I need help !

Hi guys, I need help with cooling and oil, but seriously, I'm having to use Lagafruta plants and they're barely growing. Luckily, I have an anti-entropic thermo-nullifier on the side of the base (in the center) and can someone explain to me what oil is for besides energy and plastic? Thanks.
