Technical Detail
Distillate vs residual
Unlike VLSFO and HSFO which are residual fuels (heavy, viscous, require heating), LSMGO is a distillate — essentially a marine diesel, lighter and cleaner-burning. It requires no onboard heating, separates less readily, and behaves more predictably than residual grades.
ECA compliance
In ECAs, vessels must use fuel with ≤0.10% sulphur unless equipped with certified SOx-reducing technology. LSMGO is the default compliance fuel, particularly for vessels without scrubbers or whose scrubbers are not approved for ECA operation.
Auxiliary engine use
Even on vessels running VLSFO or HSFO for main propulsion, auxiliary engines (generators, boilers) often run on LSMGO, particularly during port stays and ECA operations. This creates steady demand independent of main-engine fuel choice.
Quality and price
LSMGO is distillate, so more expensive per tonne than residual VLSFO — but burns cleaner, requires less maintenance on separators and injectors, and is more reliable in cold-climate operations. Many operators use LSMGO consumption to reduce long-term engine wear costs.

Frequently Asked Questions
Do I need LSMGO if I run VLSFO?
Most deep-sea vessels carry both. VLSFO for main engine on passage; LSMGO for ECA transit, port operations, and auxiliary engines. Tank segregation and changeover procedures are routine.
Is LSMGO the same as MGO or ULSD?
LSMGO is MGO (marine gas oil) at 0.10% sulphur. Standard MGO can be higher sulphur. ULSD (ultra-low sulphur diesel, 10-15 ppm) is road-fuel grade and generally not required for marine use unless specifically nominated.
Can I run my main engine on LSMGO only?
Yes, many smaller vessels do, particularly in ECAs or for coastal operations. Engine OEMs typically permit this; some engines require specific fuel treatment adjustments. Cost per tonne is higher than VLSFO.
What's the changeover procedure for ECA entry?
Standard procedure involves gradually transitioning fuel supply to the auxiliary day tank and main engine service tank before ECA entry, allowing lines to flush. Written procedures are mandated by MARPOL and must be logged.
