1,000+ Commercial Grades
SERVO offers 1,500+ formulations across automotive, industrial and marine — a one-stop lubrication solution. First national oil company in India approved by MAN and Wärtsilä for marine engines.
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.
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
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.
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.
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.
Cost of Downtime.
Power of Prediction.
An unscheduled marine engine shutdown can cost ₹20–30 lakhs per day. Servo's structured monitoring package keeps lubricant and equipment health in plain sight — sample collection, trend analysis and expert interpretation, end to end.
Oil Condition Monitoring
Tracks acid number, viscosity drift and metal wear traces — sample by sample.
Trend Graphs & Alerts
Early-stage degradation detection across cylinder, system and TPEO oils.
Predictive Maintenance
Plan overhauls before failure — downtime can cost ₹20–30 lakhs per day.
