Pause; leave the car off. The next few minutes settle it more than anything else: petrol in a diesel that has not run generally comes down to draining and rinsing, on the spot. Anywhere you are in Great Glen, here is how things go from here. ## Engine off: minute one with petrol in a diesel Do the following before anything else, in this order. - Bleeding your fuel system draws petrol from the tank towards the parts it damages, and turning your ignition on can be enough to do that. So your keys get taken out, and the ignition stays off altogether. - No diesel on top. More fuel in takes away none of the petrol — it only leaves you with extra of the same blend. - Visibility comes before the rest near moving traffic: put your hazards on, and only then think about anything else. - The staff will generally help you roll it away from the petrol pump. Let them, then move it by hand — never on the engine, even for a few yards. - The first question we will ask is which fuel you put in and about how much — and the till receipt shows both. Keep it. If you were still driving when you noticed, stop somewhere safe instead of pushing on for the services — on the M1, under 10 miles from Great Glen, that means the next junction. Step one comes next. ## Every Great Glen fuel drain starts here: has the motor run? What comes after this rests on one answer, and only one. Not run, not even briefly: - All the petrol sits in that tank, and only there. - Where the vehicle sits is normally where this work is done: a drain, then a flush. - This is the best spot to be in, and the reason step one matters. Run at all, even for a second: - Some petrol has left your tank by now, gone through the fuel filter, and got into your lines. - A longer run carries it all the way to the high-pressure fuel pump and the fuel injectors. - Miles is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work. Petrol does not lubricate. Diesel does, protecting the pump and injectors as it passes through, which is why the line falls where it does. Nothing is damaged by petrol that is just sitting in a tank. Petrol being pumped is wearing the parts that move the vehicle. ## What to have ready when you call about petrol in a diesel from Great Glen Whether the van goes round or finds you depends on a little preparation. - Where you have stopped. A postcode beginning LE8 9 is the best start. - A road name is a help: Main Street, say, or whichever street you've stopped in. A car park does the trick too. - Or the nearest landmark. A car park is easier to find by what it serves, like the one at The Co-operative Food. - The car. Make, model, and that it's a diesel. - Which was put in matters: AdBlue is a separate job from petrol, and Great Glen has a page for it. So say. - How long the nozzle was in, or the litres from the receipt — whichever gives us how much. - Whether it has run. Then if it has, how far and how hard. - The owner may have to approve this work under some hire or company contracts — so it's faster to settle whose motor it is before we get there. Phone 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use . ## While you wait for a fuel drain in Great Glen The wait is where well-meant help does the harm. Hold to these. - Where the vehicle has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the car. - A helpful passer-by does not fire it up. Nor does anyone checking it still does the trick, or rolling it a couple of yards. - Additives stay in your boot. Injector cleaner and two-stroke oil take none of the petrol out again. - A DIY drain misses the fuel already gone beyond that tank, and siphoning petrol by the road is hazardous besides. - Leave the ignition off — the windows and the radio too. ## The fuel drain, step by step, after our van gets there - First, three queries: which fuel was put in, the quantity, and has it run? Those answers decide the job, and so the quote follows them. - Out of your tank comes the contaminated blend: that tank is cleared. - Petrol that has moved beyond your tank travels in the fuel lines if it ran, and your lines are purged to shift it. - Cleared, or changed if the vehicle has a usable one: your filter is sorted next. - Clean diesel goes in, then the system is primed. - Starting the car. Once the system is primed with clean diesel, we start the engine and make sure it runs correctly. Our engineers stay until it's running on clean diesel. It is very unusual for a car spotted soon to be left with long-term damage, and normal driving resumes straight away. ## Back on the road around Great Glen after the fuel drain - Started on clean diesel, it needs nothing unusual of you. Just drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over and call us back. - The work may come up later with a hire firm, an insurer or a fleet manager. Keep your paperwork. - Check the label on the petrol pump next time, not the colour of the handle. ## About Great Glen and where it is Great Glen is a village in Leicestershire, situated on the banks of the River Sence, with a mix of old and new housing, predominantly detached homes.
