These are due to the Metal Inhibitor and Anti-Corrosion chemistry that is part of the Additive (PI) package.



Everything has a purpose.

Darn it I just ordered this but I’m guessing this is the older formula?


It could be an old picture. The label changed with the new formula. On the 5qt jugs there is a "GDI TURBO FORMULA" logo, plus it says Dexos 1 Gen 2 on it. On the back it talks about SN Plus. Those three things will show you that you have the new formula.

Just have to wait and see what you get.. Let us know!
 
I really like the performance of this newer Magnatec 5W-30 as a summer oil in my 4-cyl DI Chevy engine. Winter not so much... too thick in the "below zero" temperature range.
Winter oils will remain SOPUS' QSUD or PP. Coming in third would be vanilla M1. All three do well down into the -20 to -30 deg F range.

Zinc is a bit lower at ~ 700 ppm (your GTX UltraClean was ~ 800 ppm), but I assume the Titanium is doing the heavy lifting here, which the GTX didn't have.

Nice LSPI friendly detergent pack of both Ca (~ 1060) & Mg ( 715 ppm) in the Magnatec. The GTX UltraClean was all Calcium (2574 ppm)
Good to compare the two (GTX UOA Link)

Thanks for the VOA


I'm guesstimating that the moly, boron and possibly esters are making up for lower zinc ppm.
 
Here is a link to a UOA of Castrol Magnatec 5W20 Dexos1-Gen2 from member ARCOgraphite in December 2019 from a 2017 Subaru Crosstrek with (60,864mi)

VOA (2018) / UOA (2019)
5W30 / 5W20
D1G2 / D1G2
Moly 60 / 55 (ppm)
Ti 30 / 24
Boron 200 / 55
Si 7 / 14
Fe 2 / 5
Zn 695 / 673
Ca 1063 / 1028
Mg 715 / 689 (ppm)
TBN 7.1 / 2.9
Miles 0 / 8199

Apart from the Boron, which I hear is the only element that significantly depletes from VOA to UOA (don't know why), this looks like the same add pack to me.

It did a good job.

This VOA is sooooo close to the Valvoline Synthetic VOA that's it's a toss up. Going to come down to the $ of each bottle. I'd run either with confidence.

Good looking add pack on both the Magnatec and the Valvoline Syn.
