fill up the gas (?)

Hello,

I have a question on an expression “fill up the gas”.

As you might know, it is an expression that can be used at a gas station. Do you think this is a correct one? It is on my English book, but I think it sounds a bit odd.

Instead, I think these expressions below are right:

fill up “with” the gas
or fill up the gas “tank”

I guess it might be used in spoken language. However, I do not think it is grammatically correct. As far as I know, “fill up” should be followed by a container such as a tank or something that has one, like a car. To take the gas as an objective and sound right, “with” should be used.

Thank you in advance,
sweetpumpkin

The sentence “fill up the gas” should mean ‘fill up the gas-tank’ wherein ‘tank’ is implied.
