I know there are a lot of Prius drivers on the forum so I hope you can help me. I have a friend who has a 2007 Prius that seems to be burning a lot of oil. I don't think it is leaking because there are no spots where it is parked. It only has 180k miles on it and the engine sounds fine, but I found it 3 quarts low on oil when I first checked it out. I just added another 3 quarts after it was driven less than 2k miles (mostly highway). Any possibilities such as crankcase ventilation issues that would be simple and inexpensive to check/repair? Is it possible that I am doing something wrong when checking the oil?
Thanks,
