I was working on my polaris and I noticed on my crank case an oil fill plug and it says " 15cc of oil, I am not sure what kind of oil to put in here, it is a 2 stroke oil injected motor and I did not know that it needed oil in the crank case, can someone fill me in on this
Thank you

That is your counterbalance and it is the most important thing on a 400 to keep changed

 

Maybe I did not give you enough info, this is a trail boss 350 liquid cooled 2x4, I just want to know what kind of oil to put in the crank case, I didn't think I had to put oil in the crank case on a 2 cycle engine, but on the crankcase cover it says 15cc oil with an arrow pointing to a plug (not on the drain plug)

10w30 in the counterbalance fill the oil tank with 2stroke oil

 

just changed all my fluids last night....Counterbalance is a pain...get yourself a manual it helps.

 

Thanks for the info
I removed the drain plug beside the recoil,but nothing came out, is this the right drainplug (looks like 10mm bolt)?

Also, do I only put in 15cc of oil

that was the recoil drain plug probably you really need a manual there are 3 drains under there. the one in the middle of the motor is the counterbalance drain atleast mine is. oh yeah its 10mm with a philips slot in it,
