He sounds like a very interesting man. Update us after a while and let us know how the WVO adventure is going...

Okay, I got an email about a week ago from my dad. He helped my cousin move from Albany. NY to Jamestown, NY. I will quote his email. BTW, LV stands for Little Valley, NY, not LasVegas.

quote:
Went from LV to Albany NY, picked up a enclosed U-Haul trailer, loaded it with Lindsay's stuff and hauled it back to Jamestown. Trailer was full, trunk was full and back seat was full. High gear, cruse control set at 70 mph, all the way back with the loaded trailer. Dropped down to 60 on one hill. Switched off the veggie at Salamanca exit with a total of 700 miles on about 17 gallons wvo. About 41 mpg. If I was not pulling the trailer, bet I would have been up about 48 to 50 mpg. Have enough diesel left in the diesel tank to go back to Albany and return, not pulling a trailer.

The VW pulled the hills like there was nothing behind it.

I think most people are just scared to do this kind of thing. I haven't done any real research but have seen enough on tv shows and through a friend who had done his homework to consider doing it myself. My only problem is I live in an appt and don't have room to store the veggie oil. I drive enough miles that it would be worth it to me to put some money into getting this going.

I think my vehicle of choice would be a mid 80's Olds Delta 88 diesel 350, since I have so many parts that fit those cars. Maybe I could even convert my gas 307 Delta 88 that I already have over to the diesel engine. The later diesels didn't have the head bolt problems that the earlier ones did, and besides that issue most problems were due to customer error.

If you've got a bosch inline pump, you are laughing.

The (Lucas Style) IP in my Nissan is $4,800 if I mess it up and ruin the thrust bearings.

Even the switch to 20% bio diesel where I work and is clogging filters before service intervals are due. Can't imagine trying to deal with pure veggie oil, other than how hard it is to clean off a fry pan when it gells?

wileyE,
I think that the crux of your issue is...switch to 20%.

I think that the esters might be cleaning out tanks and oxidised rubber fuel lines etc. after running dino.

Either that, or your bio has soaps/glycerine in it.

Using WVO is a very customised approach to running a vehicle, you need to be on top of your game completely.

I have an idea on how to keep your tank of WVO warm...
Where I live, not sure about you guys in the warmer parts of Canada/USA, in the winter it dips down to -41*C/-41*F regularly, and it does get colder than that. We have block heaters that you plug into the wall.

Maybe you could use a block heater or a magnetic oil pan heater if the tank is metal.

I would be interested in doing this in my truck if I do a diesel swap.

During Katrina I knew a guy that would mix (clean) Veg Oil in with his diesel fuel to strech it due to limited supply

He suffered no ill affects with his Ford engine

This was a emergency but he continued the experiment to see what would happen and he did not incur big problems

I've read stories where in Europe, the price of diesel fuel was sometimes higher than cooking oil. The savvy owner would buy his fuel from the supermarket.

WVO has become so popular, that places like San Francisco now have less WVO that there are people who want it. I believe the city has contracts with many restaurants to provide WVO for their city vehicles.

You could look at electric water heating elements for heating the drum of grease. I would select a low wattage 240 one and run 120V. It may screw right in the bung, or perhaps with a bushing.

For heating his drum, get one of those heating wraps, I use one in the winter for "drying" out my WMO and they work great.

Grease car should sell them and of course, Ebay. They average $120.

I would recommend relatively frequent lube oil changes, since WVO that gets into the lube oil reacts to form solid "goo" that will eventually cause bearing failure if not noticed.
At least keep a very close eye on viscosity. Use one of the cheaper lube oils like dino Delvac 1300 15W40 or Supertech 15W40.

He said he will have to run the first 5 miles on diesel and then when the cooking oil is warmed up he can switch over.

He told me that there are limited cooking oils that can be used and canola oil is prefered. He has already set up a deal with a local restaurant and a grocery store so he can pick up their used cooking oil. All he has to do is filter it with a regular water filter that you find under a kitchen sink. One filter lasts for 50 gallons. He figures, with the current price of diesel, that this system will pay for itself in 3 months and after that it's money in his pocket.

He has also been told that the cooking oil will clean his injectors and other fuel related parts of his engine.

Many moons ago I read about how people were buying new vegetable oil or cooking oil for their converted diesels. They'd get the oil from a store. Somehow, it was cheaper than diesel fuel, so it was a nice way to circumvent the road tax. Not sure about the reality of it though.

UK and Europe they are, as diesel is so expensive.

So successful, that the law is now that you have to register with their version of the IRS and pay excise on the vegetable oil.
