The viscosity will also affect how quickly the hydraulic lifters can bleed off pressure. Some vehicles will experience 'pumped-up' lifters if the viscosity is too heavy and RPM's are high. This, of course, can lead to poor performance and burned valves and, in extreme cases, possible interference with piston travel.
So higher viscosity will create poor performance and cause the car to burn valves???
