What brand of transmission oil is suitable for the Q5?

Audi Q5 is equipped with an S-Tronic dual-clutch transmission. Here is an introduction to dual-clutch transmissions: 1. In a dual-clutch transmission, one clutch controls the odd-numbered gears while the other controls the even-numbered gears, enabling extremely fast gear shifts. 2. The structure of a dual-clutch transmission is quite similar to a manual transmission, with the main difference being an additional set of clutch and gear shift control mechanisms. 3. The production and development costs of dual-clutch transmissions are relatively low. 4. There are two types of dual-clutch transmissions: dry and wet. In a dry dual-clutch transmission, the clutch plates are not immersed in transmission fluid.
I've been driving an Audi Q5 for several years and have some insights on transmission fluid. The brand of transmission fluid depends on the vehicle model. For my automatic transmission car with a ZF gearbox, the manufacturer recommends Audi-specific fluid or ZF Lifeguard. However, I've also tried compatible brands like Castrol Transmax ATF and Fuchs, which worked quite well and might be more cost-effective. The key is to match the right product; using incorrect fluid can damage the transmission. I always check the manual to confirm specifications, usually requiring JWS standard compliance. The fluid change interval is typically every 60,000 kilometers, ensuring smooth shifting without wasting money. If you opt for cheap alternatives, over time the transmission may develop noise or slippage, and repairs would cost far more than the fluid. Choosing reputable brands is always the safer choice - safety first.
Having worked on car repairs for so long, I've dealt with numerous Q5 transmission issues. Brand selection depends on the specific model: for older models with automatic transmissions, I recommend ZF Lifeguard or Audi genuine oil; newer models have better compatibility and can use Mobil ATF or Pentosin, but you must check the specifications to avoid mistakes. Genuine oil is more expensive, while aftermarket brands save about 30%. I've found that regular oil and filter changes every 60,000 km are crucial—otherwise, degraded oil leads to poor power transfer. I advise owners to bring their manuals to the shop for confirmation; using the wrong oil may damage shift components, which isn't worth the risk. High-quality oil ensures quieter operation and longer transmission lifespan.
