Wife's gotten vehicles from Enterprise with 3/8 tank, they say oh just bring it back with 3/8.
Not sure if they just don't care because she has a corporate account or what. I think "internal use" like shuttling the cars around, letting employees take them home etc, is the reason for lower than full gas.
I think it's because the majority of renters, attempting to return the car with "at least" as much fuel as it left with will end up returning it with more. That's a small plus for Enterprise and those little pluses add up. I do not like it.
