Speaking of "specs", as in Performance Test Specs, the only real increment upward from PPPP 0w20 is a VW 508, LL-14FE+, or MB 229.71 oil. They have a tougher test set to pass than PPPP's dexos1.
I do like your choice of PPPP pao-like GTL Group3+ base juice, no doubt, yet it's hard to ignore those new tough German test specs.
That said, I wonder if the extended performance dexos1 oils (M1 EP&AP, Castrol Edge gold jug) can come very close to being an MB 229.71 oil.
One example:

For example dexos1 soot thickening is on the center (0?) and the other is at 7.
Does this mean there is no soot thickening with d1?
Also d1 beats the other oil/spec in every aspect ??? Is that correct? Typically that raises a red flag for me. But I am more curious as to what the numbers mean.
Thank you.
It's Lubrizol's way of communicating how tough individual performance aspects of an oil spec ask for.
Higher numbers are better on the spider chart.
Zero means there is no test for that specific performance item, as in, dexos1 has no soot test, so it gets a zero for that, meaning the oil doesn't have to demonstrate soot thickening performance.
Thanks for explaining it!
I now understand why you say that MB229.71 has a tougher test to pass. based on this spider, d1 specs looks like a joke.
There is no soot performance test in d1? I thought dexos was all about di engines?
Also why not adopt the same and existing performance specs and not reinvent the wheel? Maybe it has to do with royalties ...
Are there more legs to that spider where dexos may shine? d1 seems pretty weak compared to MB229!
