Most calls from this area come from supermarket forecourts at the end of the working day, when the pumps are busy and the driver is thinking about something else. The A75 shapes misfuelling here. A large share of the traffic is holiday and freight movement heading for a sailing, in hire cars, motorhomes and tractor units, on an unfamiliar route, often at unsociable hours with a clock running. The asymmetry is physical. A petrol nozzle fits a diesel car; a diesel nozzle usually will not fit a petrol one. That single difference in nozzle diameter accounts for most of the imbalance in the jobs we attend. When it happens: Tied to sailing times rather than rush hours, which is why the overnight and early-morning share is much higher here than on a comparable English town's roads. ## I just put petrol in my diesel car near Thornhill: what to do The most common misfuel, and the one with the most to lose by starting the engine. ## Three questions that tell us most of the story Did the engine start? How far did it run? Which fuel went in? The first two describe how far contamination has travelled along tank, lift pump, filter, high-pressure pump and injectors. The third describes how it behaves along the way: petrol thins the lubrication a diesel pump needs, while diesel in a petrol engine fouls plugs and injectors instead. ## Step by step Freeze, then think The reflex is to start up and drive somewhere sensible. Resist it. Nothing about the situation gets worse while the engine stays off. - Where you are is fine A forecourt bay, a kerb, a car park: all workable. Only move if staying put is genuinely dangerous. - Hazards and a quick word Switch the hazards on and tell anyone who needs to know — cashier, passengers, the driver behind. - Ring 01293 248666 with four facts Make, wrong fuel, rough quantity, started or not. Those four facts set the price you are quoted before dispatch. - A technician arrives equipped Pump, sealed waste drum, fresh fuel and priming kit all come in the van. Nothing is towed. - Drive off, document in hand About an hour for a typical job, then a waste transfer note for the old fuel, which is worth keeping. ## The full page for this - Petrol in diesel in Thornhill ## I just put petrol in my diesel car elsewhere - i just put petrol in my diesel car near Dumfries town centre - i just put petrol in my diesel car near Georgetown - i just put petrol in my diesel car near Lochside - i just put petrol in my diesel car near Locharbriggs - i just put petrol in my diesel car near Heathhall - i just put petrol in my diesel car near Maxwelltown - i just put petrol in my diesel car near Troqueer - i just put petrol in my diesel car near Summerhill ## Related searches - Petrol in diesel car - Petrol in a diesel car - What happens if you put petrol in a diesel car - Put petrol in diesel car - Petrol in diesel engine - Putting petrol in a diesel car - Petrol in diesel - Petrol in a diesel engine ## Four point eight, and why it is not five 2,190 Trustpilot reviews average 4.8. Happy customers write about patience: a technician who explained each step instead of hurrying, at an hour when nobody wanted to be standing on a forecourt. Most of the missing tenth is money. That is understandable, so the numbers sit in plain sight — call-out £89 to £199, drain £199 to £1,999 — and every figure is agreed by phone first, never revealed on arrival. ## Questions we get asked **Do I need to stay with the vehicle?** Usually yes, so we can hand it back to you running. If you cannot stay, say so on the call and we will work out how to do it. **What if it is not safe to drain where I am?** Then we tell you that on the phone rather than after arriving. Being told honestly costs nothing; being told on arrival costs a call-out. **Do you cover all of DG1, DG2 and the surrounding districts?** Yes, from one rota — so being at one edge of the area rather than the other changes the arrival window, not the price. **What if I have already driven it?** Still call. Most vehicles driven a short distance are recoverable. Tell us how far you got, because it changes the kit we bring. ## Who you are dealing with Wrong Fuel Dumfries is a service by Forecourt Assistance.
