Next Steps canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/markfield-leicestershire/ location: Markfield county: Leicestershire latitude: 52.686730 longitude: -1.277940 service: Petrol in a Diesel Car updated: 2026-10-16 --- # The Next Steps, in Order: Petrol in a Diesel Car in Markfield Not for a moment, and not for moving it: the engine remains off. Stop there. The next few minutes decide it far more than anything else: petrol in a diesel that has not run generally comes down to emptying then cleaning, on the spot. Here's the sequence of things from now, anywhere you are in Markfield. ## Motor off: minute one with petrol in a diesel In this sequence, and before anything else: - Keys out of your ignition. Switching the ignition on can be enough to prime your fuel system, and priming draws petrol out of the tank towards the components it harms. Leave the vehicle off altogether. - Do not top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mix. - Hazards on. If you're at all near moving traffic, make the car easy to see before you do anything else. - Off the pump by hand. On a forecourt, get the attendants to help you push it clear of the petrol pump. Don't start the vehicle to move it, however short the distance. - The first thing we will ask is which fuel went in and about how much — and the till receipt says both. Hold on to it. If you were still on the move when you noticed, stop somewhere sensible rather than pushing on for the services — on the M1, under a mile from Markfield, that means the next junction. Stage one follows. ## The fork in each Markfield fuel drain: has it run yet? Everything after this stage depends on one answer. If it has never been started: - Only the tank has petrol in it so far. - Where the vehicle stands is normally where the work is done: a drain, then a flush. - Step one counts for precisely this reason: it is the best position to be in. If your engine has run, even briefly: - Petrol has been pulled from your tank, through the fuel filter then into your lines. - On a longer run it has reached your high-pressure pump and the injectors. - Flushing your lines, your filter seen to, occasionally more: this job grows as the distance does. The reason the line falls there: diesel protects your high-pressure pump as well as the fuel injectors as it passes through them, and petrol does not. Petrol sitting in a tank harms nothing. As soon as it is pumped, petrol starts wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Markfield A technician that circles versus a technician that finds you: a little preparation is what separates them. - The ideal start is a postcode — one beginning LE67 9 — for where you are. - Give the road — Upland Drive or wherever you have stopped — or the car park. - Name a car park by what it serves — the one at The Co-operative Food, for instance — and it is much easier to find. - Tell us what the vehicle is — make, model — and check it's diesel. - Say which got in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Markfield. - The quantity: your receipt's litres, or otherwise how long you held the nozzle in. - The miles it did, and how heavily, if it ran at all. - The owner may have to approve this work under some hire and company contracts — which is why it is faster to settle whose car it is before our engineers arrive. Call 0333 366 0103 then. Writing to works too if it can wait, with the car parked at home, going nowhere. ## Whilst you wait for a fuel drain in Markfield Help, however well meant, is what does the damage whilst you wait. So stick to these. - Your safety comes before the vehicle. Somewhere dangerous? Get away from the traffic and wait away from it. Safe where it is? Wait with it. - No one — however helpful — starts it, whether to see if it runs or to shift your car a short way. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that gets the petrol back out. - No home-made emptying. Siphoning petrol into a can by the kerbside is risky, and it leaves the fuel that has already gone beyond the tank. - The ignition stays off. Even for the radio or the windows. ## When our van arrives: your fuel drain, step by step - The price comes after three questions, not before them — what went in, how much, and whether it's run — since the answers set the job. - That tank is emptied. The tainted blend comes out of your tank. - The lines are rinsed. If it ran, the petrol has shifted beyond your tank, and the lines are carrying it. - Where your car has a serviceable filter, it's swapped; if not, cleared. - Clean diesel in, and your system primed. - We fire it up only after new diesel has gone in and bled the system, then make sure that it's running correctly. Only when it is running on fresh diesel do our engineers leave. Long-term damage is very unusual when it has been caught quickly, so the vehicle can go right back to normal use. ## Back on the road in Markfield after the fuel drain - Drive normally. There's nothing special to do after it's been started on clean fuel. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle tells you to pull over then call us back. - Keep the documents. A hire company, a fleet manager or an insurer may ask what was done. - The handle's colour is not the guide to go by next time — the label on the pump is. ## About Markfield itself Markfield is a village in Leicestershire, situated approximately 7 miles northwest of Leicester, and is characterized by its semi-detached housing stock.
