I'm skeptical that Mobil 1 needs to be changed in these cars every 5000 miles or 12 months. I mean, really?

I'm especially interested in hearing about the duration of time between changes...mine sits for 6 months and then hardly gets driven 2000 miles per year.

I know what's recommended, blah blah blah, but is there science involved, or just Porsche enthusiasts OCD?

Thanks
