The tests in black are the only ones with limits and in that case Castrol Edge are not banging up against them.
You recently posted that you can't always link to facts because there isn't always time.
The truth is somewhat different. You read too fast, lack analytical rigor, indeed basic comprehension of tables with numbers in them, and then say what you want to believe anyway.
In this instance, where you've commented on something we can all see, your lack of analytical ability and the fact that you say what you want to believe is apparent to everyone.
Re how Castrol performs in the tests with limits:
V 100c - 2 oils are higher, 4 are lower. But which end is desirable is debatable. What is not debatable is that Castrol is not banging up against any limit on this one.
V -30c - Castrol has the highest of the 7. Lower is better in this test!
Noack - 4 of the 6 competitors are far far better. Only 2 are worse and not that much worse.
Phosphorous. Castrol is average in the range.
So NO WAY is Castrol banging at the better end of any limit.
Now onto tests with competitive ranges:
Castrol has lowest VI (and one of the worst NOACK - what does that tell you about base stock quality?)
Highest V at 40c
Second highest Moly which you said is bad and that the best oil manufacturers were putting at zero. Btw that means only Valvoline meets your criteria
The most aluminium contamination and therefore most contamination overall
Middle of the range boron
Average in all other additives except:
Lowest calcium and highest magnesium
Lower than average phosphorous and zinc
Out of 28 tests, Castrol leads in 1 - TBN and chooses to have the lowest calcium and highest magnesium
Your statement that I quoted at the top of this post is so far away from the truth that your credibility can be added to those things at the bottom of the range.
