kütusele
Kütusele is the allative singular form of the Estonian noun kütus, meaning fuel. In Estonian grammar, the allative case marks direction toward a place or object or the target of an action, rather than possession or quantity. Kütusele is used primarily in contexts that involve movement, transfer, or allocation related to fuel, and it appears in technical, logistical, and infrastructure-related language.
The allative form has a plural counterpart, kütustele. It is distinct from other cases of kütus: kütuse
In typical texts, kütusele may appear in phrases describing operations such as delivering fuel to a tank
