$450 chinese turbo and 600 plus HP(food 4 thought)

i'm on the second e bay t3t4 on a 2.3 ford,runs 20 psi, and yes the bushings got clogged up with burnt oil so the unit failed.the new setup has a better drainback hose,runs 22lbs now no failure in 5 months so far....

I am curious what oil you run and how often you change it?
