Hello everyone.
A couple of days ago i got grande 2018 cvt oil changed from Toyota GT. They included a 4 liter red cvt fe tin in the bill. However, when i was leaving the workshop they handed over me the remaining oil. By sloshing and weight it seemed that there is around 1.-1.5 liters of unused oil in it which means they only poured 2.5 - 3 liters of oil.
Is this fine? Or is there something out of recommended practice here? I am a bit terrified of the horror stories of cvt specially after first cvt oil replacement. Mileage is 57k.
