What is the best Bobcat Tractor Engine Oil Change Interval? 50, 200, 350? Let's Compare.

An owner with two Bobcat CT5555 tractors ran engine oil analyses at three different change intervals, 50, 200, and 350 hours, and walks through the actual Blackstone lab numbers side by side, focusing on copper, lead, and tin wear metals. The data challenges Bobcat's 400-hour spec. More of an open question than a conclusion, but the real test numbers make it useful for CT5555 owners weighing their own maintenance intervals.
