A MILLION MILES YOUNG Any number of GMC coaches powered with General Motors Diesel engines have passed the million-mile mark. And they're still going strong. Still pulling upgrades smoother-still faster on the get-away-still turning in upwards of 50% more miles per gallon of low-cost fuel. One reason is the GM "71" 2 - cycle Diesel engine that packs big, tough horsepower into small space and light weight. Coaches are just one example. These sturdy power plants hand out performance like this everywhere they're used-in tractors, boats, trucks, cranes-driving oil-well machinery, lumber saws and cotton gins. All through the war GM Diesels have been working side by side with our fighting men, powering landing craft, tanks, tractor bulldozers and all kinds of hard-working machinery. And as these boys come home, these engines will still stand ready to work side by side with them-ready to provide rugged, long-life, low-cost, easily maintained power in the countless ap plications of America's expanding industry.
