Blackstone Comments: Wear metals still looked good in the third sample from your Toyota V-6. Everything read close to universal averages (which are based on a 4500-mile oil run)for this type engine. Insolubles (oil oxidation due to heat, use and blow-by) were low at 0.2%, showing good oil filtration and complete combustion. Silicon was okay at 14 ppm showing adequate air filtration. No gas, water or anti-freeze was present in the oil and the viscosity was good. The TBN was 3.9, still active additive left. 1.0 is too low. Nice Toyota! Try 6000 miles for next oil change.
My Comments: All the wear metals dropped except for iron. I was hoping the silicon would continue to trend downward. Oh well. It's still reading at the same level as the universal average for this engine. Plenty of life left. I'll be ready to start extending my intervals around this time next year (warranty). I was happier with the results from the K&N oil filter. Lower insolubles than the Amsoil EaO I used last OCI.
Current fill is GC Green, oversized K&N oil filter. I am using FP3000. No LC this time.
