For 31 HP Daihatsu Gas Units:
For best results use only clean, fresh regular grade unleaded gasoline with an
octane rating of 87 or higher. Regular grade leaded gasoline may also be used;

service. See Engine Owner's Manual.
For 27 HP Daihatsu Diesel Units:
For best results use only clean, fresh diesel fuel, with a cetane rating of 40 higher.
