With Mobil 1 I changed my oil once per year. (6 race weekends and 3000 miles total). Now I use Valvoline and change it every 6 months. Had my engine apart 2 years ago for a cracked Mag case and it showed very little wear. I put it back together with the old rings and valve guides. Still running strong.
