Base stock selection
High-performance fully synthetic, VHVI synthetic, synthetic blend or premium mineral, chosen against the viscosity grade, the operating temperature range and the drain interval the fluid has to survive.
Precision at the
Molecular Level.
Every PX98 premium engine oil begins with carefully selected premium base stocks and highly-advanced additive systems.
Three Stages, One Finished Fluid.
Additive system
Detergents, dispersants, friction modifiers, anti-wear chemistry and VI improvers are balanced to the target approval, including reduced-SAPS packages where after-treatment systems demand it.
Verification
Each finished good undergoes rigorous quality control before release, so what leaves the plant performs the way the specification says it will.
What it delivers
Stronger Film.
Stronger Film.
Cleaner Engine.
Quicker lubrication during cold starts, stronger oil film under extreme loads, outstanding shear stability, and formidable oxidation resistance that keeps today's turbocharged engines running at peak efficiency.
- Cold start
- Rapid oil circulation at low ambient temperature, protecting the engine in the first seconds after ignition.
- Film strength
- A durable lubricating film under extreme load and boundary lubrication conditions.
- Shear stability
- Viscosity held in grade throughout the service interval, not just on the day it is filled.
- Oxidation resistance
- Resistance to thermal breakdown, deposit formation and sludge under sustained heat.
- After-treatment
- Low and reduced-SAPS chemistry that protects DPF, DOC and SCR systems on modern diesels.
Ten Things We Engineer For.
Future-ready synthetic technology
Next-generation additive systems
Exceptional viscosity stability
Timing chain wear protection
Turbocharger protection
Low speed pre-ignition control
Piston deposit control
Superior oxidation resistance
Improved fuel economy
Enhanced energy conserving
Modern low SAPS engine oil formulation
Protecting the Engine and the Exhaust
Modern Euro VI diesels run DPF, DOC, SCR and EGR systems that conventional high-ash chemistry will foul. PX98 heavy duty oils use low and reduced-SAPS additive technology so soot handling, piston cleanliness and extended drain capability arrive without shortening after-treatment life.
