I am ready to order my centerfuge, I am looking at ordering the dieselcraft OC20 I believe. The same one from Sun's original system. My brother in law is the manager of a BBQ Ribb joint and his best friend is the manager of a sports bar. I know I can get oil from both of them but it is probubly not very clean oil. The ribb joint puts the fat from the smoker in there oil so it would be the worst. The sports bar serves allot of burgers so there would be some fat it theirs to. If my filtering system is the same as suns with the pump at the lowers point and the heaters in the pipe will using this oil be a problem? Will the centerfuge remove the fats? If not will they cause problems or will the engine just burn them? I am planning on aproaching some other resteraunt that have better oil but I will alway have these two for backup and I would rather have something like this as I get going so I don't hassle a better supplier with all my mistakes as I learn. Any opions are welcome.

As long as your fuel system heats the oil/grease so that it is 160+ at injection, your engine will burn it. In addition to that, if you have a very high gel point, you are going to have to to ensure that the fuel system is completely heated or purged so that it doesn't plug up.

As far as filtering, you are going to have two issues to deal with. The solid food waste and the solid grease. If you heat then filter you will be able to extract the solid food waste and solid grease will pass through. However, you will get sediment in your clean oil.

You are going to have to determine what your conversion can tolerate and what your yield rate is going to be. If it is practical to settle and only draw from above the separation, you may be able to get high quality oil. You are going to have to see what you have to work with.

Running that little OC20 cold would plug it up quite quickly with solid grease.
