bio-diesel or waste Trans fluid - Diesel Forum

Hello again,
I have a question and hope you guys could help.
I have a good supply of WVO and have started making micro batches of Bio and this is going good. Here is my delima I can get a almost endless supply of Trans fluid.
Would you stop the bio production and use the trans fluid or can I use both?
What are your thoughts.

My understanding is that you can't use both. WVO and any WMO product when mixed produce a glue like substance that fouls your entire fuel system and turns into a porcelein like product when burned. If you have an unlimited supply of transmission fluid, that is where I would go. But then again, I use WMO so listen to what others have to say. Just stay away from mixing the two.

Good info on not using both. Pretty much a no-brainer. All you have to do with the transmission fluid is filter it. Not a lot of labor in that. A friend has been using tranny fluid for years in his 7.3. He says he has to mix more diesel with it in the winter months. Hey, free fuel....I'm envious....

Ok, Once I stop using bio-diesel . How may tanks of diesel to flush the system? Any ideas?

I don't know on that one.

I wouldn't bother flushing it. It'll mix and get run through the engine fast enough it won't make a mess in the tank.

You could run it near empty, then just switch to your new fuel.

Blind Driver is probably right . Just to be on the safe side I would run a tank of D2, change the fuel filter & then run tranny fluid.

If you have a good supply of WVO coming in I would NOT give it up. I would keep collecting it, put an add on Craigslist & sell it. If your tranny fluid supply ever dries up you still have WVO coming in.

You have the best of both worlds. Don't give either of them up.

After you run the D2 through it, be sure to change the fuel filter.
