We've assessed carefully the effect of taking Iranian petroleum off the market, both so that we can monitor those effects, but also so that we not have an unintended effect of providing Iran with additional revenue through higher prices of oil.

For starters, while many car engines currently can run on a blend of 10-percent ethanol and 90-percent petroleum gas, bumping that cocktail to 15-percent ethanol, or E15, will result in a warranty and liability migraine for car owners whose older models are unable to digest the blend.
