I have a 2007 RAV4 with about 121,000 miles on it that appears to burn oil.

What is your question?

Is it common for older cars to be having problems with high oil consumption? I've been told "it's common for older cars to burn oil and nothing can be done about it." Is this true? If not, what can be done to fix it? Why do older cars burn oil faster? I don't see any leaks. Thanks Christine
