Your owner's manual always has the final say for your specific car.
Follow your owner's manual. As a rule, conventional oil about every 5,000 miles and full synthetic every 7,500-10,000 miles, and at least once a year even if you drive little.
Once a month and before long trips, with the tires cold. Correct pressure improves fuel economy, tire life and safety. The right number is on the sticker inside the driver door, not on the tire sidewall.
Most last 3-5 years. Have it tested every autumn once it is over three years old, because cold weather is when weak batteries fail.
Oil changes, tire pressure and rotation, brake inspection, and keeping coolant and other fluids at the right level. These prevent most expensive repairs.
