Mobil HTHS Data ?

Has anyone obtained the HTHS data on the entire Mobil Supersyn line of oils and also the MX4T 10/40 and V-Twin 20/50 that they can post ?
I think it can be inferred from the ACEA ratings on the automotive line. The xW-30 oils are rated A5 which is 2.9-3.5 mPa.s, and the 0W-40 and 15W-50 oils are rated A3 which is >3.5. Ken
Mobils data showed the 0w-40 to come in @ 3.6 Cp and I saw some data on the 15w-50 Tri-synthetic that showed a value of approx 5.0 for that formulation. The 0w-30/5w-30/10w-30 are about where there were with the trisyn, in the 3.0 Cp to 3.2 Cp range. You can get a pretty good idea of the HT/HS by looking at the kinematic or low shear rate viscosity @ 100C: 9.5-10.5 Cst @ 100C--3.0-3.3 Most xw-30 "energy conserving formulations sold in the US fall in this range 11-12 Cst @ 100C ----3.5-3.7 14 Cst @ 100C =------3.6-3.9 15-16 Cst @ 100C-----4.1-4.3 Most 15w-40's are in that range 18-20 Cst @ 100C-----4.8-5.2 A 5w-50 is going to be at the low end and a 20w-50 at the high end.
The older CH-4 version of Delvac 1 came in @ 4.1 Cp @ 150C. I would expect the CI-4 stuff to be the same, since the kinematic viscosity @ 100C hasn't really changed. D1 is probably the most versatile stuff they make ...
