Editing Gearbox oil

== 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.

PG1 needs API GL4 spec for the synchros.

Dry fill capacity = 2.4 litres<br>

Refil = 2.1 litres

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<br>
Refil = 1.5 litres
