What happens to the contaminated fuel?

We take it away and it's disposed of by a licensed waste carrier. Pouring it away or leaving it on site is illegal — beware of anyone who offers to.

Do you work 24 hours?

Yes — 24 hours a day, 7 days a week, 365 days a year. No surcharges for nights, weekends or bank holidays.

Do you cover hire cars, lease cars and company vehicles?

Yes. We'll give you the paperwork the hire or lease company needs, and we can bill fleet and rental businesses directly on account.

How it works

From panic to back on the road

Watch what happens after you call. Most drains take 30 to 45 minutes once our technician arrives — and you can see what's in your tank at every step.

Step 1 of 6

Oops — wrong nozzleIt happens to around 150,000 UK drivers a year. Stop. Don't start the engine.

What we fix

Every kind of misfuel, at the roadside

One call covers cars, vans, motorhomes, fleet vehicles and HGVs.

Why it matters

Five minutes now saves thousands later

The difference between a quick drain and a new fuel system is usually whether the engine ran.

Never again

Read the nozzle, not the colour

UK pumps are usually green for petrol and black for diesel — but not always. The label is what counts.

E10 · E5

Unleaded petrol · usually green

If your car is a diesel, a green nozzle should never go near it. Super unleaded is usually labelled E5.

B7 · B10

Diesel · usually black

The wider diesel nozzle doesn't fit most petrol fillers — but it does fit some. Check the label every time.

FAQs

Wrong fuel questions, answered

All FAQs

I've put the wrong fuel in. What do I do right now?+

Don't start the engine — don't even turn the ignition on, and on a keyless car keep the key away from it. Put the car in neutral and, with help, push it clear of the pump. Tell the forecourt staff, then call us. Most cars are back on the road within an hour of the technician arriving.

How much does a wrong fuel drain cost?+

Our fixed price starts at £199 if the engine hasn't been started, including draining, flushing, 10 litres of the right fuel and legal disposal of the contaminated fuel. There's no call-out charge and no extra for nights, weekends or bank holidays.

How quickly can you get to me?+

Our target is to reach most drivers within 45 to 60 minutes. Rural areas and busy periods can take longer; we'll give you a real arrival time on the phone and keep you updated.

Do you come to motorway services, supermarkets and car parks?+

Yes. We drain cars on forecourts, at motorway services, in supermarket and retail park car parks, outside your home or office — wherever the car is safely parked.

Can I just drive it to a garage?+

Please don't. Driving circulates the wrong fuel through the pump and injectors, which is where expensive damage happens. A mobile drain comes to you and costs far less than recovery plus a garage repair.

Will my car insurance cover wrong fuel?+

Some policies and breakdown covers include misfuel; many exclude it or cap it. Check your documents. We give you an itemised receipt and job report so you can claim if you're covered.

Is it safe to drain fuel on a petrol station forecourt?+

Yes, when it's done properly. We use sealed, ADR-compliant pumps and containers, spill kits, and follow the forecourt's safety rules. If the site manager prefers, we'll move the car a short distance first.
