Why does my KTM 250 XC-F 2018 have high oil consumption?
- K
  Kimberly BarnesAug 28, 2025
  High oil consumption in your KTM Motorcycle can be attributed to: * A bent engine vent hose; ensure the vent hose is routed without bends, and replace it if necessary. * An engine oil level that is too high; check the engine oil level. * Engine oil that is too thin (low viscosity); change the engine oil and oil filter, and clean the oil screen. * A worn piston or cylinder; measure the piston/cylinder mounting clearance.
