Hey everyone,
I wanted to start a thread comparing Mobil 1 ESP 0W-30 and Mobil 1 FS Euro 0W-40, not tied to any specific vehicle, but more from a general performance and durability standpoint.
From what I understand, Mobil 1 ESP 0w30 has a relatively high HTHS for its grade and is known to be shear-stable, so it’s not necessarily “too thin” like some might assume. On the other hand, Mobil 1 0W-40 is very popular, especially among those who track their cars or drive more aggressively.
I’m trying to decide between the two. I realize “better” or “more stout” is subjective—especially for someone like me who sticks to 5k mile oil change intervals. Both are great oils—but is there a simple way to differentiate their ideal use cases?
For example:
Also, there’s a huge group of enthusiasts who drive their cars hard on the street (spirited driving, highway pulls, etc.) but don’t actually take them to the track. Would the HTHS of Mobil 1 ESP 0w30 still be considered more than adequate for that kind of use?
That said, I don’t think Mobil 1 ESP 0w30 is incapable of handling track duty either—it seems to be a strong, well-formulated oil. Just curious how others make the call between these two.

For example:
- If you’re tracking or racing, go with 0W-40 for the added HTHS cushion?
- If you're not pushing the car to that extreme, is Mobil 1 ESP 0w30 more than enough?
