Engine/Transmission (1994 - 1998) Waste Veggie oil Conversion

[TXDSLSHOP]

Has anyone on here converted their 12 valve to run on WVO? I am going to convert mine as soon as I get the rest of the parts together. I am trying to get some input, and see if anyone else has done it. I have looked at tons of WVO sites and they are mostly VW's and Mercedes. I have a guaranteed supply of filtered WVO. Thanks. Jeremy.

It is very wise to take the WVO to the next step and do the titration to separate the glycerine. Then you will have a very good fuel.

I am working on it with a friend. Hope to have some by the end of the month.

You mean transesterification right? Titration sounds like something even more interesting though

Cooker, you are right I used the wrong word. Just swap the two!!

I have considered making biodiesel out of the WVO but I have decided that if peanut oil was good enough for Rudolf then WVO is good enough for me. I believe that as long as the fuel is heated and filtered/dewatered correctly it will be fine. I am trying to use it as a cost effective substitute to diesel. Thanks for your input though.

I saw this on an episode of "Trucks" and thought it was a pretty good idea. They were using a system from "Freedom Fuel", I think. I never could find anything on them but I did find this:

The basic system goes for $2500 :--)

From my figuring on 500 miles a week it would take 4-5 years to pay for it, plus all the time and trouble of making it work, such as going and getting the used vegetable oil, pumping it out, getting methanol, mixing, removing the "sludge" that settles, diposing of said "sludge", and dealing with the fuel, storage of necessities, and a place to house the equipment. I'd say that easily doubles the expense, so that makes 8-10 years.



The first time I spilled 30-40 gallons of McD's finest all over my truck or garage that would do it for me! That's an awful lot of time and trouble.

You should take Fox's advice and stick to Biodiesel. I've fooled with WVO and Biodiesel for over 300k miles, in a couple of different vehicles. WVO is not worth the troubles. Plugged filters, pre-filtering, fuel heaters, dual fuel tanks, fuel solenoids and cylinder carboning are among the long list of problems associated with running it. Biodiesel, while a bit more involved to make, is easier to run than WVO. I ran my '96 CTD on Bio for a couple of years, and 50k miles with no troubles. I'm not brave enough to run WVO in it, considering the price to fix it.

I'm sure some others will offer different opinions... but that's mine.

I have two 12 valves and intend to only try it on 1 for now. I think that I should have better luck on the WVO because of the climate. If the oil is cold it makes a world of difference on how it burns. It isn't hard to heat oil to 160 degrees when the outside temp is 90 or above eight months out of the year. I intend to pre-heat it, and I won't even attempt to run it when it's cold. (January-February) I don't mind taking a risk to see if it is feasable. Thanks for your input though.

 

[JoeBioDiesel]

As long as you've convinced yourself to do it. Here's some advice.

Cold filter the oil through 2-5 micron sock filters before putting the oil in the truck. Any oil that doesn't cold filter should be discarded(or made into Bio).

Make sure your thermostat is good and the engine runs at normal operating temp.

Make your own setup using two 3-way valves that allows you to completely flush the fuel system when shutting down.

I prefer the veg-therm electric heater with an additional coolant pre-heater to reach the 160F temps needed to run SVO. Without the 2 stage heating you will probably have trouble reaching the high temps because of the high amount of return fuel on a cummins.



Have fun,

Joe

I have thought about it and have been watching a farm down the road do it for a few years to a VW rabbit, their old farm equipment, a ford van. What I have seen and heard is that the van died out west, the VW never came home one day and they didn't want to talk about it, then they took their Bidiesel sign down off the barn and baught gassers. I heard something about food that had been presalted. Whoo, that scares me, but good luck.

check our greasecar.com,



they use a heated tank, with a filter, not processing at all.

Biodiesel is different than Waste Vegetable Oil.
