Narrator: State trooper cars put on top of mileage but sometimes your car puts on top mileage too just like a trooper's. That's why you should use Texaco's Havoline super premium motor oil. Since 1972, more than 90 trooper cars using Texaco's Havoline were driven a total of over 4 million miles. Of the engines taken apart, none showed any sign of unusual wear. With Havoline's balanced formulation you can get all this protection without buying any extra motor oil additives.
