I drive a Chevy 1Ton it has 329,433 miles on it. This past week it ran hot on me, by the time I could get it off the road the temperture had gotten over 280 degrees. When the heads were pulled off of it they had cracked bothsides. Looking at the inside of the motor (It was as clean as a new motor). There was not even a ring grove on clyinder walls. I work for a company that drills under roads. I use Lucas in all of our gearboxes. I would not use anything but Lucas.
