Here Is What Happens Pause, and keep your motor off — not on, and not for a moment to move the vehicle. Hasn't been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever the car has stopped — and no other factor decides that more than these next few minutes do. Wherever you happen to be around Aldgate, this is how things run from here. ## Petrol in a diesel, engine off — the first minute In this sequence, and before everything else: - The ignition off, keys out. Turned on, the ignition can prime the system — and priming is what moves petrol out of your tank towards the components it harms. - No diesel on top. More fuel in takes away none of that petrol — it just makes you with extra of the same blend. - Hazard lights on. If you're anywhere close to moving traffic, make the car simple to see before you do anything else. - Off the pump by hand. On a forecourt, ask the attendants to help you push the car clear of the petrol pump. Don't fire it up to shift it, however short the distance. - Which fuel, and roughly how much? Your receipt answers both, and that's where our questions start. Do not bin it. Still driving when you noticed? Come off the M11 at the next exit if that is where you are, under 10 miles from Aldgate, and pull over somewhere sensible rather than pressing on to the services. Then begin at step one. ## Each Aldgate fuel drain starts here: has your engine run? What comes next rests on one answer, and only one. Motor never run at all? - Just your tank has petrol in it for now. - Draining and flushing, on the spot, is normally the whole job. - Being here is as good as it gets — which is the entire point of stage one. Engine run, even for a moment? - Petrol has been drawn out of the tank, past the fuel filter then into the fuel lines. - On a bigger run it has got to the high-pressure fuel pump and the fuel injectors. - The job grows with the mileage — lines cleaned, filter dealt with, sometimes more. The reason the line falls there: diesel protects your high-pressure pump and your injectors as it flows through them, and petrol does not. A tank of petrol, left alone, damages nothing. Petrol being pumped is grinding down the parts that move the vehicle. ## Calling about petrol in a diesel from Aldgate: what to have ready A technician that circles versus a technician that finds you: a little preparation is the difference. - Your location: a postcode beginning EC3M 4 works best. - The street or the car park. A road name is a help — Aldgate, or wherever you have pulled up. - Car parks are located more easily by what they serve: tell us the one outside M&S Foodhall, and it's straightforward. - The car. Make, model, plus that it's a diesel. - Say which went in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Aldgate. - How much. Litres from your receipt, or how long the nozzle was in. - The mileage it did, and how heavily, if it ran at all. - Hire or company car? Some contracts want the owner's authorisation for the work, and getting it before we get there is quicker than afterwards. Call 0333 366 0103 next. Writing to works as well if it can wait, with the car left at home, going nowhere. ## The wait for a Aldgate fuel drain, and what to do in it During the wait, the harm comes from kindly meant help — so these count. - Your safety comes before the car. Somewhere dangerous? Get away from the traffic then wait away from it. Safe where it sits? Stay with it. - No one — however helpful — starts it, whether to see if it runs or to shift your car a short way. - Something from your boot, oil meant for two-strokes or injector cleaner: no additive lifts the petrol. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank stays put all the same. - Not for your radio, not for your windows: your ignition remains off. ## When our van arrives: the fuel drain, step by step - First, three questions: which fuel went in, the volume, and has it run? Those replies decide this job, and so the price follows them. - Next the tank is drained, and the tainted fuel comes out. - Your lines are cleaned. If it ran, that petrol has moved beyond your tank, and the fuel lines are holding it. - Where the vehicle has a usable filter, it is swapped; if not, cleared. - Clean diesel in, and the fuel system primed. - Starting up. After the system is primed with clean diesel, our engineers fire it up and confirm it runs correctly. Our engineers remain until it is running on fresh diesel. Your car returns to normal use straight away, and permanent damage is very unusual if it has been noticed quickly. ## After the fuel drain: back on the road in Aldgate - Once it's been started on fresh fuel, there is nothing unusual 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 ring us once more. - Your documents answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Aldgate, briefly Aldgate is a suburban area in East London, situated near the River Thames and close to the city's financial district.
