasionally more. Petrol doesn't lubricate. Diesel does, oiling your high-pressure pump and injectors as it flows through, which is why the line falls where it does. A tank of petrol, left alone, hurts nothing. Move the petrol, though, and it grinds down the very parts doing the moving. ## Before you call about petrol in a diesel around Guston: what our engineers need Whether the van circles or finds you comes down to a little preparation. - Where you have stopped. A postcode beginning CT15 5 is the best place to start. - Name the street — The Street or wherever you have pulled up — or the car park. - What a car park serves is the quickest way to find it, so mention the landmark — like the one outside Lidl. - That it's a diesel, along with the make and model of your car. - Tell us which got in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Guston. - The quantity: the receipt's litres, or otherwise how long you had the nozzle in. - Whether it has run. Then if it has, how far plus how hard. - Settle who has the car ahead of when our engineers get there: some hire or company agreements want the owner to approve this work, and that is quicker beforehand. Then ring 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick as well. ## Waiting for a fuel drain around Guston: what to do Hold to these: well-intended help causes the damage during the wait. - Your safety comes before the vehicle. Somewhere exposed? Get clear of the traffic then wait away from it. Fine where it stands? Stay with it. - A kind passer-by does not fire it up. Nor does anybody wanting to check it still does the trick, or moving it a few yards. - None of it gets the petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - No home-made draining. Siphoning petrol into a can by the kerbside is risky, and it leaves the fuel that has by now gone beyond that tank. - Keep the ignition off — the windows and your radio included. ## Step by step: your fuel drain when our van gets there - First, three queries: which fuel went in, the amount, and has it run? Those answers set the job, and so our price follows them. - Emptying it is how the blend gets taken from your tank. - The lines are purged. If it ran, that petrol has shifted beyond your tank, and the lines are carrying it. - Then the fuel filter: replaced where there is a usable one, cleared where there is not. - Fresh diesel goes in, and the fuel system is primed. - Our engineers fire it up only after new diesel has gone in and bled your system, then make sure that it's running correctly. Our engineers stay until it is running on clean diesel. Lasting damage is very rare when it has been caught quickly, so the vehicle can go right back to normal use. ## Guston, after the fuel drain: back on the road - Drive normally. There's nothing unusual to do after it has been started on fresh fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over and ring us back. - An insurer, a fleet manager or a hire company may ask what was carried out, and so keep the paperwork. - The handle's colour isn't the thing to go by next time — the label on the pump is. ## About Guston, briefly Guston is a small village in Kent, situated near the coast and overlooking the English Channel.
