The Castrol Australia web page now features Edge 10W-30, which wasn't there last time I looked. I'm very excited, I've been looking for a full synthetic 10W-30 oil for awhile. Before this turned up, the only synthetic Castrol 30 weight oil we had was the Edge 5W-30 A3/B4. This new Edge 10W-30 is an ILSAC oil, but their PDS sheet was very slim on details, so I rang Castrol up and asked them for HTHS & TBN, and they told me real numbers !!
The details are below, both for 10W-30 and 5W-30 Edge, for comparison.
Edge 10W-30 (API SN, ACEA A5/B5, ILSAC GF-5)
Vis 40C = 66.2
Vis 100C = 10.47
Pour Point = -36C
TBN = 11.2
HTHS = 3.2
Edge 5W-30 A3/B4 (API SL, ACEA A3/B4, BMW LL-01, MB 229.5) (Note Castrols says: "Passes all engine test performance requirements for API SN and SM but exceeds Phosphorus limits for those classifications.")
Vis 40C = 71.8
Vis 100C = 12.0
Pour Point = -36C
TBN = 10.2
HTHS = 3.6
I also rang around a few shops to see if I could find the 10W-30 Edge.
SuperCheapAuto (SCA) - not in stock and no idea
Repco - not in stock now, but they expect it soon
AutoBarn - not in stock now, but they can order it in and get it in about a week. The price is $60 for 5L for the 10W-30 (note the 5W-30 costs about $70 for 5L, normal retail in Oz).
And just for completeness, I can now get imported Kendall full synthetic GT-1 10W-30, it's details are
Kendall GT-1 10W-30 full synthetic ( SN, GF-5)
Vis 40C = 63.2
Vis 100C = 10.4
Pour Point = -39C
TBN = 8.0
HTHS = 3.1
All three of the above oils should contain Titanium additive, as well as the normal Zinc.
