Stop there. Petrol in a diesel that hasn't been run is typically a simple drain and a flush, done right where the vehicle stands, and what you do in the next few minutes decides that far more than anything else. Wherever you are in Blyth, here is the order things go from here. ## Petrol in a diesel, motor off — the first minute Work through the following before anything else, in this sequence. - Take your keys out. Even your ignition by itself can prime the system, pulling petrol out of the tank to exactly the parts it harms, and so keep the vehicle alone wholly. - No diesel on top. More fuel in removes none of that petrol — it just makes you with extra of the same blend. - Close to moving traffic? Then your hazards go on before anything else, and so the car is easy to spot. - Off the pump by hand. On a forecourt, get the staff to help you roll the car away from the pump. Don't start it to move it, however short the way. - Hold on to your receipt: the fuel and roughly how much are printed on it, and they are what we ask for first. Still on the move when you noticed? Come off the A167(M) at the next exit if that is where you are, under 15 miles from Blyth, and pull over somewhere sensible and not pressing on to the services. Then start at step one. ## Each Blyth fuel drain starts here: has your motor run? Everything after this point depends on one answer. Not run, not even once: - That petrol is still in the tank and nowhere else. - Where your car stands is normally where this work is done: a drain, then a flush. - This is as good as it gets — which is the whole point of stage one. If it has been started, even for a second: - The lines and your filter already hold petrol drawn from that tank. - A bigger run carries it right through to your high-pressure pump and your injectors. - Flushing your lines, your filter seen to, occasionally more: the job grows as the miles does. Diesel keeps the high-pressure fuel pump and the injectors lubricated as it goes through them. Petrol offers them nothing, and that's why the line is drawn there. Nothing is damaged by petrol that's just resting in a tank. The components that move it are wearing the moment petrol is being pumped. ## Before you call about petrol in a diesel in Blyth: what our engineers need Prepare a little, and the van finds you rather than circling. - Where you have stopped. A postcode beginning NE24 1 is the ideal place to start. - A road name helps: Bridge Street, say, or whatever street you've stopped in. A car park does the trick too. - What a car park serves is the easiest way to find it, and so mention the landmark — like the one outside Heron Foods. - Say what the car is — make, model — and confirm it's diesel. - Tell us which got in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Blyth. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - The mileage it did, and how hard, if it has run at all. - Whose car it is. Some hire and company agreements want the owner to authorise the work, and that's quicker settled before our engineers get there than after. Next, 0333 366 0103. Not urgent, the car left at home with nowhere to be? Then will do as well. ## Whilst you wait for a fuel drain around Blyth The wait is where well-meant help does the harm. Stick to these. - Where the vehicle has stopped settles where you wait. Exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before the vehicle. - 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. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive removes the petrol. - No DIY emptying. Siphoning petrol into a can at the roadside is risky, and it leaves the fuel that has by now gone beyond the tank. - Even your radio or your windows aren't worth switching the ignition on for. ## When the van arrives: your fuel drain, step by step - Fuel, quantity, whether it has run: those answers decide this job, and that's why you get a quote after them instead of before. - Then the tank is drained, so the polluted fuel comes out. - If it ran, the lines are carrying petrol that has shifted beyond your tank — so they're cleaned. - Cleared, or swapped if the vehicle has a serviceable one: the fuel filter is sorted next. - Bleeding the system follows after fresh diesel is in. - We start the car only after new diesel has gone in and bled the fuel system, then check that it's running correctly. Until it runs on new diesel, we stay with it. Long-term damage is very rare if it has been spotted soon, so your car can go right back to normal use. ## After the fuel drain: back on the road in Blyth - Drive normally. There is nothing unusual to do once it's been started on clean fuel. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your signal to stop then call us once more. - Keep your documents. A hire firm, a fleet manager or an insurer may ask what was carried out. - Next time, trust the pump's label instead of the colour of its handle. ## About Blyth Blyth is a coastal town in Northumberland, situated on the north east coast of England, with a population of around 16881 people.
