Oil should be changed regularly.
If you are a moderate driver, about 15kmi per year, you are over due on many things. You can do those yourself, or have a shop to do a 60kmi maintenance package (it's not just a "check"):
- Change spark plugs
- Change air filter
- Change brake fluid
- Change transmission fluid/ filter
- Inspect/change brake pads
- Better to change coolant
These are minimum you should do. For a 60kmi package, about $300-400
The most expensive thing on cars is no maintenance!!
