JASO ATF F-1

JASO ATF F‑1 is a Japanese standard for automatic transmission fluids that defines requirements for viscosity, friction stability, oxidation resistance and wear protection when operating over a wide temperature range. The specification is aimed at wet‑clutch transmissions, including automatic gearboxes, dual‑clutch and variator systems used in motorcycles, scooters and passenger cars of Japanese manufacturers (Honda, Yamaha, Suzuki, Kawasaki). A fluid that meets JASO ATF F‑1 provides smooth gear shifts, a stable friction coefficient for clutches and high thermal stability, preventing deposit formation on internal components. It is compatible with catalysts and DPF systems because it does not contain sulfate additives that could contaminate them. When selecting on xenum.ua this mark helps technicians quickly find a transmission oil, such as XENUM XA‑TRAN DX VI, which fully complies with JASO ATF F‑1.
