Updated extended drain test with LC/FP/GC, same oil filter as last run. Additional 10 ounces LC. FP intermittantly ( daughter is gone too much for me to get to the car consistantly). Approximatly 30,000 miles on factory rebuilt engine. 99774 miles on car, 15,056 miles on GC oil and M1 oil filter. Oil top up total 1.25 qts over 15K miles. Oil in use a little over 12 months.

soot/solids 0, none oh yeah !!
oxidation 41.5% normal to low for duration
nitration 74% varnishing without LC to control see vis increase, additional and consistant FP60 would really help here.
sulfur oil and fuel adds
water negative
coolant negative but I am watching it.
fuel none, perfect
V100 14 cSt to darn thick for me but not far from the 12 cSt starting vis.
TBN 6.5 considering duration this is exceptionally good
Oil was changed and back on GC 0w-30 and LC for a steady diet. No apparant coolant loss but that is being monitored considering the K and Pb traces.
Runs like a top !
