Do you guys have the same problem for engine oil consumption?
Here is my statement to UMW Toyota:

My dad bought me a Rav 4 model year 2006, is having serious engine oil consumption. Dip stick was half at line measurement and refilling it every 2 weeks for 1 litres plus to Full line JUST IN CASE anything happen such as drain out without any light signalling or engine burn. Its been like this after 75,000+km mileage since August 2014. I have researched online that Rav 4 model is in the list of suffering oil consumption + knocking/rattling sound. It is cost consumption too by adding 2 bottles(1 litre) of engine oil every month. Please tell me what i should do besides sending the car to UMW for Oil Consumption Testing since this issue has been years happened since 2012.
