My Ferrari Dino has been driven 266 miles in the last 2.5 years since the last change using Mobil 1 15W-50. Here's the result of the current analysis by Blackstone Labs:
TBN 11.0, AL 1, CHROMIUM 0, IRON 3, COPPER 4, LEAD 2,TIN 0, NICKEL 0, SILVER 0, TITANIUM 0, MANGANESE 1, POTASSIUM 2, SODIUM 5, MAGNESIUM 18, MOLY 55, BORON 130, SILICON 31, CALCIUM 2876, PHOSPHORUS 1042, ZINC 1254, SUS VISC @ 210F 78.9, FLASHPOINT 370, FUEL 0.5, WATER 0, ANTIFREEZE 0, INSOLUBLES 0.2
In their written comments Blackstone mentions the silicon as being a possible issue. At some time during this fill I noted the nuts sealing the air filter were a bit loose and I snugged them. At the last analysis at 173 miles in 2/05 SILICON was 21. Blackstone says it doubts it represents abrasive dirt as the other findings don't support that.
Is the silicon high enough that the oil needs to be changed?
Thanks
