Do you need to mix gas and oil for a Honda trx250ex ATV?
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.
