Exocet® Anti-Bug For Gas Oil

Exocet Anti-bug

Exocet Anti-Bug is used for the control of microbiological contamination. The first sign of microbiological contamination ( the ‘diesel bug’) is often continuous blocking of filters with a slimy substance, which can range in colour from black to light brown.

Exocet Anti-Bug can be dosed into any fuel at the time of delivery as a ‘maintenance’ dose to inhabit microbiological activity in clean tanks.

1 Litre treats 2500lts at a kill dose and 50,000 litres as a maintenance dose.

Product is available in volumes of 200ml and 500ml.

Exocet® Diesel Supreme

Exocet Diesel Supreme

Exocet Diesel Supreme fulfils two functions:

  1. to act as an additive package for unadditised, terminal-sourced DERV (basic EN590 diesel)
  2. to upgrade retail diesel to premium grade fuel

Exocet® Gas Oil Extra

Exocet Gas Oil Extra

Formulated to allow modern diesel engines calibrated on EN590 DERV to run on red diesel, Gas Oil Extra also compensates for some of the potentially harmful effects of a higher FAME content. Also enhances performance of older vehicles.
