LSJr tests and discusses DexosD babymax oils

[johnmyster]

On tonight's episode of Oil Geek, LSJr gets coffee for Jeremy Wagler and his assertions break the BITOG HDEO forum.

0) DexosD is only 0w-20 (incorrect.)
1) Run 40wt in your LZ0/LM2.
2) Higher viscosity means higher peak torque.
3) Delvac 5w-40 CK-4 (current formulation) is PAO/ester.
4) Mobil ESP 0w-20 is better than Delco bottled 0w-20.
5) For LSJr, lower wear metals tells the whole story.
6) Modern VIIs in high-spread oils hold up pretty well, despite warnings from our grandpas as they taught us to change oil using fram orange cans.*

@Hohn i wonder if the higher viscosity / higher peak power helps explain your mileage improvement that I saw awhile back.

 

[BobsArmory]

I bought a bunch of ESP 0w-30. When I run out I might go to the 0w-40 esp.

Hmm.

If like to try ESP 0w40 but it doesn’t seem to be available in Canada unless you want to pay a high price. 20 and 30 is available.

scientifically this makes complete sense for a low rpm torque making engine. first thing comes to mind would be a large semi they're not running low viscosity oils.

With the approvals requiring a minimum HT/HS there’s actually not a lot of difference between the 30- and 40-grade.

More boundary layer of the 0w-40 giving more power and less wear metals in a low rpm diesel engine makes sense. Even in a gasoline engine I think it would be good for me as I don’t live above 3k rpm 90+% of the time.

Lower pour point is nice for winter in the Canadian prairies

Exactly what several members here explained to me for my 3.0 a while ago when I first joined BITOG. Took me a while, but I finally saw the light.

I noticed he didn't say much about the TEOST. He mentioned the results were consistent, which they are. I'll message him and see what specific TEOST test it was and what the passing range is. Goes back to the question of its relevance. I don't have an answer. Amsoil uses it and actually did a relatively recent test of M1 HM and Valvoline HM and both technically failed the TEOST. Valvoline and Mobil know what the TEOST is and can run them in-house. So I'm thinking they either chose a chemistry that gives up some deposit prevention for another benefit, or TEOST isn't as accurate at predicting deposits. This is where Red Line, HPL etc. come in.

I noticed that as well. My thinking is it wasn’t the focus/purpose of this video so he didn’t expound on it. Or, like you said, isn’t really a relevant test. Will be interested to hear his response

I sent him a message he's great about responding.

But really, only if it results in a lower winter rating. A low pour point doesn’t necessarily equate to a better winter rating.

But agreed it is not a bad thing.

A few more nods for the Mobil 1 ESP line …

 

[Pablo]

Isn't the basic point here, it's not that "mysterious"??

Would Mobil 1 ESP X4 0W-40 not get the job done?

That’s what he says in the video

 

[Z28racecar]

Awesome to see a video exclusively for the babymax. I'll be switching to 5W-40 my next oil change, I have some Amsoil euro AFL waiting.

Mobil really did a good job with the ESP and delvac line. PAO for off the shelf prices and good add packs.
