Understanding Low and Ultra-Low Marine Oil

Since January 1st, 2020 the International Maritime Organisation has implemented a global cap of 0.50% on sulphur in marine fuel emissions. This action should reduce the amount of sulphur oxide in the air preventing further damage to the ozone layer. To power your superyacht there are two different types of low-sulphur fuel you can use.

LSMGO – Low-Sulphur Marine Gasoil This fuel has a sulphur content of less than 0.1% which allows it to be used in EU ports or Emission Control Areas (ECAs), which meet the limit corresponding to the IMO regulations.
AGO- Automotive Gasoil Containing 97% less sulphur than MGO, AGO was developed to reduce diesel emissions and help to cut pollution. Originaly developed for use with shoreside engines, AGO has become the fuel of choice for yachts due to its ultra low sulphur content.

Identifying Bunker Fuel

There are a variety of different names in the marine oil industry and this can make identifying the right bunker fuel for your yacht confusing. Peninsula is here to help identify a helpful list of alternative names and abbreviations for marine oil. 

MGO Marine Gas Oil
MDO  Marine Diesel Oil
IFO Intermediate Fuel Oil
MFO  Marine Fuel Oil
HFO Heavy Fuel Oil
Automotive Gasoil - AGO

Also known as diesel, AGO is a by-product of crude oil. This fuel is less flammable compared to other petroleum products and is more dependent and efficient when running heavy-duty equipment making it a suitable choice for larger vessels.


Finding the right marine fuel solution can not only provide financial benefit, but it can also ensure the longevity and efficiency of the yacht’s engine.This glossary will prove valuable in keeping you up to date with the latest marine fuel solutions. 

AGO Automotive Gasoil
MGO Marine Gasoil
LSMGO Low-Sulphur Marine Gasoil
MDO Marine Diesel Oil
ULSD Ultra-Low Sulphur Diesel
