answer simple. for lubrication
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.
A 2-stroke engine requires adding 2-cycle oil with the gasoline.
It depends if it is a 2 stroke or a 4 stroke. A 2 stroke engine, you mix the gas and oil. A 4 stroke engine, there are separate tanks for the oil and gas.
Usually no.
With a 2 stroke engine, you mix the oil with the gas. With a 4 stroke engine, there are separate tanks for the oil, and the gas.
No, you don't mix oil into the gas of a Polaris Trail Boss 350 4-stroke. It is a 4-stroke engine, and you do notmix oil with the gas.
buy garden engine oil from Halfords then follow your manual instructions for a mix
Usually none at all.

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.
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.
