其實國外論壇也有在討論。

The new products both have superior low temperature performance to the one they replaced but are, as has already been noted, lighter.
However, people need to keep in mind that the new Mobil 1 FS 0w-40 that is GTL based is actually VERY similar in viscosity to the original Mobil 1 0w-40 that was PAO-based. It was the later VISOM (and SN) version(s) that bumped up visc and HTHS.
所以即使像美孚這種老廠，也是放棄了原有的堅持，「成本」還是很重要的。
