I'm 72 years old. Last year I bought a 2012 Equinox 2.4 FWD with 99,000 miles. Great condition and runs perfect. Recently had to replace the intake/exhaust solenoids because of a code. Living with my girlfriend who also has a car and we switch car use. All of my driving is local. Car is used only 2 or 3 times a week. At the most, I put 20-25 miles per week on the nox. Very seldom do I do longer trips. Upcoming Ohio to NY trip planned in September. With the low mileage that I put on the car, how often should I change oil and filter?? I just had it changed after I replaced the solenoids.
