About SERVO · Energise Your Voyage

Charting a Legacy
of Excellence at Sea

For over four decades, IndianOil SERVO has been the unwavering compass of the global marine industry — backed by Asia's most advanced R&D facility and a 27% share of India's finished lubes market.

The Anchor of Trust

From Main Cylinder Oil and System Oil through TPEO and auxiliary applications, every Servo formulation is engineered to deliver robust protection and uncompromised efficiency — primed for cargo ships, naval craft and the most agile offshore vessels.

Pioneer in OEM Approvals

First Indian oil company approved by global maritime giants — MAN Energy Solutions, Wärtsilä and WinGD — across both 2-stroke and 4-stroke marine engine portfolios.

Environmentally Acceptable Lubricants

Servo R&D is actively formulating biodegradable EAL grades for stern tubes and sea-facing equipment — meeting U.S. VGP requirements without compromising on performance.

IMO 2020 Compliance

A Clear Strategy
for the 0.50% S Era

The International Maritime Organization caps marine fuel sulphur at 0.50% globally (0.10% in Emission Control Areas). IndianOil supplies fully compliant fuels and matched lubricants for every fuel regime.

3.50% → 0.50%Global sulphur cap, since 01 Jan 2020
0.5% S

VLSFO — Very Low Sulphur Fuel Oil

  • Produced from Low-Sulphur Residue components from refining processes
  • Viscosity range 220–300 cSt
  • Specs: ISO 8217 : 2017 RMG380
0.1% S

LS MGO — Marine Gas Oil (HFHSD)

  • Differentiated grade for Merchant & Naval vessel distillate needs
  • ECA-compliant ultra-low sulphur fuel
  • Specs: ISO 8217 : 2017 DMA & MIL-DTL-16844M

Lubrication guidelines updated for both 0.50% VLSFO and 0.10% ULSFO operation — see the Engine Oil Selection Guide below.

Engine Oil Selection Guideline

Match the Grade to Your Fuel

Lubrication strategy aligned with IMO 2020 fuel regimes — from HSFO through VLSFO to ECA-zone ULSFO. Backed by MAN ES, WinGD and Wärtsilä approvals.

Every Drop Counts

The Most Powerful
Machines on Earth
Run on Lubricants.

A large cargo ship generates 60,000+ horsepower on just a few hundred litres of cylinder oil per day. The wrong formulation can raise friction by 2% — costing a fleet millions in fuel annually.

From the ports of Singapore to the Arabian Sea — every ship, every sea, every spec, covered.
