Is my oil ready?

Postby Veggie Mike » Thu May 19, 2011 3:03 pm

I centrifuged and heated my wvo using a Sunwizard inspired filtration rig, but the oil remains dark brown.... I put a same in the fridge and it didn't separate into any layers... Any ideas?

My oil is from a chinese food restaurant who uses Messina Vegetable Oil - it doesn't say anything about Partially Hydrogenated on the box...
Thanks in advance

Did you test for water in the oil to evaluate how well your CF set up is working for you?

Does it smell rancid or pain thinner-ish orrr?

How much gunk was in the rotor after CF?

Have you CFed again to see if more came out as a test?

If no water and no rancid smell.... sounds good to me?

Hot pan test showed no bubbles at all.

The oil smells normal for a Chinese restaurant and it was taking from a pot they cool it in after being changed out of the fryer. It never went to the dumpster.

First cycle through the cf yielded a moderate amount of particulate in the cup and the subsequent 2 tests yield less and barely anything at all.

I'm just a little gun shy, this is my first batch of oil I've tried filtering. I've seen oil the shade of iced tea on these sites and my oil is very dark still.

Sounds good. The color doesn't tell you much. You can still run it through a 1 or 5 micron filter while pumping it into your vehicle so you feel even safer.
