Your foot is nailed to the floor, so to speak, at least until the warranty is done. Regardless, here are the results of some research I did on the subject. The objective was what ??w40 oil had the best ZDDP values. Most motor oils today are 800ppm and less. The manufacturers argue that the oils are so much better today you don't need as much ZDDP. Okay said I and promptly starting looking.
Red line synthetic motorcycle oil (my choice) 10w40 zinc=2125ppm,phophorus=2100ppm,molybenum=425ppm.
Mobile One Racing 4T 10w40 (ZDDP=1700)
Royal Purple XPR 10w40 (ZDDP=1500-1600ppm)
Mobile 1 Turbo Diesel Truck 5w40 (ZDDP=1300)
Mobile 1 Formula M 5W40 (ZDDP=1100)
