What happens if you put 1 litre of petrol in a diesel car- # What happens if you put 1 litre of petrol in a diesel car What happens if you put 1 litre of petrol in a diesel car? A splash still matters in a modern diesel. Do not start it and do not top it up hoping to dilute it — call first. Call 01293 248666 — a mobile technician comes to the vehicle anywhere across TS1 and TS3 to TS8. Call-out £89 to £199, drain £199 to £1,999. ## Straight answer on what we are A mobile fuel drain operation covering TS1 and TS3 to TS8. No garage, no forecourt, no Middlesbrough address. A technician and a van, dispatched by people who know the area, reached on 01293 248666. If that is not what you need, we will say so on the call rather than take the booking. **Search**: what happens if you put 1 litre of petrol in a diesel car **What it is**: Small amount of petrol in diesel **Where we cover**: TS1 and TS3 to TS8 **Cost**: Call-out £89 to £199, drain £199 to £1,999, quoted in full before we travel **Time on site**: About an hour **Hours**: 24 hours, every day **Phone**: 01293 248666 ## What happens if you put 1 litre of petrol in a diesel car: what to do Five litres, twenty litres, a splash — why the amount matters less than the key. ## Where the damage actually occurs Not in the tank. The tank is just where it starts. Damage happens at the high-pressure pump, which relies on the fuel itself for lubrication and has very tight tolerances, and then at the injectors downstream of it. Reaching either requires the engine to have run, which is why a car coasted to a halt on the forecourt is almost always a call-out and nothing more. ## Step by step First: nothing Do not turn the key, do not turn the ignition to accessory, do not try the radio. The engine has not run on the wrong fuel yet and that is worth protecting. - Second: stay where you are Unless you are somewhere dangerous. A vehicle that has not moved is a vehicle whose contamination is still all in one place. - Third: make the call 01293 248666. Four questions — vehicle, which fuel, roughly how much, did it run — and you get a price and a window before anyone sets off. - Then we work where the car is Extraction, line flush, fresh fuel, prime, run-up and a check. Nothing needs recovering anywhere. - And the waste goes properly Registered carrier, waste transfer note, correct consignment. Keep the note; it is the document that protects you, not us. ## The full page for this - Small amount of petrol in diesel in Middlesbrough ## Related searches - I put 5 litres of petrol in my diesel car - 20 litres of petrol in diesel car - Small amount of petrol in diesel car - Small amount of diesel in petrol car - 10 litres of petrol in diesel car - Small amount of petrol in diesel engine - 15 litres of petrol in diesel car - 5 litres of diesel in a petrol car ## What customers say 4.8 out of 5 from 2,190 Trustpilot reviews. The thing reviewers mention most is technicians who stay calm and professional with someone who is having a bad day, followed by how quickly a van turns up. The most common criticism is price, so here it is plainly rather than buried: the call-out is £89 to £199 and the drain £199 to £1,999, and the full figure is given on the phone before anyone travels. ## Questions we get asked **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. **Do you cover all of TS1 and TS3 to TS8?** 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 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 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. ## Who you are dealing with Wrong Fuel Middlesbrough is a service by Forecourt Assistance.
