Shell Helix Ultra 5W40 is good stuff and one of the best oils made by Shell / SOPUS. It's a GTL full synthetic and full SAPS, just look at the OEM specs it carries: API SN, ACEA A3/B4, VW 502/505, BMW LL-01, MB 229.5, Porsche A40 and Ferrari approved. You don't get all those factory approvals unless you make a good oil.
The SHU 5W40 is very common in Australia and Europe, but much less common in North America where Pennzoil Platinum Euro 5W40 would be the equivalent product (or very close).
The ACEA and OEM specs above requires a HTHS > 3.5 cP, TBN > 10 for long drain intervals and Noack Volatility < 10%. All good stuff.
