Thanks. Clears thing up a bit.

Looks like your guess was better than mine.

The note at lower right is a bit unsettling though.

Judging from the Lubrizol comparison tool fuel efficient beats aftertreatment compatibility in Ford vs ACEA C sequence comparison.

Either ash is not critical to the life of Ford DPF or Ford deemed it best to sacrifice DPF life for fuel efficiency or they plain forgot?
