Motor off. Keep the vehicle that way — no second on, no shifting it at all. Petrol in a diesel that has not been run is normally a simple drain plus a flush, done where the car stands, and what happens in the next few minutes decides that more than anything else. What follows is the sequence from here, anywhere around Kingsbrook you happen to be. ## Petrol in a diesel, engine off — the first minute In this order, all before anything else: - Take the keys out. Even the ignition on its own can prime the system, pulling petrol out of the tank to exactly the parts it damages, so leave the car alone completely. - Topping up with diesel sounds like it dilutes the problem. It does not: nothing comes out, and your tank just holds more of the same. - Close to passing traffic? Then the hazards go on before everything else, so the car is simple to see. - However short the way, starting it to shift it is the mistake. On a forecourt, push it clear of the petrol pump by hand instead, then ask the attendants to lend a hand. - Hold on to your receipt: the grade and roughly how much are printed on it, and they're what we ask for first. Realised on the move? Get off at the next exit if you are on the M40, under 15 miles from Kingsbrook, and pull over somewhere safe — not at the services further on. Step one comes after that. ## Has it run yet? The fork in every Kingsbrook fuel drain Everything after this point rests on one answer. Motor never run at all? - No place but your tank: that's where that petrol still is. - The job is a simple drain and a flush, usually done where the car is. - No spot is better, and it's why the first step counts so much. Run at all, however briefly: - The fuel lines and the filter now hold petrol drawn from the tank. - Run it farther and that petrol reaches the injectors, having passed through the fuel pump first. - The farther it went, the larger this job — the fuel lines, your filter, and sometimes more besides. The reason the line falls there: diesel lubricates the high-pressure fuel pump and the injectors as it flows through them, and petrol doesn't. Petrol resting in a tank damages nothing. Move that petrol, though, and it wears the very parts that move it. ## Kingsbrook, petrol in a diesel: have these prepared before you call Whether the technician goes round or finds you comes down to a little planning. - Your location: a postcode starting HP22 5 works best. - Name the street — Bulrush Road or wherever you have stopped — or the car park. - Or the landmark. A car park is quicker to find by what it serves, such as the one outside Lidl. - The car. Make, model, plus that it is a diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Kingsbrook page. - How long the nozzle was in, or the litres from the receipt — either tells us how much. - The miles it covered, and how heavily, if it ran at all. - Hire or company car? Some agreements want the owner's go-ahead for this work, and sorting it before we turn up is faster than afterwards. Ring 0333 366 0103 once you've got that ready — or, if your car is at home, going nowhere, use . ## The wait for a Kingsbrook fuel drain, and what to do in it The wait is where well-meant help does the damage. Stick to these. - Where the car has stopped settles where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before your car. - A helpful passer-by doesn't crank it. Nor does anybody checking it still does the trick, or rolling it a few yards. - Additives remain in your boot. Injector cleaner and two-stroke oil draw none of the petrol out once more. - A DIY drain leaves the fuel that has already gone beyond that tank, and siphoning petrol by the road is hazardous besides. - Not for your radio, not for your windows: the ignition remains off. ## When our van gets there: your fuel drain, step by step - Three queries. What was put in, how much, and if it has run. The answers set this job, which is why our price comes after them but not before. - Emptying it's how that blend gets taken from your tank. - If it ran, your lines are holding petrol that has moved beyond that tank — so they're cleaned. - Cleaned, or changed if the vehicle has a serviceable one: your filter is dealt with next. - Bleeding the system comes once clean diesel is in. - The first start on fresh diesel. Once bleeding is complete, the motor is started and our engineers make sure that it runs correctly. Your car has new diesel running through it before we go. It's very rare for a car spotted quickly to be left with lasting damage, and normal use starts again right away. ## Back on the road around Kingsbrook after your fuel drain - Drive normally. There's nothing unusual to do after it's been started on clean fuel. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop then ring us once more. - Your documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, trust the petrol pump's label rather than the colour of its handle. ## About Kingsbrook itself Kingsbrook is a suburban area in Buckinghamshire, situated inland at an elevation of around 85 metres.
