I'm switching oil brands from OEM Suzuki to Rotella, and my Suzuki Oil filter only has 3k miles on it. I'd like to know if it is advisable to change filters if you switch oil brands. Thanks for your help.
i hate how the owners manual says change oil at x amount of miles and filter at xx amount of miles. when you dont change your filter you leave old oil in your system, which quasi defeats the purpose of changing your oil. i change oil and filter every 1500
