* Notes:
Flex fuel is fuel containing ethanol. MTBE and methanol were also used, but have been all but phased out as of now.
A common, up and coming name for flex fuel is E85 (85% ethanol, 15% Fuel C).
Biobutanol has recently been in the news as BP and DuPont are forming a partnership to develop this fuel described as “an advanced biofuel similar to ethanol but easier to integrate into existing fuel supplies.” The properties and functionality of the compounds listed above in biobutanol are similar to that of E85: products on the list above are fine to use in biobutanol applications. Further test data to follow.
