Largest HD OEM’s (Daimler, MAN, DAF) recommend ACEA E6 10W40 HDDEO
(source: ACEA)
Mid- and high tier HDDEO suitable for API group II rerefined base oil performance.
As a European pioneer, Puralube already completed parts of these test programs.
EcoStream to follow suit by end of 2013 / early 2014.

Crude refineries manage C1 – C500 range
Rerefineries focus on C20 – C40 molecules
Both feedstocks black, value determined by yields
Average base oil yield from crude:
~ 1%
Base oil yield from used lubricant oils: up to 70%
