I didn't get a TBN because I only ran it 3200 mi. No modern oil would lose its protection in that little time so I knew the TBN would be fine. When I do my first 10,000 mi interval I'll get the TBN. Blackstone is $20, plust $10 for TBN.
The silicon is high because of the freshly sand cast engine block, etc. It says I was using a Mopar filter.
Mobil 1 always has about 50 to 100 ppm of moly in it, and this had essentially none. That's why I don't believe it's Mobil 1.
Also, the calcium, magnesium, phosphorus, and zinc are not in the right ratios typical to M1.
Aah the filters I forgot about that, senior moment I guess.
I was told by engineer at Chrysler that has not been true for over two decades in the US, but maybe in Italy it still happens. Engines do have above norm metals at break in and high Si often from dust in intake parts before assembly.
You know the chemical make up of Mobil 1 0w-40? That's unusal. What do you think happened, dealer added some non Mobil 1 oil durring it's stay at the dealership?
Some modern oils can loose the TBN in 3000 miles easy, see it several times in last 3 or 4 years. All diesels by the way.
Anyway nothing harmed unless the oil is a special break in oil that's used in some European cars such as VW and MB. I could still be a special order Mobil 1 0w-40 used only for break in purposes for a set period such as 6250 to 12500 miles. VW does this and has a first oil change on their diesel at 5,000 miles, second one is another 5,000 miles then every 10,000 miles there after if proper synthetic oil is used.
