--- title: Petrol in a Diesel Car Tricketts Cross — Fuel Drain canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/tricketts-cross-dorset/ location: Tricketts Cross county: Dorset latitude: 50.807700 longitude: -1.874180 service: Petrol in a Diesel Car updated: 2026-10-21 --- # Put Petrol in a Diesel Car in Tricketts Cross? Don't Start It With the tank still holding the petrol and the motor not yet turned over, nearly every job requires only a drain, so leave your engine off. That result is determined in the minutes straight after filling up, and not by the amount that was put in. Across Tricketts Cross and the rest of Dorset, Petrol in Diesel drains the car and cleans it where it stands, whether by a roadside, on a private drive or at a forecourt. One ring to us is plenty: our technicians can tell you what comes next. Try it right away. ## The next five steps: petrol in a diesel - Don't start it — and do not depend on it if it starts. Here is the thing motorists get wrong about petrol in a diesel specifically. A petrol motor filled with diesel normally just cannot run, so the person stops and the wear stops with them. A diesel filled with petrol normally starts, ticks over and drives away without complaint for a couple of miles. It's not fine. It's grinding that fuel system whenever you drive. - Two things, diesel: it ignites, and on the way through it keeps your injection pump and injectors greased. Petrol only handles the one. That is why the car's ignition is left off too — flick it on and you usually prime the system, and that is petrol leaving the tank for precisely those parts. - That guidance assumes a diesel fuel system tolerates petrol by percentage. It will not. Tip diesel on top and nothing at all is taken out; what you get is a bigger tank of the same blend. And no, the grade makes no difference — super unleaded is just petrol. - Remain where you are if you sensibly can. A vehicle that has not moved is the quickest one to sort out, and we'd sooner drive to an odd place than have it started. If you're parked on the verge on Lockyers Drive, switch your hazards on then leave the car there. - Check where you are before phoning. A postcode starting BH22 8, and the name of whatever is nearest to you. Otherwise the technician circles rather than arriving. - What was put in, roughly how much, and if your car has started — those three replies settle the entire job. Dial 0333 366 0103 and tell us. ## Clearing petrol from your diesel at a forecourt Much of this work starts at a forecourt, which means a fair portion of it ends up completed there. Still at Sainsbury's? Then that's usually where it takes place. Station forecourts are everyday for us, with the permission of the station. A forecourt is the single spot the mistake gets stopped before the motor has fired. Everywhere else — a car park, a private drive, a lay-by — the car was fired up and moved to get there, which means fuel was pulled from the tank, through the filter then into your high-pressure pump. That's not a disaster, and our technicians can still deal with it where it stands. It does mean the fuel lines and the fuel filter need flushing as well as your tank, and that's settled by the few seconds between seeing your receipt and going for the keys. Staff will usually help out pushing it out from the pump, which lets the next customer get through. Welcome the help. Rolling the car four lengths does not warrant starting the motor. Tell us this much and our technicians can work with it: a diesel Skoda Octavia, a couple of litres of unleaded in it, two miles or so, turned off outside Sainsbury's now. Time passed is not the thing our engineers need. Fuel drawn by the pump is. ## Tricketts Cross plus the areas next to it St Leonards Farm Park, Ferndown, West Moors, Ameysford, Dudsbury — each of them on our journeys that carry us out to Tricketts Cross too, a village. Not on the list? It says nothing. The names above are simply the closest few, and nearly all towns around Dorset have a page of their own somewhere on our site. Presuming is the mistake to skip, particularly on the boundary or anywhere your satnav gets lost. Contact us and check. Look at our map for the patch shown on this page. We operate roadside, on forecourts, on driveways and in car parks across all of it, and your vehicle doesn't need to move to us. You'll be advised to move it clear of the gateway and sort it out later. Don't. On the zig-zags outside Oakhurst Community First School, a wrongly fuelled Nissan Qashqai running on diesel is in the way, and that's all it is. Fire it up three more times being courteous and you have turned a tank into a fuel system: every start primes your lines, every prime drags more petrol past your filter on to the pump. Let them complain. Phone us. ## Kerbside call-outs across Tricketts Cross Some people get no suitable spot to stop whatsoever. If you realised after setting off and landed by the verge of Turbary Road, or in a lay-by somewhere with your hazards flashing, that's a common call for us and not an unusual one. Safe there? Stay with it. Not safe? Move out and away from it. Every mile a diesel obliges you for on petrol draws that blend further into the system — and oblige it usually will, which is why your motor doesn't get restarted to limp somewhere better. Pressing on does the vehicle far more harm than a technician heading out to an inconvenient spot, and that's no trouble for us. Try the drive home from The White Heather? Not a chance. It will fire up and it will move off quite happily, which is the trouble — a diesel on a weakened tank runs normally while wearing down the parts your fuel should be protecting. Leave the Mercedes C-Class and call us. ## So you've run it? Petrol in a diesel after some miles Your M27 is the road that matters here, and it runs under 15 miles from Tricketts Cross. A drop in power, an uneven idle, smoke: those are the symptoms when they appear, instead of a tidy stop — and a wrongly fuelled diesel will frequently take you onto it and some way along before anything seems wrong at all. The first sensible exit is the one to take. Turn off there, and leave the restarting alone. On a longer drive — anything close to the under 25 miles to the nearest city — take it the petrol has been through your filter, your pump and the fuel injectors, and tell us when you ring. It affects what we bring. ## All about Tricketts Cross Tricketts Cross is a village in Dorset, situated near the River Stour and surrounded by countryside. Tricketts Cross has a mix of housing types, but terraced houses are particularly prevalent. Tricketts Cross is located near several other settlements, including Ferndown and West Moors, and is close to St Leonards Farm Park. Tricketts Cross is approximately 18.5 miles from Salisbury and 89.8 miles from London. ## Once we get to you in Tricketts Cross: what happens - Three things get checked before any price — the fuel that was put in, the amount, and whether anything has been run since. Each answer alters the work. - Away goes the polluted fuel. - Lines flushed, filter cleared. Whatever remains afterwards is not the thing that caused the problem. - Fresh diesel goes in, and then the system gets primed. - When it's started, our technicians check it runs correctly on fresh diesel. Then it is ready to drive away. Our engineers do all of this wherever your car has ended up, which means it never has to be taken to a workshop, and if it has been noticed early, it is very rare for there to be long-term damage. Hardly ever the trouble, the location. On-street is the commonest spot we work, and a tight parking spot is far preferable to a motor that has been driven somewhere more handy. What does help, when you call from close to Hope Church Ferndown, is three things: the side the filler is on, whether our van can pull up next to without blocking the road, and whether anything has run since you filled up. Then your Audi A3 gets drained, the filter changed where a usable one exists, the fuel lines purged and fresh fuel put through the full circuit — since by now the worst of that is in the lines, not that tank. ## A different job: AdBlue in a diesel tank around Tricketts Cross If what got in was AdBlue rather than petrol, the opening rule is the same — never fire it up — but the fault isn't. The protection a fuel system relies on gets taken away by petrol, which weakens the diesel. AdBlue? Urea dissolved in water. Tip that in with the diesel and you get corrosion instead, plus build-up. Both are ours. There is a separate Tricketts Cross page for AdBlue removal, with the details on it — including the reasons it frequently turns out to be the worse of the two. A throttle gone dead, white smoke, a lumpy idle, clattering: that's a wrongly fuelled diesel BMW 1 Series telling you what's wrong. Never restart the car to find a better place — switch off where you have stopped, by Heatherlands Centre or anywhere else. ## What a petrol-in-diesel fuel drain costs around Tricketts Cross We cannot put one number on this page honestly, as the job isn't one job. What moves it: - This is the main one: whether the motor has been run, or driven. - How much of the wrong fuel got in, judged against how much that tank can hold. - AdBlue or petrol, whichever went in. - Whether a van can safely get to your car and work on it, which depends on where your car is. Tell us the vehicle, the amount and whether it has run, and you'll get a firm answer instead of a range. If it's not urgent — your car is at home and going nowhere — is fine too. ## Petrol in diesel: frequent questions around Tricketts Cross ## I'm on a forecourt around Tricketts Cross. Can you drain it on the spot? Yes — forecourts are where a fair share of this gets done. Tell us which one you are at when you ring and we'll tell you if our engineers can work there. With the site's permission we visit Texaco and the other forecourts locally all the time. ## Is there a safe quantity of petrol in a diesel? Whether your engine has run counts a lot more, though the proportion matters too, rather than the litres. What settles how much work is needed is whether that mixture has been pulled through the fuel system — since even though five litres in an almost empty tank is a different situation from five in a full one, either way that is the query. ## I drove it after putting petrol in my diesel. What next? Somewhere sensible, then stop, then switch off and leave it off. Driving is what takes the issue from that tank into the pump and injectors — but it is salvageable far more commonly than people fear, and the single most valuable thing you can do now is not restart the car. ## Is a fuel drain going to void my warranty? A manufacturer's warranty withstands a drain then flush done to a correct standard, which is no change at all. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause an argument with one. ## Adding two-stroke oil, then driving home What petrol has thinned isn't replaced by two-stroke oil, which is an old remedy for a distinct problem. So no. Petrol remains in that tank afterwards, whatever else goes in, and your pump gets no reprieve from it. ## Main dealers and petrol in a diesel Not at all. Our technicians drain and clean the car wherever it is, so there's no need to take it to a dealership. ## You, and the vehicle, still together? Shut off is how the car remains. If you have already driven the car, pull over somewhere safe, switch it off then leave it off. Cold, parked, going nowhere: that is the best place to be in. People fear this a lot more than they need to. Call-out fuel draining around Tricketts Cross and throughout Dorset — at the roadside, on the forecourt or at home.
