First oil change or every oil change? First at 2,000 sounds about right... every oil change at 2,000 sounds like a bit much... but if there is a warranty involved, I would do the every 2,000 as the mfg. recommends.My 810hp Shelby recommends oil change at 2,000 miles. Is this assuming it’s driven hard ? I’ve only been past 6,000rpm a couple times. Mostly city and interstate.
