THAT is the question nobody seems to agree on. Different makes have diffent change intervals. One recommends 3 months or 3000 miles, while the other recommends twice a year or 8000 miles. Most garages seem to say 3 to 4 months or 3000 miles, though consumers reports did a test a few years ago on taxis in New York City and came out with a recommendation of 6 months or 6000 miles. The choice is yours, but I would err one the side of caution. Every 4 months sounds like a good compromise.
Its recommended every 2500-3000 miles. Never 5000.
After every 3000 miles
You should consult your owners manual to see the recommended length of time. Often, it is not the 3,000 miles recommended by the local oil change place and can be up to 10,000 miles.
Recommended at every 25,000 miles
Every 3000 miles recommended.
My husband worked for an air conditioning company and they recommended that you change your air filter once a month.
The manufacturer recommends you change the motor oil every 7500 miles, or every three months. As the vehicle gets older. It is recommended to change the oil more often.

It has a chain. No recommended replacement interval.
Use long life oil and change it every 10k as opposed to recommended 20k intervals.
Every 3 months or 3,000 miles (whichever comes first) is recommended for most cars.
