This is the latest UOA from my wife's car. Here are the results from Wearcheck Canada. 8,200 miles on oil Nov 8, 2005 to Sept 23, 2006 (10.5 months) 76,000 miles on engine German Castrol Syntec 0w30 K&N oil filter Fram air filter Mostly city driving 4L oil capacity No top up oil Iron 19 Lead 6 Aluminum 4 Copper 2 Chromium 1 Nickel 0 Titanium 0 Tin 0 Silver 0 Silicon 8 Potassium 0 Sodium 1 Boron 1 Barium 0 Calcium 2847 Magnesium 132 Moly 1 Phosphorus 767 Zinc 891 Oxidation 84 Nitration 82 Sulfation 59 Fuel <2% Water 0 Glycol 0 Viscosity 12.5 cst at 100c (40wt) TBN 2.49 This is the second UOA in a row from this car that I'm disappointed with. The wear numbers have gone up the last two intervals. The TBN is a lot lower than I'm used to for GC also. I put Syntec 5w30 in there now, so I'll change it around 6 or 7k and see how it does. Perhaps this Honda just doesn't like an oil as thick as GC?
