Here Is What Happens Whatever you do, never switch your engine on, even for a moment, to shift the vehicle. Stop; leave it off. Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your vehicle has stopped — and no other factor settles that more than these next few minutes do. Here's the order of things from now, wherever you are around Higher Compton. ## Petrol in a diesel? What to do in minute one Go through the following in order, before you do anything else. - Priming the fuel system pulls petrol from the tank toward the parts it damages, and switching the ignition on can be all it takes to do that. So your keys get taken out, and the ignition stays off completely. - Do not top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mix. - Hazard lights on. If you're anywhere near moving traffic, make the car simple to see before you do anything else. - Off the pump by hand. On a forecourt, ask the attendants to help you roll it clear of the pump. Don't fire it up to shift it, however short the distance. - Keep your receipt. It says which fuel went in and about how much, which is the first thing we'll ask. Still on the move when you noticed? Come off the M5 at the next exit if that's where you are, under 50 miles from Higher Compton, and pull over somewhere safe instead of pushing on to the services. Then start at step one. ## Every Higher Compton fuel drain starts here: has the motor run? What happens next turns on one answer, and just one. Not run, not even briefly: - The petrol sits inside your tank, and only there. - The work is a simple drain and a flush, normally done where the car stands. - No position is better, and it is why the first step counts so much. If your motor has run, even for a moment: - The fuel lines and your filter now carry petrol drawn out of the tank. - On a bigger run it has reached your high-pressure pump and your injectors. - Flushing your lines, the fuel filter sorted, occasionally more: the job grows as the mileage does. Diesel keeps the high-pressure pump and your injectors oiled as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. Nothing is harmed by petrol that is just sitting in a tank. As soon as it's pumped, petrol begins wearing whatever moves it. ## Higher Compton, petrol in a diesel: have these prepared before you call A little planning is the difference between a van that finds you and a van that goes round. - Where you are. A postcode beginning PL3 5 is the best place to start. - Wherever you have parked, the road's name helps — whether that's Eggbuckland Road 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 say the landmark — such as the one outside Morrisons Daily. - The vehicle. Make, model, and that it is a diesel. - Say which went in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Higher Compton. - The quantity: the receipt's litres, or otherwise how long you had the nozzle in. - If it's run, how far and how heavily — and if it's run at all. - Hire or company car? Some agreements need the owner's authorisation for the work, and sorting it before our technicians arrive is quicker than afterwards. Next, 0333 366 0103. Not urgent, the vehicle parked at home with nowhere to be? Then will do as well. ## While you wait for a fuel drain around Higher Compton During the wait, the harm comes from well-meant help — which is why these count. - Where the vehicle has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before your car. - A kind passer-by doesn't fire it up. Nor does anybody wanting to check it still works, or moving it a couple of yards. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of it gets that petrol back out. - A home-made drain misses your fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous too. - Even your radio or your windows are not worth switching the ignition on for. ## When the van arrives: your fuel drain, step by step - Our quote comes after three queries, not before them — what got in, how much, and if it has run — since the replies set the job. - Clearing it's how that blend gets taken from the tank. - Cleaning the lines follows, since a motor that ran has petrol past that tank, inside your lines themselves. - Where your car has a serviceable filter, it's replaced; otherwise, cleared. - Clean diesel in, and the fuel system primed. - The start-up. With fresh diesel in and the fuel system bled, it is started and tested to confirm it runs correctly. Till it runs on clean diesel, our engineers stay with it. It's very rare for a vehicle spotted early to be left with lasting damage, and normal use starts again right away. ## Once your fuel drain is done: driving in Higher Compton again - Drive normally. There is nothing special to do once it's been started on fresh fuel. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the 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 your paperwork. - Next time, trust the pump's label rather than the colour of its handle. ## About Higher Compton, for a moment Higher Compton is a suburban area located on the coast of Devon, near the city of Plymouth.
