The 5 cSt viscosity of Mobil jet oil (as are most jet oils) is very stable.That Lada which is running during -40°C winters and most certainly hardly ever reaches +100°C operating temps. Actual viscosity with this jet oil? Probably from two digit to four digit centistokes all the time. That's why I guess.
.
Lada or not, the point being is that Mobil jet oil (or any other jet oil) does not have the necessary additive composition for terrestrial IC engines.
