I agree fully with the above I disagree here. WMO is just a used portion of the petroleum stream, therefore the seals used for diesel fuel are the same seals used for motor oil, used or new. However. the problem with burning WMO, aside from ash and coke, is most people who burn WMO...

A recycled compressor tank, or propane tank is a better solution. Just cut a 2" hole in the top and weld a 2" tapered thread female to it, then screw on a fuel tank cap adapter, which you buy at an auto parts store. The fuel tank cap is vented, but maintains a 4PSI pressure differential...

Wreckerman, you must have been lucky running that blend, because blending WMO with WVO can make large quantities of glue that can ruin your IP, injectors, and entire fuel system. If that blend were left to settle for a month, then most of the glue will have settled out, but the next batch might...

Poly tanks are sensitive to UV, but painting them black is a good idea to reduce UV damage while increasing IR gain. They will get stiff in the winter, and more likely to crack after a few years outside, so you may want to plan on replacing them every few years. Keeping your settling tank warm...

Thanks, I think it is just human nature to want to kill people you disagree with, instead of giving everyone a fair shake. Yes, I did a lot of viscosity and specific gravity testing, and I videoed some of it, and it is up on my YouTube Chanel. Basically, gasoline blended at 50% with either...

Just dumping various oils into a barrel is fine, because they will go into solution with each other, and will not separate except through distillation. But, the more viscous the blend becomes in your sludge barrel, the less likely contaminants will precipitate out. So, one month before you use...

Any diesel engine can theoretically burn any waste oil. Synthetic oils and waste motor oil (WMO) burn the same in any diesel engine. However, all waste oils burned as fuel should be de-watered and hyper filtered. Most people who burn WMO in a diesel engine blend gasoline at 15-20% with it...

It looks like nice setup, and since you are processing just your own oils, then you surely have control over the reduction of water, and other contaminants in your waste oils. However, the biggest problem with burning WMO is it tends to be burned from over use, which polymerizes the oil. If...

You might consider blending gasoline with your WVO. I have been doing it for 6.5 years on a 83 chevy van with a 6.2L DD engine. I went to blending for the much the same reasons that you are trying to electrically heat your WVO; because biodiesel chemicals are expensive, and toxic to use; and...

There are a number of DIY SBC oil pump conversions on the web. Just google it.

I agree there, but I back-flush my fuel filters in situ, so I have not had to replace them in 3 years either. I am not well-funded, so I need to make my operation as cheap as possible. So far blending waste oils with waste gasoline, and recycling all of my filters means my fuel is free, after...

I know from bitter experience that blending waste oils with solvents in the fuel tank is asking for trouble, because when you blend solvents, such as gasoline, kerosene or diesel fuel, with waste oils, even highly filter ones, then precipitates can form in your fuel tank, which is not where you...

Are you planning on burning your WMO straight, or do you plan to thin it? If you are going to thin it, then you may find thinning it first will cause the water to precipitate out in a few days of settling, so you will not have to boil the water off. Also, thinned oil will pass through your...

I run my waste oil blends backwards through my sock filter, so that I can back-flush it with gasoline afterwards. I had been using the same sock filter for 3 years. I recently changed it to see how the filter was surviving with back flushing. It was fine.

WVO can react very negatively with WMO, but not all WMO. So, if you are going to run both, then I advise blending them together with diesel, or gasoline to thin it out, then leave the blend to settle for a month. When you carefully pour off the good fuel off the top, you may find a thick black...

Most of those who successfully run WMO for long periods of time on their engine run their WMO blends through a centrifuge. A centrifuge will remove sub-micron particles, which I believe are important to remove.

I have no idea what could have been done to convert vegetable oil to gasoline in a blender. it makes no sense to me. However, I can see making diesel fuel out of vegetable oil, by blending it with gasoline at 20%. I do it all of the time.

Very nice. I wish I had it. Since all your fuel started out clean, and may only have collected the odd particle and some water, then the water is going to settle to the bottom of the barrels fairly rapidly, so just do not pump the bottom 10%. Just get yourself a decent transfer pump (20gpm)...

Black diesel seems to run differently on different engines. I have an old Detroit Diesel n/a engine that cokes its injectors on black diesel in days; however, I have been on several forums where a large number of people report running black diesel on 7.3 PSDs without trouble. Most of those...

I agree, once you have added any waste oil to gasoline at 70% or more the resulting fuel blend should have plenty of lubricity. Brianp454. I would be very interested in a Viton seal kit for a DB2 IP, if you come up with such a kit. The DB2 IP has at least one silicon seal, which I know fails...
