I am reposting my recent UOA because the board seemed to eat my first one...
On a Kubota 1.6L diesel tractor, 107 hrs on Amsoil 10w40 & 424 total hrs on engine. There were 2 qts of make-up oil added (357h & 392h) due to bypass filter changes. I plan to lengthen the bypass element change to 50 hrs and retest the oil at 200hrs. Any comments?
