Hello. I just purchased a 19 Corvette Z51,LT2, Long Beach Blue. My questions is as follows. One sales guy said first oil change 5000 +/- 1-2k miles depending on how hard driven. A second sales guy recommended first oil change at 500 miles regardless of what service manual recommends. I will be a weekend driver only, purchased car just to cruise. I don’t buy the 500 mile first oil change. Any thoughts.
