How does all that
GUNK on the outside of your car break down your motor oil faster?
I stick with Mobile 1, I can buy it anywhere, and since I'ce started using it my car runs smoother, a little quieter (maybe it's in my head, who knows?), but noticabe difference is that the temp guage is lower than when I was using Penzoil.
