For a while I had considered a 0w-30 instead of 0w-20 in my vehicles. I even found Mobil 1 ESP 0w-30 for less than $7/qt online. But when I compared the two, it appears Mobil 1 ESP X2 0w-20 may actually be a bit more robust. Not sure if this would apply to all VW oils specified as 504/507 and 508/509, but here is what I gathered from the product spec sheets for the two M1 products.
Grade_______________________________ Phosphorus________Zinc_________HTHS_________ASH__________TBN
Mobil1 ESP X2 0w20 VW 508/509_______ 880____________950___________2.6___________ .8___________ 12.1
Mobil 1 ESP 0w-30 VW504/507__________800____________ 900__________ 3.5___________ .8____________ 7.6
The TBN for the 0w-20 is from a VOA by Blackstone I found here at BITOG. Mobil 1 ESP X2 0W20 VOA (BITOG) It seems to be too high, but who knows. The HTHS viscosity of the 0w-20 may be an issue for some.
All things considered, I'll probably stick with the 0w-20, although the 0w-30 would probably be fine too. Given a choice for a 2020 VW 1.4 Tsi, what would you run?
