I am interested to hear of everybody's experiences in using alternative fuels in their diesels. I have been toying with the idea of converting as well, but have had little time to maintain my cars much less convert. Anyway, I recently read of a number of people just putting the veggie oil straight into their normal tanks and running business as usual.

Being that I live in the desert, this seems like a good option for me as the veggie oil would stay plenty warm regardless of time of day. Is there any reason I should not try this? If the car does not start in the morning, I do have spares...

running B100

i run B100 biodiesel in my 80' 300D

also we just sold our 4runner and bought my wife a 2005 Passat Wagon TDI that is running its first tank on B100, and everyone hereafter, on B100.

Justin at http://www.Greaseworks.com can sell you kits to change out your older than 95' hoses to synthetic viton hoses. Biodiesel can degrade the rubber in older hoses, but even then it only happens to some, you can just monitor it if you don't feel like changing them all out. that's the only change. the kit with all the Viton hoses for my 300D was $80. my mechanic is putting them right now.

Biodiesel is becoming more widely available with new stations opening monthly pretty much in every major city except boston and la because of CARB.

to me - biodiesel is the only sustainable solution on the immediate horizon. i also have an electric bicycle made by Giant that i love, but biodiesel for auto transport is the only thing you can do right now that is 100% sustainable, fun, and works with both old and new technology.

i would have considered a gas mercedes or a gas hybrid that took flex fuel, though i probably would still have chosen biodiesel, if there was even one station in seattle area that carried 85% Ethanol (E85) that can go in flex fuel cars. Biodiesel is fantastic and the positive all far outweigh any negatives.

i have chosen against dealing with veggie oil because it you have to filter it, and that just is a slow and messy process. most restaurants just have it sitting in 55 gallon drums with bits of chicken and french fries still floating around in it.

you can buy it prefiltered from some greasecar enthusiasts, but then you might as well just buy biodiesel itself.

Unfortunately there is no station nearby that sells biodiesel. That leaves only veggie oil for me...

if you are going to be messing around with 55 gallon drums anyway (you could have biodiesel shipped pretty easy to you in 55 gallon drums) then i agree that veggie oil is pretty amazing. it would be fun to do, check out http://www.greasecar.com also -- i think they discuss the ramifications of trying to run it straight in your tank without putting in the auxilary vegoil tank.

grease

I run 100% veggie oil in my 300d and have many friends around town that do the same ..
I just pour it straight into the tank ( after filtering of course) and have been running that way for about 2 years.. I also plan to run my boat (twin MB diesels) in the same configuration
In the very short (and mild) winter here in FLA I have to run an inline heater

wow! can you add something about your experience with dealing with the used oil, your sources, if its messy, what you do to keep it from being to messy, etc.

cheers!

p.s. love your boat project site. i have a sailboat running on biodiesel also - think i'll add it to my profile

Jason,

How do you filter the VO? I was thinking of making a rig with a self-priming 12v pump, a water seperator/filter, and of course hose with an intake tube and screen attached to the end. I could transfer the VO to a temporary tank for better filtration in the garage later.

WVO power!

its a bit messy when you suck it out of the collection tank outside restaurants, which I do from time to time but I have an old ford pickup with a flat bed and a couple 55Gal drums mounted to it.. so i dont really care if I drip a bit of grease all over it.. However the majority of the oil I use is via a systemI have setup with a local chinese restaurant where they drain the used cooking oil into the containers the new oil comes in, then when they refill, they save the containers for the next oil change, fill them up and then they call me and I pick them up.. they are pretty nice ( the containers) .. 5 Gal pails with screw on lids and carry handles. With this method you could pick them up in the nicest of cars in the trunk.. (maybe a bit of plastic tarp down first, just in case)

but for my pickup and filtering mechanisim, I use marine baitwell pumps (the four piston chamber variety) they are self priming, fairly powerful, and the grease does not bother them too much. I pump/pour the raw oil into the first of three drums, thru a stack of fine screen to get the big chunky bits, then pump into the second drum thru 30 micron racors, then into the final drum thru 10 micron racros, and before it goes into the car/boat/tractor/engine driven welder/truck/whatever it goes thru a set of 2 micron racors.


I am currently shopping for a 99 E class turbo diesel or a 96 non-turbo E class to put the wife in..and cannot wait to get rid of the gas sucking 2004 ford..then I will be all diesel ( er WVO.. ) then the collection and processing really starts to pay off..

That's quite an elaborate setup. I thought 10 microns would be adequate for WVO use. Is this not the case?

I was kinda thinking my truck would be good for all the oil gathering as well, since I only really use it for home cheapo runs.

I hear you on the 210 chassis diesels for the wife. My wife and I were giving serious consideration to this one that Mecedes Benz of Tampa had on e-bay (they might still have it). It was a beautiful black on black '99 in excellent condition and low enough mileage to still qualify for the warranty. You might want to look into it.

I have a 1985 300D with 240,000 miles. The last 3,000 miles have been run on 100% biodiesel. I also have a 1999 E300 with 58,000 miles. The last 1,000 miles have been run on 100% biodiesel. This fuel is wonderful. The only smoke is a little white smoke for 10-15 seconds from the 1985 300D from a cold start. The 1999E300 will not smoke at all. Both cars start quicker using biodiesel. I live in northwest Ohio and I know that I con not use 100% all year round, but plan to use as high of a percentage as possible. The only downside with biodiesel is a very slight power loss. It is hardly noticeable in the 1985, but it is noticeable in the 1999. I highly recommend this fuel.

i'm in the process of converting a 1980 300D to run WVO. it's a 2 tank system with custom steel tank, HOH heated lines, separate veg and dino filters, shared lift pump, and 2 three-port solenoids.

ncofmbd,
Do you use the conversion kit, or just the same fuel system, with b100?

bumblevee,
No "conversion" is needed to run B100. Both cars have over 4,000 on B100. However, I did need to replace the fuel lines between the injectors, the incoming fuel line, and the return line on my 1985 300D. These lines were nearly twenty years old and had been exposed to hours of heat cycling which degrades many things over time. The fuel lines on this car at the tank are fine which tells me the lines that are at risk to high percentages of biodiesel are line with age adn heat exposure. I tried many types of materials for the fuel lines, but the onluy one that worked is the one that has been recommended which is Vton. You can purchase Viton at McMaster-Carr; they are online. Viton as a material is saltly in price, but it works very well.
My 1999 E300 runs fine on B100. I have found some writings that suggest that Mercedes began using fuel lines more condusive to biodiesel back in the late 1990's. In warmer weather I seldom wait for the glow plug light to go out on this car before I crank the engine.
Just try it, you will love it.

jfraley, did you do any converting on your 300D?

After reading your post, it sounds like no conversion is needed to run grease. Any of your friends that run grease have an SD like mine? If so, please ask if they converted anything, thanks.

I am in LA, California and paid $3.49 this morning for diesel. A station had it for $2.99 on Monday, up to $3.19 on Wednesday and $3.29 by Fri.

300D/300SD - plan to convert

Hello, I am currently in the market for an early-mid 80's 300D/300SD with plans to convert to veggie. Fortunately my roommate is in the biodiesel business here in California, so I can buy veggie off him for $1.50 per gallon. I still remember the day, only 5 years ago when Regular unleaded dropped, for a few weeks, to a low of 75 cents per gallon, in my hometown of Kansas City. These days are gone, and I look forward to shifting the power structure of the oil empire into the hands of the people. We'll have to do this one car at a time-- and it's becoming more and more viable each day. Running veggie oil doubles the life expectancy of a diesel engine because it is more lubricative, and I hear these Mercedes' are built like tanks, so I figured it's the best way to go. Anyway, cheers to all you cats going VEG.

Right, I am not sure that a "conversion" is necessary. (See jfraley's posts above) I am imagining that first tank of free grease with no conversion whatsoever.
