Rover PG1

The service manual says your Rover PG1 gearbox id filled for life, and requires no periodic renewal. However, some people choose to replace the oil in sync with their C service. Some have commented that a better oil can improve gear change and reduce noise.

Dry fill capacity = 2.4 litres, Refil = 2.1 litres


Honda M6T

The Honda gearbox is also normally considered filled for life, but the OEM gearbox oil is quite thin and some people change it for a more viscous gearbox oil to cope with high temperatures (eg. heavy track use) better.

Dry fill capacity = 1.7 litres, Refil = 1.5 litres
