I have a 2017 Prius 3 or 4 with 90,000 miles. For the last year, I've been getting 36-42 mpg. More than once, the dealer gives me a long list of things to be done as scheduled maintenance for about $3000. I'm always skeptical so I take the list to my regular mechanic. He says, don't bother with any of those except flushing transmission and brakes. Hmmmm? I just drove my friend's Prius 3 or 4 - 2019 with 60,000 mi. Feels more peppy and he consistently gets 48-55 mpg. Any ideas? Injectors? Tune up? Thank u
