Hi All,
This is a summary of the Blackstones report on my last oil change after 10,000 km on Liqui Moly 5/40 Synthoil High Tech. The V40 1.9 turbo diesel is the same basic block as the Renault Laguna 1.9D, so they gave me those averages to compare with and the engine has 180,000 km total.
Oil added: Nil (Used about 0.3 ltr)
Aluminium 5 (Average from Renault diesel 8)
Iron 24 (46)
Copper 5 (5)
Lead 2 (5)
Tin 2 (5)
Viscosity 210F 67.9 (Should be 66 to 78)
Viscosity 100C 12.4 (SB 11.9 to 15.3)
Fuel less than 0.5% (SB less than 2)
Antifreeze and water nil
Insolubles 0.4% (SB less than 0.8)
TBN 4.7
In general the wear metals were half of the Renault figures and the TBN plus insolubles indicate the oil would be good for a longer service interval, which surprised me because we have had a very cold winter and my car does a horrific amount of stop go driving.
I am sticking to doing the oil and filter changes every 10,000km but will try the slightly cheaper LM diesel synthoil 5/40 next to see how it compares.
I only use Liqui Moly oils at present although that is partly because they are good value for money in Germany.
