Here the service requirements are 6 months. I reckon 12 months or 16000 miles is a long time between new oil in a diesel. I also think that the tin tent might have an effect. If it was mine, I would be booking it in for some nice new oil and a check up. Gone - 2008 Stornoway Grey RRS 2.7 TDV6

I guess the environment there is harsher so 6 monthly checks are recommended - they are here if you go off road regularly, etc. 1000 miles towing on mainly motorways and 8000 solo in 10 months doesn't appear to be a hard life to me for a vehicle built to go anywhere on the plant and survive  Wanted a Series 2 LR since childhood but previously owned MY16 Disco Sport HSE TD4 Auto, MY13 RR Sport Black Edition TDV6 Auto, MY10 RR Sport HSE TDV6 Auto, 2007 Freelander 1 Freestyle TD4 Soft Top, 2009 Freelander 2 GS TD4 Auto, 2007 Freelander 2 GS TD4, 2004 Disco 2 Metropolis Auto, 2002 Disco 2 GS, 2000 Freelander 1 SE TD4 SW

Still hoping for a S2 one day!

The MY10 I had before always went 12 months and my driving patterns have not changed - maybe they've found another way to boost profits  Wanted a Series 2 LR since childhood but previously owned MY16 Disco Sport HSE TD4 Auto, MY13 RR Sport Black Edition TDV6 Auto, MY10 RR Sport HSE TDV6 Auto, 2007 Freelander 1 Freestyle TD4 Soft Top, 2009 Freelander 2 GS TD4 Auto, 2007 Freelander 2 GS TD4, 2004 Disco 2 Metropolis Auto, 2002 Disco 2 GS, 2000 Freelander 1 SE TD4 SW
