Hello, I have a 2010 Prius with a little over 120k miles and I'm curious what actual services should I be doing or having the dealer do vs what will the dealer be trying to upsell me. From the Maintenance Log I see Inspect and adjust all fluid levels Replace Cabin air Filter (Watched a Youtube video and will just order a filter and do this myself) Replace Engine air Filter (already done myself) Replace engine oil and oil filter Replace spark plugs Should I be looking at replacing the Transaxle/Transmission fluid? Engine coolant and inverter coolant? Or just topping off the fluids? Debating replacing the spark plugs myself. Would genuine Toyota Spark Plugs be fine (from ebay) or should I get another brand. Many thanks!
