    Hi Members,

    I have 2018 Prius Prime plus, I have driven 13000 miles, 80% of those on electric, my questions are:

    1) Is 80% EV driving bad for my battery and will it violate battery warranty in any way?
    2) Can I do oil change only once a year(or less frequent that 1year) since car is driven mostly electric?

    I drive optimally so my practical range is around 36mile on a full charge and so far it is keeping up, fingrse crossed

    1. No. The Prime is meant to be driven in EV mode and charged each day.

    2. Isn’t that the scheduled maintenance? I thought the oil change interval is once a year or 10,000 miles whichever comes first.

    welcome!
    i've debated going more than a year in the pip, but i'm too chicken to try

    all batteries degrade with use and time to some extent, but prime is definitely designed to be driven ev, so i wouldn't worry in the short term.
    long term, everyone is going to be in the same battery boat at one point or another, there's no knowing when though.

    i have 43,000 miles on my 7 year old battery, and it still gives me 14 miles range in mild conditions

    Yes that is scheduled maintenance, I would hate for mechanic to touch my car unless necessary, scheduled maintenance is based on some % driven on gas engine, I am not sure what assumption, Since I drive 80% electric, should I wait longer for oil change may be 20K miles?

    If you want to keep your warranty, I would suggest following the scheduled maintenance until you’re out of warranty.

    Follow this advise.

    Once you are off warranty, you can do it your way, which certainly could extent out past 1 year or 10K miles...

    yes, li-on. i'm at a total of 43k ev and 21k hv, around 67%. but the ev is climbing since i retired. i drive around 90% ev without my former commute.
    i was getting about 16 miles the first summer. it declined in years 2 and 3, the leveled off.

    As others have already chimed in.
    1. No. There are plenty of Prime owners who are doing near 100% EV driving.
    2. Oil change is every 10K miles or 12 months whichever comes fist. If you drive less than 10K miles/year, once a year oil change is perfect. If you drive more, then stick with every 10K miles.

    You could do DIY oil change and other minor maintenance to avoid having a mechanic touch your car, but you will be forfeiting the free Toyota Care for the first 5 visits to the dealer. It's totally up to you.

    As has been said, it's meant to be driven in EV mode. That's considered normal wear for the Prime. Except for vacation trips, I drive 90-95% EV.

    As to the oil, do what the manual says if you want to keep your warranty. Keep the receipts if you change your own oil.
