Here Is What Happens Stop, then leave the engine off — not on, and not for a moment to move the car. Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever the car has stopped — and nothing settles that as much as the next few minutes do. Here's the order of things from now, anywhere you are in Warbstow. ## Minute one: petrol in a diesel, engine off First, these — in this sequence. - Keys out of your ignition. Switching your ignition on can be enough to prime your fuel system, while priming draws petrol out of the tank toward the parts it harms. Keep it off altogether. - No diesel on top. More fuel in takes away none of that petrol — it just leaves you with extra of the same blend. - Get the car simple to see first — hazard lights on — if there's traffic going past anywhere close to you. - The attendants will generally help you roll it clear of the pump. Let them, then move it by hand — not on the engine, even for a few yards. - Which fuel, and roughly how much? The receipt replies both, and that is where our first question starts. Never bin it. Realised on the move? Get off at the next exit if you are on the M5, under 50 miles from Warbstow, and stop somewhere safe — not at the services farther on. Step one starts after that. ## The fork in each Warbstow fuel drain: has it run yet? Everything after this stage depends on one answer. If the engine has not run at all: - Nowhere but your tank: that's where the petrol yet is. - Where your car stands is normally where the work happens: a drain, then a flush. - Stage one counts for precisely this reason: it is the best position to be in. Run at all, even for a second: - Petrol has been pulled from the tank, through your filter then into the lines. - On a longer run it has got to your high-pressure pump as well as the injectors. - The farther it went, the larger the job — your lines, the fuel filter, and sometimes more besides. Diesel keeps your high-pressure pump and the fuel injectors lubricated as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. In your tank, sitting still, petrol does no harm. Pump that petrol, though, and it wears the very parts doing the moving. ## Warbstow, petrol in a diesel: have these prepared before you call A technician that circles versus a van that finds you: a little preparation is the difference. - Your location: a postcode beginning PL15 8 works best. - The street or the car park. A road name helps — Knapmedown, or wherever you have pulled up. - Name a car park by what it serves — the one at the local shops, for example — and it is much easier to find. - Say what your vehicle is — make, model — and check it's diesel. - What went in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Warbstow, so tell us which. - The amount: the receipt's litres, or otherwise how long you had the nozzle in. - Has it run? If so, say how far it got, and the way it was driven. - The owner may have to authorise the work under some hire or company agreements — so it's faster to settle whose car it is before our engineers arrive. Call 0333 366 0103 once you've got that ready — or, if your car is at home, going nowhere, use . ## Waiting for a fuel drain in Warbstow: what to do The wait is where well-intended help does the harm. Hold to these. - Stay with your car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - No one — however kind — starts it, whether to see if it runs or to move the car a short way. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out a second time. - No home-made clearing. Siphoning petrol into a can by the kerbside is dangerous, and it leaves your fuel that has by now gone beyond the tank. - Not for the radio, not for the windows: your ignition stays off. ## The fuel drain, step by step, once the van gets there - Our quote comes after three questions, not before them — what was put in, how much, and whether it's run — since the replies shape this job. - Out of that tank comes the contaminated blend: that tank is drained. - The fuel lines are cleaned. If it ran, the petrol has shifted beyond the tank, and the fuel lines are carrying it. - Where your car has a workable filter, it is swapped; otherwise, cleared. - Clean diesel goes in, and the fuel system is primed. - The start. With fresh diesel in and the system bled, it is fired up and tested to make sure it runs correctly. Until it runs on clean diesel, our technicians remain with it. The vehicle goes back to normal driving right away, and permanent damage is very unusual when it has been caught soon. ## After your fuel drain is done: driving in Warbstow once more - Drive normally. There is nothing special to do after it's been started on clean fuel. - Pull over and ring us back if anything looks wrong early on — a light on the dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - Your documents covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Next time, read the petrol pump. The label, not the colour of the handle. ## About Warbstow itself Warbstow is a small village in inland Cornwall, situated at an elevation of 184 metres and comprising predominantly detached housing.
