Automatic Transmission Service and Repair

If you ask five people, you’ll probably get five different answers. Ultimately, it depends on the car, the driving you do, and the type of oil you use. Conventional oils have a much shorter life than synthetics and should be changed every 3000 miles or every six months. Modern cars running synthetic oils have much longer intervals, with some manufacturers stating cars can go 12000 miles between oil services. The more frequently you change your oil, the better. You can’t overdo it. A good interval on modern cars is every 5000-7500 miles. High mileage vehicles (over 100,000) should be serviced at least every 5000 to ensure proper lubrication. If you have an older vehicle running conventional or synthetic blend oil, consider changing the oil every 3000 miles at least. .
