Examining that premise, it seems you are looking at the certain ( very small in total terms ) gain of fuel and rations used, against the potentially huge gain of destroying lots of strategic equipment, which could disappear under some circumstances ( bridges repaired, increased protective patrolling ) and further severely disrupting any possibility of advancing. For me that's a terrible evaluation of risk/return.
