This extended warranty thing has bugged me from the beginning, and this is just another example. 10K miles/one year oil change is fine, even recommended, for the factory 2 year warranty. Why isn't it good enough for the extended warranty, which calls for 6K miles/6 month changes? No rational reason I can think of, except a possible loophole to avoid warranty payments for those owners who stick to the factory recommended interval. Just don't get it.
