Diesel RVs: [diesel_mercedes] Re: Re : Veggie Oil KILLS Diesel Engines

Lawrence,

I think you are both right and wrong about Mike. You may have discovered something new - when filtering thru denim, heating the oil may make the filter less effective.

But it may or may not apply to centrifuges. I feel that heat would make Mike's centrifuge more effective, not less. But since you tested and found silt, I think Mike may want to test his also. Nothing elaborate - just the largest transparent container he can find. Fill with some of the output of a centrifuge run and let stand for two weeks.

Since his rig makes it easy - he might clean the centrifuge, wait for the oil to cool to room temp, and then run the oil again while cool. If there is anything in the bowl after the second run, maybe he needs two runs.

I've had many a settled highly heated and refined five gallon jug of oil have silt on the bottom. Heating while filtering allows more through the filter media. I cold filter through denim. I get very little silting after letting filtered oil sit. If I worry about water I just don't use it. Settling gets rid of most of the water. My oil looks crystal clear. If it's foggy I just don't use it or much of it. Lawrence Rhodes........
