One needs to don a flaming suit to post anything with SVO/WVO. Fribrid.com or Greasecar.com is a better forum on alternate fuel. Just browse the not so gentlemen like replies in the following post.

anyone know of a source for lovecraft filters?

If the engine is at running temperature then I would not think it is a problem to put SVO in the tank if you are running out of fuel. Similar to adding ATF or motor oil when you need to get to the nearest gas station. The heat from the engine block would be enough to heat the oil to temperature.

I personally suspect that a properly designed and properly installed SVO system will work well and not damage the engine. The catch is the word properly. Too many people try to do it on the cheap and pay for it with clogged filters and damaged IPs, possibly leading to a ruined engine.

the key is viscocity. oil is thick, diesel is thin. there are many ways to achieve a workable viscocity. heat, mixing, make bio-diesel.

people here are 50-50...either haters or believers...best to join a WVO forum for a more "open" discussion. I'm here for MB tech. I go to other boards for WVO knowlegde. You will find many others here on those WVO boards too.

Bottom line, these cars are designed for diesel fuel. Rudolf's original SVO engine long ago was "tweaked" by the industry to burn a commonly available and cheap petroleum by-product, since named "diesel fuel" in Rudolf's "honor". We are not tweaking the car back to the original engine concept so much as we are tweaking the SVO oil to be used in the current version of Rudolf's vision.

During the wintermonths I have collcted around 750 litres of arachide(peanut)oil that had been used for frying. With temperatures below 5 degrees it became solid. When spring arrived I filtered it down to 1 micron....no problems at all....single tank E300 TD W210.

Cheers,
Ingmar

I did it one time just to try it, I bought 3 cubes (when they were cheap) of clear fry oil at sam's club...mixed it with about 10% Regular gas....then dumped it in....so about 13-14 gallons worth, plus 2-3 gallons of diesel that were still in the tank....it ran smooth and normal.....however, mileage dropped, and power output was lower. I then went back to diesel. Pointless in my opinion.

Mileage ( mpg ) would drop with SVO/WVO because the energy content of veggie oil is about 10% less than diesel per unit volume ( gallon or litre ). If all things being equal then the mpg would drop by 10%. I have not read anywhere that anyone using SVO/WVO experienced drop in power.

The car just felt slower on it....it felt slower when I ran a few tanks of B20 too....I could tell the difference when I put good o'l diesel back in.

Peanut oil will work as well as any plant oil. But, peanut oil will solidify at a higher temp then others.

I do not advise single tanking it.

Nay on single tank conversions. Your car would be perfect for a two tank system. I haven't seen any good one tank systems, but I've converted alot of one tank systems into a two tank system.

The WVO has to be to at least 160 before it hits your IP. Check out a site called greasecar.com for more information.

I know it does not happen often but while camping out in the desert I have had 2 occasions to shiver inside of my Sleeping Bag (both time I brought the thin one) at night; but her in CA.
Another time I woke up and found a think layer of Snow or Frost on everthing out side.

Without a heater of some sort, I would suggest you use a 50/50 blend. Don't try WVO unless it is filtered well. SVO should be fine for a test, provided you don't run it straight. Enjoy the aroma.

My 87, in the summer runs straight unheated WVO. If the temp doesn't fall below 65 I'm safe. This, of course, depends on the composition of the oil you burn. Oil with higher melt point fats (animal or vegetable) need a hotter climate to be burned without much heat. Fortunately for me my oil has little fat so I am comfortable running it this way. As the weather cools I will add D2 in increasing amounts up to about 40% in winter. Around here that generally means lows in the mid to upper 20's and highs in the 50's. The car has been run this way for the last 57K miles and is doing well.

Diesel experimented with lots of fuels. Low grade kerosine was used in most of his early engines. The use of peanut oil, often cited as evidence of diesel's support for vegetable oils, was the French government's idea because of the abundance of peanuts in the African colonies. This is how the peanut oil powered engine at the 1900 Paris exhibition originated. Diesel did come around to the idea of widespread applications using vegetable oils before he died. But, the idea that he designed the diesel engine to run on peanut oil or any other particular fuel is not true or at least misleading. He designed the engine, then set about figuring out what fuels were suitable to make it work.

This is from a little book called "Biodiesel" Greg Pahl 2005, and it is consistent with other things I've read regarding Diesel's work.
