A larger earth with the same average density of Earth that has 1.3 Gs of surface gravity would need around twice the fuel to escape into space and a system that could handle that extra fuel and longer burn without self-destructing.

The fuel itself would weigh more, and thus require more fuel to lift. The fuel to lift that fuel would also weigh more and would also require more fuel, etc, and the radius of gravity to escape would also be larger even though it would also be mediated somewhat by the inverse square rule.

I actually wouldn't be surprised if you needed more than twice the rocket fuel to leave a 1.3 G super earth that is 1.3 times it's diameter.

Not impossible, but definitely more difficult.
