quote:It's not done with PPDs, since PAOs and esters don't respond to PPDs. I'd say it's primarily the high natural viscosity index of the base oil blend. What you've got with these oils is an extremely thermally stable base oil blend, one that has excellent low temp flow characteristics, but doesn't thin out at high temps. Remember, a high VI means a high resistence to change in viscosity with temp change. This translates into a base oil blend that doesn't thicken up in cold temps and doesn't thin out in high temps.
Originally posted by Patman: In looking closely at the specs for 0w40 Mobil 1 in comparison to their 5w30, I wonder how it's even possible for them to create this oil. Their 0w40 is considerably thicker at 40c, it's 80.3cst vs 53.7 for the 5w30. So if it's that much thicker at 40c, how can it flow so much better at cold temps to be a 0w oil? Is the base oil that radically different, and if so, how? Or is it all done with pour point depressants?

quote:Mobil's "European Formula" is just a marketing slogan for the 0w-40 oil sold in the US. From what I know, very few people run this oil grade in Europe. There is a 5w-50 Mobil oil that I know many people over there use. Castrol also sells a 10w-60 oil there - another popular one. So, as you can see, the viscosity spread out there is even higher than what we're used to here in North America.
Originally posted by buster: I find this particular visc. strange. Mobil claims to make the most common and applicable viscosities but a 0w-40 is just too much of a spread IMO. 0w is the future of oils, but why this weight is so popular in Europe surprises me. I'd rather run a 0w-30 in winter and 10w-40 in summer. I wish Mobil made a 10w-40, as it would most likely stay in grade.
quote:This is not just a marketing slogan. Mobil 1 0w40 comes as factory fill in every Mercedes AMG model, every Porsche, and every Aston Martin. In addition, it is the only oil currently made by anyone that carries the most severe performance ratings from both the US (API) and Europe (ACEA). It also meets the toughest OEM oil spec, Mercedes Benz's 229.5. This is very much a "European Formula." If you check out the major European oil web sites, you'll see that they all feature 0w40 as their "premier" oils. Castrol makes their Formula RS in 0w40. Shell now sells their Helix Ultra in 0w40. Motul's top-of-the-line oil is 0w40.

quote:As I've said before, I suspect that Mobil has decided to keep the price point of the 0wXX oils in line with the other grades even though they are more expensive to make. This lowers their profit margin on those oils, but it increases the chances that people will purchase these "new" grades and use them.
Originally posted by Patman: I guess I'm just wondering how Mobil 1 creates their 0w40. They don't charge a lot more $$$ for it, so it's hard to imagine their base oil could be so much better in the 0w40.

Why do I have an image of Mel Gibson's Mad Max in my head. Do you remember the one with the ultra light pilot? Probably because I've never been to Oz.
On a serious note, I would love to take a vacation down there. I hear it is a great place. I'll need a steady job first, though.

Now, 0Ws are becoming more common there as well, as oil technology improves. As mentioned in other threads, 10W-40 has a very bad reputation here in the US. I'm sure that's why Mobil (& others?) market their latest HDD oils as 15W-40, even though they meet the 10W specs. In N/A engines, I think any of Mobil's 40wts (M1, D1, & D1300S) will stay in grade.
