No it does not, just straight oil into the case.
It will hold approximately 2 quarts. Honda recommends GN4 10W40. A better alternative is Amsoil synthetic 10W40.

No, you don't have to mix gas and oil in a Honda TRX 250EX. The engine is a four - stroke and four - strokes don't need to mix. Two- stroke engines (which are on weedeaters, chainsaws etc.) need to mix oil and usually say in the manual or a sticker on the machine how much oil and how much gas you need.
