High grade true polymer lubricants that have been in use for these purposes are very expensive, as much as $50 per litre, and therefore have not been cost effective for everyday transportation use.
This high cost is why most Synthetic Oils that claim they use PAO's only use a very small amount of P.A.O’s as a marketing tool and use less expensive Esters, additives, petroleum oil carriers or a blend of these for the balance of their product.
Motrlube, however, with its significant advanced technology, uses a pure PAO base stock and an additive blend that displays the same characteristics of a true PAO, at 1/4 of the cost.
A totally PAO based class of lubricant within reach of all consumers.
