Petrol in a Diesel Car in Bolehall Far less than you likely are, if it hasn't been started. Everyone in Bolehall begins with "have I wrecked it?", and the fair answer is generally no: petrol resting in that tank of a diesel stays harmless until priming, cranking or driving draws it into the system. Keep it like that: leave your engine off then call Petrol in Diesel. The remainder of this page sets out what petrol actually does to a diesel, how to tell how far it has got, and how to make sure it does not happen to you again. ## Petrol in a diesel: what does it do to your engine? Passing through an engine, diesel does two jobs at the same time. Before it ignites, it lubricates — and then it combusts. Very fine tolerances are built into your injectors and the high-pressure fuel pump, and just your diesel running through stops their surfaces grinding together. Petrol handles the first task poorly and the second not at all. Being less viscous than diesel, petrol strips out the lubrication a fuel system needs, so a pump on the mixture to wear itself. It's equally made to resist igniting under compression — the opposite of what a diesel needs — which is where you get the knocking. Taken together, they make clear the shape the problem takes. Not contact but movement is what causes the damage. Any tank with petrol in it is a fuel fault. The start of a mechanical one is a pump that has been working on that petrol — and whatever a worn pump sheds moves on with your fuel to the injectors beyond it. ## Bolehall, petrol in a diesel: four situations, from mild to serious The best case there can be: filled up, never started. The petrol is inside your tank and only your tank, and the job is a drain and a flush where your car sits. This is the one situation that can only truly occur on a forecourt, as anywhere else the car has been driven to get there. A moment's running, or merely the ignition on. Petrol has come out of your tank and reached the fuel filter and the fuel lines, because your system has been bled. Usually nothing more than emptying, rinsing and seeing to the fuel filter, so still simple. Driven a few miles. Now your pump has spent those miles working on thinned fuel. Tank, lines, filter, then fresh fuel put through the whole system: that is the work, and the way the vehicle was driven counts as much as the mileage. On the school run to Ankermoor Primary Academy, the distance is small. A run as far as Lichfield, under 10 miles away, is a very different job. So is any distance on the M42, under 3 miles from Bolehall, where the motor has been labouring hard the whole time. Rattling, a ragged idle, smoke, a throttle gone soft: driven until it complained. That's your motor telling you its fuel has stopped acting like diesel. Leave it wherever it has stopped: a lay-by, a quiet street, the verge on Goostry Close. A vehicle stopped soon very rarely has permanent damage, as the drain and the flush-through, which still come first, take care of it. ## Petrol in a diesel stories Bolehall motorists hear False: topping up to full with diesel makes it fine. It does not. Nothing comes out when you top up — the tank just carries more of the same blend. Percentage is not how a diesel fuel system copes with petrol, however much that advice assumes. Myth: "A newer diesel can cope with a bit of petrol." If anything, the reverse. At higher pressure, through smaller components: that is how a newer diesel handles its fuel, so the lubrication counts for more, not less. One myth that catches people out: if it starts and drives, it must be unharmed. Feed diesel to a petrol engine and it generally will not run, so the motorist stops — and the harm stops with them. Feed petrol to a diesel and it generally fires up, idles and drives away like nothing has happened — all while its pump wears. Fine and running are not the same thing. An old workaround for a different issue is behind this one. Myth: "Add some two-stroke oil and drive the car home." It does not put back what petrol has thinned, and the petrol is still in that tank afterwards. Myth: "Drain the tank yourself and you're sorted." After the motor has run, some of that petrol is no longer in that tank: it is in the fuel filter and your lines, and it goes right back through your pump on your next start. Draining petrol into a can at the roadside is also truly hazardous. ## Why petrol in a diesel happens so easily Nobody does it on purpose, and it is seldom carelessness. The forecourt makes it easy: the petrol nozzle is the smaller of the two, and it slips into a diesel filler with almost no resistance, while a diesel nozzle generally won't go into a petrol car at all. So the slip runs one way. Habit and your car falling out of step is how it occurs. Hire cars, courtesy cars, and motors that are new to you. Households running one of each, petrol and diesel. Your usual forecourt, its pumps now in a different order. Fuelling up in a rush en route to Tamworth, with a train to catch. A new-to-you diesel Renault Clio, its first fuelling, and a motorist used to petrol: precisely when it occurs. Add a back seat full of kids, a phone call or rain, and the hand wins. ## Bolehall motorists: how to prevent petrol in a diesel next time - The label is what matters, and so check the petrol pump rather than the colour: in the UK unleaded handles are usually green and diesel black, but not on each forecourt. - In a motor you do not know, look inside the flap over your filler or at the cap before the first fill: plenty of motors state the fuel type there. - Good intentions do less than a sticker or a fob in a vivid colour on the diesel's key if a household has one of each. So label it. - Say it before you lift it. On the first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the pump. It seems daft and it works. - Thinking about something else is when this becomes an easy mistake to make, and so tuck your phone away then keep your mind on the pump. - Add-on devices are available for vehicles without one, and some diesels are built with a filler that will not accept a petrol nozzle. Helpful — but a safety net only, never a reason to stop checking the label. - As soon as you realise, stop: less petrol in your tank makes a thinner blend. What to do next does not change, though — still do not crank it. ## Already put petrol in a diesel around Bolehall? In that case, there's just a short order of things. Starting it is out, and so is switching on your ignition. The staff on the forecourt — whether at Texaco itself or wherever you filled up — will usually help push it away from the petrol pump if you ask. Next, 0333 366 0103. We will ask what got in, about how much, and if it's been run. Say so if it was AdBlue rather than petrol: it's a separate problem, with its own page for Bolehall, because AdBlue brings corrosion and deposits instead of lost protection. ## What makes one Bolehall petrol in a diesel job cost more than the next There is no fair single price for this, since the four situations above are four different jobs. Chiefly, your cost moves with which one you're in. Where the car is matters too, and whether our van can safely reach it, after the share of petrol to what your tank takes. What got in, how much, and whether it's run — three questions our technicians ask before quoting, not after, for exactly that reason. Given those replies, you get a straight figure instead of a range. ## About Bolehall itself Bolehall is a suburban area in Staffordshire, situated on the riverside at an elevation of 77 metres, with semi-detached housing being the predominant type of accommodation.
