Now that I own vehicles that are using 0w20 and wonder if efficiency is gained at the expense of longevity, I feel better after watching this video.

I’ve just watched multiple videos on this topic.
Each one explains it differently.
One of them said that a 10 W 60 oil, relates to the viscosity at low and high temps.
It’s viscosity is a lower number 10 (thinner), at startup and higher number (thicker), at 100 deg C.
So why does the oil drain out better when hot than cold ?
I swear I will NEVER understand this.
Oh and yes...
Another oil thread.

It's the classic misconception Huzo. Think of it this way. Any oil gets thinner as it's temperature rises so a 40,50,60 weight measured at 100 deg C where the SAE measuring point is for engine oils will always be thinner than even a zero weight at room temp or 40 deg C where the low number SAE measuring point is. The upper number is an equivalency measurement or number for the oils viscosity at 100 deg C. So the upper number says "this oil is equivalent to" an 40, 50, 60 weight oil at 100 deg C all of which are thinner than a zero weight at room temp (40 deg C). Two different baseline measurement points. Think of it as two separate viscosity measurements one at 40 deg C (lower or W number)and one at 100 deg C the upper number just put together for convenience of identification.

Ok Phil.
I’ll digest your words.
