Here Is What Happens Whatever you do, never switch your engine on, even briefly, to move the vehicle. Stop; leave the vehicle off. Petrol in a diesel that has not been run is normally a drain and a flush, done right where your car stands, and what you do in the coming few minutes settles that more than anything else. Here is the sequence of things from here, wherever you're in Walcot West. ## Minute one: petrol in a diesel, motor off Go through these in sequence, before you do anything else. - Bleeding your fuel system pulls petrol from the tank towards the components it harms, and switching the ignition on can be enough to do that. So the keys come out, and your ignition remains off altogether. - A bigger tank of the same mixture is all topping up gives you, since it removes nothing. So no extra diesel. - Make the car simple to see first — hazard lights on — if there is traffic going past anywhere near you. - However short the distance, starting it to move it is the mistake. At a forecourt, push the car away from the petrol pump by hand instead, and ask the staff to lend a hand. - Keep the receipt: the grade and roughly how much are printed on it, and they're what our technicians ask for first. If you were still driving when you noticed, pull over somewhere sensible rather than pushing on for the services — on the M4, under 3 miles from Walcot West, that means the next junction. Stage one follows. ## Each Walcot West fuel drain starts here: has the engine run? What comes next turns on one answer, and only one. If the motor has not run at all: - All the petrol remains in that tank, and just there. - Usually it's emptied and rinsed right where the car stands. - Stage one matters for exactly this reason: it's the best position to be in. Engine run, even for a moment? - The lines and the fuel filter now carry petrol pulled out of that tank. - Run it farther and that petrol reaches the fuel injectors, having gone through the fuel pump first. - Miles is what makes it a larger job: flushed lines, a filter seen to, and at times further work. Diesel keeps your high-pressure pump and the fuel injectors protected as it goes through them. Petrol gives them nothing, and that's why the line is drawn there. A tank of petrol, left alone, damages nothing. Petrol being pumped is grinding down the components that shift the car. ## Calling about petrol in a diesel from Walcot West: what to have prepared Prepare a little, and the van finds you rather than circling. - Your location: a postcode beginning SN1 3 works best. - A road name helps: Drove Road, say, or whichever street you have stopped in. A car park does the trick too. - Or the nearest landmark. A car park is easier to find by what it serves, such as the one at Aldi. - Make and model of the vehicle, and the fact it's a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Walcot West page. - About how much — in litres from the receipt, or by how long the nozzle was in. - The distance it covered, and how heavily, if it has run at all. - Settle who has the vehicle before our engineers get there: some hire and company contracts want the owner to authorise this work, and that is quicker first. Ring 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain in Walcot West: what to do Stick to these: well-intended help causes the damage during the wait. - Safety before the car. If it has stopped somewhere exposed, get yourself clear of the traffic then wait away from it. If it's safe where it stands, wait with it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's favour: nobody starts it. - Anything from the boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - No DIY emptying. Siphoning petrol into a can at the roadside is risky, and it leaves your fuel that has by now gone beyond that tank. - The ignition remains off. Even for your radio or the windows. ## Step by step: your fuel drain when the van gets there - Three queries. What went in, how much, and if it's run. The answers decide this job, which is why our quote comes after them and not before. - Your tank is cleared. The polluted mix comes out of the tank. - Cleaning the fuel lines follows, since a motor that ran has petrol past your tank, inside the lines themselves. - Cleared, or changed if the car has a usable one: the filter is dealt with next. - Clean diesel goes in, and the system is primed. - Starting the car. When the system is bled with fresh diesel, our engineers fire it up and make sure it runs properly. Until it runs on fresh diesel, we remain with it. It is very rare for a vehicle noticed soon to be left with lasting damage, and normal driving resumes straight away. ## After the fuel drain is done: driving in Walcot West once more - Drive normally. There's nothing special to do after it's been started on clean fuel. - Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over then ring us back. - Hold on to your paperwork. A hire firm, a fleet manager or an insurer may ask what was done. - The handle's colour isn't the guide to go by next time — the label on the petrol pump is. ## About Walcot West Walcot West is a suburban area in Wiltshire, situated inland at an elevation of 107 metres, with terraced housing being the predominant type of accommodation.
