Wrong fuel recovery costs in the UK vary significantly depending on four key factors: the type of misfuelling (petrol in diesel, diesel in petrol, or AdBlue contamination), whether the engine was started, the type and size of vehicle, and your location. This guide gives you a clear breakdown of typical costs for each scenario so you know what to expect before you call.
If you put petrol in a diesel car and did not start the engine, the recovery cost is at the lower end of the scale. A specialist will drain the contaminated fuel from the tank, flush the fuel system, replace the fuel filter, and refill with clean diesel. For a standard car, expect to pay £99–£180. For a van or larger vehicle, costs are typically £150–£250. This is the best-case scenario — the engine is undamaged and you can continue your journey within 30–45 minutes.
If the engine was started after misfuelling, costs escalate dramatically. The fuel pump, injectors, and common rail system may all need replacing. A partial fuel system flush (engine started briefly) typically costs £300–£800. A full fuel system replacement following extended running can cost £2,000–£8,000+ on modern diesel vehicles. Some vehicles are written off entirely. This is why the single most important rule after misfuelling is: do not start the engine.
Diesel in a petrol car is less common and generally less damaging than petrol in diesel. Petrol engines do not rely on fuel for lubrication in the same way. If the engine was not started, a fuel drain and flush costs £99–£200 for a standard car.
If the engine was started with diesel in a petrol car, the diesel can foul the spark plugs and catalytic converter. Repair costs depend on how long the engine ran. Expect £200–£500 for minor contamination and up to £1,500 if the catalytic converter needs replacing.
AdBlue contamination is the most serious misfuelling scenario. AdBlue is highly corrosive to diesel fuel system components. If the engine was not started, a specialist flush costs £300–£600. If the engine was started, full fuel system replacement can cost £1,500–£3,000+. Some vehicles require replacement of the entire fuel system.
Many comprehensive car insurance policies include misfuelling cover. Check your policy documents for 'misfuelling' or 'wrong fuel' cover. If covered, your insurer will typically arrange recovery directly or reimburse you for the cost. Keep all receipts.

Petrol in a diesel engine is the UK's most common misfuelling mistake — over 150,000 incidents every year. This guide explains exactly what happens to your engine, how serious the damage is, and what you must do (and must NOT do) the moment you realise your mistake.
Putting petrol in a diesel car — or diesel in a petrol — is more common than you think. The good news is that if you act quickly and follow the right steps, you can often avoid serious engine damage.
The short answer is no — but the full picture is more nuanced. This guide explains what happens if you accidentally start the engine after misfuelling, how far you can drive, and when it is safe to continue your journey after wrong fuel recovery.
