Looks like a new updated formula of the Mobil 1 ESP X3, but in same ways a worse oil:
It's interesting, it might be a rebanding of an updated formula the current Mobil 1 ESP X3 C40. Both oils are HTHS of 3.8, but as noted the viscocity index of 40 GT is lower at 199 vs 204 for Mobil 1 ESP X3.
Generally, this new 40 GT oil, unless it has a ton of ZDDP additives and moly, on paper does not look impressive or much different than Mobil 1 ESP X3.
It's rare you see a Mobil listing specific brand applications, but at the same time saying it's not approved.
"Mobil 1 C40 GT 0W-40 is not suitable for Porsche vehicles requiring an A40, C20, C30 or C40 approved Mobil 1 engine oils."
Anyone hear anything?
