The $1000 I spend on a Centrifuge seemed like a lot of money at the time. But local greasers would come buy when they had problems with there cars and it usually was they needed better filtered oil. Now I have a few word of mouth customers that purchase clean WVO from me. It covers the cost of the electricity and the purchasing of the equipment.

I use two 30 gallon water heaters. I have changed out about 20 water heaters in the last ten years to tankless and I keep the old ones a few times. The 30 gallon tanks are on the top shelf of a restaurant storage shelf---Free from where I get most of my oil. I have a transfer pump---Free from the dumpster area near that restaurant that was being discarded because it did not work. (it had a piece of debris in the gears.) The middle shelf holds the Centrifuge and I have two 30 gallon buckets below the centrifuge.

Water heater #1 heats the oil until hot about 4 hours then it gets passed to the CF and into the white bucket#1 under it. Then it gets pumped into water heater #2. It goes thought the centrifuge again for about 4 hours to empty into the same white bucket below bucket #1. Then the timer turns on the pump and pumps it back into water heater #2. It does this three times until I turn a ball valve and it runs into bucket #2 and that is the ready to go stuff that gets transferred to the ready to go 200 gallon container off the back of my carport. I find this is the best way to get the oil really clean. Probably less than 1 micron. and water free. Electricity works out to about 4 cents per gallon.

I have two greasecars one the 2005 Mercedes and the second a 2006 Jeep Liberty. I change the motor oil and veg filters on both every 5000 miles. Works out great and never clog a filter, ever.
