Pause; leave the vehicle off. Petrol in a diesel that hasn't been run is normally a simple drain plus a flush, done where your car sits, and what happens in the coming few minutes determines that more than anything else. From now on, step by step, for anywhere around Northwich: ## Petrol in a diesel, motor off — the first minute Work through these in sequence, before you do anything else. - The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what moves petrol out of your tank into the parts it harms. - A fuller tank of the same mixture is all adding diesel leaves you, since it takes out nothing. So no extra diesel. - Being seen comes before the rest near moving traffic: switch the hazard lights on, and only then deal with anything else. - However short the way, starting it to shift it is the thing to avoid. At a forecourt, roll the car clear of the pump by hand instead, and ask the attendants to lend a hand. - Hold on to the receipt. It says which fuel went in plus roughly how much, which is the first thing we will ask. Realised on the move? Get off at the next exit if you're on the M6, under 5 miles from Northwich, and stop somewhere sensible — not at the services further on. Stage one starts after that. ## The fork in each Northwich fuel drain: has it run yet? One answer is what everything after this stage rests on. If it has never been started: - The petrol is still inside that tank and nowhere else. - The work is a drain and a flush, normally done where the vehicle stands. - No place is better, and it's why the first step counts so much. Motor run, however briefly? - The fuel lines and your filter now carry petrol drawn from the tank. - Run it further and that petrol reaches the fuel injectors, having passed through the pump first. - The job expands with the miles — lines purged, filter dealt with, sometimes more. The reason the line falls there: diesel protects your high-pressure pump as well as the injectors as it flows through them, and petrol doesn't. In your tank, sitting still, petrol harms nothing. Pump that petrol, though, and it wears the very parts that move it. ## Calling about petrol in a diesel from Northwich: what to have prepared Prepare a little, and the van finds you rather than circling. - Your whereabouts: a postcode starting CW9 5 serves best. - A road name is a help: Watling Street, say, or whatever street you've stopped in. A car park does the trick too. - Car parks are located most easily by what they serve: tell us the one outside A-Z Convinence Store, and it's simple. - That it's a diesel, along with the make and model of the car. - Which got in counts: AdBlue is a separate job from petrol, plus Northwich has a page for it. So say. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - Has it run? If so, say how far it got, and how it was driven. - Settle who owns the vehicle ahead of when we turn up: some hire and company agreements want the owner to approve the work, and that is quicker first. Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick as well. ## The wait for a Northwich fuel drain, and what to do in it In the wait, the harm comes from well-meant help — so these matter. - Your safety comes before your car. Somewhere dangerous? Get away from the traffic then wait away from it. Fine where it stands? Wait with it. - A helpful passer-by does not start it. Nor does anybody wanting to check it still does the trick, or moving it a few yards. - Something from your boot, oil made for two-strokes or injector cleaner: no additive removes the petrol. - Siphoning petrol into a can at the roadside is dangerous — and it also leaves whatever fuel has already gone beyond that tank. Don't drain the car yourself. - Not for your radio, not for the windows: your ignition stays off. ## Van arrived? The fuel drain, one step at a time - Three queries. What went in, how much, and if it's run. Those replies decide this job, which is why our price comes after them but not before. - Next that tank is drained, so the contaminated fuel comes out. - Petrol that has moved beyond that tank travels in the lines if it ran, and the lines are flushed to shift it. - Then the fuel filter: swapped where there is a serviceable one, cleared where there is not. - The fuel system is primed on clean diesel. - Starting up. When your system is bled with fresh diesel, we fire it up and make sure it runs properly. Until it runs on new diesel, we remain with it. Long-term damage is very rare if it has been caught soon, so the vehicle can go straight back to normal driving. ## Once your fuel drain is done: driving around Northwich again - Drive normally. There is nothing special to do after it has been started on fresh fuel. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop and ring us a second time. - The work may come up later with a hire firm, an insurer or a fleet manager. Keep the documents. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Northwich itself Northwich is a town in Cheshire, situated on the banks of the River Weaver, with a mix of semi-detached housing and other residential areas.
