Engine off. Keep the car like that — no second on, no shifting it at all. Petrol in a diesel that hasn't been run is normally a simple drain plus a flush, done right where the car sits, and what happens in the next few minutes determines that more than anything else. Here's the order of things from now, anywhere you are in Crampmoor. ## Engine off: minute one with petrol in a diesel Do these before anything else, in this sequence. - Ignition off, keys out. Turned on, the ignition can prime your system — and priming is what draws petrol out of your tank into the components it harms. - Topping up with diesel seems like it dilutes the problem. It doesn't: nothing gets out, and your tank just carries more of the same. - Close to passing traffic? Then your hazards come on before everything else, and so the car is easy to spot. - The staff will normally help you roll it clear of the pump. Ask, then roll it by hand — not on the motor, even for a few yards. - The first question we will ask is which fuel went in and roughly how much — and the receipt says both. Keep it. Still driving when you realised? Come off the M27 at the next junction if that is where you are, under 3 miles from Crampmoor, and stop somewhere safe and not pushing on to the services. Then begin at step one. ## The fork in every Crampmoor fuel drain: has it run yet? One answer is what everything after this stage rests on. Motor never run at all? - Only the tank has petrol in it so far. - The job is a simple drain and a flush, usually done where the vehicle stands. - Step one counts for exactly this reason: it's the best place to be in. If the engine has been run, even for a moment: - From that tank, through the fuel filter, into the lines: that is how far that petrol has travelled. - A bigger run takes it right through to your high-pressure pump and the injectors. - Lines flushed, your filter dealt with, and sometimes more: this job grows as the distance does. Petrol does not lubricate. Diesel does, oiling the pump and injectors as it passes through, which is why the line sits where it does. In the tank, sitting still, petrol harms nothing. Once it's pumped, petrol begins grinding whatever moves it. ## Calling about petrol in a diesel from Crampmoor: what to have prepared Prepare a little, and the van finds you instead of circling. - Where you are. A postcode beginning SO51 9 is the best start. - Wherever you have parked, the road's name is useful — whether that is St Swithun's Close or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, so mention the landmark — like the one at Waitrose. - The make and model of the car, and the fact it's a diesel. - Which got in counts: AdBlue is a separate job from petrol, and Crampmoor has a page just for that. So say. - How much. Litres from your receipt, or how long the nozzle was in the filler. - Whether it's run. Then if it has, how far plus how hard. - The owner may have to authorise this work under some hire and company contracts — so it's faster to settle whose vehicle it is before we get there. Ring 0333 366 0103 next. Writing to is fine as well if it can wait, with the vehicle left at home, going nowhere. ## While you wait for a fuel drain in Crampmoor In the wait, the damage comes from well-meant help — which is why these matter. - Where your car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the vehicle. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a few yards. - Anything from the boot, oil made for two-strokes or injector cleaner: no additive removes that petrol. - No DIY emptying. Siphoning petrol into a can at the roadside is dangerous, and it leaves your fuel that has already gone beyond your tank. - Even the radio or the windows aren't worth turning your ignition on for. ## Van arrived? Your fuel drain, one stage at a time - Fuel, amount, whether it's run: the answers set the job, and that's why you get a quote after them rather than before. - Next that tank is cleared, and the polluted fuel is taken out. - The lines are rinsed. If it ran, the petrol has shifted beyond that tank, and your lines are holding it. - Then the filter: changed where there's a workable one, cleared where there is not. - Fresh diesel in, and your system primed. - First start on fresh diesel. When bleeding is finished, the engine is started and our technicians confirm that it runs smoothly. Until it runs on clean diesel, we stay with it. Lasting damage is very rare if it has been caught quickly, so the car can go right back to normal use. ## After your fuel drain: back on the road around Crampmoor - Nothing special is needed after a start with fresh diesel — ordinary driving is all. - Watch the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle tells you to pull over then call us back. - Hold on to the documents. A hire company, a fleet manager or an insurer may ask what was done. - The handle's colour isn't the guide to go by next time — the label on the petrol pump is. ## About Crampmoor and where it is Crampmoor is a village situated on the riverside in Hampshire, with a low elevation of around 25 metres.
