I have not read one good argument for why 229.5 is critical, especially with good used oil analyses from non-229.5 oils (including good old Rotella T6).

ROTELLA SOLID VISCOSITY
Not the oil type that rushes to be W30: real protection insurance to go the distance.
Now about the high ZDDP... it could be fine as long as engine doesn't ingest oil, cats/lambda won't see much of it, right?
ZDDP is so effective that I was thinking about running T6 next but I don't want to stray from my already unusual path to help reproduce results.
I might give this T6 a shot next year not to introduce too many variables

Not sure if this is relevant to this thread, but skimming above, I got the impression that the engine problems went away on the 205 with the 2019 model. Perhaps not..
Another 274 engine problem: Car is 2019C300 4MATIC with 51,200miles. Just had a major repair of the engine to replace the "Directional Oil Valve". I think it's in/near the oil pump. The Check Engine Light came on solid, and I took it to dealer right away. They had to disassemble nearly the entire front end: frame, suspension, steering, axles, engine mounts, ... I purchased the car on 12/07/22 and bought the extra 2 years of warranty for $2745. This repair would have been about $3,100 if I had not bought the extended warranty.
If you like the W205, I'd wait until I found a 6 cylinder version. Here's some data from Wiki:

I would not call it KoolAid, though I agree to some extent. The MB spec is a variation of the EU spec.
The important part to me, is the comment from Lake Speed Jr about the "package" since the " package" is based on what the oil encounter: alloys, surface finish, coatings, ring design, etc.
As I have mentioned before, the advice I got from a trusted provider of components to several high end automotive manufacturers was: higher oil pressure can only help, just be careful not playing with oil package. The oil, the engine, and several components are "tuned together". Whatever that means is to anyone to interpret

Now your engine managed oil pressure is back in stock MOD-0 condition.
You can regain all the fuel savings with the advanced 0W-40 lubricant.

PFL205.064 with M276.823 (Oil pump solenoid defeated)
The C 450 is pretty much identical to the C 43 other than the C 450 not having a few stuff like (When I meant C 43 in this comparison, I only meant the W205 pre-facelift C 43, the facelift C 43 has many cosmetic changes which I outlined here: https://mbworld.org/forums/c450-c43-...ml#post8858401)
The C 450 was called Mercedes-Benz C 450 amg sport
The C 43 was called Mercedes-amg C 43
The C 450 was available in Dakota Brown (796) while the C 43 never had that option (if I recalled correctly)
The C 450 doesn't have the amg badge in the tachometer but still gets the checkered flag style.
The C 450 has an amg badge on the fenders while the C 43 has biturbo and 4Matic.
The diamond grille of the C 450 does not have the amg badge while the C 43 has one, similar to the diamond pin grille of the pre-facelift AMG GT.
The C 450 has the amg and C 43 badge in the rear while the C 450 has the C 450 and 4Matic badge.
The C 43 has amg on the engine cover while the C 450 doesn't although early C 43 production models doesn't have it either.
The C 43 has a performance exhaust option and the C 450 doesn't.
The C 450 has the amg speedshift 7G Tronic+ while the C 43 has the amg speedshift 9G Tronic and the non amg speedshift base transmission first appeared on the W213.
I think the suspension of the C 450 was softer than the pre-facelift C 43, the facelift C 43 suspension was a huge improvement.
The C 450 calipers have Mercedes-Benz while the C 43 calipers has amg badging.
The C 450 doesn't get the amg screen with the oil temperature, transmission temperature, boost etc. but was available after an update.
The C 450 doesn't have a boost sensor if I recalled correctly so even after having the amg screen, that boost meter never works.
The C 450's infotainment startup amg logo is different to the C 43.
The C 450 shares the same brakes as the C 43 just the caliper lettering is different.
The C 450 might had came with red seat-belts standard.
The C 43 steering wheel also got an amg badge
The C 43 had access to the amg private lounge the C 450 didn't but was also opened up later on.
I forgot if the C 450 had amg branded floor mats but amg line C 300 had it so I would think it did too.
I forgot if the C 450 illuminated door sills have amg or Mercedes-Benz.
If I recalled correctly, the C 450 called it Agility select while the C 43 called it Dynamic Select for switching drive modes.
Those are the differences I observed after comparing the two vehicles back then. I might had missed something though.
Personally, what the C 43 sold me over the C 450 was the performance exhaust and the performance not the amg badge. I rather it didn't have an amg badge because it would had been cheaper in both insurance and maintenance. amg tax is a real thing. I also rather it was kept as C 450 because the W202 C 43 was if I recalled correctly one of MBs' first AMG plus that had a V8 but that's story for another time. Other than that, I love the C 43, main thing I love about it nowadays really is the fact it has a M276.
The C 400 is basically a C 300 but with the M276, the horsepower is less than both the C 450 and C 43. The C 400 doesn't have the slotted/divided exhaust tips (I know it is fake) as the C 450 and C 43.
Despite the C 450 not having performance exhaust, it still sounded somewhat different to a C 400.
Well, back on topic for a second, this oil pump solenoid mod is awesome : )

I think you only made a small mistake. As I could remeber, the C450 has a standard 7G Tronic Plus. There was never a Speedshift Transmission. Maybe the C450 AMG had a little faster shifting time, but the transmission was never a Speedshift. But I could be wrong, It's a few years since it was actual.

I did not know this. I have the @BenzNinja tranny upgrade that adds Sport+/Agility mode to my 7G Pluss transmissions. I think I will test it out to see if it works on my non-AMG transmissions. I know previously, when in M mode, the transmission would still automatically shift when about to stall or at redline.

MB is pretty conflicting what they want to call that transmission.

Mine is 7G Plus tranny. The M mode will shift upon redline and will downshift when engine RPM too low aka bogged down.
If MB does not allow shift up in redline in M mode, it will then need to cut fuel like oldie manual car with EFI when over-revved....otherwise engine will suffer.

It’s boat season (as well as audit season, ugh) for me so I have not been paying attention to much else.
Glad to see there’s still a lot of chatter!
I’m due for my B service according to the IC - will be switching over to a 5W50 during service.

I saw some posts in the thread regarding coolant temp fluctuations from the dash screen to real time. Here is my findings after data logging today in 78-83 degrees, driving on open highway around 80mph I was about 12-13 over the mb coolant screen and in traffic as high as 23 over.

That got me curious, since you mentioned over-revving, reminds me of this I came across on someone's car that was over-revving, it looks very bad I wonder what happened, why is the ECU allowing the car over-revving. https://mbworld.org/forums/c-class-c...-problems.html
