[General Zombies] Do Zombies gain a supernatural ability to resist the effects of entropy?

I'm not sure how else to explain their longevity and resistance to break down when faced with months, if not years without fuel.

It's not so much that they gain resistance to the effects of entropy, it's that none of the bacteria and insects that would normally break down decaying matter want anything to do with it. Think about a slab of beef in your freezer, it's not exactly decomposing as fast as it would if you left it outside in the summer heat. 

That's not to say they don't break down over time, just not from decomposition. Eventually a zombie that has wandered for long enough or been degraded by the elements enough will have decayed far beyond the point they were at when they first turned and will eventually break down into crawlers and eventually immobile moaning husks. This decay isn't from outside organic processes but merely the breakdown of muscle and connective tissue from repeated use without the ability to rest or repair and extreme exposure to extreme weather conditions, or even such actions as wandering through brush or taking a fall.
