Marine Gas Oil (MGO): Refined from crude oil, Gas Oil is a middle distillate liquid. There are two recognised standards of gas oil:
Class A2/ULSGO: Class A2 gas oil is also known as ULSGO (ultra-low sulphur gas oil). Class A2 meets the current BS2869 and ISO 8217 specifications and has a maximum sulphur content of 10ppm (0.001%).
Class D: Class D has a maximum sulphur content of 1000ppm and meets the current BS2869 and ISO 8217 specifications. Also known as 1000ppm, 0.1% or LSGO (low sulphur gas oil).
Shell GTL (Gas To Liquid): Certas Energy is the sole distributor of Shell GTL Fuel in the UK. This paraffinic fuel offers a cleaner-burning alternative for use in diesel engines. Suitable for off-road applications, it both lowers emissions and improves air quality and can be used as a direct replacement for conventional dielse fuels with no modifications needed.
The GTL technology lowers local emissions of regulated pollutants: Particulate Matter (PM), Nitrogen Oxide (NOx), Carbon Monoxide (CO) and Hydrocarbons.
