"If you are one of the many people who let a windshield reminder sticker govern when they get an oil change, here's our advice to you: Drop that habit. Instead, follow the automaker's recommended service intervals. In many modern cars, your best bet is to rely on the vehicle's oil life monitoring system to let you know when it's time for a change.
Let the Manual Guide You
Oil change information is in the maintenance chapter of your owner's manual. If for some reason you've misplaced your owner's manual, many automakers have put their manuals online. You can also search our Edmunds Maintenance Schedules. We have an extensive maintenance database on vehicles dating back to l980.
In many instances, you'll find that the owner's manual lists two service schedules. These are based on "normal" and "severe" or "special" driving conditions. Read the descriptions carefully to see which schedule reflects how you drive. In our experience, the vast majority of people fall into the normal schedule.
Trust Your Oil Life Monitor
In recent years, a number of automakers have installed oil life monitors of varying complexity in their vehicles. The more basic versions are more maintenance minders than actual systems. They're based on mileage, and switch on a maintenance light when the vehicle hits a predetermined mileage range.

Based on your driving conditions and habits, the frequency of your oil changes can vary." [Continue reading]
