I have to try it... And since I have an extra IP now, I figured it will be a good experiment. I keep looking at the now 500 gallons of used trans and oil sitting in barrels for free... It worth it to buy one of the 1500
http://www.simplecentrifuge.com/ machines. Heck thats 2k in fuel sitting there so the machine pays for itself from the first haul. plus I have access to another 1-2 hundred gallons a month..
OR by some simple math
Centrifuge = 1500
500g Oil/trans fluid free = -2000
I just made 500 bucks. Then profit 400 to 800 a month from the new free oil trans fluid. Within 4 months I've actually made more than the cost of any car I have to pour it in...
