Cat oils are a part of the full system design of the machine, as an original genuine part with the following principles:
- Exclusive formulation with rigorous proprietary Caterpillar testing
- Base oils and additives selected exclusively for Caterpillar
- Cat DEO™
- Cat DEO-ULS™
- Cat DEO™ Cold Weather
Combine Cat fluids with Cat filters for the highest level of contamination control – proven to extend the life of your engine.



Get oil that works as hard as you do. Even after exceeding industry specifications, Cat drivetrain oil is run through five quality tests and thousands of hours in the field. Formulated to meet the most stringent standards, it’s the best fluid protection for any drivetrain.

Severe Caterpillar internal test designed to simulate slipper socket wear seen in the field:
- Charge Oil Temperature – 100°C/Loop, Oil Temperature – 130°C
- 380 bars, 2200 RPM

The test with SAE 10W was terminated at 178 hours due to catastrophic failure caused by the slipper wear.
At 200 hours, the additive package of Cat HYDO Advanced 10 prevented the slipper socket wear observed with SAE 10W.
