My 2018 Outback is closing in on 59K miles. The local Subaru dealer's recommended 60K mile service schedule includes: oil & filter, tire rotation, brake fluid, transmission fluid, engine coolant, spark plugs**, inspect brakes, inspect HVAC operation, lubricate locks and hinges, road test drivability inspection, and a multi-point inspection for ~$1300. The schedule does not say what will be done about the spark plugs. What do you recommend I ask the service manager? Which of these services really should be done by Subaru. I have had the oil & filter and tire rotation done elsewhere. Thank you for your advice.
