(1) Add only water if the mixture reduces in amount
by evaporation.
(2) If there is a mixture leak, add the LLC of the same
manufacturer and type in the same mixture
percentage.

manufacturer. (Different brands may have
different additive components, and the engine

adversely affecting the engine parts.
