I did state in my OP that 3K is ridiculous. The reason I created the thread was to get other forum members opinion on going to 7800 miles from 5000 miles on oil changes and more frequent filter changes. After reading the article I posted, I might be wasting money for no reason. My neighbor changes oil every 2000 miles on his 2009 Pontiac G8, and he's 100% convinced that that's the proper thing to. I've told him that's WAY TOO frequent, but oh well. I used to change oil every 3000 miles, but knew that interval was too frequent. If changing your oil every 3000 miles does it for you, cool.
