That's awesome. I try to drive mine until it hits 5%, which this last round was about 8800 miles since the last oil change. It's still better than that 3000 mile BS that still gets spouted around.

I remember being infuriated hearing some guy on the radio give tips on how to save fuel for the good of the environment. He recommended 3000 mile oil change intervals to help fuel economy, never minding the vast amounts of motor oil being wasted. I mean, even recycling takes energy.
