Drained then rinsed, just where it sits: that's generally all an unrun diesel with petrol in it takes. Whether it stays that straightforward depends on the minutes ahead more than on everything else. Wherever you are in Dudley, here is the order things go from now. ## Petrol in a diesel? What to do in minute one In this order, all before anything else: - Ignition off, keys out. Turned on, the ignition can prime your system — and priming is what draws petrol out of your tank into the parts it harms. - Do not top it up with diesel. Adding diesel takes out nothing. You are left with a bigger tank of the same mixture. - Hazard lights on. If you are at all near moving traffic, make the car easy to see before you do anything else. - By hand, not under the engine: that is how it comes off the petrol pump. Ask the forecourt staff to help you push, however short the miles. - Keep the receipt: the grade and the rough amount are written on it, and they're what our technicians ask for first. Realised on the move? Get off at the next junction if you're on the M5, under 3 miles from Dudley, and stop somewhere sensible — not at the services farther on. Step one comes after that. ## The fork in each Dudley fuel drain: has it run yet? Everything after this point rests on one answer. Not run, not even once: - The petrol is still inside the tank and nowhere else. - The job is a drain and a flush, normally done where the car stands. - Step one matters for precisely this reason: it is the best place to be in. Run at all, however briefly: - Your lines and the fuel filter now carry petrol pulled out of the tank. - The high-pressure fuel pump as well as the fuel injectors see it too on a longer run. - The job expands with the miles — lines cleaned, filter sorted, sometimes more. Petrol does not lubricate. Diesel does, oiling your high-pressure pump and injectors as it flows through, which is why the line sits where it does. In your tank, left alone, petrol harms nothing. The components that move it are wearing the moment petrol is being pumped. ## Dudley, petrol in a diesel: have these prepared before you call Whether the van circles or finds you depends on a little planning. - Your location: a postcode starting DY1 1 works best. - A road name is a help: High Street, say, or whichever street you have stopped in. A car park does the trick too. - Describe a car park by what it serves — the one at Sharif & Sons. Supermarket, for example — and it is much quicker to find. - The car. Make, model, plus that it is a diesel. - Tell us which was put in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Dudley. - How long the nozzle was in, or the litres from the receipt — either tells us how much. - If it's run, how far plus how heavily — as well as whether it's run at all. - The owner may have to approve the work under some hire and company contracts — which is why it's faster to settle whose car it is before our engineers arrive. Then phone 0333 366 0103. If it can wait — the car is at home with going nowhere — does the trick as well. ## Whilst you wait for a fuel drain around Dudley Hold to these: well-meant help does the damage during the wait. - Your safety comes before the vehicle. Somewhere dangerous? Get clear of the traffic then wait away from it. Fine where it sits? Wait with it. - A helpful passer-by does not start it. Nor does anyone wanting to check it still works, or moving it a few yards. - None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives. - A home-made drain leaves the fuel that has already gone beyond the tank, and siphoning petrol by the road is hazardous too. - Keep the ignition off — your windows and your radio included. ## When the van arrives: the fuel drain, step by step - Three queries. What got in, how much, and whether it's run. The answers set the job, which is why our quote comes after them but not before. - Draining it is how the blend gets taken out of that tank. - Petrol that has shifted beyond the tank travels in your lines if it ran, and the lines are rinsed to shift it. - The filter is seen to. Cleared, or swapped where the car has a workable one. - Clean diesel in, and the system primed. - We start the engine only after new diesel has gone in and bled your system, then check that it is running properly. Our engineers remain until it is running on new diesel. It's very unusual for a vehicle caught early to be left with permanent damage, and normal driving starts again at once. ## Dudley, after the fuel drain: back on the road - Once it's been started on fresh fuel, there's nothing unusual to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and call us once more. - Hold on to the paperwork. A hire company, a fleet manager or an insurer may ask what was done. - Check the label on the petrol pump next time, not the colour of its handle. ## About Dudley and where it is Dudley is a town in the West Midlands, situated on the River Dudley, with a mix of semi-detached housing and other residential areas.
