The Wolf's Head 100% SYN 5W30 mentioned a synthetic base stock...I believe both the SYN and the HD 5W30s are ACEA A5/B5 rated, unless I read that wrong. I've been well pleased w/ the PP, the M1 0W30 seems good - nice & quiet like the PP at least - but I thought it was time for a change & wanted to be different.

Almost decided to go with Amalie oil because I know it's "Better than it has to be" ...but I finally decided upon the Wolf's Head because it's "The finest of the fine since 1879"

M1 Supersyn Antiwear Technology
This is a Polyol TME

Polyol esters have lower coefficients of friction than either diesters or PAO's.

By adding a polyol ester at least 5-10% to a PAO or mineral oil reduces base oil friction remarkably. So esters are natural Friction Modifiers.
