So one of these noobsicles on facebook posted a link showing that California has a website up claiming that the 3,000 mile standard of changing your oil in your car is not correctly. So I decided to take a look. The website is here: http://www.checkyournumber.org/ My car, when run through that website, claims the oil should be changed every 10,000 miles. Now, I thought, I wonder if this is true and that is what is said in the manuals that no one bothers reading. So I grabbed my manual, checked the oil change section, and the manual claimed that depending on the driving circumstances, you need to change your oil between 3,000 to 10,000 miles (3,000 mandatory if you drive in a dusty locale). So, since I saw that section on the forums about Mechanics, I figured we must have a lot of mechanics on the board . I'm wondering if my car really can be driven a few more 1000s of miles before an oil change or if this site is going to get a lot of people to damage their engines.
