    The salesman that showed me the Prime I bought said that it keeps track of the milage for the gas engine separately from the electric motors.

    If that is the case... do you end up doing oil changes based on the actual gas engine milage, as opposed to the road milage?

    In other words... my daily commute is 34 miles. If I really get 25 miles of that as an EV, shouldn't I need less frequent oil changes?

    no one knows. we pippers had this same problem. the manual still says every 10k or one year, so i change it every spring, since i only drive 6-8,000 miles per year, and only 35% of that has been gas.

    I would just follow the book, on oil changes, 10K miles or yearly.

    Actually I didn't know the frequency was so low... My 2007 needed an oil change every 5000.

    it changed in gen 3, with synthetic oil.
    there may be other concerns in cars that hardly ever use the engine, but we don't have any data that i know of.

    In Canada it changed (similarly) with Gen 4.

    I would agree that it would need changed less frequently than a normal gen4. Someone may hardly ever use the gas engine and thus the oil would be just as good as new 6 months later as it was the day it was installed. One thought, Does the prime engine start when a full power load is applied to the gas pedal?

    For two years the dealer will change your oil, don't worry, every 10,000 miles, at your 5000 mile checks they rotate wheels and top off fluids and enhance your experience

    Are you saying that oil changes and tire rotations are free for 2 years? If true this is the first I've heard of it.. my dealer is trying to get me to buy a maintenance contract to cover oil changes and rotations.

    as far as i know, all toyota's all across the country. i got it way back in 2012, and still hear the ads.
    only caveat might be southeast toyota, they don't have to play by the rules. idk if they offer or not.

    They gave me the vin for the car on paperwork... I looked it up to see if it is eligible for Toyota care... Toyota's site says no... but that may be because it's not actually sold yet. I also looked it up on free vin check website out of curiosity and that has no records on it.
