Cat FDAO SYN is developed, tested, and approved by Caterpillar to meet the same rigorous standards as Genuine Cat Parts, delivering exceptional performance and reliability. This advanced synthetic formulation is engineered to extend drain intervals by up to three times compared to Cat TDTO™ and TO-4 oils—reducing downtime and maintenance costs. Its low-foaming properties help protect against the damaging effects of air, while its superior wear protection has demonstrated the ability to double bearing life and quadruple gear life in demanding off-highway applications.
