Star Mariner Eliminator helps protect against the sludge build-up and contamination that can lead to blocked filters and reduced engine performance.

By stabilising fuel and supporting long-term storage quality, it plays a vital role in preventative maintenance routines for marine gas oil, including fuels with FAME content.

Works with conventional diesel, HVO, and blended fuels – giving you flexibility as your fleet transitions to lower-carbon alternatives.

Whether you’re laying up or operating in tough conditions, Star Mariner Eliminator helps keep your fuel stable and your systems running smoothly – and diesel bug problems firmly at bay.

Applications

  • Fuel systems: Reduces the risk of sludge build-up and filter blockages, helping maintain engine performance.
  • Long-term fuel storage: Supports stability and helps maintain the quality of marine gas oils, including those with FAME content.
  • Closed-loop fresh water cooling systems: To help manage contamination and maintain system performance (see below).

Anti-bacterial water treatment: marine diesel engine enclosed cooling systems

Star Mariner Eliminator is formulated to control the growth of Nitrite Reducing Bacteria (NRBs) in marine diesel engine water cooling systems. Its efficacy remains active at temperatures of up to 95°C and it is non-corrosive to both ferrous and non-ferrous materials.

Disclaimer
Star Mariner Eliminator is a fuel treatment additive designed to support quality and maintenance. It is not classified or marketed as a biocide under current regulations. The product functions as a stabiliser and efficiency enhancer for marine diesel fuel systems.

What specific problem does diesel bug cause in a vessel's fuel tank?

Diesel bug, a microbial contamination in fuel tanks, primarily causes clogged fuel filters, corrosion of fuel tanks and lines, and reduced engine performance. This contamination can lead to engine failure, expensive repairs, and potential fuel leaks, creating significant issues for vessels.

Is Star Eliminator a biocide?

Eliminator is a fuel treatment additive formulated to support diesel quality and system maintenance. It is not intended to function as, or be classified under regulations as, a biocide. Instead, it acts as a stabiliser and performance enhancer for diesel fuel systems.

What is HVO fuel?

HVO (Hydrotreated Vegetable Oil) is a renewable diesel alternative produced from waste materials like used cooking oil and animal fats. Unlike traditional biodiesel (FAME), HVO is a pure paraffinic fuel with excellent stability, very low water uptake, and minimal risk of microbial contamination.

It can be used as a direct drop-in replacement for conventional diesel without engine modifications, and is increasingly popular in marine applications as operators work toward emission reduction targets.

Can Star Mariner Eliminator be used with HVO fuel?

Yes, Star Mariner Eliminator works effectively with HVO fuel, HVO blended with conventional marine diesel, and pure marine gas oil.

Because HVO is naturally more stable and less prone to contamination than conventional diesel or FAME-blended fuels, it requires less intensive treatment. However, Star Mariner Eliminator remains effective for preventative protection in HVO systems, particularly in mixed-fuel environments where vessels may alternate between HVO and conventional diesel, or where fuel quality during bunkering cannot be guaranteed.

Whether you’re running pure HVO, blends, or considering a transition to renewable diesel, Star Mariner Eliminator provides consistent fuel system protection across all marine diesel types.

To protect against diesel bug manifestation issues, we recommend a dose rate of 1 litre Star Mariner Eliminator to 4,000 litres (4 tonnes) of marine diesel fuel.

For anti-bacterial water treatment in marine diesel engine enclosed cooling systems, we recommend 1 litre of Star Mariner Eliminator to 4,000 litres of water.
