Agreed. I can feel no difference.
But I still change my oil. I know my engine needs to be properly lubricated and the fresh oil keeps deposits from building up inside the engine. I do this to make sure my engine lasts as long as possible
And that is the reason I add TC-W3 to the fuel...

You may have to explain this one a bit...
I'm no connoisseur, but I enjoy a variety of white wines. I really don't care for any of the reds I've tried, and many are completely undrinkable. I think I would have a real hard time confusing the two
The only study I could find related to this was
The Color of Odors
Where 54 undergrad students failed to recognize that they were being actively deceived. They were given two glasses of wine, both the same white wine, one with food coloring, and asked to describe them. None pointed out that the "red" wine was really a white, but they did use some traditional white wine descriptors for the "red". It does mention that people could typically tell if an opaque glass of wine had a red or a white with 70% accuracy from smell alone.

Agreed under normal operating conditions. However, at extreme cold temps, the difference in viscosity can get very noticeable, especially in the tranny/rear end.
