Preparing for Winter

Might be a little soon to be talkng about this now, but I have been very happy running an 80 / 20 blend of WVO and RUG in my 240D and I am prepared to keep running it this way through the winter if I can.

So, this weekend I took a batch of fuel and placed it in the freezer. My freezer is about 10 degrees Farenheit. My fuel froze solid. It was about as hard as peanut butter. I then placed a batch in the refigerator, which is about 37 degrees Farenheit. The fuel turned into a thick syrup about the consistency of ketchup or mustard.

I don't see how I can run this blend in the cold Philadelphia winters. I am thinking about running 70 / 30 WVO and RUG and seeing what happens, but I was curious what the rest of you are doing - assuming you live in the north east where it gets cold.

Also, I have to say, I am NOT looking forward to the hassle it will be to collect and filter WVO in the winter. I assume I will have to find a very heated garage to work in, and everything will have to thaw out before I can remove it from my collection tank and filter it. Working with this fuel before I mix it with RUG is going to be a pain in the a$$.

If it is too much of a hassle, WVO might have to be a summer fuel only.

I have no personal experience, but I recall reading posts here before about WVO fuel heaters to take care of this problem. Did you look there yet?

I live in your area and I have done the same experiment with the same results.

From my reasearch I have found the only way to run in the cold is to go with the 2 tank heated system.

I am going to run diesel in the winter.

Cheers,

Bill

better quality oil will stay liquid at lower temps. you could also cut w//any amount of diesel/kero, instead of gas. dont add more than 20% rug, ive heard.example- 60% diesel, 40% wvo. and use an additive like power service.

I have read that WVO cut with diesel can produce wax. I did an experiment myself and it seems some diesel does have wax that will fall out after about 2 weeks while other diesel doesn't contain any wax.

I'll have to try the fridge experiment with the K-1.

Cheers,

Blends and cold temperatures do not get along. Single tank, I'd not use VO at all. Either blend biodiesel with kerosene/diesel, or go straight petroleum. Or convert to two tanks, and run a blend in the heated system.

My hat's off to you guys

I find this section of the forum to be extremely interesting and I think it's gret that you guys are doing something to lessen our depedence on foreign oil and to pollute less. I don't know if I would have the patience to do all of this work to make my car run, though.

I bet it makes for some interesting bar/party conversations though.

Has anybody tried running 70 / 30, WVO and RUG? My mix of 80 / 20 is thicker and more viscous than diesel fuel. I would think that 30% RUG would not make the fuel too thin and still provide lubrication for the pump. I am not sure how it would burn though, but my 80/20 mix burns just fine.

OLD 300D----I know you burn home made bio. Why cold can get get before you have problems with home made bio? With my home made bio there should be no problem mixing diesel in colder weather?
