is it normal to have to add oil every few rides to the turbo oil res? i know it says only 16 0z but i get nervous not being able to check it with only 16oz in there because it so far down in the res, so i have been filling it up just a little more so i can touch it with my finger. But like i said every few rides its way back down and i have to add some... also when i park the sled in the garage to melt off the water dripping out of the bottom from the turbo side is oily, as is the side panel. I have looked high and low trying to find a leak. any ideas? its an o9 BD turbo M8
