all pumps that sell gasahol in TX are required to state the amount of ethanol (if it is above a certain minimum, I belive 5%)

curious... thought FFV vehicles used 85% alcahol...

FFV vehicles can run on anything from pure unleaded to e-85, which is 85% ethanol. Gas mileage is quite bad with e-85 though, because to truly use e-85 to its maximum potential you would need a higher compression ratio.

HoustonHemi,
no rebutal at all...that link just has a lot of hard to find information.

Since the factory stock 5.7 Hemi is running at a very rich air to fuel ratio of around 11
and 'best power' a/f is probably in the 12.5 to 12.9 range
and ethanol is stoichiometric at a little over 6
it is probable that blending in a percentage of E85 to the E10
could result in a E?? blend
that when used in a factory stock Hemi would make
more peak horsepower.....something like 5 to 12% more
....but the exhaust gas temperatures will go up too...and it is possible that the high temperatures will damage parts of the truck...maybe the catalytic converters will be hurt first....and then at some EGT the thin 'annodized' aluminum strip called the 'ring land' above the top piston groove might get soft enough to fail.....this could all happen very fast.

If you have some time to learn and maybe enjoy yourself at the same time
telephone around and find dealerships with
E85 capable 'flex fuel' Dodge Ram 4.7V8
and flex fuel E85 capable Nissan Titan 5.6V8

Ask to speak to 'their best salesman' and then explain that you are wanting to 'convoy test' their trucks with one burning E85 and the other truck burning 89 octane gasoline.

Whether it is a Dodge or Nissan dealership
a really good pickup salesman will have his interest sparked
and will agree to do it...especially if you suggest 'on a slow day'
