I need some help with what oil to use that is cheap that I can use as storage oil. My bike has 6000kms on the current il and I would like to change it before I store it for the winter so that the crappy oil doesn't ruin any seals sitting for 6 months. Who has experience with using a cheap grade oil such as car motor oil you can get from crappy tire? I know it can't have anti friction additives in it because it will ruin the wet clutch right? Can someone suggest a brand and viscosity for a motorcycle? Thanks a bunch!
