Petrol in a diesel that hasn't been run is normally a drain and a flush, done where the car stands, and what you do in the next few minutes settles that far more than anything else. Wherever you happen to be in Iver, here is the order things go from now. ## Minute one: petrol in a diesel, engine off Do the following before anything else, in this sequence. - Ignition off, keys out. Turned on, the ignition can prime the system — and priming is what draws petrol out of your tank towards the parts it harms. - Topping up with diesel sounds like it dilutes the trouble. It does not: nothing gets out, and your tank just holds more of the same. - Hazards on. If you are at all near moving traffic, make the vehicle simple to see before you do anything else. - The staff will generally help you push it clear of the petrol pump. Ask, and roll it by hand — never on the motor, even for a few yards. - Which fuel, and roughly how much? Your receipt replies that, and that's where our questions start. Never throw it away. If you were still driving when you realised, stop somewhere sensible instead of pushing on for the services — on the M25, under a mile from Iver, that means the next exit. Stage one follows. ## Has it run yet? The fork in each Iver fuel drain One answer is what everything after this point rests on. Not run, not even once: - The petrol remains in your tank, and just there. - A drain and flush, on the spot, is usually all of that. - Step one counts for precisely this reason: it's the best spot to be in. If the engine has run, even for a moment: - From that tank, past the fuel filter, into the lines: that is how far the petrol has got. - Your high-pressure pump as well as your injectors get it on a longer run. - Mileage is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work. Petrol does not lubricate. Diesel does, protecting your pump and injectors as it passes through, which is why the line falls where it does. Petrol resting in a tank harms nothing. The components that move it are grinding the moment petrol is being pumped. ## Calling about petrol in a diesel from Iver: what to have ready Get ready a little, and the van finds you rather than circling. - Where you have stopped. A postcode starting SL0 9 is the ideal start. - A road name is a help: Bangors Road South, say, or whichever street you have stopped in. A car park works too. - Or the nearest landmark. A car park is quicker to find by what it serves, like the one at Co-op Food. - The make and model of the vehicle, and the fact it's a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Iver, and so tell us which. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - Has it run? If so, say how far it went, and the way it was driven. - The owner may have to approve the work under some hire and company contracts — so it is quicker to settle whose car it is before our technicians arrive. Then ring 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## Waiting for a fuel drain in Iver: what to do Hold to these: well-meant help does the damage during the wait. - Where the vehicle has stopped settles where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety ahead of the vehicle. - A kind passer-by does not crank it. Nor does anybody wanting to check it still does the trick, or rolling it a few yards. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out once more. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank stays put regardless. - Not for the radio, not for the windows: your ignition remains off. ## The fuel drain, step by step, after our van gets there - Fuel, amount, whether it's run: those replies set this job, and that's why we give a price after them rather than before. - Your tank is cleared. The contaminated blend comes from the tank. - Petrol that has shifted beyond the tank sits in the lines once it ran, and the fuel lines are flushed to shift it. - Then the filter: changed where there is a usable one, cleared where there is not. - Clean diesel goes in, then the system is primed. - The first start on clean diesel. When priming is finished, your engine is started and our engineers check that it runs properly. Only once it's running on clean diesel do our technicians head off. Permanent damage is very uncommon if it has been caught quickly, so the vehicle can go straight back to normal driving. ## Back on the road in Iver after your fuel drain - Drive normally. There's nothing special to do after it's been started on clean fuel. - Pull over and call us back if anything seems 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 work may come up later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - Next time, go by the pump's label rather than the colour of its handle. ## About Iver and where it is Iver is a village in Buckinghamshire, situated on the banks of the River Colne in the South East of England.
