excuse me, could not figure out how to make this a nice picture!
2008 cadillac DTS, northstar v8, 51,000 miles, did 5300 miles on mobil one synthetic. blackstone labs used.
aluminum 4
iron 7
molybdenum 68
boron 39
silicon 5
calcium 1136
magnesium 666
phosphorus 689
zinc 740
sus viscosity 57
cST viscosity 9.6
fuel less than 0.5%
water zero
insolubles just a trace
TBN 2.2
now my dumb questions
they gave this a good review, and said to try 7000 miles next time.
1. what does molybdenum represent?
2.what do you experts think of a TBN of 2.2?
3. how long would you go before my next oil change?
THANK YOU!!
Bob
