Pause there. Has not been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever your car has stopped — and no other factor decides that more than these next few minutes do. Here's the sequence of things from here, anywhere you're in Whitehill. ## Petrol in a diesel? What to do in minute one Do these before anything else, in this order. - The ignition off, keys out. Turned on, your ignition can prime the system — and priming is what moves petrol out of your tank towards the components it harms. - Don't top it up with diesel. Adding diesel removes nothing. You are left with a fuller tank of the same mixture. - Hazard lights on. If you're anywhere close to moving traffic, make your car easy to see before you do anything else. - However short the way, starting it to move it is the mistake. On a forecourt, roll it away from the petrol pump by hand instead, then ask the staff to help. - The first thing you will be asked is which fuel you put in and about how much — and the till receipt shows both. Hold on to it. On the M3, under 15 miles from Whitehill, the next exit is the place to leave it; anywhere, the first sensible spot to stop. Don't press on to the services. Then go back to stage one. ## The fork in each Whitehill fuel drain: has it run yet? From this stage on, everything hinges on a single answer. Motor not run at all? - All the petrol remains in your tank, and just there. - A drain and flush, on the spot, is usually all of it. - No place is better, and it is why the first stage counts so much. If the engine has run, even for a moment: - Petrol has been pulled out of your tank, past your filter then into the fuel lines. - The high-pressure fuel pump and the fuel injectors see it too on a longer run. - Lines flushed, the filter dealt with, occasionally more: the job expands as the distance does. Why the line falls there: diesel protects the high-pressure fuel pump and your injectors as it flows through them, and petrol does not. A tank of petrol, left alone, damages nothing. As soon as it is pumped, petrol begins grinding whatever moves it. ## Calling about petrol in a diesel from Whitehill: what to have prepared Whether the van goes round or finds you depends on a little planning. - GU35 9 plus the rest of the postcode is the best way to start telling us where you are. - A road name helps: Petersfield Road, say, or whichever street you've stopped in. A car park works too. - Car parks are found most easily by what they serve: tell us the one at Tesco, and it is straightforward. - The car. Make, model, plus that it's a diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Whitehill page. - How long the nozzle was in, or the litres from the receipt — either tells us how much. - The distance it covered, and how heavily, if it has run at all. - Sort who owns the vehicle before our engineers turn up: some hire and company contracts want the owner to approve this work, and doing it faster first. Next, 0333 366 0103. Not time-critical, the vehicle left at home with nowhere to be? Then will do as well. ## Whitehill fuel drain on its way? While you wait Hold to these: well-meant help does the damage during the wait. - Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the car. - No one — however kind — starts it, whether to see if it runs or to move your car a short way. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that takes the petrol back out. - A DIY drain misses your fuel that has already gone beyond that tank, and siphoning petrol by the road is risky too. - Leave the ignition off — your windows and the radio too. ## When our van arrives: the fuel drain, step by step - Fuel, quantity, whether it's run: the replies decide this job, and that's why you get a price after them rather than before. - That tank is cleared. The tainted mixture comes from that tank. - Your lines are cleaned. If it ran, the petrol has moved beyond that tank, and the lines are holding it. - The filter is dealt with. Cleared, or replaced where the vehicle has a workable one. - Clean diesel goes in, then your system is primed. - Our engineers start the engine only after clean diesel has gone in and bled the fuel system, then check that it's running correctly. Until it runs on fresh diesel, we remain with it. The car goes back to normal driving right away, and long-term damage is very unusual when it has been noticed soon. ## Whitehill, after the fuel drain: back on the road - Drive normally. There's nothing unusual to do once it has been started on clean fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle stumbling: pull over and ring us back. - The documents answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Next time, go by the pump's label rather than the colour of its handle. ## About Whitehill, briefly Whitehill is a village in Hampshire, situated inland at an elevation of 96 metres, and is located near the villages of Hollywater and Blackmoor.
