My husband has an 08 SE Dyna as well and is using more than 1/2 quart every 500 miles. I ride behind him and can smell oil, but don't see smoke. HD dealer has done 3 leak-down and compression tests and 3 500 mile oil usage tests and still has no clue. Any input about this would be helpful......

 

i have same problem plan on bringing in for valve seats etc
