Why does my Husqvarna FC 450 2019 have high oil consumption?

Several factors could be responsible. A bent engine vent hose can cause high oil consumption, so ensure the vent hose is routed without bends or replace it if necessary. Also, check the engine oil level; if it's too high, adjust it accordingly. Using engine oil that is too thin (low viscosity) can also lead to high consumption, so change the engine oil and oil filter, and clean the oil screens. Lastly, worn piston or cylinder can be the cause, so measure the piston/cylinder mounting clearance.
