Chevron PDS has some info but not everything

Well in general, the 5W-30 (XSP) synthetic will be better for extreme cold weather starting and fuel economy (had to state the obvious).
I think Chevron claims XLE can provide up to 1% better economy compared to 15W-40 and XSP can improve FE by up to 2% over 15W-40.
They both have the latest (North American) HD diesel approvals and are CK-4/SN Plus. The odd thing is that the synthetic doesn't have the latest Renault spec (RLD-4), but XLE does. I don't know anything about that spec.
The synthetic XSP has the toughest Deutz spec (DQC IV-10LA), XLE is one notch below that (DQC III-10LA).
Both oils are capable of very long OCIs, but it comes down to cold weather needs and pricing, I guess.
Thank you for the info
I'm doing an OC in a couple of days, switching out QSUD
5W-30 to the Delo XSP 5W-30 almost went with the 5W-40 but thought not right now.
