The ESP X3 is a bit of an exception but they are Euro mid-SAPS.
Mobil 1 0W-40 Supercar vs Mobil 1 0W-40 ESP
- Thread starter RDT-G23
- Start date
That's ~3.3% and ~1.0% respectively. Is that really significant (genuine question)?
I was looking at the Lubrizol comparison tool, and while they are different specs, we can see what they require:
ESP 5W-30 and ESP X3 0W-40 both meet MB 229.52, so I put it in the middle. ESP 5W-30 meets the specs up to MB 229.52, and ESP X3 0W-40 from MB 229.52 onward in the table. C40 is stricter in SA than C30, but ESP 5W-30 already meets the stricter MB229.52 in the SA% aspect. So maybe it's something else?
Great question & I'd not have a good answer for that. It's amazing how little a formula can be but how majorly different advertising can make it sound like it's a totally different product. Sort of exactly what we see here. One is positioned for emissions while the other is not but yet there is very little difference between them.
Don't know how accurate but I just dug this one up but it's the FS

There probably will be an update to SP soon.
Supercar 0w-40 doesn't meet MB 229.52.
No, Supercar does not meet any MB specs. None. ESP X3 is probably better and does meet 51/52.
Show me where you see that?
SP adressess LSPI and timing chain wear by reducing calcium-based detergents to magnesium-based detergents ratio along with eliminating sodium-based detergents from the package. Reducing detergency of the oil is also known to reduce the competition over the metal surface in favor of making ZDDP more effective, thus, reducing wear in several key engine components using different approach. Generally SP oils are more prone to shorter life than SN+ oils but I'm not in position to empirically conclude by how much. However, since both additive packages have lowered ZDDP limits, SP is leaning to higher wear control due to the reason above.
I thought SN+ was for LSPI, and SP was for timing chain (I might be mistaken though). That being said, according to the following two VOA posts for ESP 5W-30 and ESP 0W-40, they both seem to have similar levels of Ca and Mg. I don't know if the P + Zn levels are within measurement tolerance ranges though, because they do seem a bit higher for ESP 0W-40.

The 5W-30 linked is the old SN+ formula.

That's why it's so important to feed your gasoline engine SP motor oils having higher quality base oils. Some of the oil additive counts may look anemic with Mobil-1 EP oils and Pennzoil Ultra Platinum. But don't be discouraged by it. Higher levels of Natural Gas induction base oils are at play here. We are well protected, despite the lowered oil additive numbers displayed.
Want the best of both worlds? Purchase boutique oils from the likes of HPL, Amsoil and a few others. Just be prepared to pay more for them.

Mobil PDS's royally suck these days. Somebody needs to do some VOA on the new stuff.
PDS dated July 2024 lists Calcium at 0.17 mass% per ASTM D4052 specs for the 0W-40. I think that converts to 170 ppm.
I originally thought that M1 Supercar 0W-40 was the rebranded "old" FS formula because it is not API SP rated, but noooooooooo.
The old FS Calcium was 3294 ppm. New M1 FS 0W-40 PDS has ZERO data on the ingredients.
M1 Supercar 0W-40 is super-light on Moly, Magnesium (0%), Zinc, and phosphorus. Not the same as old FS, that's for sure.
Looks like the new M1 Supercar 5W-50 is a slightly higher than 0W-40 in everything listed (which is very little actual info) except Calcium is 73ppm and gets the newer API SP rating for direct injection engines.
I've been running FS 0W-40 for years in most of my vehicles because it was supposed to contain a high PAO blend. Any recommendations of a different new oil that doesn't suck? I like high SAPS for a high mileage low reving V8 Truck.

So many here think lowered Calcium is only for the LSPI conditions.
More importantly, less Calcium produces less Carbon. Less Carbon aids in our breathing power.
LSPI concerns seems to have vanished with gasoline, grocery-getter vehicles under five years old, using PCMO / ILSAC SN PLus / SP oils.
Valvoline and Quaker State remain 1000+ Calcium oils.
Castrol, Mobil-1 and Pennzoil are all sub-1000 Calcium now. The integration of cleaner natural gas base oil have paved the way for that.

What do you think is "wrong" with FS 0W-40 currently to make it "suck"?Mobil PDS's royally suck these days. Somebody needs to do some VOA on the new stuff.
