Hey everyone,
I wanted to start a thread comparing Mobil 1 ESP 0W-30 and Mobil 1 Euro/FS 0W-40, not tied to any specific vehicle, but more from a general performance and durability standpoint.
From what I understand, M1 ESP 0W-30 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, M1 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 ESP 0W-30 still be considered more than adequate for that kind of use?
That said, I don’t think ESP 0W-30 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 ESP 0W-30 more than enough?
