Title: Dura Lube is still the best
Review: I first came across Dura Lube twelve years ago, while living on the east coast. And it does what it says; in cold starts, the car would start fresh, as if it was warmed up. Anyone who lives in a cold climate knows that grinding sound as the cold oil washes back up into the engine, and how that means a shorter engine life. And while I am currently in California, I use DuraLube still. I hear the difference, and since my 2004 Toyota Solara (Which has been great, no problems) has 150k miles on it, I am convinced Dura Lube is a winner. Highly recommend, and I have nothing to do with the company. [...]
