I have been collecting Veggie oil for a few months now from a local cafe. I am filtering it and putting it in a 275 gal. tank. I probably have it about half full. I know if its clean,if you heat it to 160 degrees you can burn it straight.(or so I have been told). My question is,if I force pump it threw a filter and get it really clean,can I add a couple of gallons to say 10 or 20 gallons of straight diesel and run it that away? Or does it have to be processed further? Any thoughts or knowledge from someone who knows would be gladly accepted.

Im in for other replies...
It may depend on what % your mfg says you can run - Normally a lot of ppl run a 5% to 20% bio to normal diesel though..

California, a yanmar guy on here used 100% bio for several years i think and it eventually got his injectors stopped up. I think you can burn straight vegtible oil if you want to after filtered. But for as much fuel as i use i personally would now use more than 25%. Really i would not use any for the 25 gallons or so i use a year of pure deisel.

When you think of the cost of collection and filtering (don't forget the capital cost) I doubt you are going to save any money.
When I think of what a drop in the bucket 130 gallons of diesel fuel is in the grand scheme of things, you are not going to save the environment.
When I think of how bio diesel can gum up your engine, I think it could cost you a bundle.
I would donate the oil you have collected to a commercial recycler and just buy it at the pump...

I was thinking the same thing. I'm fairly uneducated on both, but I have to think that Bio-Diesel is a little bit different/cleaner than used french-fry oil!
Then again, I could be wrong...

I think mixing it would be a problem. You wouldn't want to just dump it into the tank and hope that it mixes. Straight Veggie oil can be burnt, like you said, but usually what is needed is to run diesel while the veggie heats up and then run diesel for a few minutes after you shut the engine off to make sure any veggie oil is out of the injectors.
If it doesn't mix there's a chance that you could get a slug of veggie oil that plugs up a fuel line or injector causing you all sorts of problems. I've seen dealers selling a 5% mix of veggie but I think that's about it.
Another option is to refine the veggie into something that can be burnt just like diesel. It looked like it was more of a pain that it's worth. You need to use water, lye, and race fuel so cost could make it not worth the effort.
The best solution is to have a second tank that's heated. There are companies that sell al the stuff you need. Like I said above you burn diesel until the veggie is hot and then the Diesel again when you shut the engine off. Honestly I'm surprised that Ford (or someone else) hasn't made it an option for their trucks.

Wampum, they make kits for home conversion of used fry oil to a true bio-diesel. I personally wouldn't not be afraid to burn a 10% mixture or a little bit more of a true bio-diesel, but I wouldn't be to keen to burn fry oil in my tractor directly. If you do a google search for bio-diesel kits, you will get all sorts of info.

Looks like Kubota recommends no more than 5% Bio (among other certifications/restrictions). Is cutting diesel with 5% Bio really helping?
For me, the little amount of fuel that I use (or should I say, will use -- my tractor is still on order), I'll stick to pure diesel.
However, I think my farmer friend up the road said he is using Bio in his rigs. I didn't inquire, but I got the impression he was using a high percentage (100% possibly? Is that an option?) of alternative to diesel. He has a lot of equipment and uses a ton of fuel. I'm sure he can justify it as long as it does not damage his equipment.
Me, I probably can't even justify the effort to find dyed diesel... unless it is in town and can be purchased in small quantities.
