Don't Start It Petrol in Diesel drains and cleans wrong-fuelled vehicles where they sit, on the forecourt, at the roadside or on a private drive, all over Claverton Down and the remainder of Somerset. The first thing to do is not to fire up your engine. When the engine has not run and the fuel is still sitting in that tank, a fuel drain is nearly always all it requires, and the next few minutes determine that, not how much was put in. Ring us and we shall explain what happens after that before you try anything else. ## Petrol in a diesel: what to try now - Never crank it — and do not depend on it when it does start. That is the bit people get wrong about petrol in a diesel in particular. A petrol motor filled with diesel normally just won't run, so the person stops and the harm halts with them. A diesel fed petrol normally starts, idles and pulls away perfectly well for a couple of miles. It is not okay. It is grinding the fuel system whenever you drive. - Leave the ignition alone also. Diesel performs two tasks: it burns, and before it ignites it lubricates the injection pump and its injectors. Petrol manages the first and not the second. Flicking your ignition on is frequently all it takes to prime the system, which moves this petrol out of your tank then into exactly those components. - Topping up removes nothing. It leaves you a larger tank of the same mixture, since a diesel fuel system doesn't cope with petrol by percentage as that guidance assumes — so do not add diesel on top to weaken it. Type is beside the point too: super unleaded is petrol. - We would sooner get to a difficult place than have it started — so if you sensibly can, stay still. Nothing is quicker to sort out than a motor that has not shifted. On the verge on The Avenue, that means hazards on and leave the car. - Have your location prepared before you call. A postcode beginning BA2 6 and whatever is next to you with a name on it is the difference between the van showing up and our van circling. - What got in, about how much, plus whether the car has run — these three facts decide the entire job. Phone 0333 366 0103 then tell us. ## Pump-side draining for petrol in a diesel Much of the job starts at the pump, meaning a big chunk of that is done at one. We work on station forecourts regularly, with the owner's permission, and so if you are still at Esso that is generally where the drain happens. Before your motor has fired — a forecourt is the single spot this gets halted. Anywhere else — a car park, a driveway, a lay-by — your car was started and driven to get there, which means fuel was pulled from that tank, through the fuel filter and into the high-pressure fuel pump. That is not a disaster, and we can still deal with it where it sits. It does mean the lines and your filter need flushing as well as your tank, and that is decided by the few seconds between reading your receipt and reaching for the keys. Staff will usually chip in pushing it out from the petrol pump, which lets the next customer get past. Accept the assistance. Cranking the car just for four car lengths? No. If you've put petrol in the diesel Volkswagen Passat in Claverton Down and you are now sat outside Morrisons with a boot packed with shopping, phone us. Don't crank it again to get out of the bay. We will come out to you, clear your tank, flush your fuel lines and put new diesel in so you can drive home. A mile or so at gentle throttle uses little fuel, so such jobs tend to be the easy cases. ## Areas our vans reach near Claverton Down These same runs carry us to Widcombe, Bathwick, Perrymead, Dolemeads and Lyncombe Hill besides Claverton Down, which is a residential suburb. If yours isn't on the list it does not mean we don't come — there are pages for the majority of locations across Somerset, and the ones listed above are just the nearest neighbours. Contact us and ask instead of assuming, especially if you are on the border or anywhere a satnav gets wrong. The patch the page covers sits on the map. The lot is territory our technicians cover: a kerbside, a forecourt, a private drive, a car park. You do not move your vehicle anywhere. ## Kerbside breakdowns in Claverton Down A chance to pull in somewhere sensible does not fall to everyone. Set off, then realised? Finished up along the verge of Bathwick Hill, or sat in some lay-by with the hazard lights going? That is a common call here. Not an odd one. Out of the car while it is not safe to be in it, with it when it is. Do not start it up to reach a better location. It will go — a diesel on petrol normally obliges — and each mile of obliging drags the mix deeper into the system. Driving on does your car far more harm than our van coming out to a tricky place, and that is no trouble for us. The components that should be getting oiled are wearing down instead, and the vehicle gives no sign of that: a diesel on a thinned tank starts and pulls away just fine. Chance the trip home from The Plug? Not a chance. Phone us then leave the Audi A3 where it sits. ## Driven it already? Pull in, then read this The local M4 is the one that matters here, and sits under 10 miles from Claverton Down. A drop in power, a lumpy idle, some smoke: those are the signs when they arrive, instead of a clean stop — and a misfuelled diesel will frequently take you onto it and some distance along before anything feels wrong at all. Don't restart it to reposition. Come off at the next safe exit then turn off. Long drive? Anything approaching the under 3 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that got to by the petrol. Say that on the call, as it affects what goes in our van. Fine on the way out, sluggish on the way back. If that's how the run to Smallcombe Woods went, the tank is where to look. Petrol dilutes diesel, and thinner fuel leaks past the tightly fitted components that are meant to build injection pressure — so the further your BMW 5 Series went, the less well it held that pressure. Stop somewhere sensible, switch off then ring us. ## Claverton Down itself Claverton Down is a suburban area situated on the outskirts of Bath in Somerset, with a mix of detached housing and scenic views.

Those replies change what the work actually is. - That tank gets cleared completely. - Fuel lines are rinsed through and your filter cleared, leaving nothing in the fuel system that created any of this. - We put clean diesel in and prime the system. - It's started with fresh diesel in it, and our technicians check that it is running properly. From that point, you're ready to pull away. Long-term damage is very unusual when it has been spotted early, and as all of this is done where your car is, it never has to be taken to a workshop. Leave the Vauxhall Astra close to Claverton Down Community Hall and phone us. We are direct about not driving on because a wearing pump loses, and what it loses moves on with your fuel to the injectors beyond it. ## AdBlue in your diesel tank by mistake, in Claverton Down? Never fire it up: that first instruction applies whether what was put in was AdBlue or petrol. What changes is the problem itself. Petrol dilutes the diesel and takes away the lubrication the fuel system relies on. Urea dissolved in water, AdBlue, and in a diesel tank that causes corrosion and residue. Usually the more serious of the two, AdBlue — and the detail sits on its own Claverton Down page. Both are ours to deal with. New places are where this happens most, and the reason is mechanical rather than sloppy: the slimmer petrol nozzle slides into a current diesel filler neck with practically no resistance at all. Topped up near Amphitheatre without thinking, in a diesel Ford Kuga you have had for two days? Call us where you are. Hire and courtesy cars usually get driven further before anyone notices, and mileage is what decides how much petrol reaches the fuel injectors. ## Claverton Down prices for a petrol-in-diesel fuel drain What changes the figure is laid out below, as the job isn't one job and our technicians can't frankly put a single number on this page. - Started? Driven? Either answer counts more than anything else on this list. - How much of the wrong fuel got in, measured against how much the tank holds. - Which was put in: petrol or AdBlue. - Whether our van can sensibly get to the vehicle and work on it, which hinges on where the car is. Tell us what the vehicle is, how much got in, and whether your engine has run. A straight answer comes back, not a range. For the vehicle at home that is going nowhere and isn't urgent, works too. ## Petrol in diesel: frequent questions in Claverton Down ## I'm on a forecourt around Claverton Down. Can you drain it here? Plenty of what our engineers do gets done nowhere else. So yes. Permission from the site is the condition. Given that, a forecourt like Essar is somewhere we're often enough, along with the rest of them locally — so name yours on the call and you will hear if working there is possible. ## How much petrol in a diesel is too much? Litres aren't the yardstick. Ratio is, and far more than either, it matters if anything has been run. What settles how much work is needed is whether that blend has been pulled through the fuel system — because even though five litres in an almost empty tank is a separate matter from five in a full one, either way that's the query. ## I put petrol in my diesel and drove it. Now what? Switch off somewhere safe, then keep it that way after you stop. Driving is what takes the issue from the tank into the pump and injectors — but it is fixable far more regularly than drivers expect, and the single most valuable thing you can do now isn't restart the vehicle. ## Is a fuel drain going to void my warranty? It is not an alteration, and so a drain then flush carried out properly does not cancel a manufacturer's warranty. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it switched off. ## Two-stroke oil in the tank, and then home? Two-stroke oil solves a distinct issue, and an old one at that. Nothing it does puts back what petrol diluted. No. Petrol remains in that tank after that, whatever else goes in, and the pump gets no respite from it. ## Does petrol in a diesel have to go to a main dealer? There is no need to take it to a franchised dealer, since we drain and flush the vehicle wherever it is. ## Waiting next to it? That engine stays off. Already driven it? Then pull in somewhere sensible, turn off, then let the car stay that way. This is recoverable from far more regularly than motorists assume, and a stationary, cold car is the best position to be in. Throughout Somerset and around Claverton Down: on-site fuel draining, at home or on the forecourt or at the kerbside.
