Unless you do at least around 100 evenly spaced hours every year, I think dumping the oil every 25 hours or 6 months, which ever comes first on a calendar basis, is actually going to be better for the engine than getting a filter and going to 50 hour changes. Changing the oil gets ride of all the acids and moist sludge in the engine and the internal corrosion damage resultingn from these contaminates, is the main reason for engine problems in low utilization engines. If you want belt and suspenders then get a filter but keep the 25 hour oil change interval
