Here are the first results from my Tacoma. A bit concerned abut the copper number even though it says I shouldn't be...what does everyone here think?
Code:
Comments from Blackstone: Everything looks normal for an engine with less
than 15,000 miles on the odometer in this first sample from your Tacoma.
Universal averages show typical wear for Toyota's 4.0L V6 after about 5,400
miles on the oil. You ran just 4,863 miles, and the extra copper is from
wear-in of brass/bronze parts, while silicon is from harmless silicone
sealers that are still washing out of the block. The viscosity was a touch low
but that's not an issue. The TBN was 2.6, plenty of active additive remaining
in the oil. A TBN is too low at 1.0. Try 5,500 miles next and then check back.
