I yi yi... that's no good.

Mrs Notfarnow is pretty patient, and WAY cheaper than I am. She'd wear two pairs of socks and 3 sweater before she's allow me spend $750.

But then again, anything's an improvement over the Samurai. You need a raincoat on INSIDE that thing.

You don't live in Oakville.

I think this is the key.

This supplements its primary use, not replaces it (as ethanol does).

Ha! No I live in Rothesay, and for the most part they don't take kindly to wingnuts storming around in $chitboxes. I can't help it though, it's my nature

Exactly. There is no "magic bullet" energy source, but there are lots of interesting opportunities to take advantage of waste.... be it solar, geothermal or even garbage.

We're just not desperate enough to go through the trouble, that's all. I've built a system that makes it quick & easy. Now that I'm setup it only takes 5-10 minutes a week, tops. Not bad for 2-3K yr in savings.

Just when things are going great, some SOB cranked their door into mine in the parking lot... no note. There was a blue Honda beside me this AM, it's there pretty much every day. I'm going to check for a black mark on their door tomorrow morning.

If there IS one, I'm going to slash all their tires and burn their house down. It's the only reasonable response

If it's a Honda the black mark is not important. Just do it.

Ok, please excuse my ignorance, but why can't you just filter the vegie oil and drop it straight in the original tank and drive away? I know little about diesel engines, but I'm planning on ML diesel shortly.

True enough! The fact that their car starts every time they turn the key, day in, day out is enough to drive me crazy... that was especially true when I was driving my Regret-a-Jetta

There is a a lot of evidence that injecting vegetable oil into a cold engine will do damage over time. Even if the oil is heated, if it gets on COLD cylinder walls it causes coking on the piston ring landings and eventually stuck rings. It'll work, but it's frowned upon.

Some people do what's called "single tank" conversions. They use heated filters, injection line heaters and special injectors. They'll work in some warmer climates, but I don't know a whole lot about them because I couldn't get away with one in my climate. There's an outfit in California that does really sketchy one-tank systems: Lovecraft. They are the MotorMeister of the veggie conversion world. That's the problem... lots of peopel have cobbled-together systems that they think work GREAT because the car runs. A diesel will run on turpentine and horse pi$$, but it's not good for it.

Some people also run a 50/50 diesel/veggie mix, or even 25/75 gasoline/veggie. That seems to work great in warmer climates, and Mercedes seem to work well with blends like that. VWs, not so much.

In my case, I have a parallel fuel system for vegetable oil, and can just switch fuels once the car is up to temperature.
I switch back to diesel before turning the car off, and for 2 minutes I'm in a "Purge" cycle where the vegetable oil is being flushed out with diesel, going back into my veggie tank. Once the "purge" is done, I'm I can switch the car off. It's got 100% diesel in the system so it will start fine.

After some minor "tweaks", I should have that down to 1 minute in the winter, 30 seconds in the summer.

Didn't old Otto design that motor to run on peanut oil?

I like the idea, would do a truck like that

Actually I think the first diesel engine ran on coal dust. Imagine that! But yes, the first ones ran on a variety of fuels, including peanut oil. The idea was to make a compression ignition engine that could be run on whatever fuels were on-hand. We're just coming full-circle.

FWIW, the best oil I have EVER run was peanut oil from a szechuan restaurant in Montreal. Car idled 200 rpms higher and went like the blazes. Never understood why.

As for trucks, the dodge cummins are the BEST to run, as long as they aren't the 98.5-2002 engines with the VP44 injection pump. As long as you buy one before or after those years, they are the best trucks to run veggie. Some say the Cummins 12v 5.9 is the BEST engine to run on veggie, car or truck. Ford Powerstrokes are great too, but the Chev 6.2, 6.5 and 6.7s have injection pumps that are REALLY sensitive to heat & viscosity.

Great job

I've been looking to do this on my truck and you write up might be the motivation I need.

What kind of truck?

You can buy complete kits for just about any diesel vehicle. There are 3 main reputable companies: PlantDrive, Frybrid & Greasecar.

I try to steer people towards PlantDrive. They use excellent components and their product support is unparalleled. Craig Reese runs the US side of the company, and he is a great guy.

For more info, here are a couple forums:

This one has been around the longest:
http://biodiesel.infopop.cc/eve/forums/a/frm/f/159605551

However, it's become cumbersome and poorly moderated. A few of us just started a new php forum that is picking up steam:
http://www.burnveg.com/forum/

Either way, PM me if you have any questions, Chris. I'm headed out on vacation but will be back in 10 days.
