Here Is What Happens Pause, then leave your engine off — not on, and not for a moment to shift the vehicle. Drained then flushed, just where it sits: that is normally all an unrun diesel with petrol in it takes. Whether it remains that simple depends on the minutes to come far more than on anything else. Here's the order of things from now, anywhere you are in Baybridge. ## Petrol in a diesel, motor off — the first minute Before anything else, these — in this order. - Priming the system pulls petrol from your tank towards the parts it damages, and turning your ignition on can be enough to do that. So the keys come out, and your ignition stays off completely. - No diesel on top. More fuel in removes none of the petrol — it just leaves you with extra of the same blend. - Being seen comes before the rest near moving traffic: put the hazards on, and only then deal with everything else. - By hand, not under the motor: that's how it comes off the petrol pump. Get the forecourt attendants to help you roll, however short the mileage. - Keep the receipt: the grade and the rough amount are written on it, and they're what we ask about first. If you were still driving when you noticed, pull over somewhere sensible rather than pushing on for the services — on the M3, under 5 miles from Baybridge, that means the next exit. Step one follows. ## Baybridge fuel drain: has your motor run yet, or not? Everything after this point depends on one answer. If the motor has not run at all: - The petrol remains inside the tank, and just there. - Normally it is drained and cleaned just where your car stands. - Step one matters for precisely this reason: it's the best position to be in. If the motor has run, even briefly: - Out of that tank, past the filter, into your lines: that's how far that petrol has got. - Run it further and the petrol reaches the injectors, having gone through the pump first. - Mileage is what makes it a larger job: flushed lines, a filter seen to, and at times further work. The reason the line falls there: diesel lubricates the high-pressure pump as well as the injectors as it flows through them, and petrol doesn't. Nothing is harmed by petrol that's just sitting in a tank. The parts that shift it are grinding the moment petrol is being pumped. ## Calling about petrol in a diesel from Baybridge: what to have prepared Get ready a little, and the van finds you rather than circling. - SO21 1 plus the rest of the postcode is the best way to begin telling us where you are. - The road or the car park. A road name is a help — Baybridge Lane, or wherever you have pulled up. - What a car park serves is the easiest way to find it, and so mention the landmark — such as the one outside Nisa Local. - The car. Make, model, plus that it is a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Baybridge, so tell us which. - How long the nozzle was in, or the litres on the receipt — either gives us how much. - Whether it's run. And if it has, how far and how hard. - Settle who has the vehicle before our technicians turn up: some hire or company contracts want the owner to authorise this work, and doing it quicker first. Then phone 0333 366 0103. If it can wait — your car is at home and going nowhere — works too. ## While you wait for a fuel drain in Baybridge The wait is where kindly meant help does the damage. Stick to these. - Stay with your car if it is safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - A helpful passer-by doesn't fire it up. Nor does anyone checking it still does the trick, or moving it a couple of yards. - None of that gets that petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank remains where it is anyway. - Not for the radio, not for your windows: your ignition remains off. ## When our van arrives: your fuel drain, step by step - Three questions. What was put in, how much, and whether it has run. The answers shape this job, which is why our price comes after them but not before. - Emptying it is how that blend gets taken from the tank. - If it ran, the lines are holding petrol that has shifted beyond the tank — so they're purged. - Cleaned, or replaced if your car has a serviceable one: the fuel filter is dealt with next. - Your system is primed with clean diesel. - Our engineers fire it up only after new diesel has gone in and primed the fuel system, then confirm that it's running smoothly. Your car has clean diesel running through it before we leave. It is very uncommon for a car caught quickly to be left with lasting damage, and normal use resumes straight away. ## After your fuel drain: back on the road in Baybridge - Nothing unusual is needed after a start with clean diesel — ordinary driving is all. - Watch the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over then ring us back. - The paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour is not the thing to go by next time — the label on the petrol pump is. ## About Baybridge, for a moment Baybridge is a small hamlet in Hampshire, situated inland at an elevation of 96 metres, approximately 4.7 miles from Winchester.
