    Yes, my 2020 L Eco is a fantastic machine! Bought it new slightly more than 4 yrs ago....average 97k miles per year. Over 80 mpg during that time. Original brake pads. Big battery still working perfectly. I just replace tires every 100k with OEM's....

    Also I replace my own spark plugs every 170k miles. Have drained & refilled coolant/inverter fluid 3 times. Use Mobil ONE 0w/16 every 10k of highway driving. Always run 50 PSI in OEM Bridgestone tires. Always use same technician @ the Toyota dealer....slip him $25 cash every time. Complete oil change with tire rotation only cost me $38, I bring my own oil & filter.....

    I am a daily driver on Seattle area freeways....I deliver new cell phones, am driving about 1800 miles per week. Am a long time experienced hyper-miler in the shared techniques of my friend Wayne Gerdes.

    How much oil are you burning? My old PriusC started burning slightly less than a quart every 10K mile oil change on 0w20 when I hit around 100K miles.

    Congrats, but I'm finding the 80 mpg a little hard to believe, since you are in hilly Seattle and I'm only getting about 55 (per fuelly) driving very cautiously, mostly in flat-as-a-pancake Florida. Do you use fuelly?

    Apparently not, since I only see 72 mpg as the maximum recorded by a single user owning a 2020 Prius. I don't feel quite so bad, fuelly shows the average mpg for a 2020 Prius as about 50 mpg.

    Hi Davecook.....I am a decades long hypermiler. I averaged much higher in my Gen 1 Honda Insights. 80 mpg in this Prius is not very hard to do, using all the highway and city techniques. I don't do widespread any longer, so my MPG has decreased from 84 to 80....

    Actually your oil change cost you $63 plus the cost of the oil and filter when you factor in the tip you give the same guy each time.

    Not so much as oil burning but losing oil do to the pcv and the oil sitting in the intake manifold.

    Thats when you would install an oil catch can to prevent all that and fouling your catalytic converter.

    Hi davecook89t
    Never heard of "fuelly", but I log my fuel stops and also calculate my exact mpg with odometer mileage and my GPS. Rather than 80.8 indicated, my true mpg is 79.45 over 400k miles...

    Wayne Gerdes does slightly better than me.....he is the best mpg driver AFAIK. We both use techniques such as momentum driving, coasting, driving a bit slower than most cars, tire over-inflation, staying off the brake pedal, looking WAY ahead to the next traffic light, lane positioning to the crown not the groove, concrete over asphalt when possible, keep the car light and also aero clean, stay with OEM tires, etc etc....

    Yeah the odometer is the way to go. It's much more dependable and foolproof than trip meters. I do reset the trip meter at each gas-up though, for feedback, backup, and for a laugh: the mpg it displays is invariably "better".

    I'm guessing you've seen this:

    He's even in the Seattle area.
