Stop there. The next few minutes determine it more than anything else: petrol in a diesel still unrun generally amounts to clearing then flushing, on the spot. From now on, step by step, for anywhere in Gold Tops: ## Petrol in a diesel? What to do in minute one Work through the following first, in this sequence. - Keys out of the ignition. Turning your ignition on can be all it takes to prime your fuel system, while priming draws petrol out of your tank toward the parts it harms. Keep the vehicle off altogether. - Topping up with diesel seems like it dilutes the trouble. It doesn't: nothing comes out, and that tank just carries more of the same. - Close to passing traffic? Then the hazard lights come on before anything else, so the car is easy to see. - The staff will usually help you push it clear of the petrol pump. Let them, and move it by hand — never under the engine, even for a few yards. - Which fuel, and roughly how much? Your receipt answers that, and that's where our questions start. Do not throw it away. Noticed on the move? Get off at the next exit if you are on the M4, under a mile from Gold Tops, and pull over somewhere safe — not at the services further on. Step one starts after that. ## Every Gold Tops fuel drain starts here: has your motor run? From this point on, everything hinges on a single answer. If it has never been started: - All the petrol sits in your tank, and just there. - Usually it's drained and flushed right where the vehicle is. - No spot is better, and it is why the first step matters so much. Engine run, even briefly? - Some petrol has left your tank already, passed through the fuel filter, and reached your lines. - Run it further and that petrol reaches the fuel injectors, having passed through your pump first. - Mileage is what makes it a bigger job: flushed lines, a filter seen to, and at times further work. That line falls there because diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol does not. A tank of petrol, left still, damages nothing. Pump that petrol, though, and it wears the very parts doing the moving. ## Before you call about petrol in a diesel around Gold Tops: what our engineers need A little planning is the difference between a van that finds you and a van that goes round. - Your whereabouts: a postcode beginning NP20 4 works best. - A road name helps: Devon Place, say, or whichever street you've stopped in. A car park works too. - Or the landmark. A car park is quicker to find by what it serves, such as the one at Newport Food Waste Supermarket. - That it is a diesel, plus the make and model of the vehicle. - Tell us which got in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Gold Tops. - How long the nozzle was in, or the litres on your receipt — either gives us how much. - If it's run, how far plus how heavily — and if it's run at all. - Whose vehicle it is. Some hire and company agreements want the owner to authorise the work, and that's easier settled before we turn up than after. Ring 0333 366 0103 then. Writing to is fine as well if it can wait, with your car parked at home, going nowhere. ## Waiting for a fuel drain around Gold Tops: what to do Help, however well meant, is what does the harm whilst you wait. So hold to these. - Your safety comes before the car. Somewhere dangerous? Get clear of the traffic then wait away from it. Fine where it stands? Stay with it. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that gets that petrol back out. - A home-made drain misses the fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous too. - Ignition stays off. Even for the radio or your windows. ## Van arrived? Your fuel drain, one step at a time - Fuel, quantity, whether it's run: the replies decide this job, and that is why we give a quote after them rather than before. - Emptying it is how the mixture gets taken from the tank. - Petrol that has moved beyond the tank travels in your lines if it ran, and the lines are flushed to clear it. - The fuel filter is seen to. Cleared, or replaced where your car has a usable one. - Fresh diesel goes in, then the system is primed. - Our technicians fire it up only after new diesel has gone in and primed the system, then confirm that it is running properly. Only when it is running on new diesel do our engineers go. When it has been spotted early, long-term damage is very unusual, and your car goes back to normal driving at once. ## Back on the road in Gold Tops after the fuel drain - Started on fresh diesel, it needs nothing special of you. Just drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and ring us again. - The documents covers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Gold Tops Gold Tops is a suburban area located on the coast in Newport, Wales, with a mix of terraced housing and local amenities.
