Good score. I had not run across that pricing. The Mobil 1 fs x2 5 50 is a tiny bit cheaper than the supercar and also sp grade.
Im sure you remembered when filling, but these Castrol bottles are quarts and not liters. I messed that up and got a low oil light pretty quickly. First time for everything.
In terms of the mobil supercar vs x2, the x2 is more appropriate I believe.

VISCOSITY... as essential factor
What is positively affected is the hydraulic mapped VVT positioning.
With MOD-0 and stock viscosity, when the piston squirters begin to open, it royally screws up VVT positioning that silently confuses the ECU without code - This is the cause for laggy fuel map.
With better oiling this pressure transition happens right outside idle Rpm before engine develops power. So that ECU never sees VVT positioning jumps.
In addition the oil temperature being controlled without heatsoak preserves the working viscosity such that runtime hot engine VVT map remains valid.
(Smart TCU uses multiple ATF temperature maps *BUT* the kludgy VVT does not).
Meaning... better oiling cancels the engine runtime moody weaknesses caused viscosity variations. This is a big deal because extreme heat corrupts maps as it affects runtime. The ECU has limited ability to work with wildly variable viscosity.
The engine operation can/should remain precise without extreme heat impacting viscosity and fixed-map computations (**).
The key contribution has been to identify factors that help the engine retain predictable smooth timings ie. performance.
Poor oiling DeTUNES engine output. Many times I've experimentally found & confirmed:
"MOD performance is based on the oil being used".
Ppl on MOD-1 are stuck in "preview mode" without much driveability improvement.
> Top Limiting Factors Involved :
- runtime viscosity
- stored core heat
- VVT Mapped position x4
- rings blow-by losses
- CAN-C bandwidth
- ECU+TCU fixed-map computations
> ECU + TCU Mgt Team:
-- The ECU/TCU respond well to experimental improvements.
-- Our engine computers are unmatched for stock oiling.
-- Limited engine driveability under 2500.Rpm is squarely pinned onto oiling condition.
Using an hybrid electric engine and turbo to make up for limited oiling is amazin solution for missing torque.
(**) the single target of engine mgt is optimal computation of mechanical variables.
Deutch pragmatism dictates to optimize factors under control.
Give it oil.

MOB1 5W50 SELECTION
Both are excellent high quality oils with high flash temps (400/430F) for less impact on viscosity variations.
Given the choice, I'd pick the right side oil for its cleaner formulation with less zinc contaminants.
Left side oil has higher protection package for higher output applications.
The flip side is higher deposits... necessary for protection!
High power output needs proven solid anti-friction besides a viscous film. This has not changed!
Thin lubricants with clean-lean formulation wear out engines more rapidly.
Mixed city driveability: right side oil
Spirited power protection: Left side oil.

RACING APPLICAT°
@CaliBenzDriver would you say 700+ horsepower m157 motors Qualify for left side oil over right side?
that would be left side : "MOBIL1 Supercar" with additional friction modifiers - Viscosity alone can not protect high output engines nor trannies.
That's when ZDDP steps in and Lambda/cats are replaced by mapped fuel. MOTUL has a ZDDP RACING oil.
This must be a true blast to handle!

thank you for the great info! Really tough choice between M1 Supercar versus Motul 8100

sorry, I couldn't open them either. I was going off of the mobil website, which has changed a bit since they've upgraded their sp offerings. I figured posting would lead to a good convo about the zinc

hopefully we can see a couple testers here shortly on both to see which will be better in the long run. I know a couple people had issues back then with M1 5w40 burning sometimes, but seems their chemistry changed with their M1 5w50.

Correct on the old mobil but it seems the new sp is better performing in the lab. Like you said, lots of testers would be great and with this popular thread, Im sure there will be many to follow.

Change the oil on my 2014 C350 with M276 NA engine using the Castrol Edge 5W-50. Put around 50 miles on the car today and it seems to really like the new oil. I am glad to have used the Pennzoil 5W-40 for about 3500 miles first as a transition from the M1 0W-40. The car does seem to have a better throttle response. I almost don't want to believe it because I've never had a simple oil change make such a noticeable difference. Then again, I haven't used such a high viscosity oil since around 1981 when I used 15W-50 (or maybe 20W-50 -- it was so long ago) in my 1981 Volvo 245 wagon (loved that car).

The best part is when you escape the vicious cycle of vanishing viscosity you enter a virtuous path where everything keeps improving:
The ECU tunes the fuel map from 900.Rpm
The TCU becomes more nimble to downshift
The chassis feels super light and responsive
The throttle is hard without any sponginess
No misleading numbers, just simple bliss.
Welcome to the party.
We've just pushed back a limit by improving pressure containment.
Now that we discover how touchy pressure is, it makes me want to know what else we're missing ...
The non-turbo ECU MAP setup is particularly sensitive to intake pressure... so I am going to go service my PCV disphragm & its restrictive discharge pipe.
At 65kMi I am sure my PCV refurb is going to register a difference now that blow-by is under control.
(I am going to pass on dealing with the well lubed HPFP roller to only replace silicone check-valve and vent tube).
I am due to lift up intake plenum again for old CPS.
