So the Car is in good condition everything is working fine and perfectly. It has 100,000 miles on it. While I was buying the car the owner told me that to never Change the Gear Oil or else there will be many problems. He also said to just keep changing the Engine oil every 2,000-3,000 miles and the car will be fine. What should I do about it? I would think not changing gear oil will have a problem in the future but the owner said to never change it or else the car will have many problems.. so should I just not change it or what? any information is appreciated.tweakbox appvalley https://vlc.onl/
