On the oil and filter change interval as stated in the manual...every 10,000km OR 6 months. This implies that both should be changed regardless of the distance covered should it be less than the stated maximum distance once a period of 6 months has elapsed.
So if the engine only covers 100km in 6 months, the oil according to Rover should be changed along with the filter.
Time it would seem carries considerable significance when it comes to the life of an engine oil.
Tank wrote,...Hello Frank,But I'm a great believer in companies like Land Rover and Shell and Caltex et al who have done millions of $ worth of research on what oils to use and what intervals that oil should be changed at.
I had a look at the Penrite website as this company is the official supplier to Land Rover within Australia.

Quoting the site....."Your owner's manual will give you information on what kind of oil you need for both normal and severe driving conditions. It might surprise you to know that a lot of driving actually falls into the severe category. Extreme temperatures, frequent short trips, stop-start traffic and hauling or towing all put extra strain on your engine and mean you need an oil that is suitable for severe driving conditions, as well as more regular oil changes.
A good guide is to change your motor oil and oil filter every 5,000 kilometres or every six months, whichever comes first. Doing this will give better engine protection and prolong your engine’s life. Make sure you check your owner's manual for special conditions and do not exceed warranty recommendations".
I did not tend to follow the 6 month guide with my 3.5 litre engine, so no doubt that contributed to additional wear. With my new 4.6 I am changing the oil within time periods not exceeding 6 months.
