Would you guys be interested in a bypass filter system that is even better than the one advertized it Diesel Power? That system has a 4 micron filter. Our system has a 1 micron filter(average oil filter is 10+ microns). I have the oil analysis to prove that infact the oil in our test vehicles is actually cleaner after 10,000 miles that it was the day it was put in. (Read: CLEANER THAN NEW OIL) Check out the US website and let me know if your interested. www.kleenoil.com click on kleenoil microfiltration. We have these oil systems on all of our big trucks(3 Kw's and 4 Macks) as well as all of our construction equipment(over 40 pieces of equipment) I wouldn't promote this product if I didn't believe in it as well as have it on over 10 million dollars worth of our own equipment.
