refined peanut oil fuel

About 6 months ago; my parents started refining used peanut oil, and have turned it into fuel for their diesel trucks. They are using it in an old nissan and they are also using it in 98 dodge; they just in the nissan have used about 15 gallons of it so far and I think I remember my mom saying they went over 600 miles on one tank which I am not sure how much the nissan holds, I think the dodge holds 20 gal. I wish there was a way to convert my mini van to diesel.

The original Diesel engine that was built by Desel was made to run on Peanut oil. When they found that pertiolum base oil was cheep they changed to what we call diesel.

The key to biodiesel is a reliable source of free oil. Key being reliable... and free...

Just curious--Did they make true biodiesel by a chemical conversion process?

I racked up all most 8000 miles since last March, running a veggie oil blend in my Chevy 6.5 diesel truck.

That's what I do, blend it. I get free used veggie oil from the cafeteria at work. I pump and double filter it through two 5 micron house filters and then dump it in my tank 30% oil to 70% diesel. You can safety go 50% but anything over that you risk coking the injectors or worse, the rings.

I'll ask them how they are doing it; all that I know for sure that for the last 8 months they have not had to buy anything to run these two trucks. I know that my dad also gets his oil from the cafeteria at work, I also know just from watching that they filter it through several filters. They use an old pillowcase, then they put it through an nylon and then through to other filters. They are going to fix my washing machine that broke as they want to modify it and use it in some part of their process. I want to say that they are running the trucks on the straight peanut oil, but they may be mixing it with some diesel. I mainly post this to let people know that it is an option and my parents have mentioned seeing if their diesel generator will run on it as well.

No, it sounds like they are processing the oil into biodiesel. It can be put into your diesel vehicle 100%. The only drawbacks I found while looking into it were the cost of building the processor and the constant need for methanol (20% by volume of oil) and lye.

It sounds like they are wanting your old washing machine to 'wash' their bio in. It is basically misting water over the biodiesel to further purify it. The water works it's way down throught the bio, taking any remaining contaminents with it to settle at the bottom.

I run my trucks on biodiesel that I convert from used veggie oil. It costs me about $1.15 per gal. So I tried running the oil straight. I twas a pain in the butt in cold wx. and I gave it up. It must be heated to 170 deg. F to burn cleanly. The way that is done is with the engine coolant and heat exchanger in fuel tank and heated filter head. That involves a second tank to start on petroleum diesel oil and get the veggie oil hot. Then at shut down run on petro fuel to purge the lines.

.................Some say it works great , some say it needs to be mixed , personally , I'll keep purchasing Biodeisel from retail sources so I don't have to worry about clogged fuel filters or sitting on the side of the road on a 20 degree day with the wind howling . Not my idea of fun . , fordy:cowboy:

I run a mix of 50% #2/45% WVO/5% gas. Gas is used as a thinner so it will flow the same as #2. There's a guy in MN that raises 200 acres of sunflowers for the oil. He powers all his equipment with it and has a crusher and also does it for neighbors. I was going to biodiesel, but they are paying $3.00/gallon for WVO. I may eventually put in a two tank system, which if you buy your parts seperated instead of a kit will be less that half the price.

They are mixing it; but they are working on trying to do the straight oil. I so wish my mini van could run on this; even with gas at 1.97 in my area I spend 50.00 a week to fill up.
