It is GTL-based (50–60%) now. It used to have only 10–20% PAO and 20–30% GTL. Note that around 15–20% is reserved for the add pack and VII.Maybe not but both AFE applications have a higher pour point (-42) then I'd like in a 0W oil so they've taken most of the PAO out of them. There just seem like better options for the money...
Which nonboutique oil uses PAO these days?
