For vehicles with higher milage, does anyone have experience using products like Max Life from Valvoline? I don't have leaks and the engine is mechanically sound, so I'm not sure if a product like "Max Life" is really necessary. I'm already running a full synthetic with no concerns. Besides, I think most higher milage oils are semi-synths anyway.
I'm looking for a high quality full sythnthetic that won't rob my seals of needed conditioner as the engine ages. Any ideas?
