well im currently running 80% motor oil and 20% diesel in my ford f350 filtered down to 10microns and dewatered ,with a appleseed processor. coach next anyone doing any alternate fuels ?

When I do an oil change, most Owner Operators ask that I dump the oil back into their fuel tanks. I have always honored this request if their fuel tanks are at least 3/4 full. On a 100-200 gallon system, this translates into 5-10% oil burning. I can see oil burning, from the exhaust, above a 10% mixture.

Yellow Freight does this too, at a PM Service. All of their trucks, when they go for an oil change, get the oil pumped from the pan and into a "Spinner Device" that seperates the impurities and this gets pumped back into their fuel tanks.

If you are burning 80%, wouldn't it look like an oil burner going down the road? Your exhaust must be belching black oily smoke everywhere you go?? What am I missing here???

Aren't you concerned about what is coming out of the exhaust and into the air? I'm not a tree hugger, by any stretch of the imagination. I'm not here to judged you, only for a clarification on your setup that makes your vehicle so clean. What is an "appleseed processor" and how does it relate to an EPA Approved device? Do you have a link to this system being sold for motor oil burning?

Up in the Northeast there are "Motor Oil" burning heaters that are used in garages to heat the shops. These "waste oiler burners" are approved for heating and they do burn cleaner then you would expect. So, do tell, about what you have on your Ford Truck. If it makes sense, I could retrofit it for our service trucks.

nothing done to truck ... no excessive smoke from tailpipe..

How do you filter it to 10 microns? How/What is a appleseed processor. Is it done onboard or prior to travel? Google here I come.

Engine oil contains heavy metals that are not good for the atmosphere and our lungs.

At work, our piston engine oil was required to be treated as much more toxic than turbine oil, hydraulic oil, or fuel.

bill h is absolutely right about what's going into the air - and in addition to heavy metals, there are light metals byproducts (of barium, lithium, and calcium, among others); then there're the sulfur byproducts.

Not to mention the motor oil is full of the contaminants one changes the oil to rid the crankcase of; as for me, I'd not want to put those back into the engine. For one thing, many of them won't combust, meaning that they'll take up residence in the cylinders.

Back when I was a fuels and lube engineer, I used to tell my customers, "Oil's cheaper than metal." While the gap may be closing, it still is...

As for me, I send the waste oil out for processing/rerefining.

burning in shop furnace is healthier than in a truck with a exhaust system?

The Enviromental Protection Agency has allowed the use of "Waste Oil Burners" as a form of oil recycling. This oil recycling is the end stop for their "Cradle to Grave" rules.

FAQ from WasteOilHeat.com

From the EPA's own website.

Recycled used oil can sometimes be used again for the same job or can take on a completely different task. For example, used motor oil can be re-refined and sold at the store as motor oil or processed for furnace fuel oil.

One gallon of used oil processed for fuel contains about 140,000 British Thermal Units (BTUs) of energy.

Here is a link to the US ARMY website and a picture of a vehicle using a machine that pumps motor oil out of the crankcase and back into the engine fuel tank.



Here is a quote from the EPA's guidlines for used motor oil

quote:

Used oil mixed with a fuel other than diesel is considered used oil, regardless of whether the resulting mixture is to be used as a fuel or recycled. Mixtures with diesel fuel. Used oil mixed with diesel fuel is not considered used oil if the resulting mixture is used as fuel in engines owned by the persons who generated the original used oil. If the mixture is used as fuel by someone other than the generator of the used oil, the mixture is still considered used oil. However, the persons producing the original used oil are now considered "processors" and are subject to stricter storage and handling requirements.

From the way I read this, if it came from your vehicle, you can recycle it back into your vehicle. If you get it from somewhere else, and intend to use it for motor fuel, you must be regulated for that.

The above quote was approved through a joint venture with the EPA and TERC.
The TERC development was possible in part through the financial resources of the U.S. Environmental Protection Agency. These resources allowed AAAE to bring environmental compliance information to the transportation industry and the public through the web-site, fact sheets, news, calendar, and other documents on the web-site.

An issue with used motor oil, from your local mechanic, could be antifreeze or gasoling mixture in the waste oil recovery tank. I have seen the same oil pan used for both and dumped into the same recovery container.

If you took it out of your own vehicle, and you know that your going to dump it into your fuel tank, you wouldn't dump antifreeze or gasoline into the fuel tank.

You might wind up going through a fuel filter earlier. Most people change their fuel filters before they are plugged up anyway, so for most, this might not be an issue. The use of a filter restriction gauge is the best way to determine when to change your fuel filters.

In my research I saw 2 things that I can not find now for your preview.
1) used motor oil above 7.5% mixture of diesel and motor oil is not allowed.
2) the cost for recovery and reuse as fuel was pegged at .20 a gallon. That was based on the added fuel filter restriction before filter replacement AND the labor to remove the oil and recycle it.

In a tractor trailer, 10 gallons of motor oil would cost $2.00 compared to $50.00 for diesel. This is why Yellow Freight and the US Army uses these devices.

I would remind anyone who has a 2007 or newer vehicle that the use of only "LOW SULFER" fuel is approved in these vehicles. While our coaches do not fall into this range, someone who stumbles onto this in the future, through a search engine, might dump oil in their newer vehicle.

In the seventies, Dirt Bike magazine's editor, Rick Seamans, hired a lab to test various oils favored by motorcycle racers. Perhaps as a joke or whatever, they included something called re-refined oil, sold by Pep Boys.

It did really well, scoring near the top, surprising everybody.

Rerefined oil has the advantage that constituents in the base stock that break down are removed in the process.

The EPA webpage notes that particulates should be removed prior to using spent motor oil as furnace fuel. As an aside, external combustion is generally much more thorough than internal combustion.

I suspect the Army uses spent motor oil as fuel because that solves to storage and disposal problem, and because taxpayers are buying the new engines (and overhauls).

One should recall that Stanadyne recommends its additive for its IPs, but 2-cycle MO is acceptable. Anything else isn't, despite the lubricating properties of virgin HD MO and ATF.

As for me, I'd rather buy diesel fuel than spend my money replacing IPs or for top end overhauls.

I use 2 cycle oil and it works great, I have noticed an improvement in mileage but the most important is I know at least the fuel system now has some form of lubrication. I am adding 1/2 quart per ~45 gallons.
