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.

What is the oil gas mixture for a push lawn mower?

most new push mowers use just regular pump gas. if the engine has a place to check engine oil and has it own oil and filter it is a 4 stroke engine and does not require mix gas. A small engine that requires mix gas (2 stroke) it will be in a 1:25, 1:30, or 1:50 mix of oil and gas. most newer 2-stroke engines use a 1:50 MIX. Look on the fuel cap or see if it is stamped on the engine anywhere. You may need to contact a manufracture to be sure of the mix ratio.


Do 47cc Pocket bikes need oil changes?

No. Because the engine is a two stroke. Make sure the engine is a two stroke though. If it is a tiny engine with 1 gear and a pull starter and makes a high pitch sound it is probably a two stroke. Consult your owners manuel or the manufacturer of the bike to see if it is a two stroke or four stroke engine. You will have to change the oil if it is a four stroke, but I think most 47 and not 49 cc bikes are two stroke. If it is a two stroke, no oil changes are required, but you will need to mix a certain amount of 2 stroke engine oil with the fuel. Your owners manuel or manufacturer should be able to tell you the ratio per gallon of gas you will need. Hopefully, this will help.
