The link I posted is from 28/07/2011 which appears to supersede your April 2010 info

However for years they had the wrong size winter 19" tyres in handbooks so it's anyones guess which is right

Personally I give up  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!

sure I agree I have sent your pdf to LR for clarification, however thinking some logic A1 is a cleaner oil than C1 so if you don't have PDF A1 would make sense C1 if you have a PDF as it removes diesel particulate matter or soot from the exhaust gas of a diesel engine.

I used Castrol's oil selector tool and it recommended Magnatec 5w30 A1 for my non-DPF TDV8

2008 TDV8 - it was a labour of love and is much missed
