And I thought I over analyze! Geeze, leave the oil in there and just keep up with the Bi-annual brake fluid changes. THAT matters, you don't want to have to be replacing brake components that fail due to water corrosion pitting the surfaces. Basically oil and coolant are lifetime, no scheduled changes in booklet:
- each 2 years, pollen filter, brake fluid
- each 4 years, tire filler bottle
