I don't use WVO, but I've spent time living on a two-tank WVO bus.

I don't have much to add from what you've heard.. I'd generally recommend a heated system instead of just blending in one tank, but you can get away with blends on these mercedes. However, two tank systems, or at least a heated one tank, are how you do it right.

Dana's plans are good, he's a good guy and well respected.

peace,
sam

I should start blending in the next few weeks. I'm in the process of building Dana's filtration system. My first oil pickup is Wednesday!

I ran my '80 300SD on WVO (pure canola) about 9 of the past 12 months in the St Louis area without a single problem. I ran blends and straight (100% veggie) right out of the tank. The car has always started easily, run smoothly, behaved perfectly.

Before anybody starts in about coking rings and injectors - I am a professional engineer, and understand the risks. I willingly choose not to run a 2 tank system.

Just do it.

My 2 cents.

I've got the Greasecar system in Milwaukee. I've yet to get a good source, and the cold weather seems to be a bad time to raid grease dumpsters. The system has worked, though it can take 3/4 of my drive to work to heat up to 80C. I've been testing it out once in a while on store-bought oil, and it seems to work fine, but I know other systems use electric heaters to make sure it's hot enough. I'm getting a few drums this week to set up Dana's prefiltering, and I'll probably add more insulation on the fuel lines.

I've been running straight WVO since about may on my wifes car and since June on my 300CD. Its a homebuilt system based off of a bunch of other peoples ideas.

I was running fine until the temp dropped into the 30's at night. My cold filtered oil seems to be gelled below 60 or so. Down at 30 its almost solid.

So right now I am running a 50/50 oil/diesel blend. I am in the process of adapting my system to HOH (hose on hose) coolant heating with a coil looped around my filter in the trunk.

You can see pictures of my wifes setup here (http://biodiesel.infopop.cc/eve/ubb.x?a=tpc&s=447609751&f=444600361&m=813100992 ). My 300CD is a little different but essentially the same. Save for the HOH lines. (Was tapping the coolant lines in the engine bay and ran into some problems when I decided to change out the water pump... different thread.. different problem.. but now the 300CD is off the road till I get the coolant system fixed)

I'm not a certified mechanic, but I did stay at a HolidayInn Express last night.

I ran 100% WVO in a two tank system on my old '78 300D. I intend to re-install it, with modifications, into my '83 240D. I made my own heat exchanger and electric fuel heater, and plumbed it myself for about $250. I had no problems with the WVO; to the contrary, it was biodiesel that was plugging filters every other week for me. I was able to heat the WVO to 140-160 F under most conditions in the spring and summer in Denver.

I run 50/50 unheated blend. It runs fine....but I'm fighting an algae or fungus problem. Lots of black gunk clogging the filters.

I was unheated but this weekend I built a heated fuel line. Hose inside a hose using coolant. But I live in south texas so it's probably not going to make miuch of a difference.

My first WVO system was on a '90 Mazda Capella 2.0L diesel. I covered >30 000 km in 3 years on WVO. It had a heated tank, HIH and time delayed return line switching to reduce start tank contamination with WVO.

Late 2003 (Dec 20) I bought an '80 300D w/220kkm. I ran a 50% blend in the fuel tank with a simple coolant / fuel heat exchanger in the engine bay.

Early 2004 (Feb) We bought an '82 300D w/380kkm. SWMBO runs a blend of 50% biodiesel/WVO with a simple coolant / fuel heat exchanger in the engine bay.

In Mar 2004 I bought an '84 300D w/280kkm. I have installed a 2 tank conversion with unheated 20L carboys as the WVO fuel tanks, a Holley Blue electric lift pump, unheated OE steel fuel line to the engine bay with a comprehensive coolant/fuel heat exchanger and WVO fuel filter before the pollack motorised 6 port valve. A turbo boost/Vac gauge connected to IP input allows monitoring of fuel pressures. I "cold filter" all WVO to ensure that no fuel gel problems occur in either my car or SWMBO's car.
