Here Is What Happens Not for a second, and not to move it: the engine remains off. Stop there. Drained and purged, right where it is: that is usually all an unrun diesel with petrol in it takes. Whether it remains that straightforward rests on the minutes ahead far more than on everything else. Here's the sequence of things from now, wherever you're in Liberty Hill. ## Petrol in a diesel, engine off — the first minute Work through these before anything else, in this sequence. - Keys out of the ignition. Switching your ignition on can be all it takes to prime the fuel system, while priming draws petrol out of the tank toward the components it damages. Leave the vehicle off altogether. - A fuller tank of the same mix is all adding diesel gives you, since it takes out nothing. So no more diesel. - Hazard lights on. If you're anywhere near moving traffic, make the car easy to see before you do anything else. - The attendants will normally help you push it clear of the pump. Let them, and roll it by hand — never under the motor, even for a couple of yards. - Keep your receipt: the fuel and the rough amount are written on it, and they're what we ask for first. If you were still on the move when you noticed, stop somewhere sensible instead of pushing on for the services — on the M1, under 10 miles from Liberty Hill, that means the next junction. Step one comes next. ## Liberty Hill fuel drain: has your motor run yet, or not? From this point on, everything hinges on a single answer. Motor not run at all? - Just your tank has petrol in it so far. - Draining and flushing, on the spot, is usually the whole job. - Stage one counts for precisely this reason: it's the best place to be in. If your engine has run, even briefly: - From your tank, past the filter, into the fuel lines: that is how far the petrol has travelled. - Run it further and that petrol gets to the injectors, having gone through your pump first. - The further it went, the bigger the job — your lines, the fuel filter, and sometimes more besides. Diesel keeps the high-pressure fuel pump and your injectors lubricated as it goes through them. Petrol offers them nothing, and that's why the line is drawn there. Nothing is damaged by petrol that is just waiting in a tank. Petrol being pumped is grinding down the components that move the car. ## Calling about petrol in a diesel from Liberty Hill: what to have ready A little preparation is the difference between a technician that finds you and a technician that circles. - Your location: a postcode starting S6 5 works best. - Name the road — Fairbarn Way or wherever you have stopped — or the car park. - Or the nearest landmark. A car park is quicker to find by what it serves, such as the one at Co-op Food. - The vehicle. Make, model, plus that it's a diesel. - Which went in matters: AdBlue is a separate job from petrol, and Liberty Hill has a page for it. So say. - How much. Litres from your receipt, or how long the nozzle was in. - Has it run? If so, tell us how far it went, and how it was driven. - Settle who has the vehicle before our technicians arrive: some hire and company contracts want the owner to approve the work, and doing it faster beforehand. Then ring 0333 366 0103. If it can wait — your car is at home and going nowhere — works as well. ## Liberty Hill fuel drain on its way? Whilst you wait The wait is where well-intended help does the harm. Hold to these. - Your safety comes before the vehicle. Somewhere dangerous? Get away from the traffic then wait away from it. Fine where it is? Wait with it. - No one — however helpful — starts it, whether to see if it runs or to shift the car a short way. - Additives remain in the boot. Injector cleaner and two-stroke oil draw none of that petrol out once more. - No DIY emptying. Siphoning petrol into a can at the kerbside is dangerous, and it leaves the fuel that has already gone beyond your tank. - Even the radio or the windows aren't worth turning the ignition on for. ## Step by step: your fuel drain when the van arrives - Fuel, quantity, whether it has run: those answers set this job, and that's why you get a quote after them rather than before. - Out of your tank comes the polluted mixture: your tank is cleared. - The fuel lines are purged. If it ran, the petrol has shifted beyond that tank, and the lines are holding it. - Where your car has a usable filter, it is replaced; if not, cleared. - Fresh diesel in, and the system primed. - The start. With fresh diesel in and the system bled, it is fired up and tested to confirm it runs properly. We wait until it is running on fresh diesel. The vehicle goes back to normal use straight away, and permanent damage is very unusual if it has been spotted soon. ## Liberty Hill, after your fuel drain: back on the road - Started on clean diesel, it needs nothing unusual of you. Just drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over and ring us back. - Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, read the pump. The label, not the colour of the handle. ## About Liberty Hill Liberty Hill is a suburban area located on the riverside in South Yorkshire, with a mix of flat dwellings and a population of around 5474 residents.
