Has anybody blended cooking oil into their diesel? With what results? I'm thinking of setting up a tank to filter the junk out of it and then blend it into #2 at around 20% to 30%. I think in the summer time it shouldn't cause any problems. Winter could be bad because it gells at such a high temp. Lots easier than making bio with most of the benifts as fas as I can tell.

 

I did last fall when we got "Katrina"ed on fuel prices... I ran new stuff that was cheaper from Sams Club than at the #2D pump!
I noticed a quieter engine and a better exhaust smell (smelled like Popcorn cooking). Same power that I could tell...
I ran about 3/4 SVO to 1/4 #2 as that was what was left in the tank when I filled up.
I was going to go get some more to check mileage but strangely, Sams quit stocking Veggie oil until the price of #2 dropped back into the current range...

I bought ten gallons of brand new canola oil real cheap at an auction the other day. Now the engine runs smoother.

 

I was more interested in used oil.

 

If you are going to use wvo you probably ought to go the biodiesel route. Most used oil has a lot of salt,spices and other chemicals that need to be filtered and washed out.

 

I have been mixing #2 and WVO for about 5mths now.(75%WVO, 25% #2+ the recommended amount of PS with cetane boost and as high as 85% WVO) I filter it down to 1 mic and run it through a 15 mic Racor Water seperator. I mix 1 gallon kerosene and 1/4 reg unleaded to every ten gallons of WVO. The only problems I have had is that the WVO acts like a solvent breaking up any old gunk and parrafin left in your system. I went through a onboard filter once per tank for about the first six tanks, since then I have been changing at regular intervals. Also I did manage to get a little water past the Racor on a couple tanks but that was easily cleared up with one bottle (treats 10 gallons) to 35 gallons of the oil/fuel mixture. Now I have only been doing this for 5 mths and do not recommend it unless you can afford to pay for the potential resulting damage. These are very prelimnary results. This fall if nothing has went **** up on me I will pull the injectors and let ya'll know what they look like.
I will say this though it has saved me a bunch of money so far. Also the rig does run much quieter and smells kind of funny. It like pooring a quart of power punch down the throat of a rough running rig and listening to it smooth out. Kind of creepy.

 

By the way I have been told that this does not work so well with the common rail trucks. I have read and been told that you do not want to go more than 65% give or take in theses applications. ALso it is imperative that you aquire nothing but PURE WVO. No partially hydrogenated or shortening based oils.
