I have been using the 15/50 in my ZL1 1LE for 26 track days in 2023. Used GOODYEAR 3R for 20 days and CONTINENTAL for 6 cool and wet days. No issues except for my frozen lifter. Not oil related? Changed the oil twice. The dealer says to use 0/40 and that there is a bulletin rescinding the 15/50 spec. Bought two sets of tires this year. One replacement 3R and one set Continental which are now trash. Also replaced rotors and pads.
