Yes of course. Lots of different versions from all manufactures and in different countries too.

Yes I like Moly, and many oils and some assembly lubs contain it. And yes a real breaking-in oil is not designed for long term use. And yes assembly lubes are used on engines.
However not all Racing Oils or Breaking-In oils are heavy in Moly.
Penrite 10-Tenths Racing oil (PAO & Ester) claims Zn 1760 ppm, Boron 630ppm and Moly 100ppm.
Penrite Running-In oil (mineral) claims Zinc at 1610ppm, and no Moly. It also says "non friction modified, low detergent & dispersant engine oil, designed for the critical running in period ", so not normal detergent levels from Penrite. Not saying what you describe doesn't exist, I'm sure it does, just saying it's not the only way of doing things.
Here is a link for anybody that wishes to read some more.

Anyway, that's all going off on a tangent above. All I was doing, is just commenting that this is another 5W30 A3/B4 oil (with other OEM specs) that is also API SL (not SN), just like the Castrol Edge 5W30 A3/B4 is in Australia. So my local Edge isn't the odd one out.
To the OP, thanks for posting, yes I did find it interesting. I like Shell GTL oils, and I wish we got this one in Australia.
