Fuel Polishing

Fuel Polishing is more important than people often realise; clean fuel means reliable performance of your systems, vehicles and critical infrastructure.

Over time, diesel stored in tanks can degrade. It starts to collect water, sludge, microbial growth, and other contaminants that can clog filters, corrode components, and seriously impact engine efficiency. That’s where fuel polishing comes in.

Diesel fuel polishing is a multi-stage filtration and cleaning process. It circulates the fuel through high efficiency filters and water separators, removing particulates, microbial contamination, and emulsified water. The goal? Restore your fuel to optimal condition without replacing the entire tank contents.

This process is especially important for backup generators, marine vessels, heavy machinery, and any system that stores diesel for extended periods. When diesel sits, it stratifies and oxidises, leading to poor combustion and even engine failure if left unchecked.

Fuel polishing not only helps extend the life of your fuel and equipment, but it also improves reliability and compliance with maintenance standards. Regular polishing reduces the risk of costly downtime, hard starts, and clogged fuel lines; plus, it keeps your system running cleaner and more efficiently.

If you rely on diesel, fuel polishing isn’t just a nice idea; it’s a smart, preventative maintenance move. Think of it as a detox for your tank. 

You might not see it happening, but your fuel is permanently degrading so it's important you stay on top of it.
