With the price of fuel I like the idea, I am sure it will help with lubing the fuel system as well, just don't want to add too much at one time so for a 38 gallon tank how much can we put in there without looking like a locomotive and is it legal?

What in gods green earth are you thinking of ? My daddy used to burn his used oil in his first generation diesel pick=up. If anything the latest is new two stroke oil at 60-1 for the high pressure ulrta sensative coomon rail electronically controlled.

There is 2 ways to make your money in this world
With your back or with your mind.
One pays more (mind - for the most part)...
One gives more satisfaction (back - for the most part)....
To each his own...
Probably just ignighted the flame thrower

wow....
ok then,
so there is the possibility of increased fuel economy by burning your old oil in combination with the fuel? Interesting. I had read somewhere about the 5% mixture which does equate to about 1.5 gal in a full tank. Anyone ACTUALLY doing this with a 3rd gen? What are your results? How many miles has this mixture been burned?

Just got 13 MPG towing two trucks weighing 8K on a 7K trailer this weekend, 15K gross. Running 65 MPH.
As far as the dude from up north that considers himself a yuppie because he drives a CR diesel - get real, you most likely have a 3/4 ton with leather seats. I use my truck lightly compared to most real truckers and I have had mine less than a year and have very close to 40K on it. That is nothing to most that haul full time. I have also had it at 26K gross so please don't try to tell me how to use my truck. When you get a real truck that can pull some weight and you actually use it for hauling please feel free to contact me. With a FASS system it recirculates the fuel a number of times before it even enters the injectors and goes through a much more thorough filtering process than a stock fuel system so I am not nearly as worried as someone might be about impurities. Right now with fuel over 2 bucks a gallon I will look at ANYTHING that I can put in the tank to save a few bucks when I am hauling, better in my pocket than out the tailpipe!!

Barrett_Fodder- Any increase in fuel economy you would see would be due to faulty math. If you don't take the oil into account, your fuel economy looks better, once you add the oil into the fuel used things go back to normal. Real world example: Put 13.6 gallons of diesel and 2 qts of oil in my truck friday. Trip odo said 215. 215/13.6=15.8 - wow! 215/14.1=15.1 - oh, back to normal.

wanna... good way of putting it. I guess though if the oil is free (which it is as waste anyway) then if it burns with no problems or damage thats at least 3 free gallons of fuel i can stretch out over a few tanks of diesel... something to consider anyway.

I have no idea if this works but I saw it in a magazine advertisement.......get used fry oil from restaurants and filter it with whatever (I think they used a cheesecloth in the ad) and then pour it in your tank. I'm not sure of the ratio they used. The ad said you can usually get the stuff for free. The only problem mentioned was the hassle factor of retrieving the oil from the restaurants at the time when the restuarant wants to discard it. I think the ad also added an additional filter system on the truck. Sounds like your CASS system (whatever that is) would suffice.
Does anyone do this? If so, got any tips?

Used cooking oil is a good thing, you can get your family feed and fill up the tank at the same time. You can also add jet fuel, kerosene, gas, mineral spirits, denatured alcohol, Jim Beam, perfume, lindseed oil, deck preservative, oil based paint, anything that will burn (even sugar) will go through these engines no problems at all. After all they are CTD's. Just use chicken wire to get the big chunks out and let her rip.
Make sure you have AAA. Your are gonna need it.

Lot more involved that that. Used fryer oil is often used to make biodiesel, which can be poured directly into the tank. However, a couple of chemical reactions must take place before used oil becomes biodiesel. Do NOT just pour used oil into your tank, as it's NOT just a matter of filtration to get usable fuel. Some engines can be converted in some way to run straight vegetable oil. I don't know what that entails, nor do I know if the later cummins engines can be converted. All I know for sure is that you must not just put used fryer oil (or even unused) directly into your tank.
Search for biodiesel, both on this forum and on the internet. There's a ton of info out there on it.

As I said before, it either is used one of two ways. On hard pulls the engine devolops a little more power, but on light runs, it converts to better mileage.
There is no difference in smoke, and/or filter getting dirty.
