Motor off. Leave it that way — no second on, no shifting it anywhere. Petrol in a diesel that hasn't been run is usually a simple drain plus a flush, done right where your vehicle stands, and what happens in the coming few minutes decides that far more than anything else. From here on, in order, wherever you are in Cranbrook: ## Petrol in a diesel, engine off — the first minute Work through these in order, first. - The ignition off, keys out. Switched on, the ignition can prime the system — and priming is what moves petrol out of the tank towards the parts it damages. - Don't top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mix. - Hazard lights on. If you are anywhere close to moving traffic, make your car simple to see before you do anything else. - By hand, not under the motor: that is how it comes off the petrol pump. Ask the forecourt attendants to help you push, however short the distance. - The first question you will be asked is which fuel you put in and about how much — and the till receipt says both. Hold on to it. If you were still driving when you realised, stop somewhere sensible instead of pushing on for the services — on the M20, under 15 miles from Cranbrook, that means the next exit. Stage one follows. ## Cranbrook fuel drain: has your engine run yet, or not? From this point on, everything hinges on a single answer. Engine not run at all? - That petrol is still in your tank and nowhere else. - Draining and flushing, on the spot, is usually the whole job. - No spot is better, and it's why the first stage counts so much. If it has been started, even for a second: - Some petrol has left that tank by now, gone through the fuel filter, and reached the lines. - On a longer run it has reached the high-pressure fuel pump and the fuel injectors. - The job grows with the distance — lines cleaned, filter seen to, occasionally more. Petrol doesn't lubricate. Diesel does, oiling the high-pressure pump and injectors as it flows through, which is why the line sits where it does. Nothing is harmed by petrol that is just resting in a tank. Pump the petrol, though, and it grinds down the very parts that move it. ## Before you call about petrol in a diesel around Cranbrook: what our technicians need Get ready a little, and the van finds you rather than circling. - The best start is a postcode — one beginning TN17 3 — for where you are. - Name the street — High Street or wherever you have pulled up — or the car park. - What a car park serves is the quickest way to find it, and so say the landmark — such as the one outside The Co-operative Food. - The car. Make, model, plus that it's a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Cranbrook page. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - If it has run, how far and how hard — and whether it has run at all. - Sort who owns the car ahead of when our engineers get there: some hire or company contracts want the owner to authorise the work, and doing it quicker first. Then call 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick too. ## The wait for a Cranbrook fuel drain, and what to do in it The wait is where well-intended help does the damage. Hold to these. - Where the vehicle has stopped settles where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the car. - Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: nobody starts it. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that gets that petrol back out. - No DIY emptying. Siphoning petrol into a can at the kerbside is risky, and it leaves your fuel that has by now gone beyond that tank. - Even your radio or the windows aren't worth turning the ignition on for. ## Van arrived? Your fuel drain, one step at a time - Three queries. What was put in, how much, and if it's run. The answers shape this job, which is why our price comes after them but not before. - Then your tank is emptied, so the contaminated fuel is taken out. - Rinsing the lines follows, because a vehicle that ran has petrol past your tank, in your lines themselves. - Cleared, or replaced if the car has a serviceable one: the fuel filter is sorted next. - Clean diesel in, and the system primed. - The start-up. With new diesel in and the system primed, it is fired up and checked to make sure it runs properly. Only when it's running on new diesel do our technicians head off. Your car returns to normal driving at once, and permanent damage is very uncommon when it has been caught early. ## Back on the road in Cranbrook after your fuel drain - Drive normally. There's nothing special to do once it's been started on clean fuel. - Pull over and call us back if anything looks wrong early on — a light on the dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - The paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Read the label on the pump next time, not the colour of the handle. ## About Cranbrook and where it is Cranbrook is a village situated in the Weald of Kent, on the River Crane, with a mix of semi-detached housing and older buildings.
