Maybe the fresh oil change "Butt Dyno" is right?

Mahzurrah!
Stumbled on this on another forum. Interesting. I know I can tell the differences some times.




I am certain the "new oil" must be Castrol Magnatec!

They made one mistake, and possibly two: First, they didn't take the sample mid drain; and two, did they take the sample cold?

Not really any 'informative' information there, usual 6:00 news flash.
 
The oil they drained looked sort of gunky to me, but I guess I'd believe a half a second is about right.
 
the only time that I have noticed a difference after an oil change this when I put 17000 on Castrol Edge in my Beamer. The other time the transmission started shifting smoother after I did a power steering drain and fill. I don't believe in the butt dyno
 
Sounds like placebo effects. If maintence on a car is done often then butt dyno is all in the head. Run a car 25,000 mi on dino all in town and change the oil? Well it will seem faster and maybe even faster as the motor is falling apart as you drive down the freeway and all the nuts and bolts you lost caused a stage 1 weight reduction. Followed up by a stage 2 which involved a bank reduction as now you need a rebuild.
 
The oil that came out of that car looked black.

If lower viscosity oils improve fuel economy, why shouldn't there be an improvement in power?
 
Nag there was something different, and it wasn't the oil.

Note between runs 1-3, it was pretty consistent.

Between runs 4-6, there was 0.4 seconds between 1 and 2, and 2 and three, about the same difference as the old/new "facts".

Something changed...

Can you hear a piccolo in a full-on orchestra? Can you feel a kettle drum thru hi-fi loud speakers?

Less oil drag means less parasitic loss. Whether thinner oil translates to faster lap times let's ask nascar since iirc they use thinner oil for qualifying don't they?
However in the real world I can't say for sure.
A person who spends enough time in their vehicle can certainly tell if something is different. I know I can.
