I agree with Rich C,
There is much more to either bio or WVO than pouring it in the car and go. I have a Powerstroke and a Mercedes 300SD. I began making Bio about two years ago mainly because of the cost of converting both vehicles. You need essentially the same processing equipment for either fuel so I decided bio would be economically the best choice. I have since converted the Mercedes with a two tank system because it is by far the biggest user of fuel and eliminating the bio processing time for fuel for the Merc freed up a lot of time for me. I will convert the PSD as soon as a quality kit comes available at the right price. In my experience bio is a good fuel but it does have it's limitations. Ambient temp is a problem and mixing in dino doesn't equal a good solution to me. Below about 30 deg you need to mix 50 % or more of dino to overcome the gelling problem and may need to add additives to keep the diesel from gelling as well. There are no really effective anti gelling additives for bio that are not cost prohibitive to my knowledge. Bottom line is this, the decision as to which one to use needs to be based on your personal situation. Ambient temps in your location, availability of necessary processing equipment and supplies, work area to process etc. Making bio is interesting and time consuming, filtering and de-watering your stock needs to done for either process. In both cases good reliable fuel can be made and used without concern if you do it right. Well made bio or a good two tank system properly installed and set up will enable you run your vehicle with no concerns. The key is both the system and the processing must be done right or you will have problems with either choice.

It comes down to spending money on hacking up the car with a two tank "conversion" or spending the same money and time to get a proper biodiesel processor.
Biodiesel is always the best option of the two. |

Thats assuming you spend the time to make the bio and make the bio RIGHT. There are many stories of people running bad bio that kills injectors and other parts.
If you pick the Bio route, I highly suggest dry washing with purolite or my buddy uses ecopure and has good results. I tried it all, water washing, bubble washing, settling and so on. purolite worked out the best for me. Here is my bio setup v3 (processor, settling tanks, dry wash kegs closest The processor is a open top 55 gal drum It all comes down to how much time you have and how much you drive. In my truck I use so much fuel that I can not even come close to making enough bio to feed it. Just going to work and back I use 25 gal a week. now what about those trips out camping where Ill burn 50 to 100 gal in a weekend? With my svo setup I can spin 30 to 40 gal a day and I usually do 20 gal a night after work before I go to bed! I spend most of my time getting the oil and bringing it home which I would do either way. 20 gal a day vs 20 to 30 a week making bio. Ill spend the money and use svo. here is my svo filter/cf setup in the garage and the CF

Could one simply use a cyclone to drop all the particles out of the veggie oil?? We use them on water here, and get it to 99.8 percent pure as tested by a lab. Not bad from a stinking dugout with leeches, and brown water....

not sure what that is. Are is it like a CF? think of that ride at the fair where you stand against the wall and it spins and the floor drops. that is a giant CF!

This is what a cyclone is... The 2 inch model can separate 200 gallons of water for us an hour... Running the ater through the cycle 5 times... Essentially 1000 gallons an hour...

I wonder if the same cyclone that is uses for water could be used for veggie or if it would need to be reshaped for the different fluid properties ?
Time to give the company a call and see if they will send me a test unit. |

Why? if you have a proper WVO system, what is wrong with it? I don't run WVO in my stuff, (and I only would run Bio not veg) I am just curious of why you think what you do?

Acidity, food fat, the compounds that produce glycerin and viscosity. No amount of settling, filtering or centrifuging will remove those glycerin compounds, which is what causes most of the harm and part of what biodiesel was developed to address.
Biodiesel also doesn't have to wait for the oil to get hot, which means it can be used on short trips where WVO would never have time to be used. That also means you aren't stuck with a blob of grease in your injection pump when you inevitably forget to switch to diesel before final shutdown (everyone makes mistakes). |

Acididty can be changed, and is almost never a serious problem.
If it was the food cooked in the oil would not be humanly consumable. And fats are the compounds that break down during transesterfication to make glycerin. They are not two seperate, distinct things. |
