I have tried reading up on using WVO, pros and cons and to be truthful, I am not sure what is accurate and what is BS.

I work with a guy that swears by WVO. Runs it exclusively in his Volvo and some kind of mixture with a heater in his F250. Seems to go through alot of fuel filters though

What I really want to know is will it work in my truck in Texas. Do you run it straight or do some sort of mixture with regular diesel. Is it difficult to purify?

Does anyone on this board with a sililar setup as I have use it. What are the results.

What are the pros and cons?

I know that I am asking alot of questions but most of the stuff I have found is quite simple over my head.

Any help would really be appreciated.

In my experience, you'll never find the "truth" about WVO, just lots of opinions. Everyone seems to have different experiences with the stuff, particularly because there's so many different qualities of oil, ways to pretreat/dewater/filter oil, and different engines react to it differently.

Will it work in your truck? I'm not going to tell you that you can do it and not run into any problems at all. Theoretically, it should work in a Dmax, provided the temps are high enough and the quality is good enough. Some people mix it with diesel, others modify their vehicles to add another heated tank specifically for VO.

Read through some of the other threads in this section, particularly the "How to run yellow grease as a fuel supplement" thread on this board.

Also, I have found some really good infomation on the Frybrid forums - go to www.frybrid.com/forum/ and just do a search for "Duramax." Frybrid is a company that makes kits that allow diesel engines to run on 100% svo, and he's about to release a kit specifically designed for the Duramax. His forum also has info on different methods and setups for filtering/dewatering VO.

Read through that stuff and let me know if that doesn't help answer your questions. I'm no expert, but I've been doing lots of research on it lately, and experimenting a little bit (more with biodiesel than wvo). I'm in Texas too, by the way.

Not in my Duramax!

I am currently running 25% WVO blended in. I put an additional water separator/fuel filter right after the fuel tank. So far the truck runs great. I bled the factory fuel filter last night to make sure I got all the air out after my auxillary install and the blended fuel is the color of urine. I filter the WVO first through a paper towel and then through a coffe filter before I put it in the fuel tank. It looks like honey (color wise) after filtering. I'll keep you guys informed on how it goes.

From my reading, water separator/fuel filters do a good job of removing water from diesel fuel, but DON"T work very well on VO.
It seems that the surest way to dewater VO is to filter to 10 microns, heat it evenly (no convection currents), let it set for 12 hours, and then draw off the top only. http://www.frybrid.com/forum/showthread.php?t=1134

Guybb, I'd recommend you do a frying pan water test to see how much water you're putting in with your VO. Some VO is dry, and some can hold lots of water that you can't see. It all depends on your source. Dilligent testing and making sure you're putting quality oil in is the key to success/failure in this experiment.

By the way, MannyTranny, not in my Duramax either! At least not yet. I wouldn't put anything in my Dmax tank that's not completely dewatered and filtered to 2 microns (I don't want to mess up my brand new engine - it's still breaking in!). I'm sure it can be done, with a good oil source and a nice filtering setup. I'm just not there yet. Older diesels and tractors are a different story though...

I wouldn't run it in my dmax either. The ECU is cooled by the fuel, and I can't imagine running hot oil through it would do it any favors. I know it has been done short-term, but not sure about long-term durability. I have been running oil in my 87 MB for about 35,000 miles, and if nothing else it has taught me I am dang glad I learned the craft on it rather than the dmax.

When I pick it up it is scalding hot as this is the way the sub shop changes it. So, they already did the boiling part for me. Pretty clean stuff too
