I use two different wvo systems on my vehicles (vegistroke and greasecar). Would using magnasol help dewater and "clean up" my wvo? Or is this something that only applies to biodiesel? We use the fryer polish at church to clean the oil after every fish fry. I get the oil when the fish fries are through. The oil from church is WAY cleaner than the two restaurants that supply me oil. Maybe we just fry better.
The greasecar is manual (I think they may have the automatic option available) and the vegistroke is automatic. I like them probably like them about equal. Each is good for the vehicle they are in. The vegistroke was easier to install, but it was also quite a bit more expensive. Go to each of their websites for lots of info. Both have forums.
