ATF-A7 is an extremely low viscosity formulation with low friction to achieve best-in-class fuel economy and driving performance. For easy identification, ATF-A7 is colored Red and ATF-FZ is colored Blue. ATF-A7 includes UV-reactive dye (see \"Fluorescence Example\" below). There is NO interchangeability between ATF-A7 and ATF-FZ. For CX-30, Mazda3, and CX-5, some 2.5L and all 2.5T engines still use ATF-FZ. Verify the type of ATF according to what is in MGSS (TRANSMISSION/TRANSAXLE TECHNICAL DATA) or what is marked on the dipstick (see \"ATF-A7 Identification\" below).","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11026348-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11026348-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11026348","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-30","year_from":2023,"year_to":2026,"match":"exact","vehicle_ids":["2023_mazda_cx-30","2024_mazda_cx-30","2025_mazda_cx-30","2026_mazda_cx-30"]},{"make":"MAZDA","model":"CX-5","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_mazda_cx-5","2025_mazda_cx-5","2026_mazda_cx-5"]},{"make":"MAZDA","model":"CX-70","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_mazda_cx-70","2026_mazda_cx-70"]},{"make":"MAZDA","model":"CX-90","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_mazda_cx-90","2025_mazda_cx-90","2026_mazda_cx-90"]},{"make":"MAZDA","model":"MAZDA3","year_from":2023,"year_to":2026,"match":"exact","vehicle_ids":["2023_mazda_mazda3","2024_mazda_mazda3","2025_mazda_mazda3","2026_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
