Manual
just oil in most cases
The oil type that is used for a manual transmission will depend on the car. Most cars will take 10W30 oil.
The manual says 80W90 gear oil, which is kind of odd considering most aluminum case manual transmission use ATF or a light weight motor oil.
Most likely the ax15 manual transmission
Most cars this is not a problem, the engines are identical.
