Heres a pic. of Great & Junk collected WVO.

The emty cubbie on the right is pristien WVO Canola (cola in color). Notice there is NO SCUM film on the cubbie (cubbie sides drain to clear in mins).. The oil came from a food manufacture plant. No fat/lard/wax/grease. The oil is used in a 1000 gal. fryer with a great filter. I still filter the oil but find VERY VERY little debri in my 5 micron filter.

The cubbie on the left is junk WVO. One third is fat/lard/wax/grease..
Notice the SCUM(yellow line) on the top of the junk WVO cubbie. The cubbie has been in my garage for 3 weeks. The scum film line is still there after 3 WEEKS in a 70 to 80 deg. garage!!!

I feel almost all WVO problems are do to JUNK WVO leaving a scum film on filters & tanks..thus clogging the fuel system in one way or another.

Theres no way that junk WVO with SCUM is going in my car. Its not worth it!
I guess what im saying is even after the top part of the junk WVO has been filtered... its still SCUM WVO. Just my 2 cents.
