This is what i was thinking as well based on what I learned here, but since im not an expert and he is doing remaps I didn't want to say im right/you wrong, that's why i left the discussion without any arguing as I might not know something else around this
well mine is unplugged for already 3k km, im just waiting for my next change of oil (more 4k km) since MB did 0/40 AMG oil (instead 5/40 as always) and i can say is complete trash based on my driving (more sporty) and the car is sluggish the engine is vibrating when stand on traffic light or parked and the transmission is bit jerky (don't know what is doing when is changing gears) apart of that the oil is still "gold" ish, i did not remember before unplugged when i check regularly my oil on what km what was the color, but here i remember that i read that after 2/3k km ish the oil is looks darker (black ish - "burned" already)
thanks for sharing opinion on the attached screenshot discussion, appreciate that as well
What’s up everyone, so I’ve had my solenoid unplugged for like a year now on my modded 14’ E550. Been good stuff since then but now that we’re on the topic of oil choices I’ve been trying some different stuff due to my oil report with Liquimoly 5W40 Leichtlauf showing that viscosity is right at the bottom threshold for averages.
These are the oils I’ve tested:
Leichtlauf 5w40- What I normally run but has the low viscosity averages
Molygen 5w40- Seemed to run fine, however due to not allegedly having cats I smelled what seemed to be oil burning. Every time I came to a stop I smelled it, don’t know what caused that but going back to the blue bottle the smell was gone.
Redline 5w40- I used to run this before on many cars and loved it for the ester and the thickness, but seemed like they changed their formula as it didn’t feel or sound like what it should compared to before. Few K miles and it ran just fine no problems but harder to get for oil changes. Forgot to do an oil analysis on it so can’t compare averages
Right now I’m seeing people change to 5w50 and Motul, their 300V is really good stuff however I’m sure with our tolerances it’s not really ideal for our engines.
Honestly I’m looking for something that even with heat runs thicker than what I’m using right now, and especially since I run an E40 blend with my tune when I race, need something that’ll help against cylinder wash with the ethanol. Anyone got some good input?
This is the oil analysis I did last year at a 3500mile change with Leichtlauf, I use Ceratec and occasionally VP octane boosters when I was running 93 octane. (Oil was added cause I always forget about the offset)
@Kanoosh I am thinking the exact same thoughts. I was (am) trying to get LiquidMoly 5-50, no one near me has it on hand. FCP has it, for some reason I have not submitted the order. I have been on 5-40 Moly and cant say it was 'bad'....as if I would know anyway.
I can say with Moly I was not asked to or needed to add oil in the past 4000 miles. 0-40 Mobil1 would want me to top it off at some point (with or without solenoid unplugged)

Your racing calls for racing oil. No sense in burning "gas saving oil" for that application.
Racing heat trashes viscosity through the floor where the last resort is physical ZDDP layers. Catless is perfect for tracking with mapped fuel.
Don't expect the powertrain to see high mileage. That's not what racing is about.
Stock oil pump may not preserve racing engines. Pressure above 60Psi may be beneficial...upgrade to a 90Psi fixed gear pump. Some race teams go the other eay with limited oiling to save HP on each engine swap.
### Racing oil formulation is not compatible with cats/lambda.

To somewhat finalize the discussion on oil types for the M157s, is it advisable to switch from 5W-40 to 5W-50? How common is this change among users, and what is the track record in terms of mileage since the switch? Is there definitive evidence that the higher viscosity oil provides better protection against engine wear and improves long-term reliability? I have been using Liqui Moly Leichtlauf High Tech 5W-40 and am considering whether moving to 5W-50 would offer any tangible benefits, or if it would be unnecessary in my case.
Thank you!
I was a Ford powertrain engineer for years so reached out to some colleagues who specialize in tribology (lubricants).
Ran him through this whole thread and told him I settled on Motul 5W-50. That oil exceeds MB 229 specs, especially for LSPI, and is equivalent to the special oil which Focus RS specifies.
Regarding the oil pressure solenoid, he said “lose it!”. Durability clearly suffers in severe usage when such fuel efficiency tactics are employed.

Any significant differences switching to Motul 5w50? How long have you been using it for on your vehicle?
Just applied steel zip ties to secure everything - and it's amazing how quiet the engine is at idle now ...
Peter, now you know why I call this "dry lubed"
(MS! is not gonna like me saying:)
we can hear how more quiet engine idles... you can imagine the end of that journey being smoooth even cylinders contributions. Including vibration-free engine at driving RPM!
The noise and vibrations are from suboptimal frictions - We don't need to put up with thin film.

The bottom line... We would do well to collectively research: -- how to successfully clean carboned piston rings
without LSPI melting anyone's pistons.
Let impatient ppl contribute research or experience skipping over to 15W50.
I have already reached the clean side of the oil upgrade, now with limited incentive.

I just finished 5000 mi on the new Valvoline restore and protect in the Wifes Jeep Wrangler with 155000 miles on it. The valve train is quieter at initial start-up. I was in a hurry and forgot to save a sample for testing.
Just use Motul : ) I guess you could also switch to 5000miles/8000kilometers intervals as well.
i change my oil every 7-8k km and i was thinking which oil to choose for my next change since till now i used only Mercedes one, i was thinking for Mobil 1/Motul/Liqui Moly but I might go with Motul if you recommend it, can you tell which one exactly i think @CaliBenzDriver mentioned to be SP, if so i guess i should pick this one MOTUL 8100, X-CESS GEN2 112351 as this is SP?
btw: i think isn't that darker (burned) yet, considering my driving as it's stolen

Oh I rev mines out too, constantly, it is my daily driver but also my fun car so when I hit the twisties, I rev it out. Don't worry these cars really appreciate the Italian tune up.
I am using Motul 8100 X-Cess Gen 2 5W-40, the engine purrs at me. Forum member JettaRed also had excellent experience with Pennzoil so that is worth considering too.
Oh ya, I forgot yours is tuned as well, so that plays a role too, was it stage 2? I would also shorten the duration of spark plugs service as well.
What is the engine oil temperature at just cruising maintained at when warmed up? What about the highest temperature the engine reached? Do include the outside temperature as well when you record this information.

mm not sure if it's to me but yep im running stage 2 during summer here gets around 38C but when i unplug it was almost end of the summer, so ambient it was around 32C with 5W40 Mercedes one was around 8k km already the oil, normal driving i was keep 103-106C and when i push it a bit goes to 114C and then cool down to around 107-109C (im with BMS intake so it's heat soaked, also I run the "IC pump mode" all the time )
then Dealer changed with 0W40 AMG ambient temps was around 28C with normal driving 98-100C and when i push it goes to 112C (considering is new oil maybe that's why had 2-3C less difference between the temps with old oil)
at the moment ambient is around 10C, normal driving 97-101C and when pushed 104-110C
last year the dealer changed my plugs, since then i have around 20k km, so not sure if they've to be changed (not sure on what interval i should change them as well when you are tuned tbh..) and on next change should i go with OEM ones again or should i pick something else considering isn't stock?
