Motor off. Leave the car that way — no moment on, no moving it anywhere. Emptied and purged, right where it sits: that's normally all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes ahead more than on everything else. From here on, step by step, for anywhere around Tower Hill: ## Petrol in a diesel, engine off — the first minute Go through these in order, before you do anything else. - Keys out of your ignition. Switching the ignition on can be all it takes to prime your fuel system, while priming draws petrol out of the tank toward the components it harms. Keep the car off completely. - Don't top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture. - Near moving traffic? Then the hazards go on before everything else, and so your car is simple to spot. - By hand, not on the motor: that's how it comes off the pump. Ask the forecourt attendants to help you push, however short the miles. - Hold on to the till receipt: the fuel and roughly how much are written on it, and they are what our engineers ask about first. Noticed on the move? Get off at the next junction if you are on the M6, under a mile from Tower Hill, and pull over somewhere safe — not at the services further on. Step one starts after that. ## Has it run yet? The fork in each Tower Hill fuel drain Everything after this stage depends on one answer. Engine not run at all? - The petrol is still in that tank and nowhere else. - Usually it's emptied and cleaned just where your car stands. - This is the best case — which is the entire point of stage one. If it's been started, even for a second: - Petrol has been pulled out of the tank, past your filter then into the fuel lines. - Run it farther and the petrol gets to your injectors, having gone through your fuel pump first. - The further it went, the bigger this job — the fuel lines, your filter, and sometimes more besides. Petrol doesn't lubricate. Diesel does, protecting your pump and injectors as it passes through, which is why the line sits where it does. In your tank, sitting still, petrol harms nothing. The parts that move it are wearing the moment petrol is being pumped. ## Calling about petrol in a diesel from Tower Hill: what to have prepared A little planning is the difference between a van that finds you and a technician that goes round. - Where you have stopped. A postcode starting B42 1 is the ideal start. - Wherever you have pulled up, the road's name helps — whether that's Beeches Road or somewhere else — and so does the name of a car park. - Describe a car park by what it serves — the one at The Co-operative Food, for instance — and it's much easier to find. - The make and model of the car, and the fact it is a diesel. - What went in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Tower Hill, and so tell us which. - The amount: your receipt's litres, or otherwise how long you held the nozzle in. - The mileage it did, and how hard, if it ran at all. - Whose car it is. Some hire and company agreements want the owner to authorise the work, and that is easier settled before our technicians turn up than after. Next, 0333 366 0103. Not urgent, the car left at home with nowhere to be? Then works too. ## The wait for a Tower Hill fuel drain, and what to do in it Hold to these: well-meant help causes the damage during the wait. - Wait with the car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll the car a few yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it takes that petrol back out. - A home-made drain leaves your fuel that has already gone beyond your tank, and siphoning petrol by the road is risky besides. - Ignition stays off. Even for your radio or your windows. ## Step by step: the fuel drain when our van gets there - First, three questions: which fuel got in, the volume, and has it run? Those replies shape this job, so the price follows them. - The tank is cleared. The contaminated mix comes from the tank. - Flushing the fuel lines comes next, because a motor that ran has petrol past that tank, in the fuel lines themselves. - Cleaned, or changed if the car has a serviceable one: the fuel filter is dealt with next. - The fuel system is primed with clean diesel. - The start. With new diesel in and the fuel system bled, it's started and tested to be sure it runs smoothly. Until it runs on clean diesel, our technicians remain with it. It is very unusual for a vehicle noticed soon to be left with long-term damage, and normal use resumes straight away. ## Tower Hill, after your fuel drain: back on the road - Drive normally. There is nothing unusual to do once it has been started on fresh fuel. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over and call us back. - The paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Check the label on the petrol pump next time, not the colour of its handle. ## About Tower Hill Tower Hill is a suburban area in the West Midlands, situated near the River Tame and close to the city of Birmingham.
