Reading that service schedule says to me in the UK with std low sulphre diesel the oil changes are indeed every 15k or annually, ie a std A service and the B service is just another A with extras.

Its only when abroad using lower spec diesel that the oil change intervals need to be shortened.
Im not sure what sulphur percentage UK diesel has? but as Euro4 came out in 2006 I would say its way way lower than the numbers you quoted from the LR service schedule.

Hi

Out of interest I had a quick look, indeed as u say that service sheet is a uk spec

European UnionEdit
In the European Union, the “Euro IV” standard has applied since 2005, which specifies a maximum of 50 ppm of sulfur in diesel fuel for most highway vehicles;[19] ultra-low-sulfur diesel with a maximum of 10 ppm of sulfur must “be available” from 2005 and was widely available as of 2008. In 2009, the Euro V fuel standard came into effect [20] which reduced maximum sulfur to 10 ppm. In 2009, diesel fuel for most non-highway applications is also expected to conform to the Euro V standard for fuel. Various exceptions exist for certain uses and applications, most of which are being phased out over a period of several years. In particular, the so-called EU accession countries (primarily in Eastern Europe), have been granted certain temporary exemptions to allow for transition.

Certain EU countries may apply higher standards or require faster transition.[21] For example, Germany implemented a tax incentive of per litre of "sulfur free" fuel (both gasoline and diesel) containing less than 10 ppm beginning in January 2003 and average sulfur content was estimated in 2006 to be 3-5 ppm. Similar measures have been enacted in most of the Nordic countries, Benelux, Ireland and the United Kingdom to encourage early adoption of the 50 ppm and 10 ppm fuel standards.[22]

Indeed , like ur goodself , won’t allow it to go past 5k , last engine oil change and filter was 6 x litres , that was at 1500 miles but as 12 x months has expired since doing the last service I changed it anyway

Maybe it’s an overkill but Would rather spend a few hundred quid looking after it the best I can
