Petrol in a Diesel Car in Hallowsgate Less than you likely are, if it hasn't been started. Everyone in Hallowsgate starts with "have I ruined it?", and the fair answer is normally no: petrol resting inside your tank of any diesel stays harmless until priming, cranking or driving draws it into your fuel system. Keep it like that: leave the engine off then phone Petrol in Diesel. What petrol really does to a diesel, how to judge how far it's travelled, and how to keep it from happening again: that is the rest of this page. ## Inside your engine: what petrol in a diesel really does Passing through an engine, diesel does two jobs at once. It protects to begin with, and only then does it burn. Made to very fine tolerances, your injectors and the pump rely on your diesel flowing through them to keep their surfaces from wearing against one another. Petrol handles the first job poorly and the second not at all. A pump working on a petrol mix is wearing itself out, since petrol is thinner than diesel and strips out the protection the fuel system depends on. Petrol is also made to resist igniting under compression — the reverse of what a diesel wants from its fuel — and that's where any rattling comes. Put those together and the shape of the problem is clear. Contact does not do the harm — circulation does. All a tank with petrol in it amounts to is a fuel fault. A pump that has been working on that petrol is the start of a mechanical one, and whatever a worn pump sheds moves on with your fuel to the injectors downstream. ## Hallowsgate, petrol in a diesel: four cases, from mild to major Fuelled, and never started: no case is better. Being at a forecourt is what makes this possible: elsewhere, the vehicle has been driven there to begin with. With the petrol kept in the tank alone, it is emptied and rinsed on the spot, and nothing more is needed. Ignition on, or started for a moment. The system has been bled, and so petrol has left your tank and got to your filter and your lines. Still normally straightforward: drain, flush, and the filter dealt with. Your pump has spent a few miles on thinned fuel — that's what driving the vehicle meant. Miles is only half of it; how hard it was driven counts equally. Either way this work runs to that tank, your lines, your filter and clean fuel through the whole system. Short trips, such as the school run to Kelsall Primary and Nursery School, are one thing. Getting as far as Chester, under 10 miles away, makes a very different job — as does any distance on the M53, under 10 miles from Hallowsgate, with your engine labouring hard all the way. It protested, and only then stopped: smoke, rattling, a throttle gone soft, an idle gone lumpy. That's the engine telling you its fuel has stopped behaving like diesel. Leave it where it stops: a lay-by, a quiet street, the verge on The Wynd. The fuel drain and flush still come first, and they deal with it: when a car is pulled over early, long-term damage is very rare. ## Myths Hallowsgate motorists hear about petrol in a diesel It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be." Nothing is removed when you top up — your tank just holds more of the same blend. A diesel fuel system doesn't accept petrol by percentage in the way that guidance assumes. Not so: a modern diesel copes with a bit of petrol. If anything, the opposite. More precise parts and higher pressure are how a newer diesel runs its fuel, and that makes the protection count more, not less. Myth: "If it starts and drives, there is no damage done." This is the one that fools motorists. Diesel in a petrol motor generally leaves a motor that won't run: the driver stops, and so does the harm. Nothing looks to have happened when a diesel fed petrol fires up, ticks over and drives away, which it usually does; meanwhile the pump grinds. Being able to run is not proof of being fine. An old fix for a distinct problem is behind this one. Myth: "Add some two-stroke oil and drive it home." None of what petrol weakened is put back by it — and afterwards, your tank still contains the petrol. "Drain it yourself and you are sorted" — a myth, because after it has been running some petrol sits in the fuel filter and lines, waiting to go right back through the pump at the next start. It's also truly hazardous to drain petrol into a can at the roadside. ## Petrol in a diesel: how does it happen? No one does it on purpose, and it is rarely carelessness. The forecourt makes it simple: the petrol nozzle is the smaller of the two, and it slips into a diesel filler with almost no resistance, whilst a diesel nozzle mostly won't go into a petrol car at all. So the error runs one way. It occurs when routine and the vehicle stop matching. A motor that is new to you — a hire car, on loan as a courtesy car, or just bought. One petrol and one diesel on the drive of the same household. A forecourt you know, but with its pumps laid out differently. A hurried fill on the way to Mouldsworth with a train to catch. The first fill-up in a diesel Volkswagen Passat after years of driving petrol is precisely the moment it takes place. Throw in rain, a phone call or a back seat full of children, and the hand repeats what it has always done. ## How to avoid petrol in a diesel on your next fill-up around Hallowsgate - The label is what matters, and so check the petrol pump instead of the colour: in the UK unleaded handles are normally green and diesel black, yet not on each forecourt. - Check your filler flap. Many cars state the fuel type inside the flap or on the cap. Look at it on the first fill in any motor you do not know. - Label your key. In a home with one of each, a coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember. - Say it before you lift it. On the first fill in a new or hired car, say "diesel" out loud before you lift the nozzle off the pump. It seems daft and it works. - Put the phone away. This is an easy mistake to make whilst you're thinking about something else. - Some diesels have a filler built to block a petrol nozzle, and devices you can add are available for motors without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop reading the petrol pump. - Less petrol means a weaker blend, so stop the moment you realise — though remembering that your next stage is unchanged. It is still not to crank it. ## Already put petrol in a diesel in Hallowsgate? Short and simple, then, is the order of things. Don't crank it, and do not turn the ignition on. The attendants at the forecourt — whether at BP itself or wherever you filled up — will normally help push it clear of the pump if you ask. Then ring 0333 366 0103 and tell us what went in, roughly how much, and if it's run. AdBlue, not petrol? Then say so. Corrosion and deposits, not lost lubrication, make it a separate problem — Hallowsgate has a page all for it. ## What makes one Hallowsgate petrol in a diesel job cost more than the next There's no fair single quote for this, because the four situations above are four separate tasks. What shifts the cost is mostly which of them you are in. Next it is the proportion — how much petrol got in against how much that tank holds — and then where the vehicle is and whether a technician can get to it safely. Before any quote, not after, come three questions: your fuel that got in, the volume, and whether it has run. That's why. The replies turn a range into a straight figure. ## About Hallowsgate, for a moment Hallowsgate is a locality in Cheshire, situated inland at an elevation of 68 metres, approximately 7.5 miles from Chester.
