[Cummin A Long]

Me and my buddy been trying to run WVO in are trucks..his powerstroke and my cummins but its not going well..This is not biodiesel just WVO filtered running it 50/50 with diesel..anyone ever try this or know if its even possible?I tried it in mine last night and it ran good for about a halfhour then started to pop and miss, it sounds like it isnt getting enoth fuel?any input will help thanks.

 

[mikeshauling]

try reading some info from burnveg.com there is some good info on there.

 

[patracy]

I tried it, doesn't work that well on VP44'ed trucks. The timing piston simply doesn't like the thickness.

i run a diesel / wvo system in my truck i have a 97 12v in my 83 chevy and it runs mint. the secret is clean 2 micron filtered oil and a HEATED TANK AND LINES!!!!! the oil MUST be 160+ degreese before a complete burn willl happen at that ratio. plus at lower temps such as ambient outside temp. the oil has a real nasty habbit of coking up the rings and injectors.

Plus as we all know diesel burns better and lubricates better when its cooler but wvo runs better hot...the two dont mix well so a dual tank setup is better. start and warm up on diesel and change to wvo while running and reverse the process before shutting down to purge the lines of wvo so it wont jell.

you can get away with 5-8% wvo without heating. I really like burning WMO or trans fluid it is easier to mix 50/50 with diesel

well right now i got 5gallons of wvo in my truck and about 20gallons of diesel and still getting a mis and pop when running it...is there anything i can do or am i just going to have to drain the tank.??

 

[BlackCloud83]

i would drain it and let it separate in a clear container then re fill with the diesel. run it for a bit after too on just diesel. try increasing the % WVO steadily each new tank of diesel you put in. start with like 5% wvo per tank ( 1gal WVO / 20 gal diesel ) make sure your oil has settled and been filter with a 2 micron bag ( heated while filtering ) before introducing it into your fuel tank. then you can increase the % of WVO each time you fill up until your engine runs like crap again , that will give you a max % of wvo that can be run. my gm 6.2 can run up to 18% without sputtering, but it is a multi fuel military engine, my cummins 12v i run a dual tank heated setup.

 

[patracy]

Yup, I have/had a dual tank setup with 20ft of heated hose in hose. Fuel temp wasn't an issue as I could get it past the 160F mark. The viscosity is still an issue for the VP44. I'm playing with JetA in the dodge and WVO in my Samurai now though. In a P-pumped truck it's not an issue though.

I looked into this as well. You need to have a seperate system for it, seperate fuel lines, tanks, and everything. It needs to be heated and your engine up to temp before the system will even feed the WVO to the engine. When you shut it down the system will purge itself and shut down on diesel. You start and stop on diesel and run on WVO. You can't mix the two as they will remain seperated in your tank and cause the engine to run funny. There have been mixed reviews on running through the VP44 trucks. The system manufacturers say it is fine (of course) but users have mixed opinions. The tolerances on the VP44 are two tight (IMHO) to make it work effectively.

If you do a WVO system and don't live in Brazil you are going to have to use a separate system with a heated tank and heated lines, otherwise the fuel will be too thick. What did you use to filter it? Does it have any water in the WVO?

Look up my WVO system here. I had it all like it needed. It's just the VP44 can't handle the thickness.

if you run vegy in your diesel tank at no matter what mixture it will destroy it! i worked for fyrbid and helpp design some kits so pm with qs

 

[rdhawk]

We run used trans fluid in our city tow truck for a while it run ok. It was a 89 ford diesel

These are the rules I follow building my WVO system on my 91 cummins.

1. No reactive metals + O2. Reactive metals will turn you VO into unusable filter clogging sludge. reactive metals are copper, mild steel, zink, galvanized steel.... probably bronze as well.

Aluminum, brass and stainless are OK. an exception to this rule is a copper brazed heat exchanger. The heat exchanger wont have any air in it so polymerization wont be a issue there.

2. No natural rubber. WVO will melt it.

3. heat heat heat. WVO must be at 160 before it hits the IP. It is highly recommended that when designing a system, heated fuel lines, heat exchanger, heated pickup and heated filter should be included.

4. Change your oil twice as much as normal. have an oil analysis done on occasion.

 

[weldmachine]

if you do it properly you wont ever need to change oil more then regular

 

[trbizwiz]

for now at least change your fuel filter, see if that immediately helps. If it does you probably did not filter your oil well. If you are going to stick with this set up, go with a 2 tank system as the others mentioned. Try to find a better filtering system. On the diesel side 2 microns is top notch, doubt if bio would ever flow through that, maybe if it was real hot, and well filtered already. I have read that you can buy 10 micron filter bags and you put 25 gallons of fuel in one suspended in a 55 gallon barrel, the clean oil will trickle through eventually and leave most of the crap behind. Then this stuff in a heated tank going through as fine a filter as you can afford to replace regularly should work pretty good.

I suspect even if you dump your tank right now unless you change your fuel filter you wont see much improvement, you may also just need to drain the fuel water seperator. Best of luck, I admire your creative adventerous spirit. I have done a lot of reading about it and I havent the guts to try it yet. Probably wont, but might try making a batch of bio.

 

[Alphawhiskey]

BIG NO NO!!! VP+ non heated wvo= Bad things... Save yourself the trouble. Drop the fuel outta the truck, change the fuel filter. Install a full 2 tank system or run bio. Please dont wreck your trucks by run wvo w diesel in the same tanks.

 

[patracy]

Someone care to explain to me where I failed in my system then since everyone is a subject matter expert here? I had 15ft of the fuel line setup as a hose in hose. Fuel was over 160F going into the VP.

 

[BridelessRacing]

Having run bio diesel and filtered wvo in 4 diferent cummins vp pumps do not like alternative fuel. I now run a ve pump 12 valve in a 03 quad cab this engine has over lots of miles on wvo. I am curently back on no 2 as I am loosing power on CYlinder 1 and 4

 

[BridelessRacing]

A new pump head and plunger and I'm back on 6 cylinders.

 

[diesel6.7]

wvo works, heat, filtration and good fuel pressure are keys... seperate tanks are a must!
