Here's a fun topic for discussion:
How does viscosity affect the leakdown rate of hydraulic lifters? leakdown rate can have an impact on valve events, and my intuition tells me that higher viscosity oils will bleed down slower.
How does this affect performance? Is it possible that one could GAIN 1-2 HP by running heavier viscosity?
Anyone know anything about this??? ![[Confused]](images/icons/confused.gif)
