WVO plus #2 Diesel - Diesel Forum

ford109 · 03-18-2005, 01:21 PM

Can filter 20% WVO be mixed with 80% #2 diesel with out haveing problems? Or do you have to process it before mixing it?

yes just as long as it is filtered real good no problem I haven't been able to yet but I have heard some people say they are running up to 80% wvo it just has not been warm enough yet for me [img]/ubbthreads/images/graemlins/shrug.gif[/img]

I run 50/50 no problem and have gone up to 75/25 still no problem. I did add a in line filter before the pump but other than that no change to the stock fuel system.

What is everyone filtering down too?

I only filter to 10 microns , but the lower the better .

How are you guys mixing? Do you just get down to 1/4 tank, toss in some SVO and then top of with #2? I guess my question is do I have to blend the fuel outside of the truck?

I never premix outside the truck. Usually I run the front tank empty and then put in 5 gal of #2,15 gallons of vwo on top of that and finish filling it with #2 For the rear I wait till its below ½ and then put in 5 gal #2 and 5 gal wvo.

I'm new to the WVO stuff, so please excuse my ignorance.

I have a '04 PSD and I plan to filter down WVO to 2 microns. If I mix the filtered WVO to half a tank of #2 diesel (or bio-diesel) will this mess with the injectors or anythink else in a stock setup?

Basically will 50/50 work or should I go heavier on the diesel side?

It sounds like you have a 6 litre PSD, so I'd start out at 20%...you can always work up slowly, but why risk a problem starting all out with a high ratio?

Sorry for my ignorance. I am new to the WVO, bio-fuels scene and want to make it work in my truck and possibly some farm equipment.

What I have read here are some people “washing” WVO then using it 100% in their vehicles. Others are simply filtering WVO and then blending it with #2 diesel?

If I go to a mom & pop’s Chinese restaurant or to a friend’s deep fryer get their used veg. oil, filter it down below the factory fuel filter micron specs, blend it with some #2 and I can burn it in my truck? Can I do all this without setting up a washer, etc?

I appreciate any info.

I've run 50/50 with no problem, but I think the key to it is mixing. When I fill up I have 17 gallons of WVO in 5 gallon jugs, I use the jug with the 2 gallons in it to start the mixing in. Yes it is a bit of a pain but I only have to do it about every other week. I have poured unmixed WVO in the tank, you can tell it goes straight to the bottom of the tank without mixing, the fuel pump gets a little louder. On the safe side I think it's best to add unmixed WVO after a good drive with a warm engine. I filter down to 2 microns before it goes into the tank.

If just filtering the WVO and mixing it with #2 works, why are people putting all the time and energy into making bio-diesel?

Am I missing something here?

Bio does better at cooler temperatures than SVO. If you live where it gets cold, you may not be able to blend at all in the winter.

JoJon: What filter are you using to get down to 2 microns. I found a 5 micron paper element and anything lower is glass which is a bit spendy it you ask me.

WVO typically needs HEAT to be run straight. Even mixing with #2 diesel, I personally get nervous over about 20% oil to fuel. Until we get a few more trucks with 100,000 miles on a fairly straight diet of WVO, im just skiddish.

Bio-Diesel on the other hand has quite a history of being safe, and lots of backing from both grassroots and commercial ventures. Lots more research into engine wear and the like. Bio-diesel is also not as cold sensitive as regular WVO.

At this point, its preference. I personally prefer Bio-D, but if I can rig my truck up with the FN-74 vegistroke style system, I might be tempted to run straight oil [img]/ubbthreads/images/graemlins/wink.gif[/img]

Two things:

1) When you say HEAT, are you talking about a chemical addititve?, or temperature?

2) With a 50/50 mix what temperature range are we talking about? (I live in San Diego, CA)

I filled a mayo jar with a 50/50 mix and stuck it in the freezer. No gel! [img]/ubbthreads/images/graemlins/smile.gif[/img] This seems too simple. Is there something else that I'm missing?
