This question already has an answer here:
My dealership overfilled my engine oil in my 2014 Forester in Jan 2019, by 2 litres. I complained of problems with the car chugging, sometimes severely, several times. I drove the car for 6-7 months like that, driving approximately 1,300 kms with the overfilled engine oil. The engine is a CVT. One time the car chugged consecutively, really, really hard, throwing me forward each time, almost stalling. I wonder if damage was caused at that time. There is approximately 33,500kms on the car right now. Problem has been corrected for about 2 months. Would any amount of damage be caused by this over filling?
