I like 5W20, I may try it in '00 MB E430, it requires A3/B3 synthetic oils. HT/HS of 5W20 is 3.3 which is almost 3.5, also flash point is very high at 251°C.

I've thought the same thing. I have about 9000 miles on the M1 in my Camry and have decided to give SSO a try for the winter. This will be my first experience with an Amsoil product other than their EA oil and air filters. BTW, while the relationship is not linear or predictive in terms of percentage, there is a correlation between base stock composition and flash point.

Look at the HTHS delta between the 0W30 and 0W40; it's about 0.8. The delta between 0W20 and 5W20 is only slighty less.
The flash points are lower and the volatilities are higher for the 0W weights because the starting weights for these oils is lower. Generally, for lower weight oils, the majority oil is a a 3.4 to 4 cSt and a few percentage of heavy weight is added for stability. You need this to get the low pour ponts.
Generally speaking, any Noack 11% or lower and flash point of 375 F or higher is good.

Another factor is that possibly RL is using a larger percentage of PAO for the lighter weights.
Various new polymer chemistries including PAO polymers (not VII's) can give quite a good UOA showing.
Let's see some used oil analysis before we second guess their performance.
Recall that a few years ago many thought Motorcraft 5W20 and other 5W20's could never give good anti-wear performance, but chemistries have changed for the better.

Amazing pour point but where are the MRV values?
Still going to stick to Esso XD3 this winter.

Also wondering where you got these values? They don't seem to be listed on their website quite yet.
Where did you find the Noack values ? Flash Points are listed but no Noack.
so their 5w-20 has better HTHS then new 0w30 meaning 20 wt will protect better then 30?

Ok, what are Noack and HTHS?
buster,
When did this oil come to be?
I am a Prime customer with Amazon (well worth the cost) and shipping on products that Amazon sells is free.
For what reason I do not know, Amazon has always sold Redline Oil ..... Valvoline as well. That is to say it stocked and shipped via Amazon, not a third part as is the case with most of this type of product on Amazon.
I ask because I do not see this product available via Amazon.

No. You can't conclude that based on just that spec.
Engine wear is highly correlated to HTHS value from what I know and according to this article that mentions BITOG as well:
HTHS - Bob Is The Oil Guy: "A jump in HTHS by about +1.5 results in approximately 1/5 the wear. Now this relationship is not linear and flattens as one nears a 40+ weight oil."
...
"Summary: It was found that HTHS correlates better with wear values found in actual oil analysis and actual tear-down measurements than does measuring the oil film thickness in situ."

Just started using the 0W20 in a 2009 Camry. Engine was quieter on start up. Last trip [500 miles] mpg = 34.0
