the only oil you need in that machine is the mixing oil and then you also have gear lube..

 

You do have to add a small amount of counterbalance oil to the 400's. Only about 2-3 oz.

 

what kind of oil are we talkin here?

 

If you remove your filter box there is a dipstick that unscrews. It is below and behind the carb and has a large slot in it for a standard screwdriver. Just use regular 10w30 motor oil in there about 2-3 ozs. The drain for the counterbalance is in front,lower, right corner of engine and has a 9/16" head on it. Don't forget about the crankcase and starter pinion drains these are on bottom of engine in recess by starter motor, you have to remove the skidplate to access these. HTH
