Isuzu Commercial Truck of America will cover all scheduled maintenance for two years or 60,000 miles, whichever comes first, on new Isuzu N-Series diesel trucks sold during the program period of Oct. 1—Dec. 31, 2013. The 24/60 Covered Maintenance Program includes an initial “dry” inspection service at 4,000 miles, followed by six additional maintenance services beginning at 10,000 miles. It’s the latest example of the company’s commitment to drive down operating costs, said Isuzu’s Shaun Skinner.
