Right. But that's motor oil! In particular used
motor oil. Used motor oil is worse than new motor oil, and new motor oil is worse than crude
oil, for the environment.
You might argue that used motor oil dissolves into the water faster than crude oil since it doesn't contain tar, but that actually means that it more
quickly releases the higher concentrations of toxins, including the toxins that crude oil doesn't contain.
Furthermore, half of crude oil spills evaporates into thin air. From there, the oil separates into different forms. A great deal of which becomes
semi-solid tar, which is a nuisance, but as far as the environment is concerned the tar balls retain their chemical properties for longer, allowing
bacteria to eat them.
And that is not the only source for this info..you can find it also on this University of Georgia website
Be sure to read the entire documents you post:
EXPLANATION: Backyard mechanics dump more used oil into Michigan's environment each year than the Exxon Valdez spilled into Alaska's Prince
EXPLANATION: Oil spills account for only about five percent of the oil entering the oceans.
The Coast Guard estimates that for United States waters sewage treatment plants discharge twice as much oil each year as tanker spills.
During the last decade, more than one billion gallons of oil spilled worldwide.
Land runoff and recreational boating account for nearly 3⁄4 of the 5,000,000
gallons of petroleum released into the oceans annually

Here's what makes used motor oil different than crude oil:
Like several individual PAHs, waste crankcase oil has
been shown to be mutagenic and teratogenic . The
results are mixed, but some immunological, reproductive,
fetotoxic, and genotoxic effects have been associated
The concentration of various PAHs is much higher in used
oil than in (fresh) lubricating oil . For example,
Grimmer et al. reported concentrations of dibenz(a,c)-
anthracene, 4-methylpyrene, fluoranthene,
benz(a)anthracene, benzo(e)pyrene, benzo(g,h,i)perylene,
and benzo(a)pyrene, respectively, 36, 49, 253, 720,
1,112, 4,770, and 7,226 times higher in used compared
to fresh oil .
As an oil used in a crankcase, motor oil breaks down to
give a wide variety of oxygenated and aromatic
hydrocarbons . Other organic compounds found in
waste oil include toluene, benzene, xylenes, and
ethylbenzene. Also present are organic and inorganic
compounds of chlorine, sulphur, phosphorus, bromine,
nitrogen, and metals such as zinc, magnesium, barium, and
lead resulting from oil additives and contamination
during use or disposal .
Used engine oil is a contaminant of concern, with large
volumes entering aquatic ecosystems through water runoff.
The major source of petroleum contamination in urbanized
estuaries comes from waste crankcase oil . PAHs,
heavy metals, additives and antioxidants, trace levels of
chlorinated solvents, and PCBs have been detected in used
engine oil . As mentioned above, naphthalene,
benzo(a)pyrene, fluorene, and phenanthrene are common PAH
components of used motor oil .
Did you see that?
"espectively, 36, 49, 253, 720, 1,112, 4,770, and 7,226 times higher in used compared to fresh oil"
It's called the hydrocarbon pollution intelligence test...[no, really!]
Now then...If the US Geological and Oceanic survey figures are right and the Gulf contains about 642 trillion gallons of water...and if the
minimum independent flow rate estimates I used are anywhere near right..and I ask you to check my numbers...but if they add up and this IS the best
"conservative independent" base-line calculation for what damage has been done so far ...that means in the last month the Deepwater Horizon spill
has polluted/contaminated 10.43563068920676 % of the Gulf Of Mexico.
You forgot one thing. The water cycles out of the Gulf and into the larger ocean networks.
One more thing: You speak as if its all already done for, although most of it is still concentrated in one area.
