Why straight oils cool better

If a liquid doesn't have as much heat absorption transfer rate and/or heat holding capacity then it's not as good at cooling (absorbing heat) as one that has a better heat absorption transfer rate and higher heat holding capacity.
Do you have a link to valid test data that shows the difference in heat transfer and heat capacity of a bunch of different oils, or a link to an article that says oils with ploy VIM don't cool as well?

What?
Water has a rather crappy absorption rate ability vs say aluminum, yet has really good holding capacity.
Anyways. Maybe someone who knows can answer?
I would also like to know how the VIM's affect the 3 modes of heat transfer.
You gonna use liquid aluminum as a cooling liquid? lol.
Water has a high heat capacity, and absolves/conducts just fine. You've already went obtuse.
Can you find the same data for all these oils you're talking about?

I bet nobody can find any technical data that shows any real difference between motor oils in terms of heat transfer rate and heat capacity. If there even is any difference, it's going to be so small that it will never make a real difference inside an engine.
Maybe someone who knows can answer? It's ok for you to say you just have no idea and let someone else take a stab at it. Btw, has nothing to do with the liquid, it has to do with the solids, hence why the OP (post #1) says "VIM's".You gonna use liquid aluminum as a cooling liquid? lol.

You have 10 fingers and a keyboard ... why don't you go find out for yourself (that's what engineers do) instead of always trolling and asking guys here to do all your research.
You've made the claim that certain oil formations don't "cool" as well, and I asked you to post the link(s) where that's coming from, or is it just coming from some random miconceptions and thoughts?

Was not asking anyone here to do research. Was asking if anyone here had the knowledge. The 1st few words in the post were "Who here has the knowledge", so you took that to mean I was asking someone to do research? Are you knowledgeable on the subject?
My claim is factual, was wanting to know, again, "Who here has the knowledge" ?
You have 10 fingers and a keyboard, no?
I gave you the basic knowlege in my first post. If one oil forumuatioin has a higher heat transfere rate and higher heat capacity then it will cool better. Now show where there's tecnical proof that varies between oil formuation as as a function of VIMs.
You gave knowledge? My apologies, I somehow missed it.
Post #11, You read that link already and understood it?
And please show how exactly that corresponds to motor oil formations, and cite data showing how it effects the cooling capacitly of specific motor oils. You seem to make huge leaps in your "logic".
All the data is in that link. The base liquid does not matter. Huge leaps? Yeah, huge leaps I guess.And please show how exactly that corresponds to motor oil formations, and cite data showing how it effects the cooling capacitly of specific motor oils. You seem to make huge leaps in your "logic".
Who was it here who has the minor in Chem? Was that Astro14 or someone else? I forget, it's somewhere in the messages area.
Then explain it in detail how it would apply to different motor oil formulations. You talk like you know, but you really don't and you can't apply that article to an oil's specific formulation. You can't back up any claims you ever make in any of these threads, they are just tolling exercises in futility that just keep going in circles and get up locked. You might have a recored for locked threads as a function threads started, lol.
Look in here too, see the VI's (the PMA1, PMA2, and PMA3 groups).And please show how exactly that corresponds to motor oil formations, and cite data showing how it effects the cooling capacitly of specific motor oils. You seem to make huge leaps in your "logic".

I related them, motor oils use polymer VIM's. There, simple relationship.
Download that PDF and read it ... it says absolutely nothing about how the polymers change the heat transfer or heat capacity of the oil. Come on, find something that actually talks about the polymers (VIMs) changing the "cooling" performance of the oil - it's heat transfer rate and heat capacity.
That's a leap ... show info that proves it changes the cooling performance of the oil. So far you have 2 strikes.
