Blackstone Laboratories Oil Analysis Reports
#301
Decided to have an analysis run before the drivetrain warranty expired. Engine was formerly sludged by the lessee. This is post cleanup, 4200mi run with Pennzoil Ultra platinum. Numbers are good. Gonna go longer next time.

I got my car at 60,000 miles, and have been using Castrol Edge Titanium 5W30
up to my last oil change at 99,000 miles. This report reflects my last oil change with an interval use of 6,300 miles.
I switched to Mobil 1 0W40 and will get another UOS on the next oil change.

My apologies, but I'm not sure how to interpret the numbers. The overall outcomes from the available data suggest what with respect to "best" oils for the 37's? Essentially:
- Which top 3 oils have the best wear numbers overall?
- Which bottom 3 oils have the worst wear numbers?

From Blackstone:
"Ok, now for the technical questions. What is a TBN?
A TBN (total base number) measures the amount of active additive left in a sample of oil. The TBN is useful for people who want to extend their oil usage far beyond the normal range.
Do I need to send in a separate sample for a TBN?
No. We can run your TBN on the same sample of engine oil you send. It's also not necessary to send in a sample of virgin oil for a TBN. You're welcome to do so, of course, and many people do this to see where the TBN starts out. If you do send in the virgin oil sample, the cost for that sample is the same as for your used engine oil sample.
The TBN is based on the level of calcium sulfinate and magnesium sulfinate in the oil..."
Why best three? Why not absolute best? Motor oil is one of those never-ending discussions, like white bread vs wheat bread or "less filling/tastes great". Pick a quality oil of the appropriate grade and change it regularly.

Blackstone results
I am trying to understand the iron level result. Does it mean anything about the engine, or the kind of driving I do?
Also, I wonder where the iron is mostly coming from- the valve train / timing chain & parts? Camshafts? Crank? Just curiosity.
Right now, my car is under CPO warranty so I am sticking to Infiniti's 7,000 miles OR 7 month oil change "rules" - but after the CPO warranty runs out, I will probably go with a 12 month oil & filter change routine, I drive less than 5,000 miles in 12 months. The oil in this analysis had lots of life left in it - lots of neutralizing ability and lubricating properties left after 7 months / less than 3,000 miles, so I am pretty sure 12 months / 5~6,000 miles will be just fine.

I can also picture how a lot of start - stop driving would put stress on all these parts that you wouldn't get with the smoother action of more constant driving.
I wonder what oil analysis results look like from guys who take their cars to the track.
