the advantage diesel pickup trucks have is that they have been around for a while, the technology has been proven, and they are cheaper. The disadvantage is the gas mileage. Compare and decide for yourself.

While 8 cylinder trucks bring more horsepower and durability, 6 cyclinder diesel wins hands down. Diesel trucks are more fuel efficient, and with diesel mpgs run circles around standard gas trucks. so if i were you id go 6 cylinder diesel

no diesel is used in trucks. like buses or truck driving trucks
