i have been told that vegetable oil with an additive will work in diesel's is that true.

Needs to be very well dried out of all residual moisture and filtered. I would recc. waste vege oil at a small percentage first...rather than 100 percent veg. No need for any other additives needed, but over time who knows what ill effects it will have. Others here have used WVO with promising results.

Moved to alternate fuels section! ;)

If you make your own WVO from what-ever source, you need to clean it.
Never use unknown WVO in your vehicle.
Some WVO people say theirs is clean, but they have only filtered it.
Particles, water, and acids needs to be removed.
Filtering only removes particles larger than the filter size.
Settling can remove most of the water, but some remains suspended.
The suspended water may also hold acids, making it difficult for it to settle.
Some people spray a fine mist of water over their filtered and settled WVO in order to settle out the remaining suspended water and acids.
Some people use a centrifuge to clean their WVO. It cleans everything.
I've seen a centrifuge made from a kitchen juicer, such as an Acme.
The eBay prices have gone up with this new use.
Google "Acme juicer centrifuge WVO" for more info.
Using WVO requires some mods to your vehicle.
WVO is thicker than diesel, so you need to thin it, so it will move from tank to injectors easily and so injectors can spray it properly.
Bad injector spray pattern, coking results and your engine wears out fast.
With WVO you need to change you oil more often anyway, because you get more coking than with dino.
Heating the fuel lines, especially the injectors lines is often used.
Some people blend their WVO with other fluids such as RUG (regular unleaded gasoline) to thin it.
Some use a combination of both heat and blending.
The colder the weather, the more heat/blending required.
IMHO WVO is the way to go if you are a DIY'r.

With the warmer weather, I've been putting about 5 gallons per tank in my truck to help out with the gas prices.

Go to Greasecar.com and they have kits and all kinds of info on burning and converting your vehicle to burn WVO. Good luck

thanks

Check out the post above.

Talked to a person at Diesel Injection Service here in Cincinnati recently, and asked him about using some vegetable oil in these trucks, and he said it is not a good idea, something about not being clean enough. I did not go into more detail...

As mentioned your WVO must be clean and dry. I built a centrifuge cleaner, check out this thread http://biodiesel.infopop.cc/eve/forums/a/tpc/f/159605551/m/2001011761
It was a bit expensive, I probably have about $700 in mine. It can be built cheaper, probably about $4-500 but if you process about 30-40 gallons at a time it will pay for itself in about 4-5 times (or about 4-5 weeks) I have just started and just finished my second batch of 30 gallons so I have saved about $250 so far, pretty good investment. I am running a blend of 75%WVO/15%diesel/10%gas and it runs great in my 6.2. I also am using coolant heated fuel lines and filter so after about 5 minutes the oil is warm. I really can't tell any difference in driving with the WVO except the smell. My daughter got out of the car the first time and "Dad, I smell burgers" I told her it was the car, she loves it!
Let me know if you need any more information, I only have about 500 on WVO now but plan on alot more.

Looks like Greasecar only has kits for trucks up to 1999 and earlier?

Thinking of doing a Grease Car mod to the 99 Burb but still nervous
about the optical sensor in the pump being damaged by hot oil.

Put 45K WVO miles on my 99 burb before I sold it no issues. If you clean your VO properly you will have no issues with the optical sensor. They run on red dyed Dino. Also stand by on the 1999 kits Greasecar will have a kit for the D Max real soon. Been running mine for 35K miles.

what about diesel secret does it work like they say

what about diesel secret does it work like they say
Here is the deal:
I did do the DSE thing, works great if and when you got good oil. Meaning frying oil that is peanut, soy and or canola oil.
If for some reason the restaurant starts to switch the oil and uses liquid shortening or other sheat cheap frying oils that are hydroxiganeted or transfat. You're up the creek without a padle, just like me.
My cummins freightliner work truck is down and so is my d-max.
Allready cost me over a 1000 in repairs and towing not to mention the loss of not being able to conduct business.
If you go bio, spend the money and buy the correct set up.
If you're trying to go the cheap route it'll cost you more in the long run.
I shure learned my lesson.

Just my $0.02 worth

any more question's? PM me

What is your favorite source for WVO and Biodiesel fuel lines?
