Next Steps canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/bar-end-hampshire/ location: Bar End county: Hampshire latitude: 51.054670 longitude: -1.305860 service: Petrol in a Diesel Car updated: 2026-10-16 --- # The Next Steps, in Order: Petrol in a Diesel Car in Bar End Whatever you do, don't switch the engine on, even briefly, to shift the vehicle. Stop; leave it off. Drained and cleaned, just where it sits: that's usually all an unrun diesel with petrol in it needs. Whether it stays that straightforward depends on the minutes to come more than on everything else. Wherever you happen to be around Bar End, this is the order things run from now. ## Minute one: petrol in a diesel, engine off Go through the following in order, before you do anything else. - Pull the keys out. Even your ignition by itself can prime the fuel system, pulling petrol out of your tank to exactly the parts it damages, and so keep the vehicle alone wholly. - No diesel on top. More fuel in removes none of that petrol — it only leaves you with extra of the same mixture. - Visibility comes before the rest near moving traffic: put your hazards on, and only then think about everything else. - The attendants will usually help you roll it away from the petrol pump. Ask, and move it by hand — never under the engine, even for a few yards. - Hold on to the till receipt. It says which fuel was put in and roughly how much, which is the first thing we'll ask. Still on the move when you realised? Come off the M3 at the next exit if that is where you are, under a mile from Bar End, and stop somewhere safe and not pushing on to the services. Then begin at step one. ## Bar End fuel drain: has the motor run yet, or not? One answer is what everything after this stage depends on. If the engine has not run at all: - Nowhere but your tank: that's where that petrol yet is. - Where the vehicle sits is usually where this work happens: a drain, then a flush. - Step one counts for precisely this reason: it is the best spot to be in. If it has been started, even for a moment: - From your tank, past the filter, into the lines: that's how far that petrol has got. - A bigger run takes it all the way to your high-pressure pump and your injectors. - The farther it went, the bigger this job — your lines, the filter, and sometimes more besides. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it flows through, which is why the line falls where it does. Nothing is damaged by petrol that's just sitting in a tank. The components that move it are grinding the moment petrol is being pumped. ## Calling about petrol in a diesel from Bar End: what to have ready A little preparation is the difference between a van that finds you and a van that circles. - The ideal start is a postcode — one beginning SO23 9 — for where you are. - The road or the car park. A road name is a help — Barfield Close, or wherever you have pulled up. - Car parks are located most easily by what they serve: tell us the one outside Sainsbury's, and it's easy. - The make and model of your car, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Bar End page. - How long the nozzle was in, or the litres on the receipt — either gives us how much. - Has it run? If so, say how far it got, and how it was driven. - Whose vehicle it is. Some hire or company contracts want the owner to approve this work, and that's quicker settled before our technicians arrive than after. Next, 0333 366 0103. Not time-critical, your car parked at home with nowhere to be? Then works as well. ## The wait for a Bar End fuel drain, and what to do in it Help, however well meant, is the thing that does the harm while you wait. So stick to these. - Safety before your car. If it has stopped somewhere dangerous, get yourself clear of the traffic then wait away from it. If it is safe where it sits, stay with it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a couple of yards. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of that takes the petrol back out. - A DIY drain misses the fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous too. - Keep the ignition off — the windows and the radio too. ## The fuel drain, step by step, after the van gets there - Fuel, volume, whether it has run: those replies decide the job, and that is why you get a price after them instead of before. - Out of your tank comes the polluted mixture: that tank is emptied. - Petrol that has shifted beyond that tank travels in the fuel lines if it ran, and the lines are purged to clear it. - Cleared, or replaced if the vehicle has a serviceable one: your filter is sorted next. - Priming follows once fresh diesel is in. - The start-up. With new diesel in and the fuel system primed, it's started and tested to make sure it runs correctly. Your car has new diesel running through it before we go. Your car returns to normal driving straight away, and lasting damage is very rare if it has been spotted soon. ## Back on the road in Bar End after your fuel drain - After it has been started on clean fuel, there is nothing special to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop then call us a second time. - The paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About Bar End, for a moment Bar End is a suburban area situated on the riverside in Hampshire, close to the city of Winchester.
