ENGINES OVERVIEW
The International Harvester 756 features a robust 5.1L 6-cylinder diesel engine, offering higher torque and fuel efficiency compared to the 4.8L 6-cylinder gasoline variant, making it ideal for heavy-duty applications like plowing and towing. The diesel option typically provides reduced operational costs over time, though initial purchase prices may be higher. In contrast, the gasoline engine offers easier starting in cold weather but generally less power for demanding tasks.
