Motorcraft vel Ford Formula F 5w30 is made by Castrol at least in some EU countries. Castrol Poland confirmed that to one Ford forum user here. Heard that Elf/Total makes it for France, spain, Portugal, but thats unconfirmed. So thats just a licence to major players with a given spec.
Wondering if spec is worldwide or also market dependant. Below is formula f 5w30 spec:
Base: synthetic "technology", so hydrocrack
A1/B1
VI 160,00
HTHS 3,00
Ash% 1,30
TBN 9,00

Cst@100C 9,6
