Are you sure about this? What I've read indicates Mobil went with an addition of ester to counteract PAOs' tendency to shrink elastomeric seal material. The fact that esters have desirable extreme pressure lubrication properties, too, due to their polar nature on metal surfaces was additional frosting on the cake.

Nope. Terry explained that Redline contains silicon in it's formula, not dirt, but antifoaming. So the 12ppm is not dirt, so it's not causing wear.
1) The current Amsoil 0w-30/5w30/10w-30 formulations are all ACEA A3/B3 rated and have been since the last reformulation. The qt and gallon containers show all the newest ratings - the website is just very slow to post the new spec sheets. The only one that is up to date is the 10w30, but the 0w30 and 5w30 meet all these same specifications. Since they are using a similar additive chemistry, this isn't surprising.
2) The Amsoil 10w-40 has been ACEA A3/B3 rated for the last several years, going back to the previous "SJ" formulation. The formulation works very well in modern gas engines as evidenced by the recent oil analysis results I posted for my Audi TT turbo. I honestly don't expect the xw-30 Amsoil formulations to do significantly better on wear rates or oil degradation. I ended up putting in the Amsoil 10w30 this time, so we'll see how that does.
3) Friction modifiers are normally added to help xw-20 and xw-30 oils meet the energy conserving rating that is part of the GF-3 spec. The xw-40 and xw-50 grades do not have to meet this specification. Typically the addition of an organic friction modifier like moly will provide approx a 1%-1.5% improvement in fuel efficiency.
4) The VI is a function of both the quality of the basestock blend and the VI modifier added. I would not assume that since the VI's of Amsoil are higher than the comparable Mobil 1 grades that they use much more VI modifier. Amsoil uses a high quality, shear resistant VI that I believe is sourced from Royal Dutch Shell - one of their "Shellvis" family of products.
5) The current additive chemistry Amsoil is using in their xw-30 oils DOES use less than 1000 ppm of phosphorus, for folks who angst about such things. I believe they made a conscience decision to do this, since the topic comes up from time to time on various websites.
6) I think Mobil makes very good synthetic lubes, FWIW. If I wasn't using Amsoil I'd probably be running Delvac 1, 5w-40 on a extended drain program.

david:
Is it possible that such a descrepency in prices could be attributed to a difference in oil taxes with respects to US vs Rest of the World?
I'm not sure though, but countries like Canada and the US have their own source of crude oil, whereas most european countries are not as fortunate. Wouldn't this also aid in keeping the prices here lower?
Why do you guys think?

First of all, can someone explain why Mobil's oils are A5/B5 rated and how that differs from the beloved A3?
Where are these other suposedly superior European oils? Europe I know..ha ha. We have a lot of used oil analysis' on here and IMO Mobil 1 is as capable as any. I think certain oils do better in other engines. Technically speaking, yes, Amsoil and Redline are better as they don't follow the API requirments. Plust Mobil is a OTC oil. Mobil formulates and caters to the NA market. Delvac 1 is an example of what they are capable of. I'm sure there 5w-50 is great too, but that is not available here. The reality is, Mobil 1 has shown to do a nice job. Is it the best? NO. I don't know if there is a best. Right now my money would be on Amsoil's S3000 5w30 HD oil.... they should come up with Vegas odds for the best oil for us whackos. Fact is that there is no list that goes on and on with oils that are much better then M1.

John, I realize M1 could be better and I also realize that Terry knows much, much more then I will ever know about oils. Havning said that, I'm sure that Redline is a great oil beyond M1. But M1 does a decent job for the most part.
TS, do the Amsoil S2k, 5w/10w-30's use similar chemistry as you stated? I thought S2k was a bit more advanced?
