Yeah no worries, I guess anyone who burns this stuff has no right to complain about anyone driving an SUV. My eye's don't water driving behind one of those!

The $hitboxes are actually quite clean for the environment..........the problem is the volume of CO2 they produce due to the poor fuel economy. But, at $4.00 per gallon, the mileage that these vehicles travel is going to drop dramatically............there really is no other choice. It now costs $0.30 to drive an Expedition one mile.

The problem is people have been convinced CO2 is a pollutant.

http://www.dieselnet.com/news/2007/04epa.php

" In one of the most important decisions in environmental law, the US Supreme Court has ruled that carbon dioxide (CO2) is a pollutant and that the Environmental Protection Agency (EPA) has the right to regulate CO2 emissions from new cars."

Straight from your pet agency, too

Don't confuse him with the facts, Michael...........

I reject your reality and substitute my own!

Nobody said they were right about everything.

Fear not Forced........you're batting at least .800 around here.

I'll throw a couple of thoughts into the ring.

1) Regular diesel fuel most certainly does have at least SOME metal particles and dirt in it. Last time I checked ALL of the pipes, pumps, tanks, etc. used in producing, storing, transporting, and dispensing diesel are all made of various metals. Any an all metal machinery wears and sheds metallic particles and keeping it dirt and particulate free is obviously impossible. Why else would there even be a filter in the fuel system? And if there are no particulates in the fuel, why would the filter ever need to be changed?

2) WMO is going to have more metal particulates than diesel fuel, but that is why it needs to be filtered. Filtering to 2 microns more than is sufficient since the fuel filter already allows particles larger than that to pass without harming the pump and injectors. Filtering doesn't have to be expensive if you're in no big hurry about it. A 2 micron sock filter is cheap and will filter tens of gallons of oil before needing to be washed out (inside out with clean fuel or RUG) and they can be washed and reused a dozen times or more.

3) Acidity can be an issue, but if you're changing your oil frequently the amount of acids in the oil is low enough to not be a concern. Test your used oil with a PH strip and compare it to new. Not enough of a difference to be concerned with.

4) Used oil itself is not a hazardous material. As long as you keep antifreeze and chlorinated solvents out of it (brake cleaner for example) the EPA defines it as a NON-Hazardous waste. The company I work for has thousands of gallons a year hauled away by a recycler and they test every tankful before hauling it. If it tests "hot" for the contaminants mentioned above it has to be classfied as hazardous. Otherwise it is considered non-hazardous waste. Same for ATF, gear lube, and pretty much all petroleum oils. All the recycler does is heat it to boil off any water, filter it to remove particulates carbon and metals, and then they turn right around and sell it as "on-spec" furnace fuel. I've personally inspected their facility and seen the process first hand.

5) Motor oil adds lubricity to ULSD - as demonstrated by the lubricity chart posted in the thread on fuel additives. That applies to well filtered waste oil as well. Personally, I wouldn't run it above 25% WVO mixed with 75% diesel in most climates without heating it. For the exact same reason I wouldn't burn unheated veggie oil. It increases viscosity, makes for harder starts, doesn't atomize as well, can lead to coking, etc. But if it has been well filtered and dewatered, up to around 25% should be no problem IMO.

You know, I just read that start to finish...
here's my thoughts.
Magnetic Lead? W.T.F. (full stop)
Non magnetic stainless is the low end? Tell that to my finance department that just shelled out $10K for a 16x22x0.5 inch double planar ground magnetic stainless insert for my wafer prober...

Cleaning used motor oil? I kinda like the bio-diesel guy's method: after reaction, before wash, blend in the oil. The wash *should* clean out the soot, metals, and most of the detergents.

Magnets won't cut it.
Forced is basically right about this (much as I'd rather disagree just because).

CO2 is a combustion byproduct... If it is now a pollutant then I'd like to slap a gross polluter tag on Rush Limbaugh, and Michael Moore.
And Congress.
...
And the senate...
can't forget the lawyers... (you know I could go on forever here).

Cheers,
-nB

Make it easy on yourself: use two layers of filter: a used jean leg double-stitched closed on the end inside a 1-micron sock filter.

The jean leg will last about 25 gallons (filters to about 5 microns) and the sock filter will last about 100 gallons before you have to rinse it. After you rinse it you're good for about another 75 gallons with the sock filter.

Here's a page from the owner's manual.

Personally, I would never use anything but what the manufacturer recommmends in my 1982. I was just marveling the other day how brand-freaking-new it seems. I love that car, and it just isn't worth it.

But, another car with 250K-300K miles on it... or something that only has another <100K left in it anyway, that might be a different story.

It didn't say anything against adding used engine oil.

P E H

Probably because they (correctly) assumed that no rational person would consider putting used oil in their new new $30K vehicle.
