WVO

Any legit resources for researching the pros/cons of WVO both straight unprocessed and processed??

Somewhere other than the tree hugger websites?

I guess not.

You talking about just filtering it and running as an oil or making bio diesel?

My brother and I was gonna run it a while back but could not find any stable sources

What exactly are you wanting to know? I've been running svo for over 4 years. :snoop:

Good and bad of running straight wvo..conversions needed, lubricating issues, mileage concerns. Same for processed biodiesel from wvo.

Need to write a paper for school and I can only find tree hugger Info. LOL

Here is some info I found in a google search that is not on "Tree Hugger" forums

The pros and cons of homemade Biodiesel vs WVO. - Dodge Cummins Diesel Forum

This one is about other setups in another country but covers some why they run what they do through the engines.

Biodiesel vs WVO?

I can give you my experiences with it non of it being 100% scientific. I have 4 p7100 trucks that I use svo in. 1 truck has a greasecar kit installed the others have no kit. After sitting for a couple of months I heat it to 180 degrees to make sure it hasn't any water in it. I then centrifuge 50 gals. for 24 hrs. at 180 degrees. The separate veggie oil filter in the kit truck lasts for over 20K miles. Normally
I end up changing it because I feel I should not because it's becoming plugged. The other 3 trucks I mix the svo with the diesel in the factory fuel tank. The ratio depends on the weather. 3 to 1 diesel in the coldest time of our Wisconsin winter to 3 to 1 veggie oil in the hottest time in summer. 2 to 1 and 1 to 1 ration in the transitioning times. The trucks fuel filters get changed in the 20K plus zone. I believe the success with the filters comes from the 24 hr. centrifuge process. When I first started doing this I only ran it threw the "fuge" for 8 hrs. The filter on the kit truck only lasted 3K miles. I've been doing the blended fuel with no kit for 2 plus yrs. As far as mileage and power I've never done anything 100% scientific as far as testing. I do monitor mileage and know that I get at least 90% + the mileage of straight diesel. I did have that kit on a truck that I raced the 12.0 class back in 2008. Unfortunately I had an engine bay fire before I was able to do the testing I wanted at the track. The kit is on my tow rig now and I won't track test that truck. Its a 5 speed and too heavy. Too inconsistant and hard on parts. I've never done any biodiesel and never will. What I do works for me. At 4 bucks a gallon for diesel I see no down side. I have about a buck a gallon into the veggie oil. I haven't had any mechanical problems yet. It's a messy and somewhat time consuming process but I have the time to do it. Let me know if you have any questions.

Finding the stable source of vegetable oil seems to be the issue. The large chains want you to be insured, and the small stores want you to take it all or none.

I'm pretty sure the large Bio-diesel companies use WVO to process into bio as well as use new clean PPO to process...but I'm having a hard time find evidence they recycle WVO into Bio-diesel.

Anyone know where to find that?

And thanks for the info provided...its helping me quite a bit. I jsut wish I wasn't sick right now, research would be a lot more effective. LOL

Good luck finding any. All sources of WVO seem to be gobbled up by the large rendering companies paying the restaurants as much as $3.00 a gallon for used oil and selfish "co-ops" taking all sources. Restaurant owners think it's worth the price of gold these days as well so when you go and try to inquire about their oil they seem to get all asshole on you about asking.

And how do you know this? That is my question.. what empirical data do you have to support that claim.

Restaurants use to have to pay to get rid of the oil, now they are getting paid for it. Some rendering companies depending on location pay more than 2 dollars a gallon. What more "data" do you need. How much oil have you collected in your life?

Just from a local source...

big food factories use air. They have to have food safe oils in the compressors. I obtained some for nothing. Msds showed petroleum as a main ingredient. Waste oil furnaces burns it pretty good. Gets thick when cold but at 32°, it wasnt gelling yet. They pay to get rid of it.

I've collected none...and that should be pretry obvious. My next question is can you read? All I want is a reputable source of information. And no, your word is not enough.

Notice the price of "yellow grease."

Link isnt working..but I think I can find it front he main page. Thanks dude!!

No problem. I come up with 309 cents per gallon. 40 cents per lb. multiplied by 7.6 lbs (~ lbs. in a gallon of yellow grease.) Hope that helps.

A buddy has been running it for years all on Mercedes motors. At work tomorrow ill ask hi for his website for yea

thank you
