Motor off. Leave the vehicle that way — no second on, no moving it at all. Petrol in a diesel that has not been run is normally a simple drain plus a flush, done right where the vehicle stands, and what you do in the coming few minutes determines that more than anything else. From now on, step by step, for anywhere in Port Glasgow: ## Minute one: petrol in a diesel, engine off Before anything else, the following — following this order. - The keys out of your ignition. Switching the ignition on can be enough to prime the fuel system, while priming pulls petrol out of your tank towards the components it damages. Leave the car off altogether. - Topping up with diesel sounds like it dilutes the issue. It doesn't: nothing gets out, and that tank just holds more of the same. - Near moving traffic? Then your hazards go on before everything else, and so your car is simple to see. - Off the pump by hand. At a forecourt, get the staff to help you roll the vehicle clear of the petrol pump. Do not crank it to shift it, however short the distance. - The first thing we will ask is which fuel you put in and roughly how much — and the till receipt says both. Keep it. On the M8, under 10 miles from Port Glasgow, the next exit is the location to leave the vehicle; elsewhere, the first sensible location to stop. Don't press on to the services. Then go back to step one. ## Has it run yet? The fork in each Port Glasgow fuel drain One answer is what everything after this point depends on. If it has never been started: - Only your tank has petrol in it so far. - A drain and flush, on the spot, is usually all of that. - This, here, is the best position to be in, and the reason stage one counts. Run at all, however briefly: - Some petrol has left your tank already, passed through the filter, and reached the lines. - On a longer run it has got to the high-pressure fuel pump as well as the fuel injectors. - The job expands with the distance — lines cleaned, filter seen to, occasionally more. The reason the line falls there: diesel protects your high-pressure pump and the fuel injectors as it flows through them, and petrol does not. Nothing is damaged by petrol that's just resting in a tank. Petrol being pumped is grinding down the parts that shift it. ## Calling about petrol in a diesel from Port Glasgow: what to have prepared A van that circles against a technician that finds you: a little planning is the difference. - Your location: a postcode beginning PA14 5 serves best. - Wherever you have pulled up, the road's name helps — whether that's Church Street or somewhere else — and so does the name of a car park. - Or the nearest landmark. A car park is easier to find by what it serves, such as the one outside Tesco Extra. - Say what the vehicle is — make, model — and check it is diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Port Glasgow page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - The miles it did, and how heavily, if it has run at all. - Whose car it is. Some hire and company contracts want the owner to authorise the work, and that is quicker settled before we turn up than after. Next, 0333 366 0103. Not urgent, the vehicle parked at home with nowhere to be? Then will do too. ## Waiting for a fuel drain in Port Glasgow: what to do During the wait, the damage comes from well-meant help — which is why these count. - Where the vehicle has stopped decides where you wait. Exposed: away from it, away from the traffic. Safe: with it. Either way, safety before your car. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll it a couple of yards. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of that gets that petrol back out. - No home-made emptying. Siphoning petrol into a can by the roadside is dangerous, and it leaves the fuel that has by now gone beyond the tank. - Keep your ignition off — your windows and your radio included. ## Step by step: the fuel drain when the van arrives - Three queries. What went in, how much, and whether it's run. The replies decide this job, which is why our quote comes after them and not before. - That tank is cleared. The tainted mixture comes from your tank. - If it ran, the lines are holding petrol that has shifted beyond the tank — so they're purged. - Your filter is sorted. Cleared, or changed where your car has a serviceable one. - Fresh diesel goes in, then the system is primed. - Our technicians start the engine only after new diesel has gone in and bled the system, then make sure that it is running smoothly. The car has new diesel running through it before our technicians leave. Your car goes back to normal driving at once, and permanent damage is very rare if it has been spotted quickly. ## Back on the road around Port Glasgow after the fuel drain - Nothing special is needed after a start with clean diesel — normal driving will do. - Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - Your documents answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Port Glasgow, for a moment Port Glasgow is a coastal town in Inverclyde, situated on the southern bank of the Firth of Clyde, with nearby places including Glen Huntly and Fyfe Shore.
