I have read some horror stories from users of WVO. I read a story where an injector clogged and wouldn't pop, it continually squirted into the cylinder and vaporized the piston. Stories about separation of the glycerine, acidic conditions in the fuel train and onto the cylinders, etc,etc. Any one had negative experience in a 12 valve?

The key to using WVO or BIO

is doing your esearch and learning what needs to be done to do it correct.

if you take the time to learn and read what you need to do then it will work and run fine..

if you just jump into it becasue the price of diesel is up you will probably end up with issues..

OK, first off lets seriously think about this here. Bio diesel is a fuel that is man made within certain tolerances to meet auto maker engine requirements. Now on the flip side, WVO is old cooking oil that is thrown into a dumpster and when brought to temp is highly flammable, not combustible like diesel.

Make your own BIO- Yes

Run WVO filtered- No

Our engines run on fuel that has a given flash point, meaning once cylinder pressure reachs a psi, the fuel detinates. WVO is explosive in at a given temp. If the flash piont of a fuel is changed, you may be working your engine against itself.

I personally have ran filtered and heated WVO in my 03 and have determined that legitimate bio fuel is cool but WVO is a ticking failure waiting to leave you stranded.

That's what I'm feelin about the WVO, C/PRD. The problem for me is that by the time I got to a station that sells bio and back I'd be empty. What is the rough cost on a home brew bio system? My buddy has run his 97 on WVO for about 25,000 now and no problems, but he doesn't care or know what it may be doing. He is cheap and cost is all that matters, until he has to find a replacement truck because his went down in a blaze of cheap guy's glory.He tries to get me to convert, he will sell it to me cheap or I can help out collecting, but I am the kinda guy that wants his CTD forever. i took on a second job for play money for my first gens, but it only gets me to job 1 and back. I am chomping at the bit for some relief but am very skeptical. I believe in running something as it was designed to do, with the exception of a little tweaking and only after others have run trial periods.

Gettin back to the subject, any other horror stories and physically what will the engine tolerate? I'm talkin the breakdown of parts, due to acids and that sort of thing. First gen issues. lookin for real world first hand, first gen stuff.

I run bio in my truck with ZERO issues.. the truck runs better on bio then diesel.

I also have built a 54 gallon tank that I am going to run WVO on..

I have done tons of research on this.. and I have seen and helped others with there conversions..

shoot we have 4 guys in our 4x4 club that all run CTD's with WVO.

it is all in the PREP time withboth WVO and BIO

lye is cheap and properly mixed with WVO will remove the glycerin. The meth is used to delute and increase the cetain rating but not totaly necisary(sp?) in warmer states. I have tried and not had any issues with filtered WVO processed with lye to remove the glycerin. Seems to work pretty well.

ezbiodiesel.com makes a setup that cleans, bubble washes, and dries the WVO. I want to invest in this particular system, but as the goverment becomes wiser as to what we are using that much lye and methanol for you will be signing sheets for the stuff just like suddafed. I think you will also see a rise in issues of dispossal of a hazardous waste (the left overs). I personnaly hate to sink 4 G's in stuff to find out 6 months after I got it that I can no longer obtain my necessary chemicals.

WVO is fine to run as long as you only run it when the engine is warm, and the WVO is filtered and heated to at least 160*F. I have a few tractors with over 6000hrs each running on Veg, filtered to 20microns before it is even put into the tank. The key is finding good clean oil, that is not hydrogenated, and doesn't have water in it.

Yeah the whole clean thing is a bit of an issue. If you've ever been in an alley harvesting WVO it's not uncommon to find the lids off the tanks. So water is almost guaranteed to be in there. And if oil is already at 160*F, what affects does it have on over heating your IP?? I know the VE doesn't like stress or heat. At least not for long.

WVO + lye = soap. (lye + methanol) + oil = biodiesel.
It doesn't matter how hot it is where you live, if you mix lye and WVO, it's still soap. Not thin biodiesel-like soap, but thick, gloppy soap. If you added a little lye to a lot of WVO and let it settle, what actually happened was the soap settled out (or floated to the top) and you ran some really dubious messes of WVO as fuel.

Seems 99% of the VE pump failure threads I read involve the use of bio or wvo.

You'd have to save a lot per gallon to pay for a rebuilt VE...

How many miles before they seem to go? Lack of lubricity? Too many impurities? Leaky seals?

7+ pounds per gallon...

No IP leaks or failure yet but it only takes four or five fillups of the diesel tank to pay to have the IP resealed. Only problem has been a leak from the lift pump from deadheading it but resolved by adding another solenoid valve to send diesel to diesel tank on a two fuel system setup. It is a 15 year old truck and everything but the Cummins will need to be repaired eventually. Only 15,000 miles.
Caveat Emptor !

lets just put it this way I'm paying 4.19 a gallon and see #2 up to 4.59 even around San Francisco but will not switch to bio.

As usual you are spreading bad info about WVO. I have been running it for over 4 years in a 12 valve. I also have an F450 7.3 running on it. Hold off on the FLAMES. Get accurate information before you ever put a single drop of WVO into your outfit. Here is a good place to begin http://www.frybrid.com/index.htm

It work well but MUST BE DONE RIGHT!!!!

What? Can you explain some of this? [laugh]

If you run the stuff without the heat, filtering and water removal it needs youre asking for problems.
You can make biodiesel from it too, but that requires an initial investment in equipment plus a lot of chemicals that fluctuate in price quite a bit.

do your homework before you spend the money and make sure which ever you do is right for you.
