I am seeing some good deals on synthetic oils. I drive a 99 Camry with 150k miles. I have always changed my oil every 6 mo/7500 miles using regular oil but would like to try sysnthetic. My friend says I should stick to regular since sysnthetics are "lighter" and would leak more in an old engine. But aren't we comparing oils of the same viscosity?
BTW, there's nothing wrong with my car but it does have small oil leaks here and there that I am willing to live with (I had never had to top off oil between changes).
