What's typical oil consumption like for the (tc88) engine. Had to top off the motor and transmission a couple of times during this summer's trip (5000+ miles). However, since we were running 2up and loaded, cruising at 75-80 ish, it didn't seem like anything to be too alarmed over. Is this normal?

 

I change my synthetic every 3500 miles, or so. Rarely addd any, maybe 2-4 ozs. I live in WI so my engine may not run that hot.
