If you like to keep a car long term, I'd recommend changing oil every 5-6k miles. |

I sent oil off to blackstone that had 5K on it. They suggested/ok'd going longer ~7K
My current "test" interval is Filter only change at 5K miles then full oil & filter change at 10K I plan to test the oil again to see what it looks like. If it's bad, I'll moved to a 7.5K Oil/Filter interval and call it done. |
