Valvoline White Bottle 9.8 TBN after use?!
Is the TBN of VWB even that high when new???
Thanks ZZman and/or to whoever put the work in on the chart. It at least gives you an idea of the additive pack of the lubes and that in itself is a nice reference.
I probably should have left the used TBN numbers off the chart as there are too many variables and no info to compare it too.
All these numbers were pulled from VOA's and UOA's from this site.
I agree the VWB is not correct.

Nice work.
I used VWB for years, but was told that QSGB specs were better. Did VWB change the formula? What's up?
WOW! Havoline shows no MOLY and at onetime they were KING! Like 300-400 ppm of MOLY. It's too bad as I have a boat load of Havoline 5W20/5W30 in my stash.

The blackstone report that showed havoline had no moly was wrong, even the PQIA site shows it has ~70ppm

My Havoline is all SN/GF-5
I like Pennzoil conventional and Valvoline Conventional.
Whats the difference between the SN spec and the SM spec? Which is better? What does SN and SM stand for? Thanks.

You should include sodium (Na) on the chart. Many oils with relatively low calcium levels use a calcium/sodium detergent package and also have 400-500 ppms of sodium.
