re: Is 0w20 really what is best for our vehicles?

No they aren't. Bearing/ring clearances are chosen for thermal expansion and the dimensions of the parts involved. Honda Civic will spec 0W20 here but 5W40 in the EU for the exact same engine, nothing to do with bearing clearances.
Yes they are, the engine in question the 0w-20 meets the viscosity required for the journal bearings to work properly. So does a 30w and a 40w probably does too.
You aren’t going to damage an engine running 20w that calls for it. And you sure as hell aren’t gaining anything by running 30w but you certainly can if you want.

In US 0w20 is suggested for efficiency and emissions.
If you look at other countries recommend viscosity in the manual it's 5w30 bc other countries aren't run by liberal retards.

I started running the T6 Rotella I'm everything that's not my vehicles.
It worked so well and didn't break down in my generator and is JASO wet clutch certified for my Honda 4 wheeler....
I been putting it in my lawnmower as well. Been great

My rule of thumb is any 5w40 that meets the latest Ford powerstroke spec is about as good as it gets. Ford is paranoid about diesel engine oil since the 6.blow, which was really hard on oil.
Heavy duty wet clutch rated oil is some good shite.

I genuinely have no idea why my engine in this country requires 0w20, whilst in another country it requires something different. This is the same story for many different countries.

In my experience, if the government is suggesting that you do it, you are sacrificing your engine in order to save the environment. 2 cycle motors once called for twice as much oil as later two cycle engines. Less smoke and less pollution but less protection
20 weight motor oil is thin and a similar situation to the two stroke oil requirements that we seen.
The thinner oils are supposed to cause less drag in the engine which yields more fuel efficiency but how much are we talking? I think it's pretty insignificant to you and I. Newer cars with the low tension piston rings are burning oil new off the lots. Climate down here in the hot south calls for a heavier oil less prone to thermal breakdown. I try to go no less than a 30 weight oi
Ignore all of this. It's bass ackwards. Another know nothing expert on the internet.

I get you, but what is the reason we are required to run 0w20 here, and the exact same motor is required to use 5w30 in another country? I am not insinuating anything, genuinely curious.

But the fact is the lighter oils ARE worse for wear.
Blanket statements like this are rarely correct.
Indeed.. many people do not realize the base oil viscosity is the lower of the two ratings. The higher viscosity rating is achieved through additives.

You could run amythomg from 0w20 to 15w50 and that engine wouldnt care.
I'd run 0w40 mobil1 in south Louisiana

3.0 Duramax engine?
Edit: posted question before reading the replies.
I had a 3.0 duramax and pretty sure it ran 0w20.

It's about federally mandated fuel economy numbers to auto manufacturers selling their cars in the the U.S. The engine is the same,yes;however, the program or firmware on the ECM that runs the engine is not the same. The difference in MPG'S between the U.S. sold vs foreign sold isn't much but it's enough that it gets the U.S.sellers where they want to be on fuel economy numbers.
I retired three years ago after 40 yrs as a mechanic. I specialized in computer diagnostics and repair on cars.

Sounds like you know it all. Do go on and explain to us what's really going on here

My truck almost burns all of the synthetic 0w20 before hitting 7,500 miles for a change. I always end up having to drop in more right before the change.
Is this because it’s hot garbage, or is my engine going to explode?

So you would advise running the 0w20?
