Why is the price higher the greater the viscosity of the base oil?

That can’t be right; rarity makes something valuable
It can be understood that the higher the viscosity, the more difficult hydrogenation is. Both temperature and pressure have increased, electricity costs have gone up as well, and it also affects the lifespan of the catalysts: lol
