All the cheap dry-gas sold here was methanol based.
All the more expensive drygas sold here is isopropyl based.
Both ethanol and methanol are corrosive. Somewhere someone deemed that E-10, M-5, MTBE-15, and ETBE-17, were safe for all vehicles.
Does anyone here notice that we're adjusting the percentage blend for corrosive level? Would it be safe that say the M-5 is just as safe as E-10? or E-10 is just as corrosive as M-5?
What bothers me is that either will bump your octane 2-3 points. If this is so, why am I paying more for E-10 87 octane(which is a blend of 84 octane gasoline and 10% ethanol)?
Where's my per gallon fed/state 10% tax break?
I wonder what the next fuel additive fad will be once the demand of ethanol exceeds its supply.
Gotta run and rebuild another carb, and replace another mechanical fuel pump. I guess that there %'s are a little high for certain cars!
Biomass butanol, a high octane fuel:
without the BTU hit causing lower MPG,
without the corrosion issues of E or M,
without the cost of FFV vehicles,
without the transportation or storage issues of E,
