thankfully i don´t have f1 engine, where must circulate hot fluids for several minutes (before start), because of too tight tolerances...
sane person would not jump too high with viscosity... like from 0w30 to 20w60,,,
people should watch engine production lines, inspection runs them at full blast, either it will survive or will be scrapped. no run-in.
