Pause there. Drained then rinsed, right where it sits: that is usually all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes ahead far more than on everything else. Below is the sequence from here, anywhere in Kensey Valley Meadow you are. ## Petrol in a diesel? What to do in minute one Before anything else, the following — following this sequence. - Ignition off, keys out. Switched on, the ignition can prime your system — and priming is what moves petrol out of the tank into the parts it damages. - A bigger tank of the same mix is all topping up leaves you, because it removes nothing. So no more diesel. - Being seen comes first near moving traffic: put your hazards on, and only then think about everything else. - Off the petrol pump by hand. On a forecourt, get the attendants to help you push it away from the petrol pump. Don't crank it to shift it, however short the way. - The first question we will ask is which fuel you put in and roughly how much — and the receipt says both. Keep it. Still on the move when you realised? Come off the M5 at the next junction if that is where you are, under 50 miles from Kensey Valley Meadow, and pull over somewhere safe instead of pressing on to the services. Then begin at step one. ## The fork in every Kensey Valley Meadow fuel drain: has it run yet? Everything after this point depends on one answer. Not run, not even once: - All the petrol sits in that tank, and only there. - Usually it's emptied and rinsed right where the vehicle stands. - This is the best spot to be in, and the whole reason step one counts. If the engine has been run, even for a moment: - Out of the tank, through your filter, into your lines: that is how far that petrol has got. - A bigger run carries it all the way to the high-pressure pump and the fuel injectors. - Lines flushed, the filter seen to, occasionally more: the job grows as the miles does. Why the line falls there: diesel lubricates the high-pressure pump and the fuel injectors as it passes through them, and petrol does not. Petrol sitting in a tank damages nothing. Pump that petrol, though, and it wears the very parts doing the moving. ## What to have prepared when you call about petrol in a diesel from Kensey Valley Meadow A little preparation is the difference between a van that finds you and a van that goes round. - Your location: a postcode beginning PL15 9 serves best. - Name the road — Kensey Court or wherever you have pulled up — or the car park. - Or the landmark. A car park is easier to find by what it serves, like the one at The Co-operative Food. - The vehicle. Make, model, plus that it's a diesel. - Which got in matters: AdBlue is a separate job from petrol, and Kensey Valley Meadow has a page for it. So say. - How long the nozzle was in, or the litres from your receipt — whichever tells us how much. - Whether it has run. And if it has, how far plus how hard. - Hire or company car? Some agreements want the owner's authorisation for the work, and sorting it before our engineers get there is faster than afterwards. Ring 0333 366 0103 next. Writing to works as well if it can wait, with your car left at home, going nowhere. ## Waiting for a fuel drain around Kensey Valley Meadow: what to do Hold to these: well-meant help causes the damage during the wait. - Your safety comes before the vehicle. Somewhere unsafe? Get away from the traffic then wait away from it. Fine where it is? Stay with it. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a few yards. - None of it takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - A DIY drain leaves your fuel already gone beyond that tank, and siphoning petrol by the road is dangerous too. - Keep the ignition off — your windows and your radio too. ## Van arrived? Your fuel drain, one stage at a time - Fuel, quantity, whether it's run: those replies decide the job, and that is why you get a price after them rather than before. - Out of the tank comes the contaminated mixture: that tank is emptied. - The fuel lines are purged. If it ran, that petrol has moved beyond the tank, and the fuel lines are carrying it. - The fuel filter is seen to. Cleared, or swapped where the vehicle has a usable one. - Clean diesel goes in, then the system is primed. - Starting the car. When the fuel system is bled with new diesel, we fire it up and make sure it runs properly. Our engineers wait until it is running on clean diesel. The car goes back to normal driving straight away, and lasting damage is very uncommon when it has been noticed quickly. ## Once your fuel drain is done: driving in Kensey Valley Meadow a second time - Started on fresh diesel, it asks nothing special of you. Just drive normally. - Watch the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle tells you to pull over and call us back. - The work may matter later with a hire company, an insurer or a fleet manager. Hold on to your documents. - Read the label on the pump next time, not the colour of its handle. ## About Kensey Valley Meadow Kensey Valley Meadow is a suburban area situated on the outskirts of Launceston in Cornwall, with the River Kensey running alongside.
