Hello everyone, I have Toyota yaris cvt 1.3 and I've driven it 50k. I recently got my gear oil changed. I'm a bit confused bcoz the recommended capacity is 4L but my car just took 2.5 litres. Coz the mechanic did not open it's chamber as he said that it's a new car no need to open the chamber and at second service the chamber needs to be opened and cleaned and then it will take 4litrs. So please let me know is it okay to drive now?
