I was told by a friend long time ago that if I ever have a power steering leak, not to use one of stop-leak additives, as it would only be a temporary fix and the leak will eventually get much worse.
So ever since the high mileage-type oil first came out I wondered if the same thing would apply. Now, I found at Mobil 1 website also states something along that line, "ExxonMobil engineers are wary of conventional oils that tout their use of additional seal-swelling agents. With extended use, these agents can over-soften engine seals, resulting in leaks."
It maybe too early to tell, since the oil only been on the market for a few years, but do you guys think high mileage oil can eventually cause early leaks in otherwise well mantained vehicles?
I'm kind of leery of using all those free MaxLife in my cars that have moderate mileage but no leaks.
