New Lower Price for M1 0W-30 ESP

i am going to buy mobil1 0w30 ESP for winter but want to switch to 5w30 for summer.
does it make sense or should i just stay with 0w30 ESP throughout the year?
if I switch to 5w30 for summer, which is a better oil - 5w30 ESP or 5 w30 EP?

Stick with 0w30 ESP...it's claimed by many to be a bit better base oil than the 5w30, and therefore ESP has a bit higher HTHS value. As far as winter goes, there's nearly no difference between a 0wxx and a 5wxx.

I as well found the M1 0W30 ESP very quiet in my Hyundai 2.4L GDI engine .

Is it $27 for 5qts and readily available at any large grocery supermarket store in America?

No thank you, HPL Super Car 0W-30 is better. Amsoil 0W-30 is very thin and will get chewed up even more. HPL will not only not shear, it will also gain a little bit of viscosity.
Looks like Amsoil got chewed up real bad here and then started gaining some viscosity and that also due to bad oxidation thickening. And the thinng still end up at a lower viscosity than virgin. If this had been HPL Super Car 0W-30, it would have gained some viscosity on top of the virgin value of 12.
My HPL Super Car 0W-20 at 11,000 miles will look way better than this Amsoil 0W-30

Plus it is a joke of a 0W-30, too thin. And it is Viscosity Index is over 170 which means it is full of VII's and will get chewed up and lose viscosity real bad.
On the same site, I found this for the 5W-30 ESP. Noack 8.6%. One would have thought that the 5W would have a lower value.
I am not really surprised.
I'm guessing in general, if it was between a 5W-30 and a 10W-30, then 10W would typically have a lower Noack #.
However, once you get into the 0W (e.g. 0W-30) territory, and forced to use a better or more superior base oil (with a naturally higher VI, requiring less vm), then the delta Noack may not be as large relative to their comparable 5W-30 or you can even gain some.
Now once you get into the 0W-40 which requires more vii/light* bases, the delta Noack numbers should be more significant. That's why In general, I prefer 0W-30 over 0W40. Good base oil and narrower spread.
*I have also read that vii have low volatility but it's the light bases used with liberal dose of vii that burns off ... so we have that.
But big picture it doesn't matter what burns off since something is burning off.
btw, everything I said here is in general and relatively speaking ... and I only work here so the management may disagree.

Still $27+ at WM for 5qts of MI ESP 0W30 in sunny Michigan today, while most M1 5qt containers are at $24+. There is a $5 rebate on the M1 website if you download your receipt as proof-of-purchase.
8.6%
"then started gaining some viscosity and that also due to bad oxidation thickening"
Not sure that is a conclusion here. Quite the statement. Based on Blackstone even. Interesting. I mean are Blackstone's range values even correct? No. Show me the "bad oxidation thickening" for example.
Stick with the M1 0w30 ESP
He’s just making stuff up in those posts.
You do realize Amsoil has high virgin oxidation due to the use of ester?
