synthetic fluids & lubricant basestocks
Synthetic basestocks for automotive gear oils


Gear oils formulated with synthetic lubricant basestocks offer higher resistance to breakdown from heat and high-speed operation. They help protect and extend the life of automotive gears, rear axles and differentials. They typically exceed the most severe requirements of most automotive and truck rear axles.
Our synthetic lubricant basestocks are used to formulate gear oils that offer:
- Better oxidative and thermal stability for long service life
- Lower pour points for improved operational low temperatures
- Cleaner equipment, less varnish and sludge
- Improved fuel efficiency
- Less in-shop downtime
- Less oil disposal
See our Synthetic Basestocks Formulations Guide for specific basestock recommendations for developing various synthetic gear oil grades.
