Hello, my name is Daniel McAmoil. I am a grain farmer and a cattle rancher from Northwest Kansas, Penokee to be exact. In April of 2006, I invested in a Chinese screw press rated at 6 tons a day.  I bought sunflower seeds off the open market until I could harvest my own sunflowers that fall.  In August of 2006, I traded up to a 10 ton press and, to-date, have made and burned over 25,000 gallons of fuel.  The 10 ton press is pressing right at 25 gallons of sunflower oil an hour with high oil content seeds. It makes good use of the dead of winter for my farms right hand man ( my son in law Jason) to make fuel for the summer farming use.


Due to the 1000s of people who scan over my site and feel they have the concept mastered by some random gas mix ratio off the top of the head or what some bar stool expert told them, and just take off and run,,,,,, here are some words of warning.. 

They call me after the fact a $20,000 engine in there tractor, truck or boat is not running right and are asking for my help to save the engine. So far 99% were saved before major damage and the folks now have a hydrometer and are using it for every batch of fuel used.

Trust me when I say that I have seen some totally crazy concepts to get around common sense to make bad fuel run. I have seen fuel filters cut apart and filled with steel wool, a gallon of injector cleaner used for every 20 gallons of bio diesel burned. I have visited with people who have destroyed 5 or 6 injection pumps in less than 2 years and don't feel they have a problem with the fuel they are making and using. People wake up! 

At this point before we go along into my fuel concept,, I must stress that veg oil is not the same animal from one oil to another.  I have seen sunflower oil from the same field, grown the same year from the same seed vary 20% in the needed unleaded gas to make a usable fuel.

Soybeans vary the most from the little I have worked with this oil.. Seed brand, and seed number,, soil,, growing conditions, planting date all end up with a different oil to make fuel from.

Then you have to test your fuel with any changes with the air temp. If you mix up a batch of fuel on a 80f day,, and it turns colder the next morning down to 50f,, your might be in trouble and might need to add some more gas. 

You always test your fuel for the lowest temps you will be running it with! 

 Even if you are mixed up with a 50% gas 50% raw oil your lube value is still 16 times better than the newer fuel we have now for injector pump lube. 

So always use a splash more gas than you feel you will need.. Its called a safety margin!

So a hydrometer is a must.. Not using one you are risking your engine.!!!!!!! My time and reputation.

Please understand that the fuel thickness and flow is important on how well the engine injectors can process it to make it into a clean burn. If its too thick it will deposit huge amounts of carbon, and jello in the crankcase.. Sticking rings,, valves, and even sealing off the oil pump suction screen..

I got my hydrometer off eBay,, for $25.00  After many people got ahold of the wrong one,, or had to pay $299 for a food grade hydrometer I got on the Internet and found this site which is the lowest priced one I have found to date

Its darn cheap insurance and a must to make my fuel !

Now for the fellows that want to use used cooking oil.. WVO

It works.. but not as good as raw oil.. The heating of the oil over time brakes it down,, and cooks out allot of the hydrogen and oxygen.   So its performance will match #2 diesel at best.

You have to also factor what was cooked in the oil. If it had fish, or meat in it you will also pick up the fats from what was cooked.. This adds another wild card to the end result. I do not fully support the use of used cooking oil but have allot of people taking my concept and running with it with great results..

All are happy with the end results and all have all commented that my system added to what they did in the past totally changed the process and made it easier and faster with better fuel.  Please use a hydrometer and watch out for salt in the cooking oil..  A high level of salt can pit piston faces, valve seats and etch cylinder walls.. How to test for salt you ask,,,, taste the oil. If you taste some salt no problem, but if it is as strong as a fresh potato chip its to salty to use and will need to be washed like the system of chemical bio diesel.

With the value of sunflower seeds markets value around  $0.13 to $0.14 lbs. area..  This puts the value of my farmed raised fuel in the $.58 to $.62 per gallon area.  At this moment oil seed market in my area is at $0.22 and pushes my cost per gallon to around $1.86. This figure changes daily with the seed market along with the soybean meal market swings. Only once since my start could I buy pump diesel cheaper than I could make it for and that time span was only for a few weeks.

Using the little DieselCraft centrifuge totally changed the home made fuel effort. I cant remember the last fuel filter I was forced to change out due to dirty fuel. 

That first season,, I was buying case lots of fuel filters and carried 3 or 4 spares in the cab of everything burning super fuel.  Never knowing from one batch of fuel to the next if it was good or bad. That was a real pain.. Once a 500 gallon storage tank got some bad, dirty fuel in it the problem would last for weeks or until one would just empty out the bulk tank and clean it and start all over.

All the people who have shifted over to using centrifuges are seeing a better fuel over all from just settling or using bag filters.  There is something going on inside the centrifuge or the pressure pump that seems to condition the fuel and make it another step better.  Some feel is just the added mixing of the fuel by being pumped more times going into the centrifuge.. But I feel the rapid pressure changes the fuel sees going from a bulk tank,, to 100psi,, and back is doing something with the microns of the fuel itself.  Make production notes and lets talk it over a cup of coffee sometime.

The more people work with raw veg oil as fuel using the  (RUG) system,, the more we are learning.. After all, the higher schooled folks keep saying we cant run this fuel.. It has to be chemically modified are still overlooking there mistakes back in the early 1970s of not seeing why raw oil fuel did not work.

Back in the early 1970s,, about every school of higher learning,, took a new diesel engine,, and poured in pure raw bean oil into the tank and after about 4 hours the engine glued itself together.. There thinking was and to this day,, its does not work!  No shit.. They never looked back at why it did not work.. Its not the compounds of the raw oils,, it the fuel thickness! A diesel needs the fuel sent into the engine in a super fine mist, or fog.. The finer the better.. Raw oil just went in as a thick pencil stream, or even droplets. Carbon, stuck rings, stuck valves,, jello in the crankcase were the end results along with a dead engine.


How my system works!

Unlike the chemical process that the bio-fuel fellows use, I keep the glycerin in the oil for the added power output. The difference is almost 40% gain with some engines with  greater power and mileage than commercial bio-diesel with the glycerin taken out.  I'm just using unleaded gas to thin the sunflower oil to match the thickness of #2 diesel so the injectors can do a good job of fogging it into the engine. I use a hydrometer calibrated from .820 to .890.  Normal #2 diesel floats the hydrometer at around .850 to .865.  ((I'm finding that most of the diesel fuel I'm getting this summer is down to .820 which tells me we are getting allot of jet fuel blended into our #2 diesel)).  I just press, filter, add gas and go. No chemicals, washing oil, drying oil, or any engine adjustments, just as simple as can be!  That and there is no nasty slim,, soaked in acid to try and get rid of. I have gotten word that the EPA,, has found piles of this byproduct behind peoples sheds from the chemical system to make bio diesel,, and charged the owner over $20,000 to put it in toxic waste drums and haul off! Moon suits and all..

With this fuel system it can be used at 100% sunflower fuel with the gas added,, or any blend with #2 diesel at any ratio you can think of without any worries of problems, mixing, or settling.  I can safely say, that once the gas is added, it changes the veg oil to another compound that is not showing any brake down even after several years in sunlight!

Every engine I that I have used it in gains at least if not more than 25% power, and fuel mileage.  My new R75 Gleaner with a M11 Cummins used 1 gallon an acre on regular #2 diesel, in comparison, on sunflower fuel, it uses just a tad over 1/2 gallon per acre.  My '98 Dodge Pickup went from 16mpg with #2 diesel up to 24-26mpg on sunflower fuel.  It's unbelievable!

Filtering vegetable oil in the winter time has started a new round of problems.

At this time, I am using a small centrifuge to do the final filtering of my sunflower oil. I was using bag filters down to 5 micron, but the oil is to thick in the winter temperatures at my shop to pump oil into the 5 micron filters. My system now is to filter it down to 50 micron and then pump it to a mixing tank, add the unleaded gas and from there pump it into my centrifuge to clean it down to 1/2 micron.  So far if I allow the centrifuge 3 passes of the fuel, its doing a great job of cleaning up the fuel and and now having no filter plugging on any engines.

The centrifuge website is

This is the self cleaning centrifuge I'm saveing my money for to sit right under the press as its crushing oil and have clean oil right from the get go..

They have a little movie showing it running.  They are not cheap!! but will last 2,000,000 miles on a large semi truck engine so they will last forever without the road shock and engine vibrations.

Every farmer should look for new ways to keep the cashflow in their pockets!

I feel that, because I can use all of the meal by-product to feed my cow-calf heard, I'm making farm raised diesel fuel for just a tad over $2.00 a gallon. (That's after I figure back in the meal value and the performance increase.)
