Question : I HAVE been using my new Proton Saga (M) since last August.
The free servicing at 1,000km was done at a Proton authorised service
station in Kuala Terengganu.
In addition to other things, the gear oil was changed and a big amount of money was charged.
I would like to know whether the gear oil for this car should be changed at 1,000km.
Should the gear oil also be changed during the 5,000km and
10,000km service intervals?
Most vehicle manufacturers require that all oils be replaced at the first service.
The reason is that all the mechanical parts are new and are bedding in
(i.e. being subjected to some degree of wear as they work initially against each other).
At the 1,000km oil change, most of the bedding in process would have been done and the contaminated oil should be replaced.
After this service, the oil change intervals can be anything from 5,000km to 20,000km, depending on the manufacturer.
