Would not a 5w-40 achieve the same results with a bit less Vll needed? Or is the 5w-40 a "lesser quality" oil?
Can I use 0w40?

I was actually looking for a good 5W-40 for the 3.3L in the Santa Fe. If you can recommend something that is actually better than M1 / Castrol 0W-40 I would give it a try
Castrol Edge 5W40 is lesser product compared to Castrol Edge 0W40 or Mobil1 0W40.
You really do not need to look , but of readily available products Pennzoil Platinum Euro 5W40 is in the same league with Edge 0W40 or Mobil1 0W40.I was actually looking for a good 5W-40 for the 3.3L in the Santa Fe.

Can I switch to a 0w40 A3B4 oil like Mobil1 FS 0w40, from using a syn 5w30 like Mobil 1 in all my engines? After reading this thread it seems like (somewhat?) reasonable question.
I now use the 0w40 in my 2019 MB GLC300. My reason to switch is ONLY to stock only one viscosity in my garage. Equal cost at AAP.
Other engines:
1996 Toyota Camry Camry 5S-FE
2007 Honda Civic SI K20Z3
2018 Cummins whole house natural gas generator
2004 Ariens snow thrower with Tecumseh L (not OHV)
2019 Honda walk behind mower
1999 (for y2k) Powermate 5KW generator with B&S Vanguard OHV engine
Thanks

Of course. It’s exactly what I usually do.
Exactly how is this so? They have same approvals..
Simply looking at data.
Debated here a lot. You can look for it.
While oils can have same approvals, approvals set up minimum requirements, not maximum. That means that among oils approved for same specifications, you will have those that meet bare minimum (Edge 5W40) or those that go further (M1 0W40 or Castrol 0W40 for example).
How? If their "EDGE" is on the edge of what they can offer?
I would always choose 5Wxy over 0Wxy....unless I would live somewhere in Alaska (or similar)...
Less VI...less chemistry...more stabe...stay in grade...etc

Higher Noack: 11% compared to 9.1%
Higher KV100 but same HTHS (3.7).
Viscosity Index 0W40: 181
Viscosity Index 5W40: 187.
No, 5W40 is not on the Edge of what they can offer.

In this case, far cheaper base oil selection, more volatile, as edyvw noted...etc.
MB 229.5?
Yep. Some MB229.5 oils have bit higher Noack than 10%. Why? MB's right to do so I guess.
So, you have 5W40 oil with 11% Noack and 0W40 oil with 9.1% Noack. That tells you enough about these two oils that cost same amount of money. So, which one would you get if buying?
Yep. 5W40 is 100% HC oil. Considering that pour point of 0W40 is -60, it is probably right at 50% PAO.
Though -45 pour point in 5W40 is testament of quality HC base.
I just looked at 5w40 on Castrol website. It doesn't show noack or HTHS. So where did you find your figures?
They were done by other sources. It is here somewhere in the threads. Numerous about this Castrol, so look for it.
I was searching for answers the other day and came across this thread., it convinced me.
Castrol 5w40 vs Castrol 0w40
I see a lot of people praising Castrol's 0w40 on here but I never see anyone talking about their 5w40 at all, is it really that inferior? My local Costco carries the 5L jug of 5w40 for $32 CDN, although it's still cheaper for me to buy Castrol 0w40 across the border in a US Walmart. So what is...
