What are the dangers of mixed fuel?

In brief

Treat mixed fuel like petrol: highly flammable at normal temperatures, harmful if swallowed and it enters the airways, and toxic to aquatic life. Call 07950 582635 or send an enquiry.

Fire and explosion risk of mixed fuel

Mixed fuel has a flash point often below normal air temperatures, even with a small share of petrol. Keep it away from flames, sparks, welding and hot surfaces, and store it in ventilated, bunded areas.

Mixed fuel and the environment

Fuel is toxic to aquatic life and spreads across water. Treat it as a petrol spill: remove ignition sources, ventilate, protect drains and report anything that could reach water.

Mixed fuel in practice

Mixed fuel is the most common waste fuel from vehicle depollution and misfuel drains, and it usually still has recoverable value.
