Petrol in a diesel that hasn't been run is typically a simple drain plus a flush, done where the vehicle sits, and what you do in the next few minutes determines that more than anything else. Wherever you are in Castlecroft, this is the order things go from now. ## Petrol in a diesel? What to do in minute one Do the following first, in this sequence. - Keys out of your ignition. Turning your ignition on can be all it takes to prime the system, while priming draws petrol out of the tank towards the components it harms. Leave the car off altogether. - Topping up with diesel sounds like it thins the trouble. It does not: nothing gets out, and the tank simply carries more of the same. - Hazard lights on. If you're anywhere near moving traffic, make your car easy to see before you do anything else. - However short the distance, starting it to move it is the thing to avoid. On a forecourt, push it clear of the petrol pump by hand instead, then ask the staff to help. - Which fuel, and roughly how much? The receipt replies that, and that is where our questions start. Never throw it away. Still on the move when you realised? Come off the M54 at the next junction if that is where you are, under 5 miles from Castlecroft, and pull over somewhere safe and not pushing on to the services. Then begin at step one. ## Has it run yet? The fork in each Castlecroft fuel drain What comes next rests on one answer, and just one. Engine not run at all? - Only the tank has petrol in it for now. - The job is a simple drain and a flush, usually done where the car stands. - This, here, is the best spot to be in, and the reason step one counts. Run at all, even for a second: - Petrol has been drawn from the tank, past your filter and into your lines. - The high-pressure pump and the injectors get it on a bigger run. - Mileage is what turns it into a larger job: the lines flushed, a filter seen to, and at times more than that. Diesel keeps your high-pressure pump and the injectors oiled as it goes through them. Petrol gives them nothing, and that is why the line is drawn there. In that tank, left alone, petrol harms nothing. The parts that shift it are grinding the moment petrol is being pumped. ## Castlecroft, petrol in a diesel: have these ready before you call Whether the van goes round or finds you comes down to a little preparation. - Where you are. A postcode beginning WV3 8 is the best start. - Wherever you have parked, the road's name helps — whether that's Castlecroft Avenue or somewhere else — and so does the name of a car park. - Describe a car park by what it serves — the one outside Lidl, for instance — and it is much quicker to find. - Say what the vehicle is — make, model — and check it's diesel. - What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Castlecroft, and so tell us which. - How much. Litres from the receipt, or how long the nozzle was in. - If it's run, how far plus how heavily — as well as if it's run at all. - Whose vehicle it is. Some hire or company agreements want the owner to authorise this work, and that is quicker settled before our engineers turn up than after. Then phone 0333 366 0103. If it can wait — your car is at home and going nowhere — works as well. ## Waiting for a fuel drain in Castlecroft: what to do The wait is where kindly meant help does the harm. Stick to these. - Where your car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the car. - Not to roll it a couple of yards, not to check it is all right, not for a passer-by's kindness: nobody starts it. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of it gets that petrol back out. - No DIY emptying. Siphoning petrol into a can at the roadside is dangerous, and it leaves the fuel that has already gone beyond your tank. - Even the radio or the windows aren't worth turning the ignition on for. ## The fuel drain, step by step, once our van arrives - Three queries. What went in, how much, and whether it's run. The replies shape this job, which is why the price comes after them but not before. - Next your tank is cleared, so the tainted fuel comes out. - If it ran, the lines are carrying petrol that has moved beyond your tank — so they're cleaned. - Cleaned, or swapped if the car has a serviceable one: your filter is seen to next. - Bleeding the system follows after fresh diesel is in. - The first start on new diesel. Once bleeding is complete, the motor is started and our engineers confirm that it runs smoothly. Only when it is running on fresh diesel do our engineers head off. It is very uncommon for a vehicle spotted early to be left with permanent damage, and normal use resumes right away. ## After your fuel drain: back on the road in Castlecroft - After it's been started on clean fuel, there's nothing special to do: drive normally. - Pull over and call us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so keep your paperwork. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Castlecroft Castlecroft is a suburban area located on the outskirts of Wolverhampton, near the River Staffordshire, with an elevation of around 116 metres.
