I was wrong-oil is thick when it is cool

[jorton]

How can room temp virgin conventional 10w30 be this thin?

It seemed to be about as thin as the old oil I drained hot. When I poured it down the medium size funnel it didn't back up at all. I think it runs through the hole like 5w-20.

This Valvoline has a strong, sweet(not burned) smell. Which additive smells like that?

There is perceived viscosity and real measured viscosity. For example, people for some reason perceive the viscosity of synthetic oil to be thinner, even though it may have the same kinematic viscosity as a conventional oil. That said, Valvoline is probably using some good group II base stock.

I hate the smell of Valvoline. Everytime I work on my car I smell that smell for hours

At room temps, I can't tell any difference until 0W20s which are like water at room temp, but if you really want the perceived viscosity-experience, drop em in the freezer.

As the Pabbs said however, our puny observations of oil in the bottle at 10 below 0 are hardly representative of the reality of the inner engine.

Here in the frozen north we just leave the oil out in the garage and mid winter on a cold morning say -35C give the bottles a shake and see what moves.

Sorry but if it ever hits -35 here I'm staying home by the fireplace...I don't care what happens to my oil.
