The 1KFR comes with sensitive build specially the Oil Rings on piston, the event incur right after 60k KM on ODO, the oil rings gets hard and start to deplete oil, I have the practical experience with multiple cars in my circle, this will goes on, since the oil ring is hard, so replacing them is more like replacing piston n opening of engine, I recommend keep using it with 5W40 in winters/summers or 10W40 in Summers, damage is done, so drive it long as possible it will go on more than 150k KM, mostly drive it more in eco mode.
Change oil every 3000KM, you will lose Total between 500ml to 1000ml, ignore and keep driving just top up 200-300ml every 500km,
