I've used it for years, so has my Dad. I plan to continue using it.

But STP is not meant to be used as an assembly lube. You should just use actual assembly lube.
 
If an engine is going to be put into use in the near future, ie. not stored, STP works fine as an assembly lube.
But I will no longer use it on Cam lobes or Lifters.
 
Old mower and pump motors..... will help with blow by. I suppose a 50 wt instead of 30 wt would do that.
