Okay..
May I ask how?
Did they actually have 2 equal S2000's, one with 10W-30 in the engine and one with 0W-40 in it?
Could you please explain to me - now dont be shy and throw the most difficult mechanical reasons and calculations at me - why the difference in thickness @ -2C between 5W and 0W is not noticable in an engine, the F20C in particular.
About the cognitive dissonance.
Why do you think I "suffer" from it? I ment no disrespect when I posted that you could "suffer" from the side effect, I forgot the ""
Let me guess : I paid a lot of Euros for that oil therefore I want it to make a difference.
Fact: I paid less then of-the-shelf because I ordered it in bulk.
Let me guess again: I paid less for that oil therefore I want it to make a difference.
That way I never "win"
Honest: this is not about winning at all.
Cross-my-
-and-hope-to-die: I noticed the differences discribed in the initial post.
It looks like this night is going to be a cold one.
Cant wait.
Also beacuse it looks like it going to be the last one this spring so that means TOP DOWN on Friday morning.
Woo Hooo
FAR GREATER minds on the subject than you or I have already disproven your "perceived change"

Road Rage posted his opinion about Mobil1 0W40 on June 07, 2004

"I am impressed by the 0w40 - esp the very high flash point. That could be a great all-season oil for people in cold and hot climates. Delvac1 5w40 still gets the nod for longevity and POM for longer OCI's."

It all comes down to whatever helps you sleep at night. If he says he feels a difference, and it's costing him less, then i'd have to say he made a smart choice. If someone else on the other hand would rather do a highly controlled experiment before they buy a certain type of oil to be 100% sure that there is a difference, then so be it.
How did this turn into an oil discussion?
okay.
Talking about how things "feel" and "sound" are by no means scientific measurments. I fully agree on that one.
But I did notice it.
And I never mentioned HP gain, btw.

No, I did not time it.
And agreed: outside temp -this morning and last Friday - was measured in our garden, thats the only "scientific measurment" I took.
Last Friday it was -3.1C in our garden.
As for driving at same rpm at the same spot.. well.. a daily drive to work can get very simular, a routine would be another word.
The engine reached operating temp this morning "at the first farm after the righthander".
Last Friday it had 3 bars "at the 3rd farm after the righthander", about 1,7 km down the same straight road.
This means nothing to you but it does to me.
I reach the first farm after 2,5 kms from start in my garage box.
Take the 3rd farm as 100 %, the first farm is 40,5% sooner.
40,5 % is not just a perception, is it?
How do I know all those numbers? I wait for 3 bars before I turn the heater knob from cold to hot (this "proves" another equal setting). My engine has priority over me getting warm, I wear a jacket
, but the sooner the better, thats why I'm watching the temp gauge. The road i'm talking about is the same one i drive to work on for about 4,6 years now
Tire pressure was steady all week at 2.3 bar in front and 2.4 at the back.
(I check the pressure about every weekend, when I do oil level check
Reading this back makes me feel like a car freak
The oils I'm talking about are Shell Helix Ultra.
Flashpoint (Cleveland oc - whatever that means) = 222 C.
Having that oil in my engine for 10000km doesnt make it old, more likely at half way its life. It came out brownish, but clear enough to see through.
About your own experiences: have you ever tried 0W-40 or 5W-40?
I'm curious.
I'm looking at the BobIsTheOilGuy right now and they have a banner : "Your engine is talking.. Are you listening?"
Should I reply: "I am listening, but no one listens to me"?
okay.

Ok, so let's say you "timed" it with a stopwatch, which you didn't. Here's the scientific part. Did you measure the air intake temp at all times from the moment you started the car to the moment you reached 3 bars? How about barometric pressure? Engine coolant temp? Oil temp, and at what location in the engine? Ambient temperature outside the car and in the engine bay? Did you drive the car at the exact same rpm at every single spot on the road as you did before? What about TPS and accleration? Were they the same at every spot before as after? etc, etc, I could go on and on.

0w40 yes, 5w40 no.
anyways, as I said, while you may feel this oil lets your car warm up 40.5% sooner (you really should count the distance from your home to said farms, not from one farm to another), it's just an observation that really doesn't have any measured tangible backing.
so could it assist in "faster" engine warming? maybe, but your observation is not conclusive enough to decide. 
but again, if you'd like to try and "wow" the real experts, post it on BITOG and see what kind of responses you get.
in fact, I'll do it for you if you dont want to.
