Valvoline also came out with a "Max Life" motor oil that supposedly benefits older engines. They claim it reduces oil consumption in engines with fatigued valve stem seals. I'm not sure I understand how a lubricant can be modified to reduce it's getting past worn seals? Sounds a little like the hair shampoo commercial that claimed "it only gets to where it needs to be".

Sorry for getting side-tracked, but I'd be interested in knowing how Valvoline has suddenly come up with better potions for older engines, trannies, etc.

Who knows? Maybe they have.
