Introducing ultEbase® -
A New Class of Synthetic Base Oil
ultEbase® is a globally patented, Group V synthetic base oil platform developed by SantoLubes® to push the boundaries of what’s possible in gear and compressor lubrication. Engineered with the lowest elastohydrodynamic (EHD) shear strength ever recorded – up to 33% lower than PAOs and PAGs – ultEbase® delivers superior energy efficiency, high viscosity index, and industry-leading heat dissipation.
ultEbase® offers better performance and environmental safety than PAOs, and PAGs. It’s formulated for precision applications, long-term reliability, and reduced power consumption under extreme mechanical stress. Proudly manufactured in the USA by SantoLubes®, an ISO 9001:2015 certified company with Six Sigma expertise and a global footprint in high-performance lubrication.
Why ultEbase® Delivers Superior Results
ultEbase® redefines expectations across a range of performance metrics – from energy efficiency and mechanical protection to cleanliness and biodegradability.

Performance Superiority Across Base Oil Classes
Lower friction. Higher efficiency. Validated results.
Not all synthetics are created equal. The performance of base oils can vary significantly based on their molecular structure, processing method, and raw material origin. ultEbase sets a new benchmark in base oil performance, outperforming mineral oils, PAOs, PAGs, and other synthetics in key functional areas:
Friction reduction
Up to 33% lower elastohydrodynamic (EHD) shear strength compared to PAOs and PAGs, translating into higher torque transfer and reduced energy loss
Thermal conductivity
Up to 15% better heat dissipation than PAGs, and significantly higher than PAOs or mineral oils, resulting in lower operating temperatures and longer oil life
Shear stability
Maintains viscosity and protective film under severe mechanical stress, ensuring consistent protection and efficiency
Where ultEbase® Excels
ultEbase® is designed for high-performance industrial, transportation, and renewable systems. Its performance and environmental profile make it ideal for:
Gearboxes
Reduces friction and power loss; increases torque throughput and oil life in chassis.
ultEbase® provides consistent film strength under demanding load and temperature conditions often seen in enclosed gear systems. Its low EHD shear characteristics support efficient torque transfer and reduced internal friction, contributing to longer service intervals. Unlike conventional fluids that may degrade or shear in high-stress conditions, ultEbase® maintains viscosity stability, helping reduce operating temperatures, wear, and unplanned maintenance.
Wind Turbines
Decreases flushing intervals and wear under variable torque.
ultEbase® performs beyond the limitations of traditional PAOs and PAGs by maintaining stable film strength under extreme loads and temperatures. Its ultra-low EHD shear strength enables smoother gear interaction and less mechanical resistance, which translates to higher efficiency and reduced internal wear. Where conventional synthetics often break down or shear under high stress, ultEbase® holds its structure, lowering operating temperatures and extending service life. This results in longer intervals between oil changes, less component fatigue, and reliable performance in both high-torque and sealed gear applications.
Electric Vehicle Drivetrains
Reduces drivetrain heat and mechanical loss; extends battery life and system durability.
EV platforms place unique demands on drivetrain fluids due to high RPMs, regenerative braking, and compact mechanical designs. ultEbase® helps reduce mechanical drag by maintaining low internal shear and resisting thermal breakdown. This supports energy transfer and temperature control, which may contribute to preserving component integrity and improving drivetrain efficiency over time. Its stable fluid characteristics align with the precision needs of electrified mobility systems.
Oven Chains
High flash points, low volatility, and thermo-oxidative stability for minimal lubricant loss.
In high-temperature chain applications, such as baking ovens or curing lines, ultEbase® maintains film strength while resisting oxidation and carbon formation. Its elevated flash point allow for consistent lubrication with reduced smoke or residue, even during continuous exposure to elevated temperatures. This supports cleaner operation, longer relube intervals, and less buildup on surfaces prone to thermal stress.
marine
Protects gear systems while meeting environmental compliance for biodegradability.
ultEbase® combines strong mechanical performance with environmental compatibility, making it suitable for marine propulsion systems, winches, and auxiliary gearboxes operating in or near water. It supports gear protection under load while helping meet biodegradability expectations. Its low-toxicity formulation reduces risk in case of fluid leakage and aligns with compliance needs in environmentally sensitive marine zones, including ports and inland waterways.
Compressors and Hydraulics
Outstanding air release, rust resistance, and foam control.
In hydraulic and compressor applications, where fluid integrity and contaminant control are essential, ultEbase® provides stable viscosity and consistent performance under variable loads and pressures. It offers effective foam suppression, air release, and corrosion protection, helping to prevent cavitation, pressure loss, and premature wear. The fluid’s clean-operating characteristics support efficient power transmission and extended system uptime in both mobile and stationary equipment.
Greases and Chain Lubes
Compatible for blending with H-1x packages; supports low-wear and high-load performance.
ultEbase® serves as a high-performance base fluid for grease and lubricant formulations requiring load-carrying capacity and thermal stability. Its chemical structure supports low wear under boundary conditions and strong compatibility with thickening agents and additive systems, including food-grade packages. This enables formulators to meet demanding performance needs across industrial, transport, and regulated environments where lubrication reliability is essential.
Elevator and Heavy Equipment Systems
Supports high-duty cycles with thermal stability and metal surface protection.
Heavy-duty equipment and vertical transport systems operate under high mechanical stress, often with limited cooling and exposure to dirt or water. ultEbase® supports thermal stability and film retention under full-load conditions, helping protect metal surfaces from scoring, and fatigue. Its ability to perform under both high-load and high-cycle environments makes it suitable for construction equipment, freight elevators, and other mission-critical lifting systems.
