TECHNOFLUID DIESEL ENGINE OILS
Industrial Engine Oils
(For Generators, Pumps & Industrial Engines)TECHNOFLUID Industrial Engine Oils are high-performance diesel engine lubricants formulated to meet the demanding requirements of stationary and mobile industrial engines.
Manufactured from premium quality base oils and advanced additive technology to provide excellent protection under continuous and heavy-duty operating conditions.
Designed to control deposits, neutralize acidic combustion by-products, and protect engine components from wear and corrosion.
Suitable for naturally aspirated and turbocharged diesel engines operating on high-sulphur and low-sulphur fuels.
Available in multiple viscosity grades and performance levels to meet diverse industrial engine requirements.
Key Benefits
Excellent detergency and dispersancy keep engines clean and free from sludge.
Superior wear protection extends life of pistons, rings, liners, and bearings.
High Total Base Number (TBN) helps neutralize acidic combustion products.
Good thermal and oxidation stability ensures long oil life in continuous operations.
Reduces oil consumption and minimizes downtime.
Protects engines against rust and corrosion during idle or standby periods.
Ensures smooth engine operation and consistent power output.
