Not sure how @BenzNinja enables the AMG menu on non-AMG cars, but I would think he could do the same for an AMG car.

 

I have an AMG menu. It displays coolant temp and oil temp.

 

Right. But not the transmission temp. The AMG menu that BenzNinja enabled for me shows all three.

 

Jet,

What I am trying to say is, your digital Coolant Temp Data in the small window, is not ECM raw data, it is more like the Instrument Cluster analog needle doctored data.
If your digital Coolant Temp Data is from ECM raw data, it has to be exactly the same temperature as what iCarsoft is showing and it has to be 175F and not 192F.
I am sure these 2 photos below is only 3-4 seconds apart...yes ?

By law, I know that OBD2 data must be raw from ECM and not doctored value.
What I mean by OBD2 data is the minimum/basic amount of data via OBD2 where the law in the US requires the car has to output them. Usual emission thingy I suppose and coolant temp is a MUST.

Why don't you try from ambient temperature and till 103C /218F coolant temperature as per iCarsoft scanner and see what is the digital Coolant Temp Data in the small window is showing stage by stage, and'
also the needle gauge as reference.

.

 

Engine discussed above is the M157 right ?
I would love to see your coolant temp data at mini digital display and engine oil temperature , please.
M157 has the B40 3-in-1 oil sensor, an amazing Thermic sensor it is, real time oil quality sensor too, using dielectric principle.

If you can also log into your Xentry to N3/10 to verify Instrument Cluster mini digital display of coolant temp data , that would be a final confirmation.

I believe a true AMG engine would not place a needle gauge doctored data for coolant temp in the small digital window, as the minor but fast and honest temp changes is what we would like to see during a hard run.

 

I can try that. After I replace my leaking coolant tank this morning.

 

@S-Prihadi thanks for your comments. I understand what you are saying and agree. My point is that doubt was cast on the accuracy of the oil temperature reading because it is derived/calculated based on a bunch of conditions, but actually measuring the oil temperature (at least at idle and warm) shows that the displayed value is much more accurate (and reliable) than the values shown for coolant and transmission fluid temps.

All I was doing was trying to dispel the idea that the oil temperature wasn't good because it was from a map. Could you use you Banks equipment and do the same test?

 

I can't find using XENTRY where the oil temperature is reported/displayed. Even though it is a calculated value, there has to be some signal provided to the AMG menu item. I have checked for actual values in both the ME (motor electronics - ECU) module and the IC (instrument cluster) module. Any idea where it can be viewed outside of the IC display?

 

Out of curiosity, running on lm 5w-40 and doing the mod, would it matter road tripping in the heat? Thinking of taking the beast on its first road trip to Vegas, which is roughly 550 miles and around 105 degrees

 

It should be all right if your particular oil is "MB Approved" - Here is how LMolly was tested.

You can manually shift to lower gear such that your driving RPM is near the oil spray RPM or near about 2800.RPM in your case.
If you don't then it's back to stock dry-lube cylinders due to low viscosity oil needing higher RPM to build oil pump pressure

I'd translate this as current LM-5W40 sets you in MOD-1.0 only and not in MOD-2.0 with MOT-5W40.

Oil grade range numbers are misleading just like temp gauge.... marketing fluff all around !!!

 

oh wow, I thought liquimoly 5w-40 puts me at 2.0 and the solenoid mod is always on LOL. Is MOT motul?

 

Molygen 5W40 is perfectly safe to run in these. But I think want something thicker.

 

would running the solenoid mod with ceratec + liquimoly 5w-40 (purple container) be safe to
roas trip in the heat you think?

 

I don't like oil additives but probably yes.

 

I was thinking should be fine, in UAE where tasos resides it gets to 130 lol

 

@S-Prihadi I'm sure on the W166 ML 63 the digital cluster coolant temp is actually doctored.

Before MB discontinued the 'Mercedes Me' app last year I would have my phone setup to show a bunch of sensor data from the app, including the coolant temp, which moved around much faster and was consistently different to the cluster coolant temp (+/- 10 deg C). I am assuming the Mercedes Me app (connected via OBD port and BT connection) is using the 'true' ECM data.

 

Yes, me too, I was mislead to think
LM-5w40 would rival with MOT-5w40

It's close to a 0w35 with proprietary dry-lube package - A GREAT OIL, for gas savings.

MOD-2.0 needs viscosity to get pressure to cool pistons.
MOD-2.x saves gas with lower friction and efficient combustions.

Personally I would dump 300mL of 15w50 once (or twice) and not sweat a drop with spray cooling.
Doing this before a long trip may present schedule hazards... like a penicillin reaction

​​​​​I have not driven much with MOD-2.0 once it started smoking after 2000.Mi I naturally boosted my lost viscosity to spray at driving RPM.

When engine begins to store high-heat that smokes black oil, you're spraying too high 3000.RPM above the range of your driving RPM ... meaning you need to increase pressure to spray at driving RPM.
If you can't change oil viscosity, change the RPM.

I understand the limits of not "mixing oils"... Good choices are RARE, missing 10w40 or 15w40.
I don't know other way to get a 6W-42. Viscosity/pressure are super touchy with VVT positioning and confused TCU learning better shifts points.

Anyone can test anything they are curious about with self-approved oils, true?

AMSOIL would be interesting to consider. Their premium ester base is supposed to hold greater heat. Do they have MB compliant lube package??

 

so I just did the lm, I do like that oil so I’ll stick with it, you recommend driving it around the 2800 rpm mark?

 

That's unnecessary. Just drive normally. It'll make more oil pressure unplugged. That's the whole point of the thread.

 

I agree it won't be perfect but many ppl drive on that oil everyday without any concerns.

You'll get a mix of dry-lube savings and MOD-1.0 cooling - That's still better than stock dry up to 3400.RPM.


Your engine is cooled better, cleaned better and running better: what's not to like?
MB Approved oils are safe for MB Engines.

You're still gonna be better cooling than stock. Keep an eye on oil color turning. It's "normal", it will show you the reality of your hard working oil condition. No surprise.

 

I been logging engine oil temperature since early 2023 along with oil pressure and many others I place pressure or temperature sensors on,
along with all other OBD2 standard parameter my ECM is pumping out. Banks has two data bus, one is OBD2 data bus and one more is Banks own data bus when I add my own sensors.

But my engine oil temperature is not immersed in oil like M157 B40 beautiful 3-in-1 oil sensor.
My oil temp sensor is a K thermocouple attached to oil pressure sensor metal tip and this oil pressure test port where my oil press sensor is located....is engine oil ALREADY cooled down by oil cooler.
M157 B40 oil 3-in-1 sensor is at the oil pan, it reads engine oil BEFORE it is cooled by oil cooler and is more instant as it is in direct contact with the oil.

The log file is a combination of the two data buses. I even have a weather station sensor module to read atmospheric condition to see my turbo actual output in my HOT and HUMID climate.
I loose 6% engine power typically at my 30C ambient temp because SAE horsepower standard ambient condition is not met for my hot city.

 

I am liking this new blend of Mobil 1 0W40, SP rated.






Finally this afternoon I was able to do a proper test drive with this new oil and also for my wheel alignment .
105 minutes leg 1, break for a snack 30 minutes, leg 2 for 69 minutes. DONE.

Total distance covered 80 miles or more.
The first 105 minutes, has 36 minutes of stationary test to heat up the oil and engine really good.

Oil life during this test, under 500KM or 300 miles of use. Less than 2 months old.


The 105 minutes test summary. I will break it into two parts. 1st to 36th minutes stationary and then 37 minutes to 91 minutes. The last 10 minutes ignore it.





The highway I took is decent today Sunday. Little traffic , so I can maintain decent speed for testing RPM based oil pressure at 7th gear or lower.

Let's begin : Red right side vertical value bar is for RPM only. The Left value bar is for all other data.





.





...




......





Detail data for 1,500 RPM




Detail data for 1,750 RPM




Detail data for 2,000 ish RPM



All above data is oil solenoid DEFEATED.




.
Flashback......
If oil solenoid is untouched as is, the maximum oil pressure available until 3,500RPM is only 28 PSI maximum.





....





.
Oil spray nozzle activation if assumed at 30 PSI and higher, a good oil like what I am using now will be good at 1,500RPM as per table 4 images up, giving 38 PSI already.
In fact at 1,250 RPM it is already 34-35 PSI average







Visual for :01. Thermocouple 2A – TMP-2A is at engine oil pan outside skin, this is oil pan temperature and is not direct immersed in oil like B40 sensor of M157




.






..
02. Engine Oil Temp - EOT is K thermocouple at the body of the oil pressure sensor, so again it is not a directly immersed in oil.



.
Happy unplugging......the oil solenoid.

I've mentioned many times. As someone who has very hands on time with the m157 stock and 1k hp. I'd moved away from the use of 0-40. I realized years ago it was to thin of an oil burning off way to easy which is basically what everyone is now finding out about . Make the full switch and be done with the math and wasting time while your engines suffer. Lol. 5w50 all day . I prefer amsoil signature series 5-50 but I'm sure there's many other name brands that do the job . You do not need additional additives when you choose an oil that contains the protection you already need which for me amsoil has .

how do you guys feel about molygen liquimoly 5w-50? I may switch to that then for my next oil service in November

 

Don't know why it posted twice srry
