I run 100% WVO year round, including in below freezing temps. WVO should ONLY be used in a proper heated two tank system. Regardless of weather/time of year. Or, make bio with it, but definitely do not run WVO in your stock tank in any truck. You're asking for problems.

The dirt comment made me laugh... most ridiculous thing I think I've heard yet about WVO.:pca1:

Let me put it to you this way and see if it make any sense to you....................

Ok - so you and the family go out to Joe's Diner tomorrow night and you each have a big ole burger and a huge order of fries - COOKED in vegetable oil - right?

And you don't think that oil is full of crap. Literally, parts and pieces off the fries dropped into the oil and now YOU'RE gonna have to filter it back iut, in order to run it in your truck?

Go for it pal, cause I'll take my used motor oil and hydraulic fluid any day!!!! I run it through a couple 2 micron filters and pump it in to my tank and drive down the road! I MIGHT change a filter once in 500 to 600 gallons just cause I fell sorry for it!!!!!

Do you think about what you're saying?

So there's nothing in used motor oil? I know when I send in for oil analysis my oil has always showed something, including but not limited to WEAR METAL PARTICLES. I'm sure those are good for injectors right?

No matter what you're using, it needs to be filtered, I don't think that's the question.

YOU said it was full of dirt? I would be more apt to think used motor oil has more dirt in it than any used WVO will. I run filtered WVO year round in my heated two tank system. I would however NEVER run used motor oil, though I know some guys do quite succesfully. I would take CF'd WVO over any sort of filtered WMO, any day. I wouldn't even run my WVO with your filtering method.

:c:

what about boiled and recondensed/cracked WMO? that would make it cleaner then any pump diesel or WVO out there

I'm sure there are ways to get it clean, I just wont use WMO anyways, just my own personal standing. I know guys use it and some quite successful. Success has quite a few different meanings in the alt fuel world I've learned though. I'm just sticking with what I believe to be the best PROVEN system out there for running something other than diesel. I prefer to keep my alt fuel system separate from my main diesel fuel system that came on the truck, and my kit allows me to do that. I can get home on either one if I need to.

i know what you mean. for some its being able to run their truck cheaper, as long as the cleaning process and the repair bills end up cheaper then when running on diesel alone than that to them is successful. for others it needs to work just as well as straight diesel and last just as long, otherwise it is a failure, even if they saved a bundle in the process.

i think most of us are the former but strive for the latter

Look - let's settle this stupid argument once and for all. I want you dto do TWO things:

1. Take an old broomstick with you and go to a local restaurant. Put the stick down the middle of the opening of their junk cooking oil tank. SEE!!! it's sitting there with NO support - STRAIGHT UP!! Thre's so much crap in the "oik" that it's supporting the broomstick!!!! Junk you're gonna have to filter out of it!!!!

2. Now - drain the oil out of your truck after 6,000 of hard towing. Put a toothpick (MUCH lighter than and broomstick - right?) and stand it up in the oil, the n let go. what happened? IT FELL OVER AND LAID FLAT IN THE OIL!!! Why? BECASUE THERE'S NOTHING IN IT TO SUPPORT THE TOOTHPICK - THAT'S WHY!!!

And cut with the "Well there's "something in the oil because a test detected ware particles", because I've said over and over and over that I filter my oil down to TWO measly microns!!

Do you realize how tiny a micron is?
Do you know how many microns a stock fuel filter is? Try 10, 20 and sometimes 30!!!!

Pal, If you like the idea of using 4 or 5 different filters to use that filthy wvo crap, then all I can say is go for it!!! If you do I won't have to worry abut MY sources drying up!!!!

If you can't see the difference in filth between used motor oil or hydraulic fluid and that crap that comes out of a french fry cooker I'm done trying to explain it to you!!!

After all the crap the refinery had to do to turn crude oil into diesel fuel and motor oil, filtering out a few french fry and hamburger bits out seems minor.

That might be the usual numbers for an oil filter.
I think you mean the 3 to 5 microns of a fuel filter, right?

I've seen primary fuel filters rated up to 50 microns for semi trucks, but they're always followed by a secondary filter rated closer to 3.
