I can tell you when they refine crude... I think it's the different vapor points (condensation points if you will) that allow them to extract gasoline, kerosene, diesel, propane, tar, etc. I forget where propane falls but that's the relative quality level from high to low. It merely has to do with how the hydrogen and carbon molecules are laid out. There's a lot more in there too, like cetane, etc.

Someone feel free to correct or expand on what I wrote.

And back to the original thread... RUG and WVO would be OK, I would think to the point where you can reach a viscosity of diesel. Otherwise your injectors, pump, etc are going to start giving you trouble, I would think. But for most engines I think 30% RUG would be excessive (understanding that the MB engine is bullet proof though)

Thumbs up pawo SD and who ever else

This is day 3 and it is a blast!

No concerns for me whatso ever...

The way I look at it, try it and if you feel OK with it stick to it, if you think the car runs funny, after a day or 2; go back to diesel.

You'll know how your car reacts by the way it drives for you.

I'm OK with it;

and if you have ANY interest let me know & I'll explain what to do .....step by step....

I am much interested in all the details.

However, I am also wondering about is the long term effects on everything. Reason Diesel engines is durable because it was designed for Diesel. If you introduce something else into it, it's a different ball games.

I always thought and read that it was invented to run on rapeseed oil....not diesel fuel we use today. but

1 Get a good source of WVO; preferably clean cola colored oil that was not used to fry any meats...fish is OK....

2; Get some pails to collect it...clean well

3; Filter ; alot of people use 5 micron filterbags;;(search filterwvo) I filter into a 55 gal drum through a bed sheet folded over 2X and supported by chicken wire ...

4; Mix 1 part RUG; 4 parts filtered WVO; 2 oz of Acetone; 2 oz. of diesel cetane booster; MIX PRIOR to adding to tank...

5; buy extra fuel filters 1 each you may want to begin with a new Primary filter ; get a clear one...to seee through....have an extra in trunk at all times...and an extra spin on...with tools to do a change...phillips head and a 15/16ths wrench or wrachet...

I have a 300D-T but I got this combp from Matt300SD here who has run over 6K miles in his 300SD....

Good luck ....

I know diesel isn't flammable at room temperature, would a mixture of 20%RUG80%WVO be flammable ? What if there is fuel leaks on the engine with this mixture spilling ?[/QUOTE]


Well I can tell you this 20% R.U.G / 80% WVO.. WILL NOT LIGHT WITH A MATCH. How do I know?... I tried it

Diesel/WVO blend is not a good idea. The WVO causes the WAX to fall out of Diesel. Thus leaving a SLIME coat in your entire fuel system. Its ugly I dont recommend it, CLOGGING EVERYTHING!!

THE MOST IMPORTANT THING TO DO IS FIND GREAT WVO...NO FATS OR TALLOW AT THE BOTTOM!!

I would like to learn more about this wax issue.... Although I have done a fair amount of research - mostly(but not all) towards a 2 tank system. This is the first I have seen it.

I am curently running a 25% blend WVO/Dino and do not plan on going any higher.

Thank You

Stephen

I'm running about the same blend as you. This would be a "northern climate" blend.

The hazard of WVO causing wax to separate from the Diesel fuel when the two are blended together was brought up on the infopop/biodiesel forum by a real unfortunate guy who had this happen to his Ford 7.3 litre. As I remember, he was running 60% WVO, and did a LOT of driving, and his truck was essential to his job. The wax gummed up everything and left him stranded.

I suppose the amount of driving doesn't matter- if the wax is going to separate, it would happen in the tank, unless fuel agitation caused by motion is a factor. The fact that he was mixing considerably more WVO than Diesel may be a big factor- we're using a lot less, so it may be a lot less likely to happen.

It was recommended by someone that naptha fuel (the old fashioned Coleman camp stove white gasoline) readily disolves this wax, so it should be part of the mix. I have taken this advice and use 1 litre of naptha for every 16 litres of WVO. I am using the naptha instead of RUG. The acetone in the above recipe would provide the same benefit I would think.

I am sure that nobody knows for certain yet all the facts about the wax separation. There are other concerns hotly discussed on WVO forums also that I am concerned about for long term use. One is that WVO contains stuff that simply cannot be filtered out- mainly starches, sugars and acids associated with whatever was fried in it. This is not just of concern to blenders- in fact it is more a concern to those running 100% veggie. Some say this stuff will solidify on the injectors and piston rings because of the heat and pressure (words used- "coking", "polymerization").

For me it's still science. I'm doing it, but in spite of the suspected risks. And the risks are still "suspected" at this point. I don't think anybody can say with absolute authority that WVO is dangerous to your engine because...

For me, it's been three months, several thousand miles and so far so good. But this by no means eases my mind that WVO is absolutely safe.

Just curious, what is the purpose of acetone in the mix? Acetone is pretty nasty stuff and is hell on plastics.

I have done a test with Diesel 20%/WVO 80%. I poured the blend in a glass and 5 weeks later the Slime/WAX reared it UGLY HEAD!

Regular Unleaded GAS ... "R.U.G" 20% & WASTE VEGGIE OIL.. "WVO" 80% does not seem to have this problem

Make sure to add Power Service Cetane Boost. WVO has lower cetane value the Diesel.

Not True..Only some plastics.........Most Acetone is SOLD IN PLASTIC bottles "nail polish remover". Plastics made for fuel systems are not ruined by Acetone.

At 2 oz. "no more" to 5 gal. of rug/wvo blend there is NO PROBLEM with eating up your fuel system. I have seen a nice gain in mpg by addind Acetone to my WVO.

Uhhh... OK. Don't try it with styrene plastics.

So the purpose of the acetone is to improve the MPG? How does that work exactly?

HUH!!!!!!!!!! STYRENE PLASTICS

NEVER saw that used in MODERN DEISEL FUEL SYSTEM

What you think your float in your tank is made of STYRENE? Wrong again.

Whatever you do Palange DONT USE Acetone..It will ruin YOUR entire fuel system and YOU will see NO improvement. lol

Just wanted to share this with the forum at large. I know it sounds silly and I am not a ploymer chemist, but I would like your input on the topic.

I got off work this morning at 3:00am PST and started the 54 mile drive home to Visalia in my Mercedes-Benz Turbo Diesel. Along the way I discovered I was very, very low on fuel. I quickly calculated my fuel capacity/consumption based on miles driven since last fill-up and concluded I was 12 miles short of the fuel required to reach my destination.

This matter was further complicated by there being no diesel available along my route at this time of the day.

I stopped at a local 24 hour meat market in a small, farm labor community. I purchased a gallon of fresh vegetable oil to complete the trip. I drove the car to within 12 miles of my destination and added the single gallon of vegetable oil.

By my calculations, I had less than 1 gallon of fuel remaining.

Based on past experience in the military, I knew that diesel engines are like vultures in that they will run on virtually any flammable substance. Home Heating Oil, Weed Oil, Jet 'A', and Cleaning Solvents will all serve as an acceptable fuel source.

What I was not prepared for was the tremendous increase in power that I experienced.

Keep in mind that I drive this car 108 miles a day, each and every day of the week, so small changes are readily apparent and the increase in performance was unbelievable.

Obviously, the cetane rating of vegetable oil is somewhat higher than diesel fuel, but this made me think about the possibility of using it to retard combustion in a gasoline engine.

Even with 1 gallon of vegetable oil to 17.5 gallons of diesel fuel, the performance increase is apparent. Additionally, the noise of the combustion process is markedly quieter than it is when burning #2 diesel fuel.

Interesting...Robert

My first clue that I am clogging a filter is that I feel some "surging" during acceleration.

I have run WVO/diesel blends many miles with no wax problems. WVO/RUG is my standard blend and favorite, up to 30% RUG in winter on the Gulf Coast. Near 100% WVO in summer.

I like the primary filters that catch the particles on the outside of the element if you can find them. I blow-out the primaries and use them over and over.

Used motor oil, etc as fuel is another thing, another set of problems and another discussion for another thread.

Dude, did someone crap in your Wheaties this morning? Or is there some other reason for your juvenile comments?

I was merely curious as to the purpose of an unusual ingedient in a wvo mix. I figured someone might know the reason. Obviously, you don't or you would have explained it instead of smarting off.

Maybe there is an adult on here who might know the answer.
