Hi guys i'm sure this thread has been posted before, i can't seem to find anything on it, so im making my own. I have heard of guys running vegetable oil or used cooking oil through these trucks. Can it be done without any mods to the motor, and does it wear out the fuel system faster?? Diesels getting too damn expensive, and i know a place where i can get a ton of used vegetable oil, so if it can be ran, i wanna do it, but i dont wanna wreck my motor either. thanks again

 

Bio-diesel, Propane & Alternative Diesel Engine Fuels - Ford Truck Enthusiasts Forums Have you checked out this page, including the stickies at the top?

 

I have looked at this part, bit its hard to find stories of guys running it through their IDIs. It seems like everyone is running it through the powerstrokes, 7.3 and 6.0. Does anyone know first hand what its like on an IDI and if major mods or amounts of money has to be stuck into the motor to make it run realiably on this stuff?

 

a neighbor of mine made a crude filtering set-up, a tank to go in his bed and a heater run through it. he admiited he was useing oil from a chinese place - they fry sweet stuff, a lot of it - and it screwed up his injectors in his '95 250. I'm wondering if oil from a veggie fryer maybe better?

 

HERE IS A QUOTE FROM DAVE S. FROM A FEW YEARS BACK (not sure if the regulations are still the same but would assume they are i have not heard of any changes)

Diesel and veggie oil do not mix, so the blend is not the right way to go.

Most common is a veggie tank that is heated to run on after warm, regular diesel tank to use to start and stop on. That way the fuel system is purged of veggie before you turn the engine off. The glycerins in veggie oil cause engine damage if the oil is not up to something like 150 degrees before you run it through the engine.

The equipment you need to run it, the road tax issues, and the hastle involved are not worth the benefits in my opinion. Untaxed fuel in an on highway vehicle is a 5000 dollar fine plus costs for the first offense here in WV. 5000 dollars buys a lot of fuel and I average running into three or four fuel checks a year.
Home made bio diesel, veggie and off road fuel are all untaxed fuels.

Drop down to the alternative fuels forum and they can straighten you out on the requirements.

AND THE THREAD IT WAS TAKEN FROM

The guy that processes beef for me runs a veg. oil blend. He blends it 80% veg. oil and 20%, I am pretty sure it was alcohol. Anyway he has a set up. He built a lab. he said he had about 1500 hundred in it. He heats the veg. oil, filters it though a pretty tight filter. He takes a sample and puts some thing in until it turns a purplish color. The amount of liquid it takes to do that determines how much lye he puts in the mixture. He went somewhere a learned about this at a seminar. He was running it three years ago and had been for awhile. He runs it in all his farm equipment, bobcat, and two Dodge pickups. He said the mechanical motor got better fuel milage with alittle more power and his some electronic motor did worse on it them pump fuel and lost some power. His son had over 100k miles on it with no problems. This guys knows what he is doing and he a big supply of oil. He said he did render down some beef fat but it didn't work if it got below about 50 degrees. I haven't been to see him myself for a couple of years.. I had my beef hauled up and back by somebody last year.

Yeh, it is alcohol. He said he about 1.25 per gallon in it.

 

catfish, that is the process of taking WVO and converting it to biodiesel. Basically wwhat happens during this process is a chemical conversion, that takes a lot of the 'soap' out of the WVO.

Bio diesel needs less work to run in vehicles, it can be run in the regular tank without a lot of extra heating etc, but has more work to process.

 

If you do the home made bio diesel thing, the cost would be about 1/3 of what pump diesel is per gallon.

Now figure time collecting oil, processing it, the equipment required, running out to get methanol, possible code violations if you live in town or in a city, the space to do it.

Tell me again how this is saving money.

If I was retired, had nothing else to do with my time, I might consider doing this.
While I am working, no way.

My luck, if I got everything set up, my waste oil supply would dry up as soon as I was ready to start making bio diesel.
So the cash outlay for the equipment would wind up being a negative savings.

Running heated WVO or SVO in the climate I live in, again just not worth the headache, time and equipment outlay.

 

Been there, done that and works like a charm but gotta start and stop it on diesel or once its cold you wont be getting her started again. Don't know if a heat exchanger to warm fryer oil is necessary but its viscosity is night and day different at 70 degrees vs 140ish degrees.

Get some old fryer oil and stick it in a STEEL drum and agitate the drum after a few weeks and see what you get. Your gas tank (probably), some of the fuel lines and injection pump are made of steel and you will notice a polymer buildup. Made me quit.

 

When you switch tanks, everything that comes out of the return line till diesel makes it through the fuel system is putting WVO in your diesel tank.

So one fine -10 degree morning, your engine stalls because Crisco shortening is blocking your fuel lines.

Think abou tit for a second, the lines from the tank selector valve up to the lift pump, up through the fuel filter, over through the IP, then the return line back to the tank selector valve.

Probably dumping almost 2 quarts of WVO in your diesel tank every time you switch tanks.

 

There are ways to pipe your setup to limit the amount of WVO that gets into your main fuel. WVO does mix with diesel for a while. It takes weeks/months to settle out so a little bit in the mix doesnt matter.

I ran my diesel thru the heat exchanger so once the coolant warmed up the diesel would warm up the fuel system.

Truck ran just fine. Never had problems other than a clogged filter once and wondering what the white coating in my steel fuel lines were.

 

Making Bio is not nearly as costly or time consuming as you think. Easy process and most difficult part is just getting your operation up and running. Waste oil in and heat, add methanol and lye, mix, let set, drain off glycerin, done! You can wash the fuel and filter it to get a cleaner fuel but really it is simple! And with current cost of methanol, it is costing a little over a dollar a gallon for diesel!

 

What the heck is wrong with diesel?

 

Nothing wrong with diesel...well except the price and our dependendcy on foreign oil which is ridiculous. I figure if you can recycle something that is good for the environment, saves some pennies, and keeps money out of oil tycoons pockets its not a bad idea!

 

Now don't bite my head off if my information is incorrect, but with the older diesels (mechanical setups), you can run them off Raw WVO without chemically altering them, all you have to do is settle the fat off (gathering from the middle of the trap is what I've heard makes it best)

I'd imagine motor oil would work, using the "Runaway Diesel" effect as my basis of claim, although I've heard of cylinder wall sludge deposits on some lower compression motors, but the cummins, IDI and 6.2L Detroit Diesels haven't had such a hard time with it being a higher compression motor set.
