Loneranger,

The drivers put a quart or 2 of what in the tank?

Here is a test.
i mixed 1/2 cup of veggie oil 2 spoon full of gas and 3 spoons full of new tranny fliud in a jar.

the other jar had just a 1/2cup of veggie oil

Put them both in the freezer and left them over night, conclusion the miz of wvo/gas/tranny fluid was full liquid no even sludgy!!
and of course the regular vo was just frozen into fat.

HERE ARE THE PICS!!

This pic shows the mix of vo/atf/gas and the other jar vo. The mix looks red because of the atf.

left this in the freezer over night under ice!!

trying to shake the vo but its frozen solid

this is the mix straight out the freezer and im not shaking it just showing it in its form

and this is me shaking the vo/atf/gas mix

And you are going to burn cold veggie oil in your engine?

SirNik84 · #19 12-19-2005, 02:12 PM

where do you buy your filters? is there an online site?

Well for one the point of glow plugs is to heat the fuel no? and i have a heat exchange that warms the fuel and the copper heater around the fuel filter too.

McMaster.com. Take the time to figure out EXACTLY how you are going to filter before you pick a length, though the bigger the better: more filtering area=quicker filtering and longer service. I use a 14" 5 micron in the bottom of a 5 gal bucket. With a spacer bucket and the collection one on the bottom, its not too high to lift the oil. Drycleaners are great places to get 15 gal barrels w/ a 2" bung if you don't have space for the 55s

I'm just asking as I've not heard of anyone in cold climates running WVO blends. The glow plugs will help it start, obviously, but they do not warm the pre-chambers or the head, so any cold start will not have good combustion. Regardless of the fuel I run, when my engine is cold it's very slow to accelerate; I attribute that to incomplete combustion.

I don't want to make an issue out of it, I just wouldn't want partially burned VO in my engine.

I fill a 60 gal tank with the top cut off amd build a fire under it till it boils to get rid of any moisture in the oil and let it cool. I then pump it through a 20 micron to a 5 micron to a 1 micron filter and into a barrel. Usually burn a mix of about 50/50.

Well, no one else has said anything about SVO, so I'll chime in on it. I am burning clean new veg oil mixed 80/20 with rug and then adding this mixture to my tank 50/50 with pump diesel. So basically running 40% veg, 10% RUG and 50% #2.

Seems to be working great, though mileage seems to be slightly less with the blend than with straight #2...

To answer the original question of the thread I thin my filtered and dried WVO with K1. My blend recipe is

80% clean/dried WVO
18.5% K1
.5% acetone
1% turpentine
Diesel Kleen per bottle specs.

My processor makes ~ 150 G at a time.

I've been running this in my Benz, Powerstroke and Cummins for over a year. Closer to two years in the Stroke. Many, many miles. Down to 18F last year. Start on it, run on it. No extra heating. No extra filters.

When it gets cold (to me cold is at or below freezing) I mix 40% K1. Other addatives stay the same.

The recounting of the alchemy adventures employed in thinning WVO in these Shop Forum pages has been very informative and scary (motor oil guy- Stop! - You are polluting horribly).

Just so there are no additional misconceptions about WVO as fuel I am going to post the specific gravities @60 degrees F:

Diesel Fuel Oil 2D/3D/4D/5D 0.81 - 0.96
Olive oil 0.91 - 0.92
Palm oil 0.924
Peanut oil 0.92

So, WVO at 60 degrees is within the acceptable SG of diesel fuel. The thinner stuff is used for colder climates. From the abbreviated chart it is easy to see that cold WVO will clog and ruin a diesel at cold temperatures. Don't do it! Having said that, heated WVO can be tolerated in a MB diesel quite well, thank you. I know there are polymerization issues with the crankcase oil but frequent changing fixes that. Fouling of the combustion chambers is another WVO as fuel "inevitability." I have not witnessed any clogging or rough idle due to carbonization after 10K of WVO miles. If I was clogging and carbonizing, you would think the engine would "let me know." It runs so quiet at idle I can hear the IP from inside the car. I do add 3 ozs of Lucas fuel treatment to a 12 gallon WVO second tank.

This is an old car (1985SD), a damn nice one but one major repair away from the crusher. Even if I were slowly "ruining" an old MB diesel with WVO, I am getting propulsion without giving money to dictators and Wahaabi murderers. (Sorry, I didn't mean to interject politics into this "mixture" but the rationale for WVO must be fully understood.)

Now, why does my WVO SD run so good. I live in sunny Las Vegas, so the crucial operating temperatures are seldom approached. Maybe WVO is not for every climate. And, I filter. And filter some more. The difference between properly filtered WVO and a slapdash mix can be as high as .04 SG! I can send pictures of my low cost "refinery" to any enthusiast who wants to try it. And I have even witnessed WVO-ers who have procedures that eclipse my standards. To those experts, i would like to hear of your filtering exploits.

Finally, I do not wish to infuriate or demean our Forum purists. You are sentinels and keepers of mechanical knowledge and we owe you a debt of gratitude.

There is no climate "warm enough" to not need a two-tank system and 91 - 0.924SG is not "within the acceptable SG of diesel fuel". It must be heated before it enters the injection system.

Perhaps I wasn't lucid enough. I do use a 2 tank system. I switch over to WVO once the engine is operating temperature. I have seen some very slick one tank systems with heating coils near the injectors, but 2 tanks seems the least error prone to me.

Considering the challenges our cold weather brethern endure, I was suggesting that any WVO system might not be optimal.

Sorry for the confusion.

Huh..... thats funny. Isnt it interesting that I have been running two 300Ds on single tank. One for 25,000 the other for 17,000 miles. Without fuel heaters (but we use block heaters below 35F). Thinned out during winter with kero. No issues other than needing to change out primary filters and give it a little warm up before driving on cold mornings.

Just checked out by a Mercedes shop and given a bill of clean health.

Granted I dont live in Minnesota.

Interesting test....

Shows just how little quantity of 'Gas'/Petrol is needed to keep veggy on the move....
To a certain extent it works pretty well with BioDiesel too, but I prefer to use std. diesel fuel for 'winterising' BioDiesel...

BTW, Dont fancy your coronry-arteries chances with all that fried-food/Processed TV dinners in your freezer!
