Pause there. Petrol in a diesel that hasn't been run is typically a simple drain plus a flush, done right where the vehicle stands, and what you do in the next few minutes decides that far more than anything else. Below is the sequence from this point, anywhere in Kingston Hill you happen to be. ## Motor off: minute one with petrol in a diesel Go through these in sequence, first. - Keys out of the ignition. Switching the ignition on can be enough to prime your fuel system, while priming draws petrol out of your tank toward the components it damages. Leave the vehicle off altogether. - Don't top it up with diesel. Adding diesel takes out nothing. You end up with a fuller tank of the same mixture. - Get your car simple to see before anything else — hazards on — if there is traffic going past anywhere near you. - The attendants will usually help you push it away from the pump. Ask, then roll it by hand — never under the motor, even for a few yards. - The first thing we will ask is which fuel you put in and roughly how much — and the receipt says both. Keep it. Noticed on the move? Get off at the next junction if you're on the M4, under 5 miles from Kingston Hill, and stop somewhere sensible — not at the services further on. Stage one comes after that. ## Every Kingston Hill fuel drain starts here: has your engine run? Everything after this point rests on one answer. Motor not run at all? - Only that tank has petrol in it so far. - The job is a drain and a flush, normally done where the car is. - Being here is as good as it gets — which is the entire point of step one. If your engine has run, even briefly: - Some petrol has left the tank already, passed through the fuel filter, and reached your lines. - Run it farther and the petrol reaches the fuel injectors, having gone through your pump first. - Flushing your lines, your filter dealt with, occasionally more: this job expands as the distance does. The line falls there because diesel protects the high-pressure pump and the injectors on its way through them — and petrol doesn't. Nothing is damaged by petrol that's just waiting in a tank. Petrol being pumped is wearing the components that move the car. ## What to have ready when you call about petrol in a diesel from Kingston Hill Prepare a little, and the van finds you rather than circling. - Where you have stopped. A postcode starting KT2 7 is the best place to start. - Wherever you have pulled up, the road's name is useful — whether that's Queen's Road or somewhere else — and so does the name of a car park. - Car parks are located more easily by what they serve: tell us the one at Lidl, and it is easy. - That it is a diesel, along with the make and model of your car. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Kingston Hill page. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - Whether it's run. And if it has, how far plus how hard. - The owner may have to approve this work under some hire and company contracts — which is why it's faster to settle whose car it is before we arrive. Call 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use . ## The wait for a Kingston Hill fuel drain, and what to do in it Stick to these: well-meant help does the damage during the wait. - Where the car has stopped settles where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of the car. - A helpful passer-by doesn't crank it. Nor does anybody wanting to check it still works, or rolling it a couple of yards. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - Siphoning petrol into a can by the kerbside is hazardous — and it also leaves whatever fuel has already gone beyond your tank. Don't drain it yourself. - Leave the ignition off — your windows and the radio too. ## Van arrived? Your fuel drain, one stage at a time - Our price comes after three questions, not before them — what went in, how much, and whether it's run — since the answers decide the job. - Then your tank is cleared, so the tainted fuel is taken out. - The fuel lines are purged. If it ran, the petrol has moved beyond that tank, and the fuel lines are carrying it. - Cleaned, or replaced if the car has a serviceable one: your filter is sorted next. - Clean diesel in, and the fuel system primed. - We fire it up only after new diesel has gone in and bled the system, then check that it's running correctly. The car has fresh diesel running through it before we leave. Long-term damage is very unusual when it has been noticed quickly, so the vehicle can go right back to normal driving. ## After the fuel drain is done: driving around Kingston Hill again - After it's been started on fresh fuel, there's nothing special to do: drive normally. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over then call us back. - Keep your documents. A hire company, a fleet manager or an insurer may ask what was done. - Next time, trust the petrol pump's label rather than the colour of its handle. ## About Kingston Hill and where it is Kingston Hill is a suburban area in the Royal Borough of Kingston upon Thames, situated inland at an elevation of 22 metres.
