Very informative. It makes me think I should do my first oil change or at lease replacing my oil filter with the CM dept Filtration element filter.

One aspect I've been looking for an answer to;
what's the distinction between Mobil 1 0W-40 European car formula, and Mobil 1 0W-40 Dexos, other than a big price jump?

I think the Motor Oil Geek Mobil 1 vid did mentioned a slight chemistry difference in the higher amount of ZDDP in Super Car oil? Maybe with the failure of the LT6/Z06 that they altered the formulation? I am just speculating? I have to watch that again in the second part of the vid where he compares 0w-40s including Super Car.
Given the difference in price between either oil and the cost of replacing an LT2 engine, owch, I would definitely be using the factory recommended lubricant. Even if you were lucky enough to have it done under warranty there goes most of the driving season likely. I can’t figure out why with the small difference of a couple of bucks a litre that anyone wouldn’t really. After all these are $100,000 + vehicles. Oil cheap, engine expensive. Oil Geek guy certainly seems like he really knows what he’s talking about.
There is a .0000000001% chance the difference in the 2 oils would cause engine failure. However, I do agree if you are under warranty. Don't give GM any excuse to deny.

I was just thinking that most of us doesn't drive our cars in the winter that adding a mixture of 2-3 quarts of Mobil 1 15w-50 track oil for an slightly thicker oil film protection/wear. In the vid, he said that a thin oil will give the max wear protection at higher piston speed. Since 99% of us doesn't consistently shift at 6500, a slightly thicker oil will give it the best protection at normal shifting 2500-3500, logically thinking?
I can do that at 5k interval between oem recommend oil change interval at the dealership.

GM when it comes to warranty claims are probably as much fun to deal with as an insurance company…….
Instead of watching 20 minutes of Geek guy, I drove through the car wash, dressed my tires and met a friend for lunch. Ok that sucked up 3 hours of my day and the oil thing would be over my head lol...
If you think about your vehicle that you do drive all year round regardless of the engine oil type the viscosity changes significantly depending on the time of year. Here for example we can have a temperature difference of as much as 80 degrees celsius or 175 degrees fahrenheit . Use the factory recommended oil and go light the barbecue and open a nice red .
And don’t forget to oil the grill…..

I'm not that fancy...
Couple more draft here , thanks….
I agree, use the Dexos at whatever cost, to keep GM happy.
But it's not just "a couple of bucks a liter". I was getting 5 quart jugs of the 0W-40 Supercar European formula for my Hellcat at Walmart, in Buffalo for $28 usd, ~$40 cad a few years ago. OK, not really relevant.
On Amazon, it's currently $77 cad for the same 5 quart jug.
The Dexos is $61 for a single quart, $179.99 for a box of 6 singles.
It works out to $15.40 compared to $30 per quart.
So far, GM has given me 2 free oil changes, (5k & 12k), and, because of the hassle of the cost of a DCT filter change, they sent me a letter for a 3rd free oil change sometime in the next 12 months. All are using dealer supplied Dexos, of course.

Attention
, go invade some garbage bins or something.
And if you are the homosapien version, go get another car wash and a few of these
!!!!!
I have heard of this before from an instructor that works for Petro Canada at one of night class years back.
Ie.. It is best to choose an oil that has less range ie 10w-30 vs 5w-50. But that does not meet the requirement of the oem that mandate an oil for extreme temperature range. More addictives has to be use.

Where does no range fit in? SAE-30? Besides in my lawn mower ...

I think straight grade for racing normally because the absence of additives that wouldn't break down the oil during racing? That's my guess.
That ball bearing test doesn't make sense to me.
If 5w30 oil cold acts like a 5w it is supposed to act like a thinner oil and the ball should drop quicker, not slower.
I know cold oil should be thicker and should do what it did, but that's not what he was trying to prove.
What am I missing?

All oil regardless of rating will be thicker when cold and thinner when hot obviously but for cold extremes like -40c you should be using a 0 weight is what I took from the explanation. I had a 1989 GMC that called for 10w30 conventional oil and when I simply changed to synthetic oil the difference in how it would crank at -40 was pretty significant. The synthetic was also 10w30 . Was with a friend who had to move an old van from where it was stored one February day back in the eighties and he remembered that the oil was low and wanted to add a quart which he had in the box of his pickup. Took the cap off , turned it upside down and nada , lol . So imagine that oil sitting in the oil pan when you go to fire the engine. It was about-46c that day. Ambient.
