RT,

Sounds like a great idea. What do you use for a pump?

Have a great day,

I have been burning every combination of fuel know to man over the past several years.
First motor will burn straight but it can be difficult to start below 20 degrees. You can try adding mineral spirits or diesel to thin it out .
As of recent I have been burning used canola oil straight , also dumping in used atf and motor oil. Every so often you really should burn a tank of diesel.I believe a long diet might soot up in the pre chambers and I say might.
The filtering process is quite simple. A 20 gallon parts washer tank and a oil furnace filter recirculated for about 24 to 48 hours. The dirty oil longer. I now am setting up a simpler filter that is similar to the fuel filter. This will be a second step after the first.
Synthetic oil burns the same as anything else.
Never had any problems with pumps, injectors, gelling, starting, smell, or smoke.

Go for it.

Larry,
I haven't done this yet, it was just a suggestion. Depending on what kind of filter you use it could even gravity feed if you can wait a week for it to flow.... McMasterCarr has many different pumps or maybe a drill-powered pump or even an auto oil pump could be used.
Ricali,
What specifically do you do to use straight used WVO? Very curious about this given your location, western MA, gelling issues, etc. Thanks, RT

Cummins has a system that meters crankcase oil into the fuel supply to be burned. One then replaces the lost oil with fresh oil. This allows for some seriously long drain intervals since the oil and its additives are constantly being replaced.

"The Cummins CENTINEL Advanced Engine Oil Management System allows engines to go 525,000 miles between oil changes and 100,000 miles before changing the filter. with less time and money spent on oil system maintenance."

rwthomas A little history first. A few years ago a friend of mine gave me a rabbit convert. that was tired. I decided that Volkswagen needed a diesel conv.. So after a total restoration and installing a diesel, he said why not something really crazy like burning french fry oil. Well thats history and the saga goes on.
So the answer is no nothing other than complete filtration and adding power service. As for gelling there is a hundred gallons sitting in my garage and no sign of gell. Our temp was down to about minus 15 last week. I do however not use it under about 10+. All my oil comes from a known source and does NOT have any salt in it.
Another little fact is that viscosity has nothing to do with actual weight as in pounds. I believe gas weighs about 6 pounds per gallon and oil weigh about 6 pounds per gallon. ( am I correct from my aircraft training??)

Ricali:

I'm already hooked, but need a couple of questions answered:

1. About how many miles have you done with alternative fuels and has this impacted the injectors more than normal?

2. How do I find WVO that doesn't congeal or gel during winter months? I was under the impression that it all did. The restaurant that I have permission to work with.... the stuff looks like vaseline.

If you use waste crankcase oil doesn't it have dirt and metal particles in it? Is it a good idea to run this through your injector pump? Are there filtration techniques which suitably remove the particles to make it safe for the IP?

This machine will clean the used oil, the only draw back is that it costs almost $30,000:

i started by putting samples in the freezer. My wife really liked that.

Miles driven probably in the 100,000 range. About 50k on my present 95 E300.

Pump or injector problems none. Again not for faint of heart. There ALWAYS is a risk.

Dirt in the fuel filters has not been high and an average filter change at about 12k.

I also have a strong magnet on the side of my filter tank. This does not take of none magnetic particles.

The whole theory behind filtering is as the filter becomes clogged it filters even finer. So filter filter, filter and when done filter again.

A starting point, buy 5 gallons of new canola or veggie oil and dump it in.

Hey folks, what about all the acid &
combustion byproducts (liquidy stuff) that are in used motor oil and you can't filter out?

Is this an area of concern?

Aivars

Just filtered 8 gallons of used motor oil today with one of the cylinder filters from Greasel. Worked awesome. Poured a couple of gallons in the wagon. Running a hundred miles tonight and will see how it runs.

I was listening to NPR a week ago, and they were talking with a guy in England who runs his Mercedes Diesel on used cooking oil. His neighbors say they always know it's him because it smells like fish n' chips when he starts it up in the morning and comes home at night . . .

diesel don,
what is a greasel filter? is greasel a brand name?

pklarc beat me to the question. I'm very interested in the answer.

The answer to the question about acids and other contaminants is that you are BURNING this as fuel, not using it as oil. As long as the particulate matter is removed, the other contaminants shouldn't hurt anything because the lubricity of this "fuel" is obviously adequate since it is engine lubricating oil.

Have a great day,

Here is the site for greasel.

Look around and you will find the filters.
