Here Is What Happens Not for a moment, and not to move it: your motor stays off. Stop there. Emptied and purged, right where it sits: that's normally all an unrun diesel with petrol in it takes. Whether it stays that simple depends on the minutes ahead more than on anything else. Here is the order of things from now, anywhere you are in Deritend. ## Minute one: petrol in a diesel, motor off In this sequence, all before everything else: - Bleeding the fuel system draws petrol from the tank toward the parts it damages, and switching the 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 makes you with extra of the same blend. - Close to passing traffic? Then the hazards come on before anything else, so your car is simple to see. - However short the distance, starting it to move it is the thing to avoid. At a forecourt, push the car away from the petrol pump by hand instead, and ask the staff to lend a hand. - Hold on to the receipt. It shows which fuel was put in plus about how much, which is the first thing we will ask. If you were still driving when you realised, pull over somewhere safe rather than pushing on for the services — on the Aston Expressway, under 3 miles from Deritend, that means the next junction. Stage one comes next. ## Every Deritend fuel drain starts here: has the motor run? One answer is what everything after this point rests on. Motor not run at all? - Nowhere but the tank: that's where that petrol still is. - A drain and flush, on the spot, is usually the whole job. - Being here is the best case — which is the entire point of step one. Run at all, even for a second: - From the tank, through the fuel filter, into your lines: that is how far that petrol has travelled. - A longer run carries it all the way to your high-pressure pump and the fuel injectors. - The job grows with the distance — lines cleaned, filter dealt with, occasionally more. Why the line falls there: diesel protects the high-pressure pump as well as the fuel injectors as it flows through them, and petrol doesn't. A tank of petrol, left still, hurts nothing. The components that move it are grinding the moment petrol is being pumped. ## What to have prepared when you call about petrol in a diesel from Deritend A van that circles versus a van that finds you: a little preparation is the difference. - The best start is a postcode — one starting B12 0 — for where you have stopped. - A road name helps: Warwick Street, say, or whichever street you have stopped in. A car park does the trick too. - Car parks are located more easily by what they serve: say the one outside Spar, and it's easy. - That it is a diesel, plus the make and model of your vehicle. - Say which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Deritend. - The quantity: the receipt's litres, or else how long you held the nozzle in. - Whether it's run. Then if it has, how far plus how heavily. - Whose motor it is. Some hire or company contracts want the owner to approve the work, and that is quicker settled before our technicians arrive than after. Call 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use . ## Deritend fuel drain on its way? While you wait Hold to these: well-intended help does the harm during the wait. - Where the car has stopped decides where you wait. Exposed: away from it, away from the traffic. Sensible: with it. Either way, safety ahead of the vehicle. - Nobody — however helpful — starts it, whether to see if it runs or to shift the car a short way. - Additives remain in your boot. Injector cleaner and two-stroke oil take none of that petrol out a second time. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank remains put all the same. - Not for your radio, not for the windows: the ignition remains off. ## When the van arrives: the fuel drain, step by step - Fuel, amount, whether it's run: those answers decide this job, and that is why we give a price after them rather than before. - Out of that tank comes the tainted blend: that tank is cleared. - Purging the fuel lines follows, since a vehicle that ran has petrol past that tank, inside the fuel lines themselves. - Your filter is seen to. Cleared, or swapped where the vehicle has a workable one. - Clean diesel goes in, then the fuel system is primed. - Starting the car. After your system is bled with fresh diesel, our technicians fire it up and confirm it runs properly. Only when it's running on fresh diesel do our technicians leave. If it has been spotted early, long-term damage is very rare, and your car returns to normal use straight away. ## After the fuel drain is done: driving in Deritend once more - Started on new diesel, it needs nothing unusual of you. Simply drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and ring us again. - An insurer, a fleet manager or a hire firm may ask what was done, and so keep the paperwork. - Check the label on the petrol pump next time, not the colour of its handle. ## About Deritend itself Deritend is a suburban area in the West Midlands, situated on the riverside near the city of Birmingham.
