so based on the number of samples tested on a particular oil and number of TBN and if changing oil every 3000K..the mobil 1 5W-30W is the best for 350Z then since it's TBN is relatively high for the number of sample that were tested? is the mobil1 5W-30W a synthetic oil or conventional oil that was tested?

castrol syntec >> mobil 1 v.withUOA
same exact driving conditions, driving to and from work about 20 miles each way, 15 of that highway driving. and a lot of city driving on the weekends. redline it probably every few days.
castrol syntec is the report of the left and mobil is the report on the right
the syntec was run for 5200 miles and the mobil 1 only 3750.
i don't think i'll ever be using m1 again.

The TBN is getting low. I only have one other UOA on this oil form the DE engine, so it's hard to say where you might want to draw the oil change line. Give the 7500 mile OCI a shot if you want, and if you get a TBN, you'll know where the oil change limit is with this oil. I think 7500 miles will be about all you'd want to do with this oil in the DE.
Yeah, M1 5W-30 and 10W-30 haven't been anything impressive, especially for the cost. The Syntec weights have all looked much better in the VQ. However, one formula isn't indicative of the blending which occurs across the whole brand. While their 5W-30 and 10W-30 isn't very appealing, there are other M1 blends which are blended very differently and perform much better in the VQ.

Valvoline SynPower 5w-30
Some low rpm detonation starting near end of this OCI (hot summer ambient temps)
4,850 miles on this stuff.
11,300 miles on revup VQ TSB replacement.
Comments welcomed.
In service now is Amsoil's ASL 5w-30.
Taking that to ~5K mile OCI as well.
Cheers
