Oil and spark plugs, totally the same thing.
Oil and spark plugs, totally the same thing.
They both wear out with use, they both degrade over time. These have been your arguments.
Suggest you change your oil before storage. Used oil is full of acids that during a long rest - 3 months of winter, simply EAT away at your metals.
No need to change oil after the winter. It's as clean as it was in the fall.
If you store a bike at a dealer... make sure the oil is changed immediately. If in his garage/basement it sits until the end of february before he changes your oil, the acids have already done their damage.
FWIW
