PETRONAS Tutela AS8 is a fully synthetic Automatic Transmission Fluid (ATF) that delivers long-lasting shifting performance and component durability over the entire service life of the transmission. It is approved and recommended by Stellantis (former Fiat/FCA) for 8- and 9-speed step-type ZF automatic transmissions fitted to passenger cars. The friction behaviour of the fluid has been optimally adapted to these transmissions, providing perfect shifting characteristics and vibration-free operation, while its optimised viscosity helps reduce fuel consumption. With a kinematic viscosity of 5.6 mm²/s at 100°C, a Brookfield viscosity of 8850 mPa.s at -40°C and a pour point of -42°C, it stays fluid in cold conditions and protects across a wide temperature range. Approvals: FIAT 9.55550-AV5 Contractual Technical Reference N°F139.I11, MS-90030-A5 and ZF TE-ML 11. Always consult the owner’s manual to check the recommended specification for your specific vehicle.
