Spook Juice vs. Moonshine

[Victor]

We hit a game stopping debate in our Hell on Earth Campaign.

Spook Juice costs $20 and comes in 1 gallon increments, with a weight of 6.

Moonshine costs $10 and does not say the container size but does have a weight of 4. It also gets half the mpg of spook juice.

We assumed the Moonshine was also a gallon, our GM thinks it should be the size of 'a bottle of booze" which is 1/5 gallon.
We can not use the spook juice without making a new PC.
I know there is nothing official, but I wouldn't mind some opinions on this.

Logically (based on weight) it would be 2/3 of a gallon, assuming the same container.

Easier option would be to say they are both a 1 gallon, but the spook juice is stored in a 2 lb. jerry can, whilst moonshine is in a less than 1 lb. lightweight plastic container.

I'd go with the second option in my game to be honest.

If both Spook Juice and Moonshine weight the same in a one gallon container then it would be safe to assume that moonshine would cost 15/Gal
