Don't forget you mentioned API SQ is coming out, and here I am still waiting for API SP x-cess gen 2
Oh boy, like waiting for a new phone to release or something. There is always something newer.
The way inventory are reduced everywhere, the newest SQ formula is going to target the masses of Toyota/Ford 1.8L 4Cyl. turbos with "gas saving" formula... the greatest burnt oil for 15kMi.
Chemical limited lubrication with dismal viscosity is not what ECU need to seal rings. Bosch will need to revamp timings computation for drafty cyl.

I will stick with SP then The API SP(ecial)/S(u)P(erior) formula.
We know available inventory vary, sometimes older SN, sometimes newer SP: Prefer 5w-40 API-SP over SN in a PAO grade.
whatever it is called (clean/xcess/power).
The key is to not use effective viscosity to redline your turbo while your rings are far from sealed.
Just keep up Rpm above 2200 to keep up spraying not burning to make cleaning/sealing progress.
> NO QUICK CLEANERS...
-- A while ago we talked about CLEANERS, flushes...
Cleaning engine surfaces removes protection.
-- You don't want to stress high-output without surface protection.
-- It may be safer to go slow cleaning route... Hence using only semi-effective viscosity for now and no harsh cleaners.
It's possible... I don't know how safe given redline habits.
then i will order power 5w40 since seems to be a bit better than a xcess

ohh.. it seems you will be 2 ish specs behind (i can't believe that you can't find it anywhere online that is avail too...)
2015 SL400 (M276 Turbo), 2014 C350 Sport (M276 NA), 2004 SL500 (M113), 2004 Audi TT225 (BEA)
Still, I think I want to wait until they get an MB approval. Sadly the new Castrol Edge does not come in 5W-40. That seems reserved for Castrol Edge Euro Car formulas.

Not me. I'm still using SN in my C350 (only because I had Molygen 5W-40 to use). I will likely continue with the SP rated Pennsoil 5W-40 in my SL400.
I also am using the Pennzoil Euro 5w40 in the c450 (same 3.0 bi turbo m276 engine as your sl400).
I was using Molygen before but found pennzoil is much cheaper and is of good quality/cleaner from what I hear due to natural gas.
Why did you switch from 5w50 again?

idk how cheap is on your side but in my country 5l cost 130usd...

I'm sure the Castrol Edge is great oil, but it did not have MB approval and I want something that is MB 229.5 approved. I bought a bunch of it, so I may use it in my 2004 Audi TT. Lots of miles on the car (>255,000). But oil has been changed no more than 5,000 miles during that time. It may benefit from the 50 weight portion.
pennzoil
motul xcess gen2
amsoil
m1
etc etc anything that is 05w40 api-sp and sn rated
Engine oils products are like tires... they are vastly different from brand to brand and models.
5w-40 oils can get greatly oxidized with age and heat.
(full synthetic vs. PAO)
amsoil /motul /...
m1 /pennzoil /...
I noticed that true PAO synthetic oils are never cheap.
