General Misfueling Questions
Q: I’ve put the wrong fuel in my car – what should I do?
A: Stop fuelling immediately and do not turn on the ignition. Starting the car can spread the wrong fuel through your system. Call us right away—we’ll dispatch a mobile fuel drain unit to your location.
Q: Can you remove the wrong fuel on-site?
A: Yes, all of our vans are fully equipped for on-site fuel draining and flushing. Whether you're at a petrol station, roadside, work, or home—we come to you.
Q: How quickly can you get to me?
A: We aim to be with you within 30 to 60 minutes, depending on your location and local traffic conditions. We operate nationwide, 24/7.
Q: Is misfuelling common?
A: Yes—over 150,000 drivers in the UK misfuel every year. You're not alone, and it’s easily fixed if caught early.
Petrol in a diesel Car
Q: What happens if I put petrol in a diesel car?
A: Petrol reduces the lubrication your diesel engine relies on. This can damage the fuel pump, injectors, and engine if the car is started. We recommend a full fuel drain and flush before turning the key.
Q: What are the signs of petrol in a diesel engine if I already drove?
A: Common signs include:
- Engine knocking or misfiring
- Thick smoke from the exhaust
- Poor acceleration or stalling
- Warning lights on the dash
Stop the vehicle and call us immediately.
Diesel In A Petrol Car
Q: What are the risks of putting diesel in a petrol car?
A: Diesel can clog fuel filters and foul spark plugs. If undrained, it may prevent the engine from starting or cause it to misfire. It’s important to drain and clean the fuel system as soon as possible.
Q: Will my car be okay if I didn’t start it?
A: If you haven’t started the engine, you’ve likely avoided major damage. A simple fuel drain and refill should be enough.
Adblue Contamination
Q: I put AdBlue in the diesel tank – what now?
A: Do not start the engine. AdBlue is highly corrosive and can crystallise, damaging your fuel system and engine. Our team can remove all traces and flush the system safely.
Q: What if I already drove with AdBlue in the tank?
A: Stop the vehicle immediately. Continued driving may cause severe damage. We can assess the extent of contamination and advise on next steps.
Q: Can you remove AdBlue from diesel tanks?
A: Yes. We provide professional AdBlue removal and system flushing with eco-safe disposal. Call us for urgent assistance.
