Here in Australia we have a star rating system for whitegoods. The more stars, the less average energy use per annum.
Just looking at the instantaneous current draw while the motor is running doesn't really tell you anything.
If it was a choice between 1.1 amps for 12 hours a day, or 5 amps for 1 hour a day, I know which I'd rather have.
Not saying that adding cap's won't improve the situation, because I honestly don't know the answer to that one.

See if that fridge has a wattage rating as well as the current draw. If it has a much higher wattage rating than the others, then it has a bigger motor as Commanda suggests.
If there is no starting capacitor it is either hi-tech and probably good, or just plain crude with resistance phase shift and just cheap and cheerful. In these days of concern over energy consumption I hope it hi-tech.
Careful use of power factor correction can be an advantage, but watch it with modified square (sine) wave inverters.
