How do you stop sediment building up in avgas?
In brief
Keep fill caps and vents sound, use filtered fill points, and clean tanks periodically. Prevention costs far less than dealing with sediment in avgas once it has happened. Call 07950 582635 or send an enquiry.
How sediment in avgas happens
Rust and scale from steel tanks, dust and grit through open fill points and vents, and degraded fuel all settle to the bottom of tanks over time.
Checking for sediment in avgas
Particles or grit at the bottom of a sample jar, hazy fuel, and filters that block quickly.

Avgas in brief
Avgas (aviation gasoline, or aviation spirit) is a petrol-type fuel for piston-engined aircraft. Volumes are usually small (drums, bowser residues, tank bottoms at airfields), so terms depend heavily on volume, contamination and access.
