Its anti-wear and anti-foam lubricating properties protect metal components and ensure smooth gear changes.

On the other hand, an automatic gearbox requires a special fluid called "automatic transmission oil". This fluid is lighter and has different properties. It acts not only as a lubricant, but also as a hydraulic fluid to operate the gearbox's clutches and brakes. hydraulic fluid to operate the gearbox's clutches and brakes.
