I live in northern VA and work in the District of Columbia, so it's a lot of city traffic for my CX-5. The owner's manual, and my dealer, said to change it every 4 months or 4k for city driving. They both said 6mos/5k for country driving. I enjoyed reading this thread, thanks for all the info everyone.
Just do it every 5k miles to keep your life simple. Don't think its too little as these cars can do 7500 miles no issue between changes even 10k.
My maintenance for new cars is every 5k oil change, 10k tire rotation, 20k replace air filter.
