That Quaker State looks strong in virgin form at least.

Quaker State wins the volatility test over them all. Look at how much more magnesium is in Castrol Edge. Double the amount or more in all the others.
That QSUD looks outstanding.

Quaker State volatility is outstanding! I'd use any of these oils but throwing in current price and the fact that i don't go past 5k miles...
1. Quaker State, 2. SuperTech, 3. Valvoline.
But if you're all about TBN, Castrol Edge looks stellar.

Price point and specs makes QSUD the clear winner. No problems with the others, but I know what's going in the Kia's crankcase next...
QSUD? Wouldathunkit?
TBN...Calcium registers as part of the TBN, so with the new formulations with reduced Calcium, it only makes sense for the TBN to dip in virgin samples.
The days of high calcium and no magnesium oils appear gone. And even Valvoline has ditched the sodium to go to magnesium. If you want high Calcium and no magnesium (like Pennzoil and QS used to be), some of the 40 and 50 grades may still give it to you.
All of these oils are great. There has never been a greater time when maintream/non-boutique oils perform so well.
*I think the higher TBN of the Castrol oil is a result of them using the opposite ratio of Mg/Ca as Mobil 1 is using. I just noticed that.

The scale for cold cranking should be the same for all. Valvoline, Motorcraft, & SuperTech starts at 4,000 but others start at 0.
Just curious, the Kendall GT-1 Max 5W30 I use is rated at 4900 Cold Cranking Viscosity, cP. Is that good?

These are the "best selling" oils or the most recent ones they tested? Just curious because did not see the ranking.
Those numbers can't be right on the QSUD, can they? Moly that high and test number that good?
The QS additive package looks very similar to regular M1 5w20 D1G2.
