I was googling for some out of box ideas for oil consumption and came across Krankvents in various forums:
I use mobil 1 and I installed some Krankvents. Stopped my oil consumption almost totally. I was using about a half quart every thousand miles.
krankvents have show some great results on vehicles that were experiencing high oil consumption, thanks for reminding us about those cool devices. I would certainly try them if my car was consuming too much oil.
i'm totally unaware of those "cool devices" and trying to learn more about it.
Anyone with any experience with them?
