how many oilguard users do we have here? are you happy with your system? i just bought a brand new oilguard system off of ebay for $15. 50!! it is for a 7. 3 powerstroke but that doesn't matter since i will be getting my own lines anyway. which brings me to my next question... where do i get stainless braded oil line from? i figure that would be about the best line material to use. by the way... did you all see that rotella improved their oil a bit? they added to their api rating.
