Petrol in a diesel that hasn't been run is generally a drain and a flush, done right where the vehicle sits, and what happens in the coming few minutes decides that far more than anything else. Anywhere you happen to be around Stirling, this is how things run from here. ## Engine off: minute one with petrol in a diesel In this sequence, and before everything else: - Priming your fuel system pulls petrol from your tank toward the components it harms, and turning the ignition on can be all it takes to do that. So your keys come out, and the ignition remains off altogether. - Topping up with diesel sounds like it thins the trouble. It doesn't: nothing gets out, and that tank just carries more of the same. - Hazards on. If you are anywhere close to moving traffic, make the vehicle simple to see before you do anything else. - However short the distance, starting it to shift it is the thing to avoid. On a forecourt, roll the vehicle clear of the petrol pump by hand instead, then ask the attendants to lend a hand. - The first question we will ask is which fuel went in and roughly how much — and the till receipt shows both. Hold on to it. On the M9, under 3 miles from Stirling, the next junction is the location to leave it; anywhere, the first sensible spot to stop. Do not press on to the services. Then go back to stage one. ## Stirling fuel drain: has the engine run yet, or not? One answer is what everything after this stage depends on. Not run, not even briefly: - Just that tank has petrol in it for now. - The job is a simple drain and a flush, normally done where your car is. - This is the best spot to be in, and the reason stage one counts. Run at all, even for a second: - Some petrol has left your tank already, gone through the fuel filter, and got into the fuel lines. - The high-pressure pump and the fuel injectors see it too on a bigger run. - The farther it went, the larger this job — the fuel lines, the filter, and sometimes more besides. Petrol doesn't lubricate. Diesel does, protecting your pump and injectors as it flows through, which is why the line falls where it does. In your tank, sitting still, petrol does no harm. Once it's pumped, petrol begins wearing down whatever moves it. ## What to have prepared when you call about petrol in a diesel from Stirling A technician that circles against a van that finds you: a little planning is what separates them. - Your location: a postcode starting FK8 2 serves best. - The street or the car park. A road name is a help — Wellgreen Road, or wherever you have pulled up. - Describe a car park by what it serves — the one at M&S Foodhall, for example — and it is much quicker to find. - The vehicle. Make, model, and that it's a diesel. - Which went in matters: AdBlue is a separate job from petrol, plus Stirling has a page for it. So tell us. - How long the nozzle was in, or the litres from the receipt — either gives us how much. - Whether it has run. And if it has, how far and how heavily. - Settle who owns the car before our technicians arrive: some hire and company contracts want the owner to approve the work, and that is faster first. Next, 0333 366 0103. Not pressing, the car parked at home with nowhere to be? Then will do as well. ## Waiting for a fuel drain around Stirling: what to do The wait is where kindly meant help does the damage. Hold to these. - Safety before the car. If it has stopped somewhere exposed, get yourself clear of the traffic and wait away from it. If it's safe where it is, wait with it. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll it a couple of yards. - Additives remain in your boot. Injector cleaner and two-stroke oil take none of the petrol out a second time. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank remains where it is all the same. - Even the radio or the windows aren't worth switching the ignition on for. ## The fuel drain, step by step, after the van gets there - Three questions. What got in, how much, and if it has run. The replies set the job, which is why our price comes after them but not before. - Then the tank is drained, and the polluted fuel comes out. - If it ran, your lines are holding petrol that has moved beyond that tank — so they are flushed. - Where your car has a workable filter, it's changed; otherwise, cleared. - Priming comes after fresh diesel is in. - Starting it. When the fuel system is primed with clean diesel, our engineers fire it up and make sure it runs correctly. The car has fresh diesel running through it before our technicians go. Long-term damage is very uncommon when it has been spotted early, so your car can go straight back to normal driving. ## After your fuel drain: back on the road in Stirling - Started on fresh diesel, it asks nothing special of you. Just drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over then call us back. - An insurer, a fleet manager or a hire firm may ask what was done, so keep the paperwork. - Next time, trust the pump's label rather than the colour of its handle. ## About Stirling, for a moment Stirling is a city situated in central Scotland, nestled between Glasgow and Edinburgh, and is characterised by its riverside location on the River Forth.
