① Different output: T63 has 3 cavities, T80 has 4 cavities;
② Different structure: T63 is of "C" type, and T80 is of "H" type (H type has better stability, and it is recommended to choose T80 if the budget allows);
③ Different oil usage: T63 requires lithium-based ester, while T80 does not, and its oil circuit is closed (cleaner and more fuel-efficient).
