The present invention is a lubricant or functional fluid additive for a polyolefin oil blend, comprising a mixture of: an anti-wear component consisting essentially of 95% isopropylated triarylphosphate and 5% dodecyl phosphate, the dodecyl phosphate being only partially esterified, the anti-wear component present in the polyolefin oil blend in a range of from about 0. The folder can have a low profile in which the axes of various elements and assemblies in the folder are located within height ranges relative to the height of a folding roll axis in the folder. The processing biases are then truncated. Ions are accelerated in accordance with this gradient. These peroxides provide a long-term oxygen reservoir, releasing oxygen relatively slowly over time.
