Hi there and welcome.
I would find that mis-match of information confusing also.
However, I would suggest having a trawl through this forum for
failure, and a common theme will arise - the servicing intervals that Renault originally suggested was way too optimistic, and seems directly related to major engine problems. When a
's seals go, it isn't always just a case of fitting a new one, sometimes the
starts ingesting the engine's
(dumping it out of the exhaust), and going into 'runaway mode' - whereby the revs soar, and unless you switch off/stall the engine in time, it'll run out of
, and sieze solid.
This isn't just true in Australia, but everywhere else - Renault have reduced the service intervals back to a more sensible level, in the face of many warranty claims & goodwill payments.
You can never come to harm servicing a car too frequently, but it is a risky game to play (with little to gain, and much to lose), by exceeding intervals.
