The Service

Professional in - Process Details

Why It's Serious

Diesel fuel lubricates your high-pressure fuel pump. Petrol acts as a solvent and strips that lubrication completely. Even a small percentage of petrol contamination causes metal components to grind against each other, generating metallic debris that flows through the entire fuel system.

If the engine is started and run on contaminated fuel, the high-pressure pump, injectors, common rail, and pressure relief valves can all be destroyed — resulting in repair bills of £2,000–£8,000. A £200–£400 drain done immediately prevents all of this.

FAQs

Common Questions

How much petrol can be in my diesel before it's serious? expand_more
Even a small amount of petrol — as little as 5% contamination — is enough to cause damage to the fuel pump in a modern high-pressure diesel system. It's not about the quantity. If you added any petrol at all, do not start the engine. Call us immediately.
I started the engine briefly — is it ruined? expand_more
Not necessarily. We recover a high percentage of vehicles that have been briefly started. However, the drain and flush process will be more intensive and may cost slightly more, as contaminated fuel will have entered the injectors and fuel lines. Turn it off immediately and call us — the sooner the better.
Will my car insurance cover this? expand_more
Many comprehensive car insurance policies include misfueling cover. Some breakdown policies also cover it as a standard or optional add-on. We provide a full, itemised VAT receipt upon completion of every job which you can submit to your insurer.
How long does the drain take once you arrive? expand_more
For a standard petrol-in-diesel drain where the engine was not started, the process typically takes 30–45 minutes from our arrival to you driving away. If the engine was started, it may take slightly longer due to the deeper flush required.
Do you add new diesel after the drain? expand_more
Yes. After the complete drain and flush, we add enough fresh diesel to fully prime the system and allow the engine to start and run normally. We confirm the engine runs correctly before we leave your side.
