If I was going to lay it up entirely for the winter, yes, I know I should put in fresh oil and not start it during the layup period.
But, suppose the weather is such that only Jan & Feb have zero riding?
I had new oil about 2500 km ago.
What is the real damage done by used oil? Do the new nikasil coatings make it more or less important to change before storage?
Cars often get stored for months without oil changes, why are we so anal about our bikes? Are there good reasons?
