Which grease to use?

Hi,

I just purchased a Dewalt grease gun http://ift.tt/1ncRdYv

Only to get it to Australia to find you use different size cartidges over in the US.

So i need to buy some, will a 14oz cartridge fit in the gun that says it is for 14.5oz?

Are either of these two good grease?

We always use Castrol when buying locally.
