I'm sure the fuel in the oil was due to on starting the the Z in the morning had on one or two cylinders not firing for about 2 min )No idea, has not happen since. The other is silicone, which may be due to the Z1 silicone oil cooler hoses, otherwise M1 0W40 is doing a good job. Oil had 3500 mile at oil change -fill was 4-7/8 Qt with oil cooler drain.
