Petrol in a diesel that hasn't been run is generally a simple drain and a flush, done where the car stands, and what you do in the coming few minutes decides that far more than anything else. From now on, step by step, wherever you are around Rendlesham: ## Minute one: petrol in a diesel, engine off First, the following — following this order. - Pull the keys out. Even your ignition by itself can prime the system, pulling petrol out of the tank to exactly the components it damages, so leave the car alone entirely. - Topping up with diesel seems like it dilutes the problem. It doesn't: nothing comes out, and your tank just holds more of the same. - Close to moving traffic? Then the hazards go on before anything else, so the car is simple to spot. - Off the petrol pump by hand. At a forecourt, ask the staff to help you roll the vehicle away from the pump. Don't crank it to shift it, however short the way. - Keep the till receipt. It shows which fuel was put in plus about how much, which is the first thing we'll ask. On the M11, over 50 miles from Rendlesham, the next junction is the place to leave the car; anywhere, the first sensible spot to stop. Do not push on to the services. Then go back to step one. ## The fork in each Rendlesham fuel drain: has it run yet? What happens next rests on one answer, and only one. Motor not run at all? - The petrol remains in that tank, and just there. - A drain and flush, on the spot, is usually all of that. - This is as good as it gets — which is the whole point of stage one. If the engine has been run, even briefly: - Some petrol has left your tank already, gone through your filter, and got into your lines. - The high-pressure fuel pump as well as your injectors see it too on a bigger run. - The job grows with the miles — lines rinsed, filter dealt with, sometimes more. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it flows through, which is why the line sits where it does. A tank of petrol, left still, hurts nothing. Pump that petrol, though, and it wears the very parts that move it. ## Rendlesham, petrol in a diesel: have these ready before you call A little preparation is the difference between a van that finds you and a van that circles. - IP12 2 and the remainder of the postcode is the best way to start telling us where you are. - Wherever you have pulled up, the road's name helps — whether that is Suffolk Drive or somewhere else — and so does the name of a car park. - Car parks are located most easily by what they serve: tell us the one at Costcutter, and it is straightforward. - Tell us what the vehicle is — make, model — and check it's diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Rendlesham page. - How long the nozzle was in, or the litres from the receipt — whichever tells us how much. - The miles it did, and how heavily, if it has run at all. - Settle who owns the car ahead of when our technicians turn up: some hire or company contracts want the owner to approve this work, and doing it faster beforehand. Next, 0333 366 0103. Not time-critical, the vehicle left at home with nowhere to be? Then will do too. ## Rendlesham fuel drain on its way? While you wait The wait is where well-intended help does the harm. Hold to these. - Where the car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the vehicle. - Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a couple of yards. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - No home-made clearing. Siphoning petrol into a can by the kerbside is hazardous, and it leaves your fuel that has by now gone beyond the tank. - Not for your radio, not for the windows: your ignition stays off. ## Step by step: your fuel drain when the van arrives - First, three questions: which fuel got in, the amount, and has it run? Those replies decide the job, and so our price follows them. - Next the tank is emptied, and the polluted fuel is taken out. - Petrol that has shifted beyond your tank travels in your lines once it ran, and the lines are rinsed to clear it. - Cleaned, or replaced if the vehicle has a workable one: the filter is seen to next. - Fresh diesel in, and the system primed. - The first start on fresh diesel. Once bleeding is finished, the engine is fired up and we make sure that it runs properly. Our technicians remain until it's running on new diesel. It is very rare for a vehicle spotted early to be left with long-term damage, and normal driving resumes straight away. ## Back on the road around Rendlesham after your fuel drain - Nothing special is needed after a start with fresh diesel — normal driving will do. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle tells you to pull over and call us back. - An insurer, a fleet manager or a hire company may ask what was done, and so hold on to the paperwork. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Rendlesham and where it is Rendlesham is a village in Suffolk, situated in a rural area with nearby settlements including Friday Street, Eyke, and Spratts Street.
