Which advantage does dual fuel operation give an operator?

  • A.The ability to run on diesel when gas is unavailable
  • B.Nothing, since the engine requires both fuels simultaneously and cannot therefore operate upon either alone
  • C.Only cost
  • D.Fallback to diesel operation where the gas supply is unavailable, which removes the refuelling constraint

Answer: A

Falling back to diesel removes the infrastructure constraint. The last option explains exactly that benefit, which makes it a correct and more instructive version of the same answer. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Naming what changes and what stays the same is the reliable route through questions of this shape.
