Thanks, yes, it's there.
Comparing Ultra to Platinum, is it worth the extra ~$3 per 5 litres, in your opinion?
It's ever so slightly thicker, 48/8.8, vs 46.3/8.6 for the Platinum, and they have similar flashpoints now. What other differences are there, or might there be, if you don't know for sure, between the current Ultra and Platinum in 0W-20?
As for the Ultra SN to SN PLUS, from the Canadian PDSs, the only change seems to be the flashpoint, which went from 224C (D93) to 208C (D93).
As for the Platinum, via epc.shell.com,
__'German' 'Shell Helix Ultra SN PLUS 0W-20' (

has the same numbers as,
__'Canadian' 'Pennzoil Platinum SN PLUS 0W-20' (
https://www.shell-livedocs.com/data/published/en-CA/47ee9a21-8068-4328-9444-a38578a240cc.pdf),
except the flashpoint is D92 in the German PDS, and D93 in the Canadian one.. the actual flashpoint number is the same though... coincidence, or mistake? Are those two actually the same oil??
Also, the Canadian 'Pennzoil Platinum SN PLUS 0W-20' I got at Canadian Tire today (April 2019 on the jug) doesn't have HTO-06 on the back, but the PDS (01.29.2019) has it. Mistake in the PDS? hmmmm
