As a general rule, feeding oil is always going to be more economical than a powdered fat supplement, because as Simkie noted, they’re both 100% fat, but an oil is more dense that a powder, so you’re going to need a greater volume of the powder to get the same calories as an oil.
Using Absolut’s math, and assuming that the scoop is 2oz by weight (everyone is selling the 8lb bag as a 64 day supply, which would be 2oz per day, so I will carry on with this assumption), 7.84 scoops (2oz each) of Cool Calories = 1 cup corn oil:
1 cup corn oil = 7.63 oz BY WEIGHT = 1950-2000 calories
7.84 scoops (2oz) CC100 = 15.68-16 oz by weight = 1950-2000 calories
So, to get the same number of calories, you need to use a little more than double the weight of CC100 to get the same calorie content as oil.
Which means that roughly 1 lb of CC100 is equivalent to a little more than a CUP of oil. So to get the same benefit as a cup of oil per day, you’d be feeding a pound of CC100. YIKES.
For me, adding oil will always be preferable where possible, because its SO much cheaper, even if you go for the more expensive/better oils (cocosoya!!) over plain old corn oil. Powders are good for picky eaters that won’t take oil, or people who live in extreme climates and don’t have a temp controlled area to store oil so it doesn’t freeze in the cold or go rancid in the heat.
