I helped instal a frybrid kit in a buddy's car. and he's been pleased as punch with it.

he has an 82 240D with 119K. body's beat though.

he's run nasty looking hydrogenated oil thru this thing in the dead of winter in northern Wisconsin, never missed a beat. 1o K miles so far? the only thing he needed to change is run it thru a couple of polishing filters before putting it in the tank.

I've been amazed.
