At Topaz, we understand the demands placed on diesel engines in both commercial and industrial applications. Our specialized line of diesel engine oils, including both mineral and synthetic formulations, is engineered to deliver exceptional protection, performance, and reliability in the harshest operating environments.
Diesel engines operate under higher loads, pressures, and temperatures compared to gasoline engines. That’s why Topaz diesel oils are formulated using advanced additive technologies and high-quality base oils to ensure:
✅ Extended engine life through superior wear protection
✅ Clean engine internals thanks to strong detergency
✅ Improved soot handling and oxidation resistance
✅ Stable viscosity under extreme working conditions
✅ Compatibility with emissions control systems (EGR, DPF)
Our mineral-based diesel oils are ideal for conventional and high-mileage diesel engines, offering cost-effective and proven lubrication performance.
High-performance mineral oil with excellent thermal stability, designed for modern turbocharged diesel engines.
Suitable for mixed fleets and older diesel engines. Provides improved wear protection and deposit control.
A reliable choice for naturally aspirated and lightly turbocharged diesel engines. Offers basic protection and long oil life.
A balanced formulation for high-output engines operating in tough conditions. Outstanding soot control and engine cleanliness.
Designed for both on-road and off-road applications. Improves engine durability under medium to high loads.
A cost-effective solution for older diesel engine technology. Provides adequate protection for extended drain intervals.
Our synthetic diesel engine oils are formulated for maximum performance, fuel efficiency, and protection, particularly in severe service conditions and modern emission-controlled engines.
Synthetic formulation for increased oxidation stability and cleaner engine operation. Ideal for high-load fleet use.
