Why does my GAS GAS Motorcycle have high oil consumption?
- S
  Sarah WrightAug 15, 2025
  High oil consumption in your GAS GAS Motorcycle can stem from several causes: * A bent engine vent hose: Ensure the vent hose is properly routed without any bends, and replace it if necessary. * An engine oil level that's too high: Make sure to check the engine oil level. * Engine oil that is too thin (low viscosity): You should change the engine oil and oil filter, and clean the oil screen. * Worn piston or cylinder: In this case, measure the piston/cylinder mounting clearance.
