neither,the yz250f is a four cycle bike...
No its pre mixed only
An Oil Injected motor will have a separate Oil Resevoir, so mixing Oil and Gas is not required, and in fact inadvisable.
unleaded
SAE 10w30 oil.
the main difference is a two stroke has oil mixed into the gas weather it is oil injected or pre mixed(adding oil to gas yourself). a two stroke has no intake or exhaust valves,no pushrods,or rockerarms. intake and exhaust into the combustion chamber in done through the sides of the cyllinder walls.
It should be oil injected with a separate oil resivoir.
yes it is supposed to be in there
oil is injected, it has separate oil resivor from the gas tank just fill it up with 2 stroke oil and go...
no
The YZ250F holds three pints of motor oil. The manufacturer recommends that you never overfill the oil reservoir, nor allow it to get more than one half pint low .
actually I think that model has a small tank under the seat if so its oil injected that's a whole different kind of oil. That's oil injected oil no mixing
The older two-stroke engines DO require mixed gas and oil, but the newer four-stroke engines use separate gas and oil. Which do you have?
