How often should I get an oil change?

Most oil change places suggest every 3 months, or 3,000 miles. I've got a second car that isn't driven too much and usually doesn't reach 3k miles until about 6 months or so. Should I still be getting an oil change every 3 months?How often should I get an oil change?
I grew up with the understanding that you should change your oil every 3 months or 3,000 miles. I think that still should be followed with older vehicles.



These days, however, with the more modern vehicles and better oil formulas, it is more like every 5,000 to 7,500 miles. Most vehicle computers are programmed to let you know when it is time (a "Service Engine Soon" or "Change Oil Soon" light will appear), depending on driving habits and conditions. Check your owners manual to see when yours is recommended.
Read your owner's manual. It will say what to do. Likely it will say the normal intervals are 5000/6months.



However, if you're not reaching mileage, You can probably safely go 1year between oil changes.



The 3months/3k miles is bad information for modern cars and you are wasting money (as well as natural resources) by over maintaining your car.How often should I get an oil change?
The 3,000 mile myth was started by big oil the late 1970s. It was started for no other reason than to make money. If you have the kind of money Exxon and Texaco have, you can buy enough advertising to convince people of anything.



Most automobile owners manuals say to change the oil every 7,500 miles under normal driving. Just check your manual and spread the word.
On my wife's Lexus it's changed when the on-board computer says it's time. Typically about every 7500 miles. On my Jeep that used bouncing around the desert back roads it's changed every 3000 miles along with the air filter.How often should I get an oil change?
