Making Big Power its rule of thumb to change the oil every 15-20 passes in the 1/4

I dident last year because i dident know any better but i will this year…

Maybe I’m not making “big power” but I did 5000 mile oil changes last year running 11’s at 130 stock motor and so far this year I’m up to 1000 miles (25+ passes on saturday alone and many tuning pulls). Oil can surely last more than 20 passes.
