Pause; leave the car off. The next few minutes settle it far more than anything else: petrol in a diesel still unrun normally amounts to draining then flushing, right there. From now on, step by step, wherever you are in Haslemere: ## Petrol in a diesel, motor off — the first minute Work through these before anything else, in this sequence. - Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what moves petrol out of your tank towards the components it damages. - Topping up with diesel sounds like it thins the trouble. It does not: nothing comes out, and that tank just carries more of the same. - Near passing traffic? Then the hazards go on before everything else, and so the car is simple to spot. - However short the way, starting it to move it is the mistake. On a forecourt, roll the car away from the petrol pump by hand instead, and ask the attendants to help. - The first question we will ask is which fuel went in and about how much — and your receipt shows both. Hold on to it. Still on the move when you noticed? Come off the M3 at the next junction if that is where you are, under 25 miles from Haslemere, and pull over somewhere sensible rather than pressing on to the services. Then start at step one. ## Haslemere fuel drain: has the motor run yet, or not? From this stage on, everything comes down to a single answer. Engine never run at all? - Only your tank has petrol in it for now. - Where the car stands is normally where this work is done: a drain, then a flush. - Stage one counts for precisely this reason: it is the best place to be in. If the engine has run, even briefly: - Out of your tank, through the fuel filter, into your lines: that's how far the petrol has travelled. - Run it farther and that petrol gets to the injectors, having gone through the fuel pump first. - Distance is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work. Why the line falls there: diesel lubricates the high-pressure pump and the fuel injectors as it flows through them, and petrol doesn't. In your tank, left alone, petrol harms nothing. Move the petrol, though, and it grinds down the very parts that move it. ## Before you call about petrol in a diesel in Haslemere: what we need Prepare a little, and the technician finds you rather than circling. - GU27 2 and the remainder of the postcode is the best way to start telling us where you are. - Wherever you have parked, the road's name helps — whether that's High Street or somewhere else — and so does the name of a car park. - What a car park serves is the easiest way to find it, so say the landmark — such as the one outside Waitrose. - Make and model of your car, and the fact it's a diesel. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Haslemere, so say which. - The amount: the receipt's litres, or otherwise how long you had the nozzle in. - Has it run? If so, tell us how far it got, and the way it was driven. - The owner may have to authorise the work under some hire and company contracts — so it's quicker to settle whose car it is before we get there. Then ring 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — works as well. ## The wait for a Haslemere fuel drain, and what to do in it Help, however well meant, is what does the harm while you wait. So hold to these. - Safety before your car. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it's safe where it is, wait with it. - A helpful passer-by does not start it. Nor does anyone wanting to check it still works, or rolling it a couple of yards. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of that gets the petrol back out. - A DIY drain leaves the fuel already gone beyond that tank, and siphoning petrol by the road is hazardous besides. - Not for your radio, not for the windows: the ignition stays off. ## Step by step: your fuel drain when our van gets there - Fuel, amount, whether it's run: the replies set this job, and that's why we give a price after them instead of before. - The tank is drained. The polluted mix comes from your tank. - If it ran, the fuel lines are carrying petrol that has shifted beyond that tank — so they are purged. - Cleaned, or swapped if the car has a serviceable one: your filter is sorted next. - Fresh diesel in, and the system primed. - The first start on fresh diesel. When priming is complete, the engine is started and our engineers confirm that it runs correctly. Only once it's running on fresh diesel do we leave. It is very uncommon for a car noticed quickly to be left with permanent damage, and normal use starts again at once. ## After the fuel drain: back on the road in Haslemere - Nothing unusual is needed after a start with clean diesel — usual driving will do. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over then ring us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so keep the documents. - Next time, trust the pump's label rather than the colour of its handle. ## About Haslemere and where it is Haslemere is a town in Surrey, situated in the South East of England, approximately 38 miles from London.
